The EP800 is an original device of Sony Ericsson, which is delivered for example with the SE Xperia Neo V. It has a charging current of 850mA at a voltage of 5V.
The supplied cable exceeded but then my expectation: It is 140cm long! These are all 80cm more than my previous charger! The manufacturer of this cable is, as well as the AC adapter, Sony Ericsson. So original cable with original power adapter - and for the price! A very strong buy recommendation, without limitation!
