Sounds like he wants a power supply like the Socket Mobile plug supplies--the round push in connector that is close to the mini USB plug on the Vertica/AVier--that would leave the mini USB open.

Don't know what size the socket moblie connector is, and the Avier/Vertica V2 doesn't come with a wall charger and a round 5V plug for the little hole that looks like it receives one. But is that a headphone jack and not a power supply jack? The Avier and Vertica V2 are the same device.

I went with the cigarette lighter option for 7 bucks...
