I love the peace of mind travelling with this Battery Jump Starter. It not only has the power to jump start the car (only tested it out to twice in one charge so far, but still had plenty of charge) but it can also charge 3 devices simultaneously, I had it charging my iphone, wireless headphones and a action camera all at the same time on a recent trip and it is great. I am able to charge up the jump starter with my quick charger power brick and supplied USB-C to USB cable in under 2 hours to completely full and then it is an absolute work horse and great peace of mind. The device has a power indicator led light up section showing how much charge is left, a torch function which is good in the dark when looking under the bonnet (but not very bright), voltage display on the jump starter cable adapter plug and shows the voltage reading! I intentionally tested out the crossed wires alarm (I hope this doesn't void the warranty) by crossing the Positive and Negative clamps (a big no no for batteries) and the devices safety kicked in to protect the battery and played an audible beep alarm, it was not very loud but a good fail safe if you cross them by mistake or lend it to a mate who has no clue. The only thing that could make this product better is a nifty case that keeps all the bits together for easy storage in the boot. I've been using the box, but it is not a long term solution. Overall this is a fantastic purchase and great peace of mind for long road trips and periods away from civilisation. Highly recommend!
