This one lives in the center console. It plugs into the 12V socket to charge your phone, but it’s also a power bank, a flashlight, a glass breaker, a seat belt cutter, and a signal light all in one. The glass breaker is built into the positive pole of the charger itself — you’d never know it was there. Pretty clever for something that’s just sitting there charging your phone on any given Tuesday.

  • 1400mAh power bank — portable backup charging, good for roughly two full phone charges
  • Hidden glass breaker — built into the positive pole, aimed at window corners where glass is weakest
  • Seat belt cutter — one swipe cuts through a jammed belt
  • 120-lumen adjustable-neck flashlight — plus a red flashing signal light
  • Glow-in-the-dark band — easy to locate the USB port at night

Eight Things, One Device, Always in the Car

The 8-N-1 does something most multi-tools don’t quite pull off: it’s actually useful every single day, not just in emergencies. It charges your phone through the 12V socket. It charges itself so the power bank is ready when you need it. That’s enough reason to have it plugged in all the time — and that means the glass breaker and seat belt cutter are always there too.

The glass breaker is tucked into the positive pole of the charger itself. You’d have no idea it was there. But if you ever need to break a window to get out — or get someone else out — you aim for the corner of the glass, where it’s weakest, and swing. One strike is usually all it takes.

Who This Auto Safety Tool Is For

Anyone who spends time in a car. That sounds obvious, but think about it — most people have nothing in their vehicle that could help them if they ended up in water, upside down, or unable to get a door open. The 8-N-1 handles those scenarios quietly, from the cup holder.

Road trippers and commuters who just want a reliable USB charger will appreciate the power bank. Parents with kids in the car will appreciate having a seat belt cutter that doesn’t require hunting through a glove box. The red signal light is handy if you’re ever broken down on the side of the road at night.

It’s also a reasonable gift for a new driver, a college kid heading off in their first car, or anyone who travels a lot. The kind of thing you hand someone and say, “just keep it plugged in.”

Is This the Right Choice for You?

Choose the 8-N-1 Auto Safety Tool if you want:

  • Emergency tools that are already in the car without any extra effort
  • A USB charger that doubles as a glass breaker and seat belt cutter
  • A portable power bank for when you’re away from the outlet
  • A low-profile tool that doesn’t look like an emergency device

Consider something else if you need:

  • A heavy-duty jump starter or larger power bank for multiple devices
  • A standalone multi-tool with a wider range of mechanical functions

How Each Function Actually Works

The USB car charger plugs into any standard 12V DC receptacle and charges phones or tablets directly. While it’s plugged in, it’s also topping off the 1400mAh internal battery — so the power bank is always charged. The glow-in-the-dark band around the USB port makes it easy to find in the dark without turning on a light, which is a small thing that turns out to be genuinely useful.

The 120-lumen flashlight has an adjustable neck, so you can angle it wherever you need it. There’s also a red flashing mode for visibility if you’re broken down on the side of the road. The seat belt cutter is built to work in one clean motion — no sawing, just pull. And the glass breaker, hidden in the positive pole, is designed to break tempered glass at the corners, which is where automotive glass is most vulnerable.

Practical Details

The 8-N-1 measures 5 13/16″ x 1 1/8″ and weighs 0.45 lbs. It plugs into any 12V DC car socket and includes a USB cable. The 1400mAh power bank is charged via the car socket while plugged in. Flashlight runs off the internal battery. Safety Technology backs it with their standard warranty.

Everything on this list — charger, power bank, glass breaker, belt cutter, flashlight — is already in the car just because you plugged it in. Hard to argue with that logic.

Frequently Asked Questions

How do I use the glass breaker in an emergency?

The glass breaker is built into the positive pole at the top of the charger. To use it, unplug it from the socket, grip the unit firmly, and strike the corner of a car window — not the center. Automotive tempered glass is most vulnerable at the edges and corners. One solid strike is typically enough to shatter the window. It’s worth knowing this before you ever need it, so take a look at where the glass breaker is located when you first get the unit.

How many times can the power bank charge my phone?

The internal 1400mAh battery will charge most modern smartphones roughly once to twice depending on your phone’s battery size. Older or smaller phones will get closer to two charges; newer flagship phones with large batteries may get one full charge. It’s not a replacement for a dedicated high-capacity power bank, but it’s more than enough for an emergency situation when you need to make a call.

Does the flashlight work when the unit is unplugged from the car?

Yes. The flashlight draws from the internal 1400mAh power bank, not the car’s power. So even if you’re outside the vehicle, you can use the flashlight and the red signal light independently. The adjustable neck lets you angle it wherever you need it, which is handy if you’re changing a tire or looking under a hood at night.

Can this stay plugged in all the time without draining my car battery?

The unit draws minimal standby power when plugged in. In most vehicles with a 12V socket that stays live when the car is off, it’s worth unplugging it to avoid a slow drain on your car battery over several days. If your 12V socket only works when the ignition is on, this isn’t a concern at all. Check your vehicle’s manual if you’re not sure which type you have.
