Duracell myGrid USB charger costs $35
Duracell has introduced a new myGrid USB Charger that is compatible with the company's own myGrid wireless charging pad. The charger uses a lithium-ion rechargeable battery that recharges the batteries of other devices such as cellphones, e-readers and tablets through a USB port. Cellphone batteries are said to be boosted by up to four hours, while an e-reader's life can be extended by up to 100 hours.
The myGrid charger itself can be charged over its USB input or Duracell's charging mat. The device is now available for $35.
