NEVER BE POWERLESS WITH THE 24-HOUR POWER SYSTEM. The 24-Hour Power System is everything you need to charge (or power) at home or on the go in the palm of your hand.
The Powermat for 2 devices offers a home base to wirelessly charge two Duracell Powermat-enabled devices-your iPhone 4/4S (using the included Wireless Case) as well as our Portable Backup Battery. The Portable Backup Battery provides on-the-go power to double the battery life of any iPhone, iPod, and most micro-USB-enabled smartphone devices.
To use, simply set the Portable Backup Battery and/or enabled device on the Powermat to start charging. The bleep lets you know that your device is connected and charging. When it€s fully charged, take the Portable Backup Battery to power up on the go. Phone sold separately. Also available in white.
PMA is the standard for smart and environmental wireless power backed by AT&T, Starbucks, P&G, Powermat and dozens of global leaders, and deployed at leading venues including in select Delta Air Terminals and Delta Sky Clubs, Westfield Malls, at Madison Square Garden, Barclays Center and in Jay-Z's 40/40 Club.
