Description
Portable 74Wh Power Delivery Bank
The Ugreen PB312 power bank pairs a 20,000mAh lithium-ion battery with 20W USB-C Power Delivery input and output. It charges phones, tablets, earbuds and smartwatches through three ports. A digital LED screen shows remaining capacity.
The USB-C port supports 5V/3A, 9V/2.22A and 12V/1.67A, reaching 20W. Two USB-A outputs cover 5V/3A, 9V/2A, 10V/2.25A and 12V/1.5A, delivering up to 22.5W per port. Total output across three connected devices caps at 15W.

Kevin Omondi (verified owner) –
Charged my phone three times over a weekend trip to Kisumu and still had bars left. The 20W two-way charging means I can top it up quickly from a wall adapter too. Solid build, no rattling.
Tabitha Wangari (verified owner) –
The 20000mAh capacity gets me through a full day of field work with two devices. It’s a bit heavy in the bag but that’s expected at this size. Fast charging works properly with my Samsung.
Allan Kipchumba (verified owner) –
Delivery was quick and the unit came sealed. I’ve used it for about a month now — the USB-C port handles both input and output, which keeps the cable count down. Charging my phone from 10% to full takes roughly an hour, which is what I expected from 20W. It gets slightly warm under load but nothing alarming.
Rehema Njoki (verified owner) –
Good capacity for the road. Does the job well and I like that it can charge two devices at once.
