Green Lion Nairo 20000mAh Power Bank is now in stock at Mascom International for KSh 2,800, available at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD. This portable charger holds a 20000mAh (74Wh) cell with a rated output of 11200mAh, fast 20W USB-C Power Delivery, a 22.5W USB-A port, and a digital percentage display. It is flight-approved for carry-on travel. The Green Lion Nairo refills phones, tablets, earbuds, and small devices through a single pocket-sized unit, sold at one of the clearest prices in Kenya's accessory market.
The Green Lion Nairo 20000mAh suits university students at Kenyatta and JKUAT who lose charge between lectures, matatu commuters facing long stalls along Thika Road, and boda boda riders who run navigation apps all day. Field officers working for NGOs in Turkana, Marsabit, and Garissa often go hours without a wall socket. Power outages still interrupt work across many estates and upcountry towns. The Green Lion Nairo addresses that gap directly, holding enough charge to refill a typical smartphone three to four times before the pack itself needs a top-up.
At Mascom International, we're seeing strong demand for honest mid-capacity power banks that state real numbers instead of inflated capacity claims. The Green Lion Nairo lists its rated output openly at 11200mAh, which is the figure that actually reaches your phone. Buyers across Kenya rely on Mascom International for accurate specifications and pay-on-arrival delivery. Visit our Nairobi CBD store to test the Green Lion Nairo before you buy, or order it for delivery to any of Kenya's 47 counties with payment due only on arrival.
Questions Buyers Ask About the Green Lion Nairo 20000mAh Power Bank
How many times will the Green Lion Nairo charge my phone?
The Green Lion Nairo holds 20000mAh with a rated usable output of 11200mAh, enough for roughly three to four full smartphone charges. A typical phone with a 4500mAh to 5000mAh battery refills about two and a half times from the rated capacity. Energy is always lost as heat during transfer, which is why rated output sits below the headline number. For a Samsung Galaxy A17 or an iPhone you can expect three school days or work days of backup from one full pack.
Is the Green Lion Nairo worth KSh 2,800 in Kenya's market?
At KSh 2,800 the Green Lion Nairo sits well below many 20000mAh packs sold in Nairobi shops, which often run KSh 3,500 to KSh 5,000. You get real 20W USB-C Power Delivery, a 22.5W Quick Charge USB-A port, and a digital display at this price. Cheap unbranded packs at this capacity rarely include fast charging or honest rated figures. The Green Lion Nairo carries a verified warranty through Mascom International, so the KSh 2,800 buys backed performance, not a gamble.
Can the Green Lion Nairo fast charge my phone?
Yes. The USB-C port outputs 20W Power Delivery, and the USB-A port reaches 22.5W with Quick Charge 3.0 support. A 20W feed pushes a compatible iPhone or Android phone from empty to about 50 percent in roughly 30 minutes. The Green Lion Nairo refills modern phones far quicker than the old 5W and 10W packs still common across Kenya. Confirm your phone supports PD or QC fast charging to pull the highest speed available.
Is the Green Lion Nairo allowed on flights?
Yes, the Green Lion Nairo is flight-approved for carry-on luggage. At 74Wh it sits under the 100Wh limit that airlines including Kenya Airways and Jambojet apply to lithium batteries in hand baggage. You must carry power banks in the cabin, never in checked bags, per international aviation rules. The Green Lion Nairo travels cleanly through Jomo Kenyatta International Airport security and serves business travellers and tourists moving between Nairobi, Mombasa, and Kisumu without charging worries.
What devices can the Green Lion Nairo charge?
The Green Lion Nairo charges phones, tablets, wireless earbuds, smartwatches, fitness bands, and small Bluetooth speakers. The 20W USB-C port handles phones and small tablets at fast speed, while the dual outputs let you charge two devices at once. It does not carry enough wattage to run most laptops, which need 45W or higher. For Samsung Galaxy phones, iPhones, Tecno, Infinix, Oppo, and Xiaomi handsets common in Kenya, the Green Lion Nairo covers a full day of mixed use comfortably.
How long does the Green Lion Nairo take to recharge?
The Green Lion Nairo recharges through its USB-C input at up to 20W, refilling the full 20000mAh pack in roughly four to five hours with a compatible wall charger. A standard 5W phone charger will take far longer, often eight hours or more. For the quickest top-up, Mascom International stocks 20W and higher USB-C PD wall adapters separately. Plug the Green Lion Nairo in overnight and it sits ready each morning for a full day away from sockets.
What does the digital display on the Green Lion Nairo show?
The digital display shows the remaining battery level as a clear percentage from 1 to 100. This removes the guesswork of the four-dot LED strips found on cheaper power banks, where you never know if 25 percent means 25 or nearly empty. You can see at a glance whether the Green Lion Nairo holds enough charge before leaving home for a long day. The readout stays visible in bright equatorial sunlight, useful for outdoor and field use across Kenya.
How durable is the Green Lion Nairo for daily Kenyan use?
The Green Lion Nairo uses a tough ABS and polycarbonate shell built to survive daily knocks in bags and pockets. Built-in protection circuits guard against overcharging, over-discharge, short circuits, and overheating, which matters in Kenya's warm climate. The slim body slides into a jacket pocket, handbag, or laptop sleeve without bulk. Users consistently report that branded packs like the Green Lion Nairo outlast cheap market alternatives that swell or fail within months.
