The Power Bank 20000mAh Portable Charger 22.5W is designed to provide a fast, high-capacity, and multiple device quick charging solution for users in the UK. Its 20000mAh capacity and 22.5W output make it possible to charge rapidly a smartphone, a tablet, or any other small device, thus making it the right choice for a long journey or for heavy daily usage. Its robust body and the various ports guarantee safe accessibility to power when in high demand.

Design and Build

This power bank, which is about 6.2 x 2.9 x 1.0 inches in size and weighs around 400g, is characterized by materials such as ABS, and PC that show quality and robustness. For UK travellers who are device-heavy, the digital LCD display comes in quite handy as it allows accurate monitoring of the power in the bank. The process of the power bank is such that it basically will resist both scratches and fingerprints due to its texture, and even though it is a little bit bigger, it is still easy to carry in a backpack or travel bag. There are two USB-A and one USB-C ports where you can plug in your devices and recharge them in whichever way you want.

There are two USB-A ports (22.5W) and one USB-C port (20W) for the purpose of connecting and charging a series of devices at the same time. It is compatible with most smartphones, tablets, and USB-C devices, so it's easy to understand that it is the perfect match for a high power user in the UK.

I like the compact and portable size of this charger with a huge 20000mAh battery. The quick charging 22W supports super speeds that charge my phone within a short period, and it can charge several devices simultaneously. A must have port charger in our daily use.
