This fiesty little powerhouse boasts the ability to charge most smart phones six or seven times before being plugged in again, with an energy efficiency rate at a whopping 10% above most other external batteries on the market today.
There are three ports on the Astro3, so you can charge more than one device at a time. There’s a single smart port (5V / 2.4A max) for maximum charging speed on any device (including iPads and tablets), and the other two will charge Android smart phones at full speed. A simple shake will tell you how much power remains in the Astro3 and how soon you should seek to recharge it.
Astro3 Means Freedom for You and Freedom for Me
Really, if you want something faster and more efficient than the Astro3, you’re going to have to high-tail it down to Tosche Station and pick up whatever power converters happen to be in stock there; mind the Sand People on the way, though. For your time and money, online ordering is your most efficient — and least potentially deadly — option.
