Mac and iOS peripheral maker Moshi has announced the IonBank 10K, its first portable battery for charging tablets and cellphones. The device costs $110 and is available directly from Moshi's web site.
The IonBank has two USB ports and outputs 18 watts, making it suitable for everything from an iPod or iPhone to a full-sized iPad. As the name implies, the integrated lithium-polymer batteries hold 10,000 mAh of charge. A button and five-LED gauge show you how much charge is left in the battery, and an integrated USB cable is used to power up the battery when it's not in use.
Both ports can be used simultaneously, but Moshi vaunts the IonBank's "dynamic power sharing" circuitry, which detects the type of device connected and adjusts its charge rate accordingly. If one port isn't in use, all power output will be directed to the other port. A carrying pouch is included.
Moshi plans other IonBank products - smaller-capacity IonBank 5K Lightning and Micro USB versions, which are physically smaller and use integrated cables so you can leave your charging cable behind. Those are planend for release later this fall.
