Don't have enough spare juice to charge all your iThings? The Exovolt Plus is a stackable battery pack with unlimited expandable capacity, according to maker Exogear.
The charger consists of a main 5,200 mAh lithium polymer battery and sub batteries that you can pile underneath it to create a battery stack. Each unit is 3.7 inches square and weighs about 5.5 ounces.
It comes with 30-pin and micro-USB connectors and can charge Apple iPhones, iPads, and iPods, as well as most smartphones and tabs.
The four LED lights on the units show how much power remains. An Auto-Safety Protection System ensures your tower won't overheat.
The main battery will sell for $89.95 and the sub batteries for $49.95. Unfortunately, they're sold separately.
If you don't mind the extra weight and do fancy playing Jenga with batteries, you won't have to wait too long. The Exogear site says the Exovolt Plus is "coming soon."
