Wireless charging technology had a slow start with various rival technologies competing.
With the advent of Apple recently selecting the Qi (pronounced “chee”) for its iPhones it is expected to accelerate the roll-out of wireless charging.
Qi is similar to how a wireless electric toothbrush recharges.
Initially only 2,5 Watt charging were allowed for a relatively slow charge but now 5 Watt and even 10 Watt systems are comparable to wired charges.
Wireless charging is set to take over from wired charging with efficiencies of up 85% already commonplace.
