Quick Charging with the Anker Astro External Battery

With so many chargers and battery packs out there, its not uncommon to ask, “What’s the difference between all of them?” Many a traveler have gotten a cheap charger from the duty-free store, only to find out there isn’t enough time to replenish the battery.

This is an oft-overlooked aspect to chargers that sets Anker apart. Now in its second generation, Anker’s line of Astro chargers are designed to charge phones efficiently and in the fastest time possible.

This is thanks to their exclusive PowerIQ technology. The Astro can identify a device’s maximum possible charge rate and adjust its own discharge rate accordingly. When tested, the product has some of the fastest in-charge and discharge rates around, getting more juice from the plug to your phone with less waiting time.

There are several models available, but the Anker Astro 3 has been cited as one of the best around, with three USB ports, rugged construction, a small size and large storage capacity. It is available for $40 on Amazon, as well as its larger and smaller siblings. Learn more at ianker.com.
