Amazon offers 2-Pack Miady 10000mAh Dual USB Power Bank for $22 with a direct discount. That makes one power bank at just $11 only.
Two 10000mAh battery packs not only for portable charging but also around your home. Allowing you to charge mobile devices without having to be connected 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.
This platform also consists of two USB output plugs that identified all the available equipment and supplied effectively the up to 5 V 2.1A current output. 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.
