Review: Great and Useful Gadget - 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.
Review: Recommended buy! - Great device that is well worth the money. So far jumped an Audi a3 2 litre an a 1.4 Hyundai i20 that had flat batteries. It started them straight away without missing a beat and no struggling like you sometimes get with jumper cables on another car. The pack charged quite quick and came in the box with half battery. Box included the jumper cables module, usb charger without plug, and a carry bag. It’s about the size of a portable phone charger a bit larger than an iPhone pro max. It’s light weight and built very well. After starting the 2 cars it’s still at full battery so can see it lasting a while so gives peace of mind if you keep it in the car. Well worth the price and definitely more affordable than the other brands on the market charging double or triple the price. As it’s a power pack looks like you can also charge your phone from it using usb A as an output and also has an inbuilt small light. Highly recommend. I bought based on the other positive reviews and happy with the purchase

### ⭐⭐⭐⭐⭐ Price and size, excellent product.
*by M***K on 12 February 2026*

I bought one of these a while ago, for my work van as it stood around at times, but never had it with me when I needed to jump start another vehicle, a large battery on a Land Rover, so for quickness I ordered another one, wasn't expecting to much, gave it a full charge, vehicle wouldn't turn over, put the jump pack on, it starts to flash and tick, gave it a few seconds, turned the ignition and it started first time. It's a heavy vehicle, large engine, but these little jump pack managed a good few times until I managed to change the battery. It's got a bright light, it's a USB charger as well, an excellent little bit of kit, I've got 2, and would recommend it to anyone, for the price, and the size, absolutely fantastic.
