This Intocircuit travel charger works fine with my Google Nexus tablet and my wife's LG Cosmos Touch, but it is not compatible with my LG G2. The specs say it has a 6 ft cable but the cable on mine is about 4 1/2 feet. I don't understand why it comes with a ferrite bead on the cable since the cable is carrying dc current, unless the engineers are not confident in the ac to dc filtering. I am not set up to verify its multiple circuit protections specs (over-current, short-circuit and over-temperature) or to run it from 220V (for international travel), but those are important features which I am glad are included in this device.
