Number 3. Otterbox Fast Charge
In the medium-capacity range, a power bank that can charge multiple devices or larger devices than a phone is a practical choice. The Otterbox Fast Charge power bank boasts a 15,000mAh capacity and proved to be almost as effective as the 20,000mAh units, with a price tag that is approximately $30 cheaper. Over the course of the testing period, this power bank was the most frequently used one to recharge my devices. It has a sleek exterior design with a faux leather finish in gray and copper accents. The power bank is slightly larger than a deck of cards, weighs just over 11 ounces, and is an attractive accessory that feels sturdy.
This power bank recharged two smartphones twice and provided an extra third of a charge for each. When the iPad was added to the mix, it charged it fully and provided an additional third of a charge. The Otterbox power bank also retained most of its charge while not in use, which means it should have plenty of power when you need it if you carry it around with you.
The Anker 535 Power Core slightly outperformed the Otterbox power bank in this category, but its price is higher. However, if you’re looking for a power bank that can deliver a fast charge to your Galaxy phone, the 535 is the way to go. It charged the Galaxy three times, each time taking approximately an hour to get to 100 percent. It had enough leftover power to charge the phone by an additional nine percent before shutting down. While the power bank did become warm, it never felt excessively hot. The 535’s cool iridescent finish was also a nice touch.
