Kelvin 8 Review: What the 8-in-1 Car Emergency Tool Does, Where It Falls Short and What to Keep in Your Glovebox

Our verdict

Yes, if you want a compact, rechargeable roadside tool that covers the basics in one device and you know its limits. The Kelvin 8 combines a seatbelt cutter, window breaker, flashlight, magnetic strobe, siren, small power bank and hand crank, from an established Canadian tool brand, and the offer page's $49.95 beat Kelvin's own store. But no window breaker can beat laminated glass, the power bank is small, and owner evidence is thin. The Kelvin 8 scores 5.1 out of 10, held back by overstated rescue claims and limited proof.

The short version

• An orange handheld emergency tool with eight functions.
• Seatbelt cutter and window breaker for escaping a vehicle.
• 4-mode LED flashlight with SOS, red strobe with four magnets and a 100 dB siren.
• 2,000 mAh power bank, rechargeable by USB or hand crank.
• $49.95 on 4 October 2026; three for $119.90 and five for $179.85.
• Kelvin's own store listed it at $53.99.
• 90-day money-back guarantee.
• Best trait: several useful roadside tools in one rechargeable device.
• Biggest drawback: window breakers cannot break laminated glass, and the page does not say so.
• Our score: 5.1 out of 10.

Pros & cons

The Kelvin 8 is a sensible combination of tools from a real brand. The cons are about limits every buyer should understand, and how little the page proves.

How it works

The Kelvin 8 is a multi-function emergency tool shaped like a large handheld torch. Each end and side carries a different function, and a fold-out handle cranks a small generator.

1. 01

   Keep it charged and within reach

   Step 1: Charge the Kelvin 8 with the included USB cable and keep it where the driver can reach it while belted in, such as the centre console or door pocket, not the boot.

2. 02

   Use the right tool in an emergency

   Step 2: Cut a jammed seatbelt with the recessed blade, break a tempered side window with the breaker tip, light the scene with the flashlight, or stick the red strobe to the car with its magnets to warn other drivers.

3. 03

   Call for help

   Step 3: Use the siren or SOS light to attract attention, and plug your phone into the power bank, or crank the handle to generate a little power, to make a call.

The escape tools

A recessed blade cuts seatbelts without exposing a sharp edge to fingers. A hardened tip concentrates force on a small point to shatter tempered glass. These two tools are found on most car escape devices and are the main reason people buy them.

The light and signals

The LED flashlight has four modes plus SOS, according to the page. A red strobe on the body can be stuck to the car with four magnets to warn traffic. A 100 dB siren attracts attention.

The power

A 2,000 mAh lithium battery powers the light and siren and can charge a phone through USB. The hand crank generates power when the battery is flat. The FAQ says about 3 minutes of cranking gives 3 to 8 minutes of talk time, depending on the phone.

What comes with it

The FAQ lists the device, a USB charging cable, an instructions guide and a carry case. The photos show a grey drawstring pouch.

How a hand-crank generator works

Turning the crank spins a small dynamo, which generates electricity to charge the internal battery or power the light directly. Human cranking produces only a few watts at most, and some energy is lost along the way. That is why a few minutes of effort gives only a few minutes of phone talk time. It is a genuine lifeline when everything else is flat, but not a practical way to charge a phone fully.

How much is 2,000 mAh?

Battery capacity in milliamp-hours is measured at the battery's own voltage, and some energy is lost converting it to charge a phone. As a rough rule, a 2,000 mAh power bank delivers perhaps 1,200 to 1,500 mAh to a phone. With most phones holding 3,000 to 5,000 mAh, that is roughly a quarter to a half of a full charge, which is enough for calls, messages and maps in an emergency. The same battery also powers the light, strobe and siren, so using those reduces what is left for your phone.

Who it's for

The Kelvin 8 suits drivers who want a simple, rechargeable roadside tool that covers several emergencies, from a breakdown at night to a power cut at home. It suits new drivers, parents equipping a teenager's first car, and people in areas with storms and long power outages.

It suits people less well if they already carry a good torch, a power bank and a dedicated escape tool, or if their car has laminated side windows and escape is the main concern.

Why the Kelvin 8 appeals

Car emergency kits often mean a bag of separate items that end up scattered or dead when needed. One rechargeable tool that lives in the car is appealing, and the hand crank removes the worry of flat batteries. The orange colour is easy to find in the dark, and the Kelvin name comes from a company with a Dragons' Den history and a range of everyday multi-tools.

