But this one I can't seem to find anything similar to online. My problem is that it will charge using the wall adapter and stock cable, it will charge using the same cable plugged into my laptop. It will even charge using the same cable plugged into one of my many other wall adapters. it will NOT charge off of a portable power bank. I've even tried it on multiple other power banks (friends/family units) with the same result, won't charge. this is becoming very frustrating. I've cleaned the port with air/alcohol, I took the phone apart looking for damage with the intention to solder but couldn't see any visible problems with the solder joints. anyone have any thoughts on wtf to do next?
