well the OEM ac adapter that came with my Droid Maxx is: Part #: SPN5797A Input: 100-240V 50/60hz 0.2a Output: 5.0V 1150mA I have in my posession a Motorola SPN5689A Input: 100-240V 50/60hz 0.2a Output: 5.1V 750mA and a Samsung Galaxy Nexus OEM 100-240V 50/60HZ 0.15A OUTPUT: 5.0V 1.0A anyone know what specs are a concern for mismatching? like can I use the one with 0.15a input when the original is 0.2a input? is the 5.1v output vs 5.0v output a concern? i want to take great care of my fat maxx battery. and i want more ac adapters, plus will need one for the ebay qi charging base i'm buying. would like to buy them at $10 or less shipped.
