Budi PB812B 20000mAh Mini PD Power Bank is now in stock at Mascom International for KSh 3,500, available at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD. The Budi PB812B holds 20000mAh, rated at 74Wh, inside a body small enough to sit in a jacket pocket or a laptop sleeve. It pushes up to 22.5W through USB-C Power Delivery 3.0 and Quick Charge 3.0, with a front readout showing the exact percentage remaining. Every Budi PB812B sold through Mascom International is brand new and sealed, sourced through authorised distribution rather than the grey-market stock that floods Nairobi's back-street counters.
Matatu commuters on Thika Road, students at Kenyatta University and the University of Nairobi, boda boda riders taking M-Pesa payments from morning to night, and field sales staff moving between Westlands and Industrial Area share one problem: a handset that dies around 4:00 PM. Kenya Power outages make it worse, because a blackout at home means starting the next day at 30 percent. The Budi PB812B answers that with roughly 13,000mAh of usable output at 5V once voltage conversion losses are counted, which covers two to four full refills depending on your handset.
Unlike other electronics retailers in Kenya who stock unbranded 20000mAh units carrying inflated capacity claims, Mascom International sells the Budi PB812B against its published 74Wh rating. Budi has built mobile accessories since 2009 and manufactures under CE, FCC, and RoHS certification. Customers across Nairobi report the Budi PB812B holding its stored charge for weeks between uses, which matters if you keep a backup pack in a bag for emergencies rather than daily top-ups. Walk into our Kimathi Street counter to weigh one in your hand, or order for countrywide pay-on-arrival delivery.
Common Questions About the Budi PB812B 20000mAh Power Bank
How many phone charges does the Budi PB812B actually give?
Expect two to four full refills, not the five or six that unbranded packs advertise. The 20000mAh cell stores 74Wh at 3.7V, but stepping that up to the 5V your phone accepts costs roughly 12 percent in heat and conversion losses. That leaves about 13,000mAh of real output. A 5,000mAh Tecno or Samsung A-series handset takes two and a half charges. A 3,300mAh iPhone takes closer to four. Both figures assume you start from near-empty and stop at 100 percent.
Is 22.5W fast enough for a modern phone?
Yes for most phones sold in Kenya. 22.5W covers Samsung Super Fast Charging on A-series and mid-range S-series handsets, Apple's 20W ceiling for iPhone, and the 18W to 22.5W range that Tecno, Infinix, and Redmi budget models accept. A typical 5,000mAh phone reaches roughly 50 percent in 30 minutes. Phones built for 67W or 120W charging will still charge safely, just at their fallback speed rather than their wall-charger speed.
How long does the Budi PB812B take to refill itself?
Around five to six hours from a 20W USB-C wall adapter. Refilling 74Wh at real-world input rates is slower than charging a phone, so plan an overnight cycle rather than a quick top-up before leaving the house. A 5W phone charger will stretch that past twelve hours, which is why we recommend pairing it with a PD wall plug. Mascom International stocks 20W and 30W USB-C adapters at the Kimathi Street counter.
Can I carry the Budi PB812B on a flight?
Yes. At 74Wh the Budi PB812B sits well under the 100Wh limit that Kenya Civil Aviation Authority rules and IATA guidance set for lithium batteries carried without airline approval. Pack it in your cabin bag, never in checked luggage, since airlines prohibit loose lithium cells in the hold. This matters for anyone flying Nairobi to Mombasa, Kisumu, or Eldoret on a domestic hop where charging points at the gate are scarce.
Does the Budi PB812B work with iPhone, Samsung, Tecno, and Infinix?
It works with any device that charges over USB-C or USB-A, which covers effectively every handset sold in Kenya today. iPhone 15 and newer connect straight to the USB-C port. Samsung, Tecno, Infinix, Redmi, and Oppo handsets do the same. Older iPhones need a Lightning cable into the USB-A port. Wireless earbuds, smartwatches, a Bluetooth speaker, or a portable router running on Safaricom data all charge from the same ports.
Why choose the Budi PB812B over cheaper 20000mAh units in Nairobi?
Capacity honesty is the difference. Many KSh 1,200 to KSh 1,800 packs sold on River Road print 20000mAh on the shell while holding half that, because no watt-hour rating appears anywhere on the casing. The Budi PB812B carries its 74Wh figure openly, which is the number you can actually check. Budi also runs CE, FCC, and RoHS certification on its cells, and Mascom International backs the unit locally rather than leaving you with a receipt and no recourse.
Can it charge two devices at the same time?
