With a power bank like Aukey’s 20000mAh Dual-USB Power Bank, keeping your devices charged while traveling becomes easier. With its dual USB ports, while at home or on-the-go, you will be able to power two devices simultaneously up to 3.4A. While it usually sells for just under $35, today, when you enter ZXSOA5UX promo code during checkout, you can score one on sale at Amazon for just $26.85. That $7 discount is the best in nearly a year to reach this charger.

Aukey’s PB-N36 Portable Power Bank features a capacity of 20000mAh that can fully charge tablets such as the 12.9-inch iPad Pro almost one-and-a-half times before charging again, while phones such as the Samsung Galaxy Note 9 and the iPhone XS can be charged multiple times before this charger needs more power. Its AiPower USB ports provide optimized charging per device, while built-in safeguards protect them from excessive current, overheating, and overload. Aukey even includes a 2-year purchase warranty and a micro-USB cable.

This power bank ships at Amazon for free, even though with Amazon Prime you would receive your order even faster. You can start a free 30-day trial to score free two-day shipping, exclusive members-only discounts, and more if you’re not already a member.
