Satechi has announced the Portable Energy Station. The US$49.99, 10,000 mAh battery pack features a 1-amp and a 2-amp USB port to keep most smartphones or tablets fully charged — including charging a dead iPhone 4S up to five times. 

The battery pack features a lightweight (5.93 ounces) and compact (5.5 inches long) design and sports a rechargeable lithium ion battery. Additional features include a battery life indicator and auto off feature which detects when the connected device is fully charged.  

The Portable Energy Station comes complete with a USB charging cord and six connectors compatible with most smartphones and tablets. It’s available at Satechi.net and Amazon.com.