Yes, using the USB-C and USB-A outputs together. Total draw is shared, so two devices each pull roughly half the 22.5W ceiling rather than 22.5W apiece. That suits a phone and earbuds, or a phone and a partner's handset on a long Nairobi to Kisumu bus ride. If you want full speed on one device, unplug the second. Charging a single phone alone always finishes faster than splitting the output.
Is the Budi PB812B safe to leave charging overnight?
Yes. The control board cuts input once the cells reach full charge, and built-in protection circuits guard against overcurrent, overvoltage, over-discharge, short circuits, and overheating. Kenya's mains voltage swings during peak evening load, so pair it with a decent adapter rather than a roadside knock-off. Keep it off bedding and out of direct sun, since heat is the main cause of shortened lithium cell life in Mombasa and Kisumu conditions.
Technical Specifications
Battery Cell and Stored Capacity
- Rated capacity of 20000mAh at 3.7V nominal, equal to 74Wh of stored energy on the casing label.
- Lithium-polymer cell chemistry, chosen over cylindrical cells to keep the casing thin enough for a shirt pocket.
- Usable output lands near 13,000mAh at 5V after conversion losses, the figure that matters for real charge counts.
- Sits under the 100Wh threshold, so no airline approval is needed for cabin carriage on domestic or regional flights.
- Self-discharge stays low, holding most of its stored charge across several weeks of sitting unused in a bag.
- Cell life typically runs 500 or more full cycles before capacity drops noticeably under normal daily use.
Charging Output and Speed Support
- Total output ceiling of 22.5W, shared across active ports rather than delivered separately to each one.
- USB-C port supports Power Delivery 3.0, the standard iPhone, Pixel, and recent Samsung handsets negotiate for faster charging.
- USB-A port supports Quick Charge 3.0, covering Tecno, Infinix, Redmi, and other Qualcomm-based budget handsets sold locally.
- A 5,000mAh handset reaches roughly 50 percent in 30 minutes when connected alone at full available output.
- Low-current mode suits earbuds, fitness bands, and smartwatches that draw too little to trigger normal output.
- Output steps down automatically for devices that request less, protecting older phones from excess current draw.
Port Layout and Recharge Input
- USB-C port handles both input and output, so one cable recharges the pack and charges your phone.
- USB-A output port lets you run a second device or use an existing Lightning or micro-USB cable.
- Recharge input accepts up to 20W over USB-C, filling the pack in roughly five to six hours.
- Pass-through charging lets the pack refill from the wall while simultaneously charging a phone plugged into it.
- Port housings are recessed slightly, reducing the dust ingress common on Nairobi commutes and upcountry road trips.
- No proprietary connectors, so any standard USB-C cable in your drawer works without buying a replacement.
Battery Level Readout and Controls
- Front readout shows remaining charge as a numeric percentage rather than four vague indicator dots.
- Percentage display removes the guesswork of knowing whether enough remains for one more phone refill.
- Single side button wakes the display and starts output for devices that need a manual trigger.
- Display dims and switches off automatically after a short idle period to avoid wasting stored charge.
- Readout also confirms the pack is drawing input, useful when a wall socket or extension cable is faulty.
- Button double-press activates low-current mode for earbuds and other small accessories that stop charging otherwise.
Device Compatibility Across Brands
- Charges any USB-powered device: phones, tablets, earbuds, smartwatches, portable routers, gaming handhelds, and Bluetooth speakers.
- Works with iPhone 15 and newer over USB-C directly, and older iPhones through a Lightning cable.
- Supports Samsung Galaxy A and S series, Tecno, Infinix, Redmi, Oppo, Vivo, and Nothing handsets.
- Keeps a Safaricom or Airtel portable router alive through an evening blackout, holding a home Wi-Fi connection.
- Runs a Bluetooth speaker for several hours at a Diani or Naivasha weekend where sockets are limited.
- Charges a Nintendo Switch or Steam Deck slowly, though a higher-wattage pack suits handheld consoles better.
Build Quality and Daily Durability
- Moulded polycarbonate shell with a matte finish that resists the fingerprints and scuffs of daily bag carriage.
- Rounded edges and a slim profile stop the pack from catching on pockets, laptop sleeves, or backpack dividers.
- Weight sits comfortably in one hand, light enough to carry alongside a phone without noticeable bulk.
- Built-in protection covers overcurrent, overvoltage, over-discharge, short circuit, and overheating across every port.
- Temperature control halts output if internal heat climbs, a real safeguard in Mombasa and Kisumu humidity.
- Certified to CE, FCC, and RoHS standards, confirming the cell and board meet international safety testing.
