Description
High-Capacity Portable Charger
The UGREEN PB312 20000mAh is a three-port battery pack rated at 74 Wh for phones, tablets and travel routers. A USB-C port carries 20 W of bidirectional power delivery, while two USB-A ports deliver up to 22.5 W each. The integrated digital display shows the remaining charge as a percentage.
Two 10000 mAh cells form the bank at 3.7 V nominal. Rated output reaches 12500 mAh at 5 V/3 A. The USB-C port negotiates 5 V/3 A, 9 V/2.22 A and 12 V/1.67 A. USB-A output steps through 5 V/3 A, 9 V/2 A, 10 V/2.25 A and 12 V/1.5 A. Supported protocols include PD3.0, PD2.0, QC3.0, QC2.0, AFC and FCP.
A 20 W PD charger refills the pack in about six hours. Pass-through charging runs at 15 W while the bank tops up. With three devices attached, total output settles at 5 V/3 A. The flame-resistant PC shell carries UL certification, and the cells meet IEC 62133.

User documentation
Why Choose the PB312
The 74 Wh rating sits under the 100 Wh cabin limit for carry-on luggage.

PD and QC negotiation matches most enterprise notebooks and handsets.
The percentage display removes guesswork before a site visit.
Grace Nyambura (verified owner) –
I was looking for something reliable for my small business, and this fits the bill. It keeps my phone and POS device running during power cuts. The two-way charging is convenient. Would recommend.
James Mwenda (verified owner) –
Does exactly what it says. 20000mAh is more than enough for a full day out. I like that it can charge two devices at once without slowing down much.
Njeri Kamau (verified owner) –
Solid power bank. It charged my phone from zero to full in about an hour and a half, which is impressive for a bank this size. Delivery was quick too, ordered on Monday and received on Wednesday.
David Mutua (verified owner) –
I bought this for my wife who travels a lot for work. She says it charges her phone and tablet without issues. The build quality is good, the ports feel sturdy. Good value for the capacity.
Achieng Odhiambo (verified owner) –
Compact enough to fit in my pocket. Charges fast and holds charge well.
Kevin Mwangi (verified owner) –
Used it on a three-day trip to Kisumu and it kept both my phone and earbuds charged. The only reason I am not giving five stars is that it takes a while to fully recharge the bank itself, even with fast charging. Otherwise solid.
Mercy Wanjiku (verified owner) –
Great capacity for the size. I carry it in my bag daily and it has not let me down. The 20W output charges my phone noticeably faster than a standard charger.
Brian Ochieng (verified owner) –
This power bank has been a lifesaver during the recent outages. It charges my phone three times over before needing a recharge, and the two-way fast charging means the bank itself tops up quickly when I plug it in. Build feels solid, not flimsy.
