Capacity and charging speed

This 20000mAh lithium-polymer power bank delivers up to 35W output through USB-C ports that support PD 3.0 and QC 4.0. It suits travellers and commuters who need multiple top-ups for phones, tablets or small accessories between wall outlets.

Sustained output behaviour

The unit can charge an iPhone 16 from 0 to 61% or a S22 ultra from 0 to 40.9% in 30 minutes. Four simultaneous outputs share the total current, so peak speed drops when several devices draw power at once. Recharging the bank itself takes about 3 hours via the bidirectional USB-C port.

Installation and common issues

A USB-C to USB-C cable is included; plug it into any port and press the button to begin. Double-tap the button to enable trickle-charge mode for low-draw devices such as earbuds or smartwatches. The digital display shows remaining capacity. The 392g weight and 13.7 x 7.0 x 2.63 in dimensions may feel bulky in a small pocket.

Questions about this item

Does the 35W output make the power bank get hot during long charging sessions?

The unit includes overheat protection alongside over-charge, over-voltage, over-current and short-circuit safeguards, so it manages temperature automatically while delivering up to 35W.

What cable do I need to recharge the power bank itself at full speed?

A USB-C to USB-C cable is included in the box and both Type-C ports support bi-directional fast charging, letting the bank refill in about 3 hours.

Can I still use the trickle-charge mode for my older Bluetooth headset while the bank powers a phone from the other ports?

Yes, double-tap the power button to activate trickle mode — shown by a looping LED — and the remaining two USB-A and one Type-C ports can charge other devices at the same time.
