UGREEN PB502 10000mAh Two-Way Fast Charging Power Bank is now available at Mascom International for KSh 4,000 at our Old Mutual Building store, First Floor Room 4, Kimathi Street, Nairobi CBD. This 30W portable charger combines a 10000mAh lithium-ion cell, a USB-C Power Delivery 3.0 port, a 22.5W USB-A output with Quick Charge support, and a digital battery percentage display in a 180-gram body that fits any jacket pocket or laptop bag. The UGREEN PB502 supports PD 3.0, QC 4.0, PPS, SCP, FCP, and Apple 2.4A protocols across iPhone, Samsung Galaxy, Huawei, Xiaomi, Oppo, Tecno, and Infinix devices sold in Kenya.
Built for Nairobi office workers, university students at Kenyatta and JKUAT, matatu commuters, field sales teams, and Uber drivers who depend on their phones throughout a 12-hour day, the UGREEN PB502 addresses one specific problem: power outages, long commutes, and full-day meetings drain modern smartphones faster than wall sockets can keep up. The 30W USB-C output charges an iPhone 15 Pro from zero to 60 percent in 30 minutes, and the 10000mAh capacity refills a Samsung Galaxy S24 about 1.8 times, an iPhone 15 about 1.9 times, or a Google Pixel 8 about 1.7 times before needing a top-up itself.
Unlike other electronics retailers in Kenya selling unbranded power banks with inflated mAh claims, the UGREEN PB502 ships with a verified 37Wh battery rating, a UN38.3 transport certification for safe airline travel, and a 6-month Mascom warranty on top of UGREEN's regional warranty. Buyers across Kenya rely on the UGREEN PB502 because it recharges itself fully in about 2 hours through the same USB-C cable that charges their phone, removing the need to carry two separate cables. Visit Mascom International to handle the UGREEN PB502 before you buy, or order for countrywide pay-on-arrival delivery from our Kimathi Street store.
Common Questions About the UGREEN PB502
How many times can the UGREEN PB502 fully charge my phone?
The UGREEN PB502 holds 10000mAh of capacity, which translates to roughly 6250mAh of usable output once voltage conversion losses are factored in. That means the PB502 fully refills an iPhone 15 (3349mAh battery) about 1.9 times, a Samsung Galaxy S24 (4000mAh) about 1.5 times, a Google Pixel 8 (4575mAh) about 1.3 times, or a Tecno Camon 30 (5000mAh) about 1.2 times. For users with smaller phones like the iPhone SE or older Galaxy A models, expect two and a half to three full charges per session before the PB502 needs its own refill.
How fast does the UGREEN PB502 charge an iPhone or Samsung?
The 30W USB-C Power Delivery port pushes an iPhone 15 Pro Max from zero to 60 percent in 30 minutes, faster than Apple's standard 20W adapter manages. Samsung Galaxy S24 and S24 Plus accept the PB502's full 25W Super Fast Charging speed when connected by a USB-C to USB-C cable, reaching 50 percent in about 30 minutes. Older iPhones running Lightning cables charge at lower wattage because of cable limits, not power bank limits. Huawei devices receive SCP fast charging up to 22.5W through the USB-A port.
Can the UGREEN PB502 charge a MacBook Air or iPad Pro?
The 30W USB-C output keeps a MacBook Air M2 running during light tasks like email, web browsing, and document editing, though it charges slowly under heavier workloads like Final Cut Pro or Xcode. An iPad Pro 11-inch accepts the full 30W input and gains roughly 50 percent battery in about an hour. The PB502 works as an emergency top-up for laptops rather than a full charging solution, which is honest positioning Mascom International gives buyers before purchase rather than discovering it afterward.
What devices does the UGREEN PB502 support beyond phones?
The UGREEN PB502 charges any USB-C or USB-A device drawing under 30 watts, including AirPods Pro 2, Galaxy Buds 3, Apple Watch Series 9, Sony WH-1000XM5 headphones, Bluetooth speakers from JBL and Marshall, Garmin watches, GoPro action cameras, DJI Osmo Pocket gimbals, Kindle e-readers, Nintendo Switch in handheld mode, and Steam Deck for short bursts. The pass-through function lets you charge two devices at once while the PB502 itself refills from a wall socket, useful for hotel rooms with limited outlets.
Does the UGREEN PB502 support Safaricom 5G phone fast charging?
5G phones consume more battery than 4G models, making the PB502's 30W output especially relevant for Safaricom and Airtel 5G users running data-heavy apps. The PB502 supports PD 3.0 with PPS (Programmable Power Supply), the protocol Samsung Galaxy S series phones require for full 25W Super Fast Charging speed. iPhone 12 through iPhone 15 series receive 20W minimum on PD, and the OnePlus 12 along with Pixel 8 series both accept rapid charging through the USB-C port. Kenyan 5G coverage in Nairobi, Mombasa, and Kisumu makes battery management critical, and the PB502 handles that load.
How long does the UGREEN PB502 take to recharge itself?
The PB502 supports 30W USB-C input, meaning the same port that charges your phone also refills the power bank in about 2 hours from empty to full. This is roughly three times faster than older power banks limited to 5W or 10W input, which often require 6 to 8 hours of overnight charging. A 25W or higher PD wall adapter unlocks the full 30W input speed. Mascom International stocks compatible UGREEN, Anker, Samsung, and Apple PD adapters for buyers who need a wall charger alongside the PB502.
Is the UGREEN PB502 safe to carry on a Kenya Airways flight?
The UGREEN PB502 carries a 37Wh capacity rating, well under the 100Wh limit airlines including Kenya Airways, Jambojet, Ethiopian Airlines, and Qatar Airways set for carry-on lithium batteries. The PB502 meets UN38.3 transport safety certification, the international standard for lithium battery air transport. Power banks must travel in carry-on luggage, never in checked bags, per IATA rules. The PB502's compact 144 x 71 x 15 millimeter dimensions and 180-gram weight pass through cabin baggage size restrictions on every airline operating from JKIA and Moi International Airport.
Why choose the UGREEN PB502 over Anker, Xiaomi, or Oraimo power banks?
The UGREEN PB502 offers PD 3.0, QC 4.0, and PPS support at 30W in a 180-gram body, where comparable Anker PowerCore Slim 10000 PD models typically cost more in Kenya and lack the digital percentage display. Xiaomi Mi Power Bank 3 offers 22.5W output at a lower price but skips PPS, limiting Samsung Galaxy fast charging speeds. Oraimo and other budget brands often overstate mAh ratings and skip certifications. The PB502 sits in the sweet spot for buyers who want verified specs, brand reliability, and full protocol support without paying top-tier prices.
