With Anker‘s latest Astro3 external battery, you can charge up to three devices simultaneously. The 12,000mAh battery has plenty of power to keep Android, iOS, or any other USB-chargeable devices going no matter how long your day is. Anker says the Astro3 is a “versatile external battery pack with three USB ports including a Smart Port that identifies the type of device that is plugged in and then adjusts to deliver its fastest charge speed. The second generation Astro3 is the first to feature a single port that can offer full-speed, fast charges to both iPad and the Samsung Galaxy Tab.” The other two ports can charge smart phone quickly, too, as it has a total output of 5V/4A. It’s available now in black from Amazon for $49.99.
