Sorry about the multiple messages, I snuck away for only a few minutes, so I need to make this quick... I am using the charger that came with my regular ego kit. It is a usb with a house plug attached. I always have plugged it into the electrical outlet... That past says: Power Supply model 510-013-016-pcc Input AC 100-240v 50/60Hz 100mA Output: DC 5.0V = 500mA. The USB (ego connector) says: Input DC 5V 500mA Output: DC 4.2V420mA.
When I first got my 5 volt pass through, I tried using it, but it wouldn't work. Works fine when plugged directly into the computer... Then, the first vv ego clone just went dead in my hands, while I was walking around with it. It had been charged maybe 5 times or so... I sent it back and the vendor replaced it for me, but when I try it, it is shutting off after about 2 seconds. I charged it, even though it did seem to come almost fully charged (has battery indicator bars). Sometimes it will last a little longer before it shuts off completely... grrrr.... Thanks!
