Amazon is currently offering a 2-Pack Miady 10000mAh power bank for $22 for a limited time. The offer saves you 15 percent off the regular selling cost today.

Two 10000mAh battery packs not only for portable charging but also around the house. You can charge mobile devices without tying to a plug socket. They all charge 2.4 times for the iPhone X, 3.6 times for the iPhone 8, and 2.2 times for the Samsung Galaxy S9.

Each of them has 2 USB output ports that detect all connected devices and efficiently distribute the current output up to 5V 2.1A. The battery itself can be fully refilled in 5 hours at 5V 2.0A with the USB C and Micro USB ports.

The charger is much more secure than any Li-ion charger, thanks to the Li-polymer battery pack. It’s also lighter and slimmer, so you can carry it around easily, even on airplanes.

For a 10000mAh power bank, weighing just 218g and only 14mm thick, it feels incredibly compact. The design of Grippy is simple to hold, easy to throw into a bag, and incredibly portable.
