rgisler1 year ago000Hello Community, what kind of charger are you using? It says min. 0.35 A, max. 0.7A charging current, so a maximum of twice as much is possible. I have a USB charger, 5V/0.5A, that should work, right?Show in original language (German)Philipp_931 year ago • purchased this product000purchased this product Helpful answerI use an old power supply unit from the iphone, which I got for free back then, and the battery charges without any problemsShow in original language (German)CommentAnonymous1 year ago • purchased this product000purchased this productYes, that should work...
