20000mAh 35W Power Bank

The EnergyQC EQ20000 is a 20000mAh portable charger rated for 35W output via PD 3.0 and QC 4.0. It includes built-in Lightning and USB-C cables plus extra USB-C and USB-A ports for up to four devices. A digital LED display shows remaining capacity at a glance.

Travel-ready capacity with built-in cables

Questions about this item

What devices must already support PD 3.0 or QC 4.0 to reach the 35W speed this power bank advertises?

Your phone, tablet or other device needs to support PD 3.0 or QC 4.0 at 30 W or higher; the iPhone 16 and Galaxy S24 are examples that can hit 60 % and 58 % in 30 minutes respectively.

If I keep using an older USB-A cable with the extra USB-A port, what charging speed should I expect?

When multiple ports are used the total output is limited to 5 V / 3 A (15 W shared), so the USB-A port will deliver only standard 15 W speeds.

How can I confirm the power bank is delivering fast charge after I plug in my phone?

The built-in LED digital display shows the remaining battery percentage; a rapid drop in that percentage while your phone’s battery rises quickly confirms 35 W fast charging is active.