Why vehicle escape matters

Being trapped in a vehicle after a crash, or in floodwater, is rare but frightening, and seconds matter. Seatbelt buckles can jam, and electric windows may stop working when water reaches the electrics. Escape tools exist for these moments. Understanding exactly which windows your tool can break, and keeping it within reach, is what turns a gadget into a real safety measure.

A typical roadside scenario

You get a flat tyre on a dark road. You pull over, switch on the hazard lights, and stick the Kelvin 8's red strobe to the back of the car with its magnets to make yourself more visible. You use the flashlight to see the wheel and call roadside assistance. Your phone is low, so you plug it into the power bank while you wait. This kind of everyday breakdown is where the Kelvin 8 is most useful.

The emergency scenario

The page focuses on the rarer, more frightening scenarios: being trapped by a jammed seatbelt or needing to escape through a window after a crash or in floodwater. The seatbelt cutter is useful here. The window breaker works on tempered glass but not laminated glass, which matters a great deal (see below).

Who gets the most value

People without any existing emergency kit get the most value, because it replaces several items at once.

Who gets the least

People who already have a good kit, and people buying it mainly as a window escape tool for a car with laminated side glass, get the least.

What it will not do

It will not jump-start a car, inflate a tyre, break laminated glass, fully charge a phone, or replace calling emergency services. It is not a substitute for a first aid kit, warning triangle or reflective vest where those are required.

Drivers in remote or rural areas

On quiet rural roads, help may take longer to arrive and mobile signal can be patchy. A light, signalling and a phone top-up all matter more. Pair the Kelvin 8 with a phone car charger, water, a blanket and a printed list of emergency numbers.

Winter drivers

Cold weather drains batteries, including phones and the Kelvin 8. In snow and ice, being visible matters, and being stuck for hours is possible. The flashlight and strobe help, but a winter kit also needs warm clothing, a blanket, a scraper and a small shovel.

Parents of teen drivers

New drivers are more likely to have minor breakdowns and less likely to know what to do. A single tool with clear functions, plus a talk about roadside safety, can give both of you peace of mind. Make sure they know how to call for roadside help and where the tool is.

As a gift

Car emergency tools are a practical gift for new drivers and older relatives. Pair it with a quick demonstration and a note about where to keep it in the car.

• Drivers who want a compact, rechargeable roadside kit in one device
• New drivers and teenagers getting their first car
• People in areas prone to storms, floods and power cuts who want a crank-powered light and phone top-up

Who should skip it

• Owners of cars with laminated side windows who are buying it mainly to escape through a window
• Anyone who needs a jump starter, tyre inflator or real power bank; the Kelvin 8 is none of these
• Drivers who already carry a spring-loaded escape tool, a good torch and a power bank
• Buyers who want strong independent owner reviews before trusting a safety tool

How much does the Kelvin 8 cost, and what's in the box?

The Kelvin 8 costs $49.95 on the offer page on 4 October 2026, three for $119.90 and five for $179.85, while Kelvin's own store listed it at $53.99. In the box you get the tool, a USB charging cable, an instructions guide and a carry case. It combines a seatbelt cutter, window breaker, flashlight, magnetic red strobe, 100 dB siren, 2,000 mAh power bank and hand crank.

The Kelvin 8 comes in orange, black or camouflage on Kelvin's own store; the offer page photos show orange. Each comes with a USB cable, guide and carry case.

Specifications

Kelvin 8 price and bundles

On 4 October 2026 the Kelvin 8 offer page (opens Kelvin in a new tab) listed:

The three-pack is marked most popular. One per car is the sensible number.

Kelvin's own store

Kelvin's store data, registered in Mississauga, Ontario, listed the Kelvin 8 at $53.99 in black, camouflage and orange, against a compare-at price of $59.99. It also lists the Kelvin 17, 23 and 36 multi-tools and other products.

What this means for you: the offer page was $4 cheaper for one Kelvin 8 on the day we checked. Compare shipping before ordering.

Is it good value?

Separate items would cost more in total: a spring-loaded escape tool, a good torch, a small power bank and a hand-crank light. But each separate item is usually better at its own job. The Kelvin 8's value is convenience and having everything in one place.

