Charge two devices at the same time A built-in Apple 30-pin connector is ready to directly charge your iPod or iPhone, an extra female USB output is designed to ensure its compatibility with most devices via the original charging cable. This means you can charge two of your mobile devices at the same, or you can always choose to use the original cable of your mobile device to charge instead of using the built-in connector.
Convenient to use The built-in male USB input dock provides the convenience of recharging by simply connecting it to any powered USB equipment. No bulk cables are needed for charging and re-charging.
Battery level indicator and re-charging status indicator A simple press on the on/off button on top will tell you how much juice is left in the Power Tube: red means below 15%, orange means 15%-40%, green means 40-70% and blue means 70% up. The same indicator lights also function as re-charging status indicator. When the blue LED light remains on (stops blinking), it means the Power Tube is fully re-charged.
