The ADATA P20000D Portable Power Bank makes it clear what a flagship power bank is. Packing 20000mAh, this beast is tamed with a high precision digital display that lets you know exactly how much power remains. It also has a bright LED flashlight for added utility and safety. We placed dual USB charging ports on the P20000D so you can top up two devices at once to save time, and bulked it up with robust protective measures. The P20000D embodies ultimate – it’s the envy of all other power banks!
