Portable Lithium Jump Starter 4000A Peak Car Starter (All Gas, up to 10.0L Diesel Engine) 12V Car Battery Booster Pack, Power Bank with USB Quick Charge and Type C Port

Brilliant bit of kit. Comes in a really neat and tidy case easy to take around. Used a lot so far and not had any trouble no sparking when connecting and really easy to use. Incredible power for such a small device, has started tractors over and over before needing re charging. Definitely easier than jump leads would be lost without one now.

Amazing piece of kit, used many times so far to start plant on cold mornings. started the telehander no probs. Charged when bought and still on full power 1 month later. Found it on an Autotrader review site. Highly recommended, good carry case and lightweight and a decent price.

Writing a review after using this for over a year and recommending to someone else. Used frequently over the past year to jump start my Audi 3.2 petrol and always jumps it first time even on a completely dead battery. Case is great for keeping all the stuff together. Does take a while to charge but understandable for the size but does output enough power to charge devices like laptops etc albeit not as a super fast charger but good in a pinch.

Todate perfect. Still going strong. Very neat & compact

Right, I’m going to try and answer what’s likely to be your first question: yes, it has enough grunt to start a dead battery, in cold, snowy conditions. In fact, this thing was better at starting my dead battery than jump leads attached to a mates car. I tried another brand on Amazon (who shall remain unshamed) and sent it back. The crap the supplier fed me was that the car battery needed to have a certain voltage for it to work. I put a tester on it. It had 8 volts. Needless to say I sent it back and got this one. Car fired, straight out the box. Simple to use, no buttons to press. It detects what your doing and delivers the charge. As with all of these, you can use the cars alternator to charge it back up, via the cigarette socket, or usb. It’s only downfall is the torch, but that’s not what you’re buying it for. I tried it on a car that’s been sitting since the outbreak of covid. Fired up, without zero effort, as if the car was parked the day before. This thing will get you out of trouble. Just don’t keep it in the boot, if you have an electronic latch!!

Used loads, brilliant as always, use it for charging my laptop on the go aswell, its great would buy another one

Used it in anger twice on a 1.4l and a 2.0 litre petrol and it works OK. Holds it's charge well enough after left in boot for a month. Be interesting to see how it works with a diesel when the winter really bites. Nice little case and attachments. Keeping it all safe in the boot. 4000 amps mmm! I'll take that with a pinch of salt. Maybe for 1 microsecond!

This is the best product I have ever come across will boost a dead battery on anything easy to use has a light which activates when you push the button has two usb ports to charge your phone or give power to very strong does what it says on the boxwotlrth every penny comes with a case so you can store it for protection and also when connected will indicate if you have connected it the wrong way if all light are green press button and you have all the power you need compact and easy to carry
