Its 2,500 A peak current gives it enough muscle to crank massive gas or diesel engines, and its USB-C fast-charging makes it a dual-purpose power bank that’s essential for both emergency and everyday use.

💡Description
💡Description
The 4250a Powerbank / Jump Starter is a premium, 12-volt lithium jump box designed for extreme performance. Built into a rugged, IP65-rated housing, this unit packs a 74 Wh battery that delivers 2,500 amps of peak current, enabling it to jump-start gas engines up to 8.5 L and diesel engines up to 6.5 L.
It features advanced UltraSafe 2.0 protection — spark-proof clamps, reverse polarity detection, and enhanced thermal regulation — making it one of the safest jump starters you can own. Plus, it’s not just for jump-starting: its 60 W USB-C port supports power delivery both in and out, letting you use it as a high-output power bank for your laptop, phone, or tablet.
On top of that, the built-in 400-lumen LED flashlight offers multiple modes including high beam, SOS, and strobe — perfect for roadside emergencies. The GBX75 recharges quickly (full in ~1.7 hours), or in as little as 5 minutes for one jump-start.

What Our Customers Say
-
Great little jump starter now that I found a recharging solution.
This is an excellent little jump starter. It really works well, is light weight and small and has plenty of power to quickly jump start any car, no matter how dead. The only thing it didn't like was that if I leave it unplugged, the battery drains and I found it half charged every time I needed it

Top Rated Vehicle Jump Starter
One of my best purchase!

Absolutely Awesome!
Its a small (compact) unit which has a multi-function light. Also, it has a USB port to charge accessories like a cell phone. I bought this model to support a full sized diesel pickup, which requires more amps. Highly recommended and necessary for emergency equipment.
-
Powerful and Effortless. Robust Wiring, great clamps.
I feel like this could probably start a large diesel truck or tractor, and is a nice piece of kit to carry around in case somebody needs help. And it's nice to be able to help, without tearing my battery covers off and scraping up my own terminals. Databyter

Can Jump Start a Truck With No Battery Connected!
This is great because sometimes you may not be able to get a battery replaced immediately or fix a parasitic drain from a vehicle short. In this scenario I could continue driving as normal and recharge the jumper as needed.
