JumpsPower GTR 4000A jump starter & powerbank for 12V/24V vehicles
If you need a proper bit of kit for those “just my luck” moments, the JumpsPower GTR 4000A Jump Starter is absolutely spot-on. Built for both 12V and 24V motors, this portable powerhouse is a lifesaver for everything from family cars and motorbikes to heavy-duty trucks, vans, and even boats. With a thumping 4000A peak current under its belt, it’ll fire up dead batteries in seconds – and you can do that up to 60 times on one charge. Not too shabby, eh?
The GTR’s clever third-gen battery tech means it’s more than ready for modern motors, including hybrids, turbos, and stop-start engines that can often leave lesser jump starters scratching their heads. You can also top up your gadgets thanks to the built-in fast-charging USB-C output, so charging your phone or even a MacBook on the go is a doddle. Forgot your cable? It’ll still rapid-charge your iPhone from flat to half-full in half an hour (just grab a USB-C to Lightning lead).
It’s not just about getting you moving, though – the 12V DC output lets you run all sorts of handy kit, like tyre inflators or a portable hoover, right off the powerbank. Plus, the built-in LED torch isn’t just for finding dropped fivers under the seat – it’s got work and emergency modes, including a bright amber warning light that’ll help keep you safe if you’re stranded at night.
Safety-wise, it’s belt and braces. With 14 protection features, including reverse polarity and spark-proof tech, you won’t need to worry about frying your electrics or yourself. It’s tough too, built to handle proper British weather from -20℃ up to 60℃, so you can chuck it in the boot and forget about it until you really need it.
- You can jump start everything from a hatchback to a lorry, wherever you are – no need to wait for roadside rescue.
- Charges your gadgets on the move, so you’ll never be caught with a flat phone or laptop at the worst time.
- Handy for camping, work sites or anywhere you need portable 12V power for tools or inflators.
- Super robust and ready for the British climate – just keep it charged and you’re sorted.
- Packed with safety features, so even if you’re not a mechanic, you can use it with confidence.
