Battery life is much better than what it once was, but it could always be improved. Until devices can run for days without requiring a charge, external battery packs will have a demand. Anker, the company that produces some of the strongest external battery packs, has three models available at a discount through Amazon. The sizes range from 13000mAh to 20800mAh. Even that smallest capacity is able to charge some of today’s smartphones four times. The largest is enough to at least charge a phone and a tablet twice each. And, unlike many other external battery packs, Anker’s have multiple ports for simultaneous charging.
