Anker 2nd Generation Astro E4 13,000mAh External Battery Review

Anker has consistently shown that smartphone and tablet accessories don’t have to be expensive in order to deliver quality. Case in point, the Anker 2nd Generation Astro E4 13,000mAh External Battery. It has an MSRP of $89.99 but, when purchased through our Amazon Affiliate Store it is under $30! That’s an amazing deal!

Inside the package you get the battery itself, a USB to microUSB charging cable and a protective bag. Considering the fact that this is a budget battery the inclusion of the bag is a nice touch.

Slimmer, sleeker, smarter – enjoy the world’s most powerful portable battery more than ever before.

The revamped E4 rests nicely in your palm and sports a single button perfectly positioned for your thumb.

The design of the Anker 2nd Generation Astro E4 13,000mAh External Battery is simple. There is a single button that turns the battery on and off and lets you check the remaining charge by activating up to four small LED lights. Pressing and holding the button for three seconds turns the onboard flashlight on and off.

On one end of the Anker 2nd Generation Astro E4 13,000mAh External Battery, you will find the aforementioned LED flashlight. Two USB ports flank the LED. These aren’t just any USB ports. No, these USB ports are smart… very smart. As Anker explains:

Not all charging ports are created equal. Standard ports only communicate effectively with particular devices, like Apple OR Android, often limiting their recharge rate. But with PowerIQ™ technology, each port intelligently identifies your device to speak its unique charging language. So plug in any brand or model and enjoy compatibility that doesn’t limit your charging speed.
