Your laptop, your tablet computer, your phone or some pair of wireless headphones need to be charged through USB. Everything gets plugged in, though some of the smaller devices have charging interfaces that double for data ports. The manufacturer was kind enough to give you a wall-outlet dongle that converts the 110 volts coming out of your wall outlet into 5 volts of USB power.
- Input voltage: AC 100 to 125V 50/60Hz
- Output voltage: USB: DC 5.0V 2100mA (2.1 amps)
- Operation temperature: 0 to 35 Degrees Celsius (32 to 95 Degrees Fahrenheit)
- Guaranteed to charge all mobile phones that accept USB power, including iPhone 4
2 USB ports in the wall plate next to the 110 volt sockets, and you’ve doubled the versatility of your power line. We just happened to get a hold of a handful of these outlets.
Note that you need to use your considerable brains to install these outlets. Please learn everything you can about replacing wall outlets before even thinking about performing this kind of electrical work. Electricity is dangerous, and you could electrocute yourself, set the house on fire, or ruin your sensitive electronics if you do something wrong. This is available in thinkgeek.com.
