Bought LG optimus V phone 3 ys ago .. got a rocketfish rf-mcb55 charger with it. Never used it. Am trying the charger now in two different cars but not working. Red light on end of charger is on, but phone is not charging, not responding.
Nigel's "not compatible" response was erroneous: att z221 in fact does have a micro usb port, and I checked the charger at the store before taking it home. My concern was whether the electrical output was correct or whether 1000 mA was too high. Kindly respond. Al.
The AT&T Z221 has a mini USB input, and as such will be incompatible with this micro USB car charger. You would need a charger with a mini USB attachment, such as this model: http://bit.ly/13q8YpN
When I plug the internal charger, the red light no longer comes on. If the circuitry is still good, I'd rather not throw it into the landfill. How can I check and, if necessary, change the fuse?
