Energizer will soon release a universal single-zone charger based on the Wireless Power Consortium’s Qi standard. This will include a single-zone inductive charger that can work with the company’s recent iPhone 4 sleeve. A Qi adapter will attach to most phones through mini or micro USB to make it compatible with the Qi standard.
The adapters and sleeves will make most phones ready for Qi. Other WPC members that support the standard include Verizon Wireless, HTC, Nokia, Motorola, and LG to name a few.
Qi Inductive charging standard guarantees that a charger or adapter will talk to another regardless of maker as long as the two meet the needed standards.
