Mascom International stocks the UGREEN PB312 Power Bank at KSh 3,500, pairing a 20000mAh battery with 20W two-way fast charging over USB-C. Each unit is brand new and sealed in UGREEN retail packaging. The UGREEN PB312 Power Bank carries one USB-C port and two USB-A ports, so three devices can draw from it at the same moment. A built-in digital screen shows the battery status, which takes the guesswork out of planning a long day. You can see and test it at our shop in Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD.
Designed for field engineers, NGO field staff, journalists and families on the move, the UGREEN PB312 Power Bank handles the days when no socket is in sight. Think of a survey trip to Turkana, a wedding weekend in Kisii, or a full day of site visits in Industrial Area with a phone running Google Maps. A 10000mAh pack often runs dry by the second evening. With double that stored energy, this model keeps a phone, a hotspot router and earbuds going through two busy days. M-Pesa agents and market vendors also lean on the UGREEN PB312 Power Bank to keep their till phones alive between customers.
Where most Nairobi electronics shops sell heavy no-name bricks with capacity figures nobody can verify, Mascom International carries UGREEN stock with clear ratings and local after-sales support. At Mascom International, we're seeing more buyers choose the UGREEN PB312 Power Bank for upcountry travel, because it covers several phones from one charge. If you only need a single daily top-up in a lighter body, the UGREEN PB311 Power Bank costs KSh 650 less. Walk in to compare the two side by side, or message us on WhatsApp and pay only when your order arrives.
Common Questions About the UGREEN PB312 Power Bank
What is the UGREEN PB312 Power Bank 20000mAh price in Kenya?
The UGREEN PB312 Power Bank sells for KSh 3,500 brand new at Mascom International, Kimathi Street, Nairobi CBD. The price includes the sealed unit, a 6-month warranty on manufacturing defects, and pay-on-arrival delivery across all 47 counties. It sits KSh 650 above the 10000mAh UGREEN PB311 Power Bank, so you pay a modest amount for twice the stored energy. The UGREEN PB502 Power Bank costs KSh 300 more but holds half the capacity with faster 30W output.
UGREEN PB312 Power Bank or UGREEN PB311 Power Bank: which one fits me?
Choose the UGREEN PB312 Power Bank for capacity and the UGREEN PB311 Power Bank for lightness. Both charge at 20W over USB-C, so the speed for a single phone is similar. The UGREEN PB312 Power Bank stores 20000mAh, adds a third port and shows its status on a digital screen. The UGREEN PB311 Power Bank holds 10000mAh in a slimmer body. Daily office commuters do well with the smaller pack, while frequent travellers and parents charging several phones get more from the larger one.
Is the UGREEN PB312 Power Bank worth it for long road trips upcountry?
Yes, the UGREEN PB312 Power Bank is a sound pick for long journeys, since 20000mAh covers several phone refills before it needs a socket. On a Nairobi to Lodwar drive or a two-day trip through the Rift Valley, your phone loses signal and hunts for Safaricom or Airtel Kenya towers, which drains the battery faster. This pack keeps up with that drain. It also helps in lodges and rural homes where sockets are shared or power is cut off at night.
Can the UGREEN PB312 Power Bank charge my phone while it is plugged in itself?
Yes, the UGREEN PB312 Power Bank supports pass-through charging, meaning it refills itself and powers connected devices at the same time. In that mode, output is capped at 15W, so your phone charges at a gentler pace than the usual 20W. This feature is handy overnight: plug the bank into the wall, connect your phone to it, and both are full by morning. You then need only one wall socket, which helps in hostels, offices and shared rooms.
How heavy is the UGREEN PB312 Power Bank to carry every day?
The UGREEN PB312 Power Bank weighs 435 grams and measures 14.7 by 7.16 by 2.77 centimetres. That is heavier and thicker than a typical phone, so it rides better in a backpack, laptop bag or handbag than in a trouser pocket. Boda boda riders and delivery staff often keep it in a jacket pocket with a zip. If you want something that disappears in your pocket, a 10000mAh model such as the UGREEN PB311 Power Bank is the easier carry.
Who should buy the UGREEN PB312 Power Bank, and who should look elsewhere?
The UGREEN PB312 Power Bank fits travellers, field workers, M-Pesa agents and households that charge several phones from one pack. Look elsewhere if you need laptop charging, because 20W cannot keep most notebooks running; the UGREEN PB205 Laptop Power Bank with 145W output handles that. If you mainly want the quickest top-up for a modern phone, the 30W UGREEN PB502 Power Bank suits you better. If cables annoy you, the UGREEN MagFlow Magnetic Wireless Power Bank snaps onto magnetic-backed iPhones.
