Customer Reviews Summary

The product was delivered with proper instructions and all the requisite attachments. The pack was also well over half-charged when it was delivered. It is nice and compact in size, so hardly take up any storage room in the car. The instructions were easy to understand, and the charger itself is very easy to assemble and use. It also comes with a handy drawstring storage bag to keep everything together. It is USB charged so I can plug it in to charge in the car or take indoors and charge like my mobile phone - all nice and easy.My car battery was fairly new, but I haven't used the car that much over the festive period and then there was a sudden, nasty drop in temperature so the battery had drained out and the engine wouldn't turn at all. But this charger worked like an absolute dream! I used it after a quick top up of the power pack (just to make sure) and the car turned over immediately - no problem at all. Fantastic! It was quite a relief - brilliant!I live in the middle of the country and my nearest garage is nearly 6 miles off, so professional help is not close by. Having this charger means I'm no longer reliant on jump leads and the kindness of others if this happens again. So all in all, the charger is well worth the price. It's now essential kit in the car - it gives me a lot of peace of mind.
