I purchased this charger to replace a LG STA-U34WDI charger for my daughter's Sprint LG Rumor Touch cell phone. Her dog had chewed and destroyed the plug and cable.This replacement arrived and I find that it is meant to replace a LG STA-P52WS charger which uses a wider micro-usb plug than the LG STA-U34WDI charger.Also, both the original LG STA-P52WS and the STA-U34WDI chargers have an output of 700 milliamperes. This inferior replacement only has a rated output of 350 milliamperes.That's half the output of the original chargers!Avoid this inferior unit and look elsewhere.
