Used this to start my car, left lights on battery completely flat. Started the car like it was using its own battery. My son also used this while camping charged his phone and camera all weekend used the built light as well. Build quality great. 5 star product.

With extremely cold weather, the 16 year old 4x4 battery was not staying fully charged as short trips were not charging it, so just in case, the jump start was purchased as a safety net. And yes, a poor starter motor turn was boosted when the jump start battery was used. It also charged a smartphone and ipad, so overall, a very useful back up.

The first package delivered to me was “dead on arrival” but the microscopic size and inadequate content of the manual meant it took hours to determine what was wrong and what to do then. A second item was delivered next day that was in good order. After charging (not really necessary) product was excellent with all functions working as specified - brilliant. A telephone support line would have helped.

Lithuim is the future of battery powered tools & equipment. A huge step change. The power bank & jump starter is a brilliant, well designed tool. But I have one criticism - the instruction booklet is printed in such small typeface it''s unreadable - come on - you can do better than that !

Reviews & Awards

Here's a cost-effective gadget that no glove box should be without. In fact, is it more of a car product, a lifestyle item , or a healthy dose of both? It doesn't really matter because we're certain that, for under 50 quid, this thing is awesome...
The bright LED was impressive, even in the sun, and it's functions were usefully repeated on the attractive black module! The connection instructions would keep the user safe. It sailed through our five tests. A great performer, very well priced and with a three year warranty!
