Review on BANDC PJH-RS-0123 Power Outlet: Dual USB Charger Socket 2.1A & 1A for iPad, iPhone, Car, Boat, Marine, Mobile by Timothy Harper

I don't know about the durability of this item yet, but with a USB meter the output voltage is just over 5 volts. For those worried about the blue LED draining the battery, I grabbed a drill and a blue LED frame. Once removed, you can insert a small screwdriver further into the device to break the farther away LED bulb. Even if the LED bulb is broken, the device will charge normally, so they are not on the same circuit.
