I have two separate kits, an KR808D (Nebula) kit and a KGO 1100mah kit, both with AC adapters for their USB chargers. The adapters look the same, are they basically the same? I'm asking because while I would use the USBs for each type (have to anyway) it would help a lot if I didn't have to keep changing the adapter in the outlet itself all the time, but could use the same AC adapter for both USB style chargers. I don't want to damage either of them though.