Cost compared with a full roadside kit

A complete basic roadside kit, including warning triangles, a reflective vest, a first aid kit, jumper cables or a jump starter, a torch, gloves and a blanket, costs more than the Kelvin 8 but covers far more situations. The Kelvin 8 fills the lighting, signalling, escape and phone-power slots in that kit. Think of it as one part of your car's emergency preparation rather than the whole thing.

Who makes it

Kelvin Tools is a Canadian company known for compact multi-tools. The Kelvin 17 page credits founder Kevin Royes, who pitched on Dragons' Den. The Kelvin 8 page credits "Neil and Dave" for creating the Kelvin range, and says the business is operated in Toronto; Kelvin's store lists Mississauga, in the Greater Toronto Area. The page does not say where the Kelvin 8 is made. Our Kelvin 17 review covers the brand's best-known everyday multi-tool.

A note on the page itself

The offer page's browser title describes the Kelvin 8 as an "ultimate solution for cleaner, fresher air", which has nothing to do with an emergency tool and looks like text left over from another product's template. It is a small detail, but together with the reused testimonial it suggests the page was assembled quickly, so we leaned on the FAQ and Kelvin's store for facts.

How well does the Kelvin 8 work?

The Kelvin 8 should cover roadside basics well: a flashlight, a magnetic strobe and a siren for signalling, plus a seatbelt cutter and a breaker for tempered side and rear windows. Its limits matter. Like every escape tool, it cannot break laminated glass, which all windscreens and many newer side windows use. The 2,000 mAh power bank gives a partial phone top-up, and cranking adds only minutes of talk time.

Nobody on our team has used the Kelvin 8, so this section is based on the page, the FAQ, independent testing of escape tools generally and how each function typically performs.

Breaking windows: tempered vs laminated glass

Car glass comes in two types. Tempered glass is treated to shatter into small, blunt pieces when struck at a point; it is used in many side and rear windows. Laminated glass is two layers of glass bonded to a plastic layer; it cracks but stays in one piece. Windscreens are always laminated, and many newer cars use laminated side windows to reduce ejection in crashes and improve security and quietness.

AAA's 2019 testing of vehicle escape tools found that most tools broke tempered side windows, but none could break laminated glass, and that about one in three 2018 models had laminated side windows. AAA also found spring-loaded tools broke tempered glass more reliably than hammer-style tools.

The Kelvin 8's breaker appears to be a hammer-style tip on the end of the body. The FAQ says it is lab-proven to break car windows, but it does not mention laminated glass.

What this means for you: check your car's side window markings. If they say laminated, plan a different escape route, such as a rear window that is tempered, and practise the plan.

Cutting seatbelts

Recessed blades are a reliable design for cutting seatbelts. The FAQ says the blade slices through jammed belts. Keep the tool within reach while belted in, or it cannot help.

The flashlight

LED flashlights are bright and efficient. The page does not give a brightness figure or run time. For changing a tyre or finding something in the dark, a moderate handheld light is enough. If you want a separate handheld light as well, our TacticalX flashlight review explains what a budget zoom flashlight on AAA batteries really delivers.

The strobe and magnets

A red flashing light stuck to the car helps other drivers see you. Magnets only stick to steel panels; aluminium and plastic panels will not hold it. Warning triangles placed well behind the car remain the standard advice in many places.

Roadside safety basics

When you break down, the device is only part of staying safe. Commonly given advice includes:

• Pull as far off the road as you safely can, onto the shoulder, verge or a lay-by away from moving traffic.
• Turn on hazard lights and, at night, sidelights.
• If it is safe, get everyone out of the car on the side away from traffic and wait behind a barrier.
• Use warning triangles where they are legal and safe to place.
• Call roadside assistance or emergency services and give your exact location.

The Kelvin 8's light and strobe make several of these steps easier in the dark.

The power bank and crank

A 2,000 mAh battery can add a meaningful top-up to a phone, but not a full charge on most modern phones. The hand crank is a backup for when everything is flat. The FAQ's own figure, 3 to 8 minutes of talk time for 3 minutes of cranking, is honest and shows the limits: enough for an emergency call, not for hours of use.

Storing it in a car

Lithium batteries dislike extreme heat and cold. Cars can get very hot in summer and freezing in winter. The page does not give an operating or storage temperature range. Check the guide, keep the tool out of direct sun, and recharge it every few months.

