Our verdict
React earns its socket. As a charger you'll use it daily; as an emergency kit it puts a cutter, breaker, flashlight and beacon exactly where your hand can find them in the worst sixty seconds of a drive. For thirty dollars, it's the rare safety purchase that isn't dead weight the other 364 days.
The short version
Emergency tools only help if they're in reach when things go wrong — not buried in the trunk. React by ChargeHub solves that by living in the one spot you can always find: your car's 12V socket. Day to day it's a USB charger and rechargeable power bank; in an emergency it pulls out to become a flashlight, a red flashing beacon, a seatbelt cutter, and a spring-loaded window breaker. Seven tools, one plug, zero digging.
Pros & cons
Pros
- Always in reach — it lives in your 12V socket, not the trunk
- Charges your phone daily and holds a reserve as a power bank
- Spring-loaded steel tip breaks a side window in an emergency
- Built-in seatbelt cutter slices a jammed belt in seconds
- LED flashlight plus red flashing beacon for roadside visibility
- Recharges itself while plugged in — nothing to remember
Cons
- Occupies your 12V socket full-time
- Battery reserve is for emergencies, not multiple full charges
- Window breaker works on tempered side glass, not windshields
How it works
Plug it in and forget it
React sits in your cigarette-lighter socket, charging your phone over USB and topping up its own internal battery as you drive.
Grab it when it matters
Break down at night — pull React out for a flashlight, a red SOS beacon, and stored power for your phone.
Cut and break to get out
The built-in blade cuts a jammed seatbelt and the spring-loaded steel tip shatters a side window so you can exit fast.
Who it's for
- Every driver who wants an escape tool actually within reach
- Parents outfitting a new driver's first car
- Commuters and road-trippers who drive at night
- Anyone whose 'emergency kit' is currently buried in the trunk
Why an escape tool in the 12V socket beats one in the trunk
In a crash or submersion, safety experts talk about the first 60 seconds: if a seatbelt jams or doors won't open, the tools that matter are the ones you can grab without unbuckling, climbing over seats, or opening the trunk. That's the entire logic of React — it lives in the 12V socket in your center console, a spot your hand can find in the dark, and it's always charged because the car charges it.
Most drivers already keep a charger in that socket anyway. React just makes that slot do double duty: a USB charger you use every day, wrapped around a seatbelt cutter, window breaker, flashlight and beacon you hopefully never use. The everyday function is what keeps the emergency function within reach.
React vs a standalone escape hammer
A classic escape hammer costs less, but it has two real problems: it needs a mounting spot you'll actually respect (most end up in the glovebox, then migrate), and it does nothing for the far more common roadside problems — a dead phone, no light, no way to be seen. React covers the everyday failures too: it's a charger and power bank first, with a flashlight and red flashing beacon for breakdowns.
The trade-off is glass-breaking technique: a hammer swings with more force, while React's spring-loaded tip is a press-to-fire design that works on tempered side windows with much less room and effort — useful in a crumpled cabin where you can't wind up a swing. Neither will break a laminated windshield; side glass is always the exit.
How to use React's seven functions
Daily: leave it plugged in, run your phone cable from the USB-A port, and let the internal battery keep itself topped up — the LED gauge shows the reserve. On the road at night, the flashlight is one click; the red flashing beacon makes you visible to traffic while you change a tire or wait for help.
In an emergency: pull React from the socket, hook the recessed blade under a jammed seatbelt and pull to cut, then press the steel tip firmly into a corner of a side window until it fires — tempered glass shatters from a corner strike far more easily than from the center. Keep the habit of returning it to the socket, because an escape tool left on a seat slides out of reach exactly when you need it.
Frequently asked questions
What are the 7 functions of the React?
USB phone charger, rechargeable power bank, LED flashlight, red flashing emergency beacon, seatbelt cutter, spring-loaded window breaker, and the 12V plug design that keeps it charged and always in reach. It's an everyday charger wrapped around an escape tool.
Will it break my car window?
The spring-loaded steel tip is designed to shatter tempered side windows with a firm press into the glass — aim for a corner of the window. It won't break laminated windshields, which is true of every escape tool; exit through side glass.
Does it charge my phone like a normal car charger?
Yes — it has a USB output and works as your everyday charger while plugged into the 12V socket, and its internal battery holds a reserve so it can top up a phone even away from the car.
How does it stay charged?
It recharges automatically whenever it's plugged into your car's 12V socket, and an LED battery gauge shows the reserve level. There's nothing to remember or swap.
Where should I keep it?
In the 12V socket — that's the point. It's within arm's reach of the driver's seat, your hand can find it in the dark, and the car keeps it charged. An escape tool in the trunk is an escape tool you don't have.
Does it fit any vehicle?
It plugs into any standard 12V cigarette-lighter socket, which nearly every car, truck and SUV has. If your vehicle only has USB ports, you'd need a 12V socket to use the always-charged feature.
