Took over 5h to charge. 1 full charge of an iphone X = 50% of the charge. Seems to be quite useless. Hope it was a defectuous item. If the re-ordered one does the same - will certainly return for reimbursement.

So far not a success. After fully charging the unit & first use: my phone was still at 50% after a few hours & not using at all but over 6 hours later was down to only 1%. Unit still shows 4 LED lights indicating optimum use range

Dear Customer It is really easy to identify the problem, If you have no issue at all while charging your phone with the same cable on another power adapter, then this power bank is very likely defective. If this is the case, please don't hesitate to contact our customer service and we will arrange a replacement for you. If it can be fixed by switching cable, then is must be the cable you are using goes bad. Best Regard
