External battery packs become more and more affordable by the day. As one of the big names in the scene, Anker keeps pushing the envelope to provide better storage and features to make your life easier. With the Astro E4, they’re making 13,000mAh of power small enough to fit in your pocket. But a battery is only as good as it’s ability to charge dependably. How do the reviews stack up? Let’s take a look.
At just 4.9 inches tall, 3 inches wide and 0.9inches thick, the battery pack isn’t much larger than many smartphones. Weighing just over a half a pound, you can toss it in your pocket or bag and barely notice a difference. Reviewers loved the design, though some noted accidently pressing the power button on occasion.
Numerous reviewers tested the batteries capabilities and found an astounding 92-percent efficiency. This means less time and energy wasted transferring power. To help you keep tabs on the power level of the battery pack, Anker placed four LEDs on the front of the pack. These represent 25-percent charge intervals making it easy to check power levels at a glance.
The charger includes a carry case, multiple adapter tips and a retractable charge cord for convenient charging on the go. You can recharge it from empty in as little as eight hours using a 2A wall adapter, making it perfect for overnight charging for use throughout the day. It also includes a flashlight for those outdoor excursions or finding something in your bag on a dark train or flight.
The pack has two USB ports--One for Apple and one for Android--with output up to 3A to accommodate tablets and other high-drain devices. Features include automatic shut off when your connected device is done charging and Anker’s PowerIQ technology. Anker claims this senses the optimal power level to charge your phone or tablet and speeds up charging times. Reviewers all agreed that it made a major difference.
Overall, reviews of the Anker E4 are positive. Massive storage, sleek design and affordable pricing make it a leader in the battery pack market. Battery Pack Reviews calls it, “A game changer in the industry of battery packs.”
