Green Lion San Marino Power Bank 20000mAh is now available at Mascom International for KSh 5,700, in stock today at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD. The Green Lion San Marino Power Bank carries a 20,000mAh cell, a USB-C port rated at PD 20W, a USB-A port rated at 22.5W with QC 3.0, and a 15W magnetic wireless pad on its front face. A foldable metal kickstand flips out to hold your phone upright while it charges. The digital LED screen reports the remaining battery as a percentage rather than four vague dots. Model GL-PX88 weighs 420 grams and measures 29 x 69 x 107 mm.
Kenya runs on phones that run out before the day does. Long matatu queues on Thika Road, KPLC outages that stretch past supper, and 12-hour shifts away from any socket all end the same way a dead handset and no way to send an M-Pesa. The Green Lion San Marino Power Bank 20000mAh is built for university students at Kenyatta University, Strathmore and USIU, field engineers covering Nakuru, Eldoret and Kisumu deployments, boda riders navigating between fares, and content creators shooting from morning to night. It refills a 5,000mAh phone battery nearly three times before it needs a socket itself.
At Mascom International, we're seeing buyers walk away from the unbranded 20,000mAh bricks sold on River Road that quietly hold 6,000mAh inside. The Green Lion San Marino Power Bank 20000mAh publishes its output voltages, ships flight-approved, and carries a warranty you can claim at a physical Nairobi CBD counter. Customers across Nairobi report the magnetic pad alone changes how they use a phone on the move snap it on, drop both in one pocket, keep walking. Buy the Green Lion San Marino Power Bank 20000mAh at our Kimathi Street store, or order for pay-on-arrival delivery anywhere in Kenya.
Common Questions About the Green Lion San Marino Power Bank 20000mAh
How many times will the Green Lion San Marino Power Bank actually charge my phone?
Roughly two and a half to three full charges for a typical 5,000mAh phone, and around three for a 4,000mAh iPhone. The 20,000mAh cell holds about 74Wh of energy, but every power bank loses some of that to heat and voltage conversion no honest seller quotes four charges from 20,000mAh. Wired charging through the USB-C or USB-A port gets you the higher figure. Wireless charging through the magnetic pad runs less efficiently, so expect closer to two phone refills if you rely on it exclusively.
Does the Green Lion San Marino Power Bank work with my Samsung, or only iPhone?
Both, though the magnetic pad behaves differently. The 15W wireless pad snaps directly onto iPhone 12 and every newer model because those handsets carry the magnet ring built in. Samsung Galaxy, Tecno, Infinix, Xiaomi and Oppo phones support Qi wireless charging but have no magnets, so they sit on the pad without locking. Add a magnetic ring or a MagSafe-compatible case and they snap on too. The USB-C and USB-A ports charge absolutely any phone, tablet, earbuds or smartwatch regardless of brand.
How fast does it charge my phone compared to a wall charger?
The USB-C port pushes 20W of Power Delivery, which is the same speed as Apple's 20W wall adapter and close to Samsung's 25W brick. That takes an iPhone from empty to roughly half in about 30 minutes. The USB-A port carries 22.5W with Quick Charge 3.0, matching the fast-charge speed most Samsung, Xiaomi and Oppo phones expect. Practical translation: you are not trickle-charging at 5W and waiting three hours. Your phone charges from the Green Lion San Marino Power Bank at close to home-socket speed.
How long does the power bank itself take to refill?
About five to six hours from empty using an 18W or higher PD wall charger through the USB-C port, which accepts 9V/2A. Plug it into a slow 5W phone charger and that stretches past 12 hours, so use a proper fast charger. The practical routine for most Kenyan buyers: plug it in overnight and it is full by morning, KPLC permitting. The digital screen shows the exact percentage climbing, so you always know whether it finished before the power went off.
Can I carry the Green Lion San Marino Power Bank on a Kenya Airways flight?
Yes. The San Marino is flight-approved. Airlines cap lithium batteries in the cabin at 100Wh without prior airline consent, and this unit sits at roughly 74Wh comfortably under the line. The rule that catches travellers out is location: power banks must travel in your hand luggage, never in checked baggage, on Kenya Airways, Jambojet, Emirates, Qatar and every other carrier operating through JKIA. Keep it in your bag, not your suitcase, and security will wave it through without a question.
Can it charge two devices at the same time?
Yes the USB-C port, the USB-A port and the wireless pad can all run together. Be realistic about what happens when they do: 20,000mAh is a fixed budget of energy, and splitting it across three devices drains the bank three times faster. Speeds also drop, since the total output is shared rather than doubled. The sensible use case is one phone charging fast on USB-C while a pair of earbuds or a smartwatch sips slowly on USB-A. Both finish; nothing overheats.
What is the kickstand for, and does it matter?
It turns the power bank into a phone stand while charging, which sounds minor until you use it. Snap your iPhone onto the magnetic pad, flip the stand out, and you have a hands-free screen at a viewing angle for a Zoom call from a hotel room in Kisumu, a Netflix episode on a Mombasa bus, or a recipe propped on the kitchen counter. Most 20,000mAh power banks give you a brick and a cable. This one charges your phone and holds it upright at the same time.
Will the Green Lion San Marino Power Bank charge my laptop?
Only lightly, and only some laptops. The USB-C port outputs 20W, while a MacBook Air asks for 30W and most HP, Dell and Lenovo ultrabooks want 45W to 65W. Plugged into a modern USB-C laptop, the San Marino slows the battery drain and may add a slow trickle when the machine is asleep it will not run a full work session. Buyers who need real laptop power should ask our Kimathi Street team about the higher-wattage PD power banks Mascom International stocks.

