GOOLOO 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.

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.

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.

Can definitely start a small engine. I have 1.8l petrol engine, and it started without battery being connected, this is about as bad situation as it will encounter. Four starts, because first one came in faulty and wasn't charging at all.

Bought and received item the same day - amazing! Was able to jump start my LWB Peugeot Boxer van using the boost option and worked first time. Delighted! Would highly recommend.

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

I’ve had this 2 years and it’s a great starter. It keeps its power and does drain at all. Every vehicle I’ve started with this has taken hardly any power. It’s great value for money. In all the comparison videos I’ve seen it’s came 2nd to the £300 noco which is professional grade

Bought this originally for my 2005 transit van with 2.4 litre diesel engine. Started that absolutely no trouble. I've since used this on other vans and most recently, my little petrol car and it starts first time without fail. Easy to recharge with the supplied USB-C cable - full charge takes several hours but it holds charge well and lasts longer than I've needed it to before recharging again. Comes in a handy protective case to hold it when not in use, and store in your tool shed or back of the car/van. If you're looking for a reliable means to jump start your vehicle, including large diesel engines, this is the one and I fully recommend it.