What does the digital screen on the UGREEN PB312 Power Bank show?
The UGREEN PB312 Power Bank has a built-in digital screen that displays the battery status of the pack. Instead of reading four small lights and guessing, you see the charge level plainly before you leave the house. This helps when you share the bank with family members or colleagues, because everyone can tell how much is left. Customers across Nairobi tell us the screen is the feature they notice first when moving up from an older pack.
Is the UGREEN PB312 Power Bank useful for small business owners in Kenya?
Yes, the UGREEN PB312 Power Bank keeps till phones, card readers and receipt-taking phones powered through a long trading day. Shopkeepers in Gikomba, mama mboga vendors and Lipa na M-Pesa merchants cannot afford a dead phone when a customer is ready to pay. Three ports let you charge a business phone, a personal phone and earbuds from one pack. Its 20000mAh stock of energy usually carries a stall from opening time to closing without a trip to a charging kiosk.
Technical Specifications
Core Function
- 20000mAh battery capacity — enough stored energy for several phone refills, ideal for weekends and trips away from reliable sockets.
- 20W two-way USB-C fast charging — the same port refills the bank and charges phones quickly, so one cable serves both jobs.
- Total rated output of 22.5W — gives phones and small tablets a steady, fast top-up from a single pack, even with two devices connected.
- Pass-through charging up to 15W — the bank charges itself and your phone together, freeing a wall socket in shared rooms.
- Three devices charge at once — a work phone, a personal phone and earbuds can all share the pack on the same trip.
- Brand new and sealed stock — the cell has not been cycled by anyone before you, so its capacity is as UGREEN rated it.
Compatibility
- USB-C port — fits current iPhones from iPhone 15 onward, Samsung Galaxy, Tecno, Infinix, Redmi and most Android phones with a plain USB-C cable.
- Two USB-A ports — older cables, Lightning cables and many budget Android phones plug in without any adapter or converter.
- Fast charging at 20W for iPhone and many Android phones — a low battery climbs back to useful charge in a short break.
- Earbuds, smartwatches, fitness bands and pocket Wi-Fi routers — small devices charge normally and draw only the current they need.
- Tablets charge at a slower, steady pace — useful for a backup top-up on a long journey, though not as quick as a wall charger.
- Not built for laptops — most notebooks need far more than 20W, so a high-output pack suits that work better.
Build
- Weight of 435 grams — sturdy in the hand and best carried in a backpack, laptop bag or handbag rather than a trouser pocket.
- Dimensions of 14.7 by 7.16 by 2.77 centimetres — about phone length but thicker, sized to hold a large cell inside.
- Digital status screen — shows the battery status of the pack clearly, so you plan your day before the charge runs low.
- Three ports along one edge — one USB-C and two USB-A sockets, so cables plug in from the same side without tangling.
- Built to carry the larger cell safely — the casing is sized for 20000mAh, so expect a solid, slightly heavy feel in hand.
- Shown in black in UGREEN product photos — confirm the colour in stock on WhatsApp before you order.
Inclusions
- The UGREEN PB312 Power Bank in sealed UGREEN retail packaging — you break the seal yourself and get an untouched unit.
- Cable bundling varies between shipments — ask our team on WhatsApp what ships in the current box before you order.
- Wall adapter sold separately — any 20W USB-C charger with a Kenyan Type G three-pin plug refills the bank at full speed.
- 6-month Mascom International warranty — manufacturing defects are handled in person at our Kimathi Street service desk in Nairobi CBD.
- Pay-on-arrival delivery — inspect the sealed box first, then pay by cash or M-Pesa once you are satisfied.
Package Contents
The UGREEN PB312 Power Bank ships in its sealed UGREEN retail box with the power bank inside. A wall adapter is not part of the package, and cable bundling can vary between shipments, so check with us on WhatsApp if you need one included. Most buyers already own a USB-C or USB-A cable that works. If you do not, Mascom International sells compatible cables and 20W wall chargers separately and can send them with the same order.

Mascom International backs the UGREEN PB312 Power Bank with a 6-month warranty covering manufacturing defects under normal use. This covers faults such as a battery that stops holding charge, a port that fails or a screen that stops working.
