Tzumi PocketJuice 20000 mAh Portable Charger

This Tzumi PocketJuice is a 20000 mAh portable charger designed to keep USB‑enabled devices powered while away from a wall outlet. It suits anyone who needs reliable backup power for phones, tablets or other gadgets during travel, commutes or long days out.

Two Quick Charge 3.0 ports

The unit provides two Quick Charge 3.0 USB ports plus QuickChip technology, so two devices can charge at once and the LCD shows the exact remaining percentage. Buyers who need wireless charging, a USB‑C Power Delivery port or a smaller capacity for lighter carry should consider other options.

20000 mAh capacity with dual‑port output

The 20000 mAh cell delivers multiple full phone charges and can top up a tablet alongside a handset. Heavy users charging several large devices daily will eventually drain the bank and need access to mains power to replenish it.

Questions about this item

What cables do I need to connect my phone to the two Quick Charge 3.0 USB ports?

You need a USB cable that matches your phone's charging port — USB-C, Lightning or Micro-USB — to plug into either of the two Quick Charge 3.0 USB ports.

Will the 20000 mAh battery charge an older phone that only draws 5 W?

Yes, the power bank negotiates the correct voltage and current, so an older 5 W phone charges normally from either USB port.

How do I confirm the power bank is delivering Quick Charge 3.0 speeds after I plug in?

The LCD percentage display shows the remaining capacity and updates rapidly when a Quick Charge 3.0 device is drawing high current.