Water and weather

The page does not give a water resistance rating. A tool used at the roadside in rain, or near floodwater, should cope with splashes, but avoid submerging it. If it gets wet, dry it before charging.

Durability of the crank and hinges

Fold-out cranks and hinged parts are the weak points of multi-function devices. Crank gently, avoid forcing the handle, and keep the device in its pouch to protect moving parts from damage in a cluttered car.

What owners say about using it

The page shows two testimonials. One, from "Linda", praises having every tool to hand, "even a hammer"; the same words appear word for word on Kelvin's Kelvin 17 offer page. The other says only that it will come in handy. We found no independent owner reviews.

What the missing reviews mean

A safety tool is something you hope never to use, so many owners will never test the window breaker or seatbelt cutter for real. That makes owner reviews less informative than for everyday products, and independent testing more important. AAA's testing of escape tools in general is the best guide to what to expect from any window breaker.

Are the Kelvin 8's claims true?

The Kelvin 8's functions are real, but its rescue claims go too far. "The life-saving multi-tool every car needs" and help in "virtually any outdoor emergency" overstate what a compact tool can do. "Lab-proven to break car windows" names no lab, standard or results, and no tool breaks laminated glass. "Never without power" depends on a small 2,000 mAh battery and a slow hand crank.

"The life-saving multi-tool every car needs"

Overstated. It can help in some emergencies; it cannot guarantee rescue, and it cannot break laminated glass.

"Lab-proven to break car windows and cut seatbelts"

No lab, test standard or results are named. Tempered glass, yes; laminated glass, no tool can.

"Rescuing you from virtually any outdoor emergency"

Overstated. It covers lighting, signalling, a little power and vehicle escape from tempered windows.

"Never without power when you need it"

Partly true: the crank provides a little power. The battery is small.

"No batteries required"

True in the sense that it is rechargeable. It still has a lithium battery that ages.

"25,000+ units sold" and "as seen on" logos

Unverified.

Claims scorecard

Is the Kelvin 8 better than a spring-loaded escape tool or a jump starter?

The Kelvin 8 puts many basics in one device, but specialist tools beat it at single jobs. Small spring-loaded escape tools were the most reliable on tempered glass in AAA's testing, cost little and clip within reach. A portable jump starter can start a car with a flat battery and usually has a larger power bank and torch. For everyday breakdowns, many drivers would benefit more from a jump starter.

Kelvin 8 vs a spring-loaded escape tool

Small spring-loaded tools, often on a keychain or clipped to a visor, were the most reliable on tempered glass in AAA's testing. They cost little and are easy to keep within reach. If escape is your main concern, a spring-loaded tool plus a separate light may serve you better.

Kelvin 8 vs a jump starter

Portable jump starters can start a car with a flat battery and usually include a large power bank and torch. They do not cut seatbelts or break windows. Many drivers would benefit more from a jump starter for everyday breakdowns.

Kelvin 8 vs a home emergency radio

Hand-crank emergency radios with lights and phone charging are common for storms and power cuts. They add weather radio, which the Kelvin 8 lacks.

Is the Kelvin 8 legit, and what should you check before buying?

The Kelvin 8 comes from Kelvin, an established Canadian tool brand, with a 90-day money-back guarantee, though we found no Trustpilot profile or independent tests and the page shows only two testimonials. Before buying, check whether your side windows are laminated, because escape tools cannot break laminated glass. Plan to keep it within reach while belted in, and recharge it every few months.

Check your windows

Laminated side windows cannot be broken with escape tools.

What to do: look for markings in the corner of each side window; many carmakers mark laminated glass with the word "laminated" or a similar symbol. Ask your dealer or check the owner's manual if unsure.

Keep it within reach

A tool you cannot reach is useless.

What to do: store it in the centre console or a door pocket, not the boot or a locked glovebox, and make sure it cannot fly around in a crash.

Keep it charged

A flat battery means no light, siren or strobe until you crank.

What to do: charge it every few months and after use, and check it before long trips.

Heat and cold

Car interiors reach extremes.

What to do: keep it out of direct sunlight and check the guide for temperature limits.

Know the escape order

In a submerged vehicle, safety organisations commonly advise: seatbelt off, window open or broken, children out first, then get out. Do not wait for the car to fill.

What to do: talk through the plan with your family, and practise unbuckling and reaching the tool.

