I asked the following question yesterday in the Aerco thread that's been going on, but it kinda got lost in subsequent conversation.
If I put rechargeables into the Aerco, is the only option to get a charger and recharge the batteries externally or can I get a same-voltage (as the batteries) wallwart with a connector the size of the Aerco jack and recharge them without ever taking the cover off the Aerco?