- USB-C output rated 5V/3A, 9V/2.22A, 12V/1.67A for a peak of PD 20W across compatible phones

- Quick Charge 3.0 on the USB-A port covers Samsung, Xiaomi, Oppo, Tecno and Infinix fast-charge standards
- Both ports run simultaneously, sharing total output between two devices rather than doubling it
- Automatic voltage negotiation means one cable serves earbuds at 5W and a phone at 20W safely
Magnetic Wireless Charging Hardware
- 15W wireless pad on the front face charges any Qi-compatible phone laid flat on it
- Magnet array aligns with iPhone 12 through the current generation, snapping on and staying put
- Android handsets need a magnetic ring or MagSafe-compatible case to lock onto the pad
- Cable-free charging while the phone rides in a jacket pocket, bag or matatu seat back
- Wireless transfer loses more energy to heat than wired, so plan on around two phone refills
- Lightning icon on the screen lights up automatically once wireless charging engages
Battery Capacity and Recharge Behaviour
- 20,000mAh lithium cell holding roughly 74Wh, enough for around three charges of a 4,000mAh phone
- USB-C input accepts 5V/3A and 9V/2A for an 18W peak recharge rate into the bank
- Full refill takes approximately five to six hours from an 18W or stronger PD wall charger

- One press of the power button wakes the screen to report the exact level before you leave home
- Green Lion advises a top-up charge every three months if the unit sits unused in a drawer

- Tops up AirPods, Galaxy Buds, JBL earbuds, smartwatches and fitness bands through either port
- Runs Bluetooth speakers, portable Wi-Fi routers and Safaricom MiFi units on the USB-A port
- USB-C laptops draw a slow supplementary charge only, as 20W falls short of a 45W requirement
- Works with any standard USB-C or USB-A cable, no proprietary Green Lion accessory needed
Build Quality and Daily Durability
- ABS shell measuring 29 x 69 x 107 mm — roughly a phone's footprint and just under 3 cm thick

- Foldable stand flips out to hold a magnetically attached phone upright for hands-free viewing
- Lanyard hole takes a wrist strap or carabiner, useful for site engineers and hikers

Safety Protection and Travel Compliance
- Multi-stage protection guards against overcharge, over-discharge, short circuit and overheating
- Operating warmth up to 55°C during charging is normal behaviour, not a fault
- Flight-approved rating clears the unit for cabin carry-on across airlines operating through JKIA
- 74Wh capacity sits under the 100Wh airline threshold that requires prior carrier approval
- Voltage matching prevents damage when charging low-draw devices such as earbuds and watches
- Keep the unit dry and away from chemical cleaners, per Green Lion's official handling guidance
