No matter how efficient the software gets, the battery life on portable gadgets still needs improvement. But until science delivers, we're stuck with external chargers like the Padacs Ultracharge Mini.
Essentially a miniature version of the 12,000mAh Ultracharge, the mini features a 5400mAh 2A battery that can be used to charge everything from your iDevice, smartphone, games console or digital camera. It features two USB ports for concurrently charging two different gadgets, and weighs just 168 grams.
Also included in the box is a 1.2 metre USB extension cable and a 10-in-1 multiconnector with ports for pretty much every type of phone.
For $50, it seems like a pretty solid device for battery life peace of mind...
