GOOLOO GP4000 4000A Peak Jump Starter for All Gas & 10L Diesel

I bought the yellow jump starter three and a half years ago, and the reason I’m only writing my review now is that I wanted to see how well it performed over time. First of all, the quality is excellent, and in terms of performance, it really does work brilliantly. I bought this jump starter because my previous one had stopped working, mainly because I had not recharged it for about four months. However, with this one, even after I forgot to recharge it for almost a year, not only did it still work perfectly, but the battery level had not even dropped by one bar. It can also be used as a very powerful power bank, and the built-in torch gives off a very good and acceptable amount of light. Overall, I’m very pleased with it and would definitely recommend it.

Such a great item, used several times and helped other motorists out with it. It is so powerful and easy to use.

Had one for 3 years just ordered another on offer , great for starting a van but also great for charging phones while away usually about 4/5 charges on my iPhone . Worth the money

Purchased this due to car battery giving up. After purchasing, followed instructions, charged GooLoo then again, followed instructions, connected to car battery, DIESEL car started at the turn of the key! GooLoo was then placed in boot of car. A few days later, a lady was unable to start her DIESEL vehicle in a supermarket carpark, fortunately GooLoo came to her rescue. The lady couldn't thank me enough and wanted the GooLoo details for her to purchase one. Thank you GooLoo, you saved two AA call-outs in less than one week. I highly recommend this item and especially the specifications on what vehicles it can be used on.

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.

Used for the first time the other day it worked flawlessly great quality too

Excellent bit of bit. Great value. Have used multiple times already, (low & dead batteries on mid sized diesel engines) and only had to recharge a couple of times. Great power from a small unit you can take whenever you need.

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.
