The Nexus charging orb is based on the Qi inductive charging standard which allows your device to be powered without the need of wires. All you need to do is place your Nexus 4 on the orb and it recharges.
The orb release comes in time of LG and Google finally working out the supply issues with the Nexus 4. Even though the device is widely available the shipping times are at a couple of weeks, but this should get better over time.
Are you purchasing a charging orb for your Google Nexus 4? Or do you prefer the traditional charging method?
