The oraimo PowerFlow B11 10000mAh 15W Power Bank is now available at Mascom International for KSh 1,500, in stock at our Old Mutual Building store, First Floor Room 4, Kimathi Street, Nairobi CBD. This portable battery packs 10,000mAh (37Wh) into a slim body, pushes up to 15W through one USB-C port and two USB-A ports, and recharges over the same USB-C cable. oraimo lab figures put it at roughly two full charges for an iPhone 15 Pro.

The oraimo PowerFlow B11 suits university students at JKUAT, Kenyatta, and USIU who stretch a single charge across long lecture days, boda boda riders navigating by phone, and small-business owners running M-Pesa transactions from morning till late. Kenya's frequent KPLC power interruptions leave many phones dead by evening. This power bank answers that gap: a pocket-sized battery that tops up a phone during a matatu ride home or a load-shedding stretch. Content creators filming on the go, sales teams moving between meetings, and anyone far from a charger gains hours of extra runtime from the oraimo PowerFlow B11.
Unlike unbranded power banks sold cheaply across Nairobi's streets, the oraimo PowerFlow B11 carries oraimo's 15-layer protection system guarding against overheating, overcharging, and short circuits. Buyers across Kenya tell us the difference shows in how long the battery holds up. At Mascom International, we stock genuine oraimo units, not counterfeits that swell or fail within weeks.

Common Questions About the oraimo PowerFlow B11 Power Bank
How many times will the oraimo PowerFlow B11 charge my phone?
oraimo's lab tests put the oraimo PowerFlow B11 at roughly two full charges for an iPhone 15 Pro, about 1.6 charges for a Samsung Galaxy S24, and around 1.2 charges for a Tecno Camon 20 Premier. The 10,000mAh (37Wh) cell translates to real-world usable capacity of roughly 6,000 to 6,500mAh after voltage conversion, which covers most Kenyan smartphones fully once with charge to spare. For a typical 5,000mAh Tecno or Infinix phone, expect a bit over one full top-up from a single PowerFlow B11 charge.
Is the oraimo PowerFlow B11 fast enough to charge quickly?
The oraimo PowerFlow B11 pushes up to 15W, and oraimo measures an iPhone 15 climbing to 45% in 30 minutes, against roughly 10% from an old 5V/1A power bank. AniFast technology reads your phone's charging protocol and matches it, so compatible devices pull their fastest safe speed. This is not a 30W or 65W laptop charger; it targets phones, earbuds, and smartwatches. For a school day or a matatu commute across Nairobi, 15W refills enough battery during a short stop to keep you going for hours.
Can the oraimo PowerFlow B11 charge three devices at the same time?
Yes. The oraimo PowerFlow B11 has three output ports, two USB-A and one USB-C, so you can charge a phone, wireless earbuds, and a smartwatch together. The combined output stays at up to 15W across all connected devices, meaning speed splits between them when several draw power at once. For a family sharing one battery on a road trip to Nakuru or Kisumu, or a content creator topping up a phone and microphone between shots, three ports remove the wait for a single free socket.
How do I recharge the oraimo PowerFlow B11 itself?
The oraimo PowerFlow B11 recharges through its USB-C port, the same port used for output, so one USB-C cable handles both jobs. Plug it into any standard phone charger, laptop USB-C port, or wall adapter. A side button and indicator lights show remaining charge when you press it, so you know before leaving home whether the battery is topped up. There is no separate micro-USB input to worry about, which cuts cable clutter for anyone already carrying a USB-C phone charger day to day.
Is the oraimo PowerFlow B11 safe for my phone and does it overheat?
The oraimo PowerFlow B11 runs a 15-layer protection system that guards against overheating, overcharging, over-discharging, and short circuits, cutting power if something goes wrong. Early reviewers report no notable heating during normal charging. This matters in Kenya, where cheap unbranded banks sometimes swell, leak, or damage phones. The 3D-textured shell resists scratches and gives a firm grip, lowering the chance of drops. Buying a genuine oraimo unit from Mascom International, rather than a street copy, is the clearest way to protect your phone.
Will the oraimo PowerFlow B11 work with my iPhone, Samsung, or Tecno?
The oraimo PowerFlow B11 works with virtually any phone that charges over USB, including iPhone, Samsung Galaxy, Tecno, Infinix, Xiaomi, Redmi, and Oppo models. The two USB-A ports pair with your existing USB-A to Lightning or USB-A to USB-C cables, while the USB-C port fits modern USB-C phones directly. AniFast technology adjusts to each device's supported speed. Note that you supply the cable that matches your phone; the box includes a USB-C cable for recharging the bank and charging USB-C phones.
Is the oraimo PowerFlow B11 worth KSh 1,500 in Kenya's market?
At KSh 1,500, the oraimo PowerFlow B11 sits at the affordable end of branded 10,000mAh banks in Kenya, well below top-tier names charging KSh 3,000 or more for similar capacity. You get genuine oraimo build quality, a 15-layer protection system, three ports, and Type-C in and out. Spread across an expected lifespan of a couple of years, that is a small cost for daily phone insurance against KPLC blackouts and long days away from a charger. Mascom International backs it with a 6-month warranty.
How portable is the oraimo PowerFlow B11 for daily carry?
The oraimo PowerFlow B11 keeps a slim, lightweight profile that slides into a trouser pocket, handbag, or laptop sleeve without weighing you down. oraimo built it around portability, so it carries easily on a boda boda, in a matatu, or in a backpack during a Nyeri or Eldoret road trip. The 3D-textured graphite finish hides fingerprints and resists slips from sweaty hands. For students, field staff, and commuters who already haul a laptop and charger, the oraimo PowerFlow B11 adds backup power without adding bulk.
