Anker 2nd Gen Astro 6400mAh Power Bank

Anker’s new 2nd Generation Astro External Battery may be one of the smartest external batteries that I’ve ever used. It’s PowerIQ USB port recognizes the power requirements of your specific device and sends just the right amount of power at just the right speed for that device. The 6400mAh capacity Astro External Battery 

The candy bar-sized Astro external battery is perfect for life on the go as it is compact and comes with a handy carrying pouch, which holds both the external battery itself and the included USB to microUSB cable. The sleek-looking Astro will fit in a purse, pocket, or any travel bag so it’s also great for traveling.

Anker’s PowerIQ technology is really neat in that it automatically adapts it’s charging protocol depending on the device that it’s charging. Some devices like to be charged slower, some like to be charged faster. Some devices want more power at once, while others want less. PowerIQ knows this and will deliver the precise amount of power at the precise speed that your device needs. This ends up saving almost 2.5 hours while charging an iPhone 5s as compared to charging it using an everyday laptop USB port. This is really smart way to charge your device.

Everything included with the Astro.

Another reason that this device is so smart is that it will actually tell you, in 10% increments, how much battery life is left in the LG battery cells that lay inside the Anker Astro. This is in stark contrast to most other external batteries that only read the battery capacity in 25% or 33% increments. This helps you ensure that you squeeze the most out of your battery before recharging it. The Anker Astro has an LED ring installed just underneath the external skin, which shines through beautifully. There are 10 LEDs inside the ring that each represents 10% of the battery life.