Lithium batteries and airlines

If you travel with the Kelvin 8, power banks generally must go in carry-on bags, not checked luggage, and the seatbelt blade and window breaker may raise questions at security.

What to do: check your airline's rules for power banks and tools before flying, or leave it at home.

Fleet and work vehicles

Some employers require specific safety equipment in work vehicles.

What to do: check what your employer or local law requires, as the Kelvin 8 may not meet a specific requirement such as warning triangles or a certified first aid kit.

How to buy the Kelvin 8 the smart way

1. Check whether your side windows are tempered or laminated, then order from the Kelvin 8 order page (opens Kelvin in a new tab).
2. Buy one per car; the three-pack is marked most popular.
3. Note the 90-day guarantee and keep the packaging.
4. Charge it fully and test every function at home.
5. Store it within the driver's reach and tell passengers where it is.

The Kelvin 8 scores 5.1 out of 10: claim accuracy 0.8, build durability 1.1, price competitiveness 1.3, usability 1.3 and owner satisfaction 0.6, each out of 2. Owner evidence is thin. The page shows just two testimonials, one copied word for word from Kelvin's Kelvin 17 page, and we found no Trustpilot profile or independent test of the Kelvin 8 on 4 October 2026.

Reviews on the page

The page shows two testimonials. One praises having every tool, including "a hammer"; the same text appears word for word on Kelvin's Kelvin 17 page. The other is a one-line comment.

Independent reviews

We found no Trustpilot profile or independent tests of the Kelvin 8 on 4 October 2026. Kelvin's other multi-tools have a longer retail history.

What we would test with the Kelvin 8 in hand

If we test it ourselves, we will try the breaker on tempered and laminated glass samples, cut seatbelt webbing, measure light output and run time, check how much charge the power bank and crank deliver, and test the magnets on steel and aluminium panels. We will update this review with the results.

How we scored the Kelvin 8

Every score on the site follows the five criteria on our how we test page.

The score would rise with honest guidance on laminated glass, published light and battery figures, and independent owner reviews.

What we did, and did not, do

We read the offer page and FAQ, Kelvin's store data and AAA's escape tool testing, all on 4 October 2026. Nobody on our team has used the Kelvin 8, and no figures here come from our own testing.

How to use the Kelvin 8 for the best results

Charge the Kelvin 8 fully with the USB cable, then test the flashlight modes, SOS, strobe and siren at home and try the crank for a minute. Store it within the driver's reach, such as the centre console or a door pocket. In a breakdown, switch on hazard lights, then use the strobe. To break a tempered window, aim for a lower corner and turn your face away.

1. Charge it fully with the USB cable when it arrives.
2. Test the flashlight modes, SOS, strobe and siren at home.
3. Try the crank for a minute to learn how it feels.
4. Store it in the car within the driver's reach.
5. In a breakdown, switch on hazard lights, then use the strobe and flashlight.
6. In an emergency escape, cut the belt, then break a tempered side window at a corner.
7. Recharge it after any use and every few months.

Breaking a tempered window

Aim for a lower corner of the window rather than the centre, where glass flexes more. Turn your face away, and clear glass from the frame before climbing out.

Practising without breaking anything

You cannot practise breaking a window, but you can practise the steps: reaching the tool while belted in, finding the blade by touch, and moving it to the window corner. Do this a few times so it becomes automatic. Show passengers too.

Cutting a seatbelt

Hook the recessed blade over the belt and pull it across in one firm motion. Cut the shoulder belt first, then the lap belt if needed. Keep fingers away from the slot.

Using the strobe

Turn it on before leaving the car, so you are visible while you walk to the back of the vehicle. Stick it to a steel panel at the back of the car where following traffic will see it. Use warning triangles too if you have them.

Charging a phone

Plug in early, while the phone still has charge, rather than waiting until it is dead. Keep calls short in an emergency.

Saving your phone's battery in an emergency

Turn on low-power mode, lower screen brightness, close apps you do not need, and send texts rather than long calls where possible. Text messages often get through when calls struggle on weak signal. Share your location with one person and then keep the phone for calls.

After an emergency

Once you are safe, recharge the Kelvin 8, check the blade and breaker tip for damage, and replace anything used, such as warning triangles or first aid supplies. If the tool helped, put it back within reach before your next drive, not in a bag in the boot.

