I modified some older wallwarts which have a 5vdc output and even 2 amps to work as usb phone chargers. They do charge the phones, but the phone will say slow charging. So I installed an app that shows the charge current, and it comes up 470ma or sometimes less.
I have another real good fast charger of 5vdc and 2 amp output that came with a hotspot. The app reports a charge current of 1200ma.
WHY is it complaining about slow charge if the cruddy charger says it puts out 5vdc and 2 amp power? Does the phone test the charger output and does not someway like it, so throttles the charging?
