Anker, maker of phone accessories and backup batteries, has just announced its most efficient mobile battery to date -- the Astro3. This 12,000mAh battery pack, which Anker calls "flask sized" (4.4 x 3.3 x 1-inches), offers charging for three devices simultaneously over USB. The pack outputs up to 4a in total across the ports, meaning you'll have more than enough juice to power a tablet and two phones if necessary. There is also a circular LED power indicator that shows how much power is left in the pack, which is a nice touch.
Anker says that the Astro3 is the highest efficiency backup battery it has made, with 80-percent efficiency on its capacity offering a quoted 6-7 charges for most modern phones before it has to be recharged itself. For the road warriors among us this would be a great solution. The Astro3 is retailing for $49.99 and can be purchased from Amazon at the source link below.
