Green Lion Xtreme 20 Power Bank packs 20000mAh of capacity, 22.5W fast charging, and a built-in Lightning cable into one compact unit, now available at Mascom International for KSh 4,000. You can buy it at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD. The Green Lion Xtreme 20 carries USB-C and USB-A outputs alongside the attached cable, so most phones charge straight out of the box. An LCD screen shows the exact battery percentage, removing the guesswork that comes with four-dot indicator strips on cheaper banks.
The Green Lion Xtreme 20 Power Bank suits people who spend long hours away from a wall socket. Boda boda riders running Bolt and Uber shifts, field sales reps covering Nairobi to Nakuru routes, and university students at JKUAT or Kenyatta University moving between lecture halls all face the same problem: a phone that dies by mid-afternoon. The Green Lion Xtreme 20 solves this by holding enough charge to refill a typical 4500mAh phone roughly three times before it needs a recharge itself.
At KSh 4,000, the Green Lion Xtreme 20 sits in a price band crowded with unbranded banks that overstate their capacity. Buyers across Kenya tell us they have moved away from no-name units that lose capacity within months. The Green Lion Xtreme 20 ships with a 12-month warranty backed directly by our Nairobi CBD service desk. Walk into Mascom International to weigh it in your hand, or order for pay-on-arrival delivery to any of Kenya's 47 counties.
Questions Buyers Ask About the Green Lion Xtreme 20 Power Bank
How many times can the Green Lion Xtreme 20 charge my phone?
The Green Lion Xtreme 20 recharges most phones two to three full times on a single fill. Its 20000mAh rating translates to roughly 12000mAh to 13000mAh of usable output after conversion losses, which every power bank experiences. A phone with a 4500mAh battery like a Samsung Galaxy A55 takes about three charges. A larger 5000mAh phone manages two and a half. That covers a full weekend trip to Kisumu or Mombasa without hunting for a socket.
Does the Green Lion Xtreme 20 have a built-in cable?
Yes, the Green Lion Xtreme 20 includes an integrated Lightning cable attached to the body. This means iPhone users can charge without carrying a separate cord. The bank also carries a USB-C output and a USB-A output for Android phones, tablets, and accessories. You can charge up to three devices at once across the built-in cable and the two ports, making it useful when you and a colleague both need power during a long matatu ride.
How fast does the Green Lion Xtreme 20 charge?
The Green Lion Xtreme 20 pushes up to 22.5W through its USB-A output and 20W through USB-C with Power Delivery. A 22.5W output refills a compatible phone to around 50 percent in about 30 minutes, far quicker than the 10W banks common in this price range. Fast charging matters when you only have a short coffee break in Westlands to top up before your next client meeting. Actual speed depends on your phone supporting the matching standard.
Is the Green Lion Xtreme 20 allowed on flights?
Yes, the Green Lion Xtreme 20 sits within airline carry-on rules. At 20000mAh, its energy rating works out to roughly 74Wh, comfortably under the 100Wh limit that Kenya Airways, Jambojet, and most international carriers allow in hand luggage. You cannot pack any power bank in checked baggage, so keep the Green Lion Xtreme 20 in your carry-on bag. This makes it a sensible pick for frequent travelers flying out of JKIA or Moi International Airport.
Is the Green Lion Xtreme 20 worth KSh 4,000 in Kenya's market?
For a branded 20000mAh bank with 22.5W charging and a built-in cable, KSh 4,000 is fair value. Unbranded banks at this price often claim 20000mAh but deliver far less, then fade within a year. Green Lion units carry CE, FCC, and RoHS safety certification, which the no-name alternatives rarely hold. The 12-month Mascom International warranty means a faulty unit gets handled at our counter, not written off as a loss.
What devices work with the Green Lion Xtreme 20?
The Green Lion Xtreme 20 charges nearly any USB device. iPhones use the attached Lightning cable. Android phones from Samsung, Tecno, Infinix, Xiaomi, and Oppo charge through the USB-C or USB-A output with your own cable. It also tops up earbuds, smartwatches, Bluetooth speakers, and tablets. The 22.5W output covers Quick Charge phones, while the 20W USB-C Power Delivery handles modern devices that expect PD input.
How does the LCD display help day to day?
The LCD screen shows the exact remaining charge as a number from 1 to 100 percent. This tells you precisely when to recharge instead of guessing from blinking dots. Knowing you have 35 percent left helps you decide whether to risk a day out without a wall charger. The display stays readable under direct Nairobi sunlight, useful for outdoor workers at construction sites or open-air markets across the country.
How long does the Green Lion Xtreme 20 take to recharge itself?
The Green Lion Xtreme 20 refills through its USB-C input. Using a 20W or higher wall charger, a full recharge takes roughly four to five hours depending on the adapter. A standard 5W phone charger will take far longer, often overnight. We recommend pairing it with a 20W or 25W USB-C wall charger, which Mascom International stocks separately, to keep recharge times short between trips.
