Customers are saying

Customers love the Power Bank (20,000mAh, 30W PD w/ built in USB-C Cable) for its fast charging speed, portability, and great battery life. Many appreciate its overall performance and the convenience of the integrated USB-C cable.

    Great budget power bank. Having both USB type A and C and the built-in USB type C makes it convenient.

    This power brick is great! Used it heavily for some time now on recent trips and it was able to keep several phones charged at the same time. No complaints :)

    We purchased two of these charges to take on a week long rafting trip through the Grand Canyon. They were easy to pack and we had more than enough power. These will get a lot of use everywhere we go.

    To charge it to a 100% takes a while and when you use it the battery drains fast. It does however charge things quickly. Good enough.
