To whom may be concerned, this is my second time have this exact kind of portable charger, the last one cut off and stopped charging for some reason but before then I found it to be perfect and the best one yet. It lasts for so many charges before having to charge that I can’t even tell you how many. It also doesn’t take long for it to charge back up like the smaller ones do.
