Compact 20000mAh Power Bank for Daily Carry

The Monoprice 44370 stores 20000mAh in a palm-sized case that can deliver four to six full phone charges. Three output ports let you power a phone, tablet and headphones at the same time. A built-in digital LED display shows the exact remaining capacity at a glance. It ships with a USB-A to USB-C cable for immediate use.

PD 3.0 20W and QC 3.0 22.5W Fast Charging

The single specification that decides fit is the maximum output of 20W over USB Power Delivery 3.0 and 22.5W over Qualcomm Quick Charge 3.0. Phones supporting either standard can move from empty to roughly sixty percent in under thirty minutes. If your device needs higher wattage or a different protocol this bank will not charge it at its peak speed.

Low Heat and Silent Operation

Normal use produces minimal warmth because the circuitry runs well within its thermal limits at 20W and 22.5W loads. No fans are present so operation is completely silent. Power draw from the wall matches the rated outputs plus typical conversion loss, so a standard 5V or 9V charger refills the bank efficiently.

They enable up to 20W over USB-C Power Delivery and up to 22.5W over Qualcomm Quick Charge, so compatible phones can reach about 60% in 30 minutes.
