The shipping time was longer than I expected. The problem was the local part, so it's not the product or the seller's fault. Got the item in perfect condition, the box looks excellent. I would expect a better user manual, especially the small size is which can be disturbing. I wanted to check the net for some totorials how to use the tool properly but none showed the starting procedure, everyone has been talking about how the unit should work theoretically. The battery of the starter was 86% and I wanted to see how it performs. We had a Hyundai I40 CW with a1.7L diesel engine here with a totally dead battery, this looked like a good target. I attached all the cables and tried to start the engine... nothing happened just a few clicking noise, like usually from a dead battery. The battery of the starter went from 86% to 55% with two tries. I recharged the starter, it took much time, it stuck at 56% for more than 1 hour. It finally went up to 100 percent in another hour or two. At the second try I wanted to make a better contact with the crocodile clips, so I attached them to a much bigger area on the battery. The car with the same dead battery started at first try. It costed 5% power of the starter. I stopped the engine and waited 10 minutes and tried it again and the starter started the engine at once. I used the starter three times in a row, all successfull starts and the jump starter is at 85% power now. So it works. Will be good for travelling. The power bank part is fine, the lamp is okay, the design is ok. Two things that could be better... the manual, especially its size. And the cable that connects the starter and the crocodile clips... The wire is quite weak and it can get hot in no time. A MUCH thicker cable sould be used, especially when you wanna start much bigger engines. For this money it is a good buy.