Checking it twice a year

A simple, easy-to-remember twice-yearly habit is to check the Kelvin 8 when the clocks change: charge it, test each light mode and the siren, crank it for a minute, and make sure it is still within reach of the driver's seat with the seatbelt on.

Using the light at home

During a power cut, the flashlight and crank give light without batteries. Keep it in a known place at home during storm season, then return it to the car.

Troubleshooting

What else do people ask about car emergency tools?

Most questions are about window breakers and where to keep them. On tempered glass most breakers work, with spring-loaded tools the most reliable in AAA's testing, but none break laminated glass. Look for markings in the corner of each window or ask your dealer to find out which glass you have. Keep any escape tool within reach while belted in, not in the boot or a closed glovebox.

Do car window breakers really work?

On tempered glass, most do, with spring-loaded tools the most reliable in AAA's testing. None break laminated glass.

How do I know if my car windows are laminated?

Look for markings in the corner of the glass or ask your dealer. Many newer cars have laminated front side windows.

Where should I keep an escape tool?

Within reach while belted in: the console, door pocket or a visor clip.

What should be in a car emergency kit?

A common checklist includes a phone charger or power bank, torch, warning triangles, reflective vest, first aid kit, blanket, water, snacks, gloves, jumper cables or a jump starter, a tyre inflator or sealant, an escape tool within reach, and seasonal items such as a scraper and shovel in winter.

Should I keep the Kelvin 8 in the glovebox?

The page suggests the glovebox, but escape tools should be reachable while belted in. A glovebox may be hard to reach or open after a crash. A door pocket or centre console is better for the escape functions; the glovebox is fine if you mainly want the light and power bank.

Is a hand-crank charger useful?

As a last resort, yes. It gives a few minutes of talk time per few minutes of cranking.

Can the Kelvin 8 jump-start a car?

No. It has no jump-start function.

Is the Kelvin 8 good for power cuts at home?

Its flashlight and crank help, but a dedicated lantern and power bank last much longer.

Do I need more than one?

One per car is enough. A second for the home emergency kit can make sense.

Will the magnets damage my car's paint?

Magnets can scratch paint if grit is trapped underneath or if the device slides. Wipe the panel and the magnets before attaching, and lift it off rather than sliding it.

Is the siren loud enough to be heard?

At 100 dB close up, the siren is loud, but sound drops with distance and traffic noise. It helps attract attention from nearby people, not from far away. The SOS light is often more noticeable at night.

What is the difference between the Kelvin 8 and the Kelvin 17?

The Kelvin 8 is a car emergency tool with escape, lighting, signalling and power functions. The Kelvin 17 is a household multi-tool with a screwdriver, bits, hammer face, tape and level. They do different jobs; our separate review covers the Kelvin 17.

Is a spring-loaded tool better than the Kelvin 8's breaker?

For tempered glass, AAA's testing found spring-loaded tools more reliable than hammer-style tools, partly because they need little swing in a cramped or flooded car. If escape is your priority, a spring-loaded tool on your keys or visor is a cheap addition.

Can children use the Kelvin 8?

The light and siren are simple enough for older children to use in an emergency. The seatbelt cutter and window breaker should be explained carefully, and the tool kept out of reach of young children, who might hurt themselves with the blade or crank.

Does the Kelvin 8 come with instructions?

Yes. The FAQ says it comes with an instructions guide. Read it once when the tool arrives, and keep it in the pouch.

Will it work after years in the car?

The battery slowly ages, especially in heat. Test it every few months, and replace it if the light dims quickly or it no longer holds charge. The crank should still work as a backup.

What colour should I choose?

Kelvin's store lists orange, black and camouflage. Orange is easiest to find in a dark car or at the roadside; black and camouflage are more discreet. For an emergency tool, visibility usually wins.

Can I use the Kelvin 8 as an everyday torch?

Yes. Using it regularly is a good way to make sure it works, as long as you recharge it and return it to the car.

How long does the Kelvin 8 hold its charge in the car?

The page does not say. Lithium batteries slowly lose charge, faster in heat. Check and top it up every few months, and before long trips.

Is the Kelvin 8 worth it?

If you have no roadside kit and want one rechargeable device for lighting, signalling, a phone top-up and basic escape, it is a reasonable choice at the offer page's $49.95. If your side windows are laminated, do not rely on it for escape, and consider a jump starter or separate tools for better performance.
