Pocket Charger That Keeps Your Phone Alive Through Long Nairobi Days
Condition: New
Note: price and availability are subject to change without prior notice
Anker PowerCore Slim 10000 is now available at Mascom International for KSh 4,000, ready for collection at our Old Mutual Building location, First Floor Room 4, Kimathi Street, Nairobi CBD. The Anker PowerCore Slim 10000 packs a 10,000mAh cell into a half-pound shell that slides into a back pocket, a laptop sleeve, or the inside flap of a handbag without bulking it out. It charges most phones up to three times on a full tank and tops up tablets once, making it the right size for daily commutes rather than weekend camping trips.
Built for Kenyans who spend their days moving between meetings, matatus, and unreliable wall sockets, the Anker PowerCore Slim 10000 addresses the single biggest frustration facing professionals across Nairobi: a dead phone at 3 PM. Tech workers based in Westlands, Kilimani, and Lavington use it to keep WhatsApp, Slack, and email running between client visits. Field engineers covering Nakuru, Eldoret, and Kisumu deployments rely on it during long site days where charging access is limited. University students at JKUAT, Strathmore, and the University of Nairobi keep it in their bags for late library sessions when laptops and phones drain faster than expected.
Unlike traditional electronics retailers in Kenya who stock unbranded power banks with inflated capacity claims, Mascom International only stocks genuine Anker units with real-world tested capacity and the brand's safety circuitry built in. Customers across Nairobi report that one Anker PowerCore Slim 10000 outlasts three to four of the cheap copies they used before. Walk into our Kimathi Street showroom to weigh it in your hand, or order through countrywide pay-on-arrival delivery and confirm the unit before you part with KSh 4,000.
Frequently Asked Questions about Anker PowerCore Slim 10000
How many full phone charges does the Anker PowerCore Slim 10000 actually deliver?
The Anker PowerCore Slim 10000 charges most modern smartphones around two to three times before it needs a refill. An iPhone 14 or 15 gets close to two complete cycles. A Samsung Galaxy A35 or Galaxy S24 manages roughly two charges. Smaller phones like the iPhone SE or older Galaxy A models stretch to three. Real-world numbers drop slightly because of voltage conversion losses, but two solid top-ups from 0 to 100 percent are realistic for almost every phone Mascom International sells.
Is the Anker PowerCore Slim 10000 worth KSh 4,000 in Kenya's market?
Yes, especially when compared to the unbranded 10,000mAh banks selling for KSh 1,500 to KSh 2,500 in River Road and Luthuli Avenue stalls. Those cheap units rarely deliver more than 5,000mAh of usable power despite the printed numbers, and many fail within four to six months. The Anker PowerCore Slim 10000 carries a real 10,000mAh cell, holds its charge for weeks during storage, and ships with Anker's MultiProtect safety circuitry that prevents overheating and short circuits.
How fast does the Anker PowerCore Slim 10000 charge a phone?
The single USB-A output runs at 5V/2.4A, which equals 12 watts of charging output. That speed matches a standard wall charger for most phones, taking an iPhone 15 from 0 to 50 percent in roughly 35 minutes. It does not match wall-based fast charging on Samsung 25W Super Fast Charge or Xiaomi 67W HyperCharge, but it pushes enough current to handle a quick top-up while you're stuck in Mombasa Road traffic or waiting at JKIA.
How long does the Anker PowerCore Slim 10000 take to recharge itself?
A full recharge takes about 4.5 hours when paired with a 2A wall charger over the USB-C input port. Using a slower 1A phone charger pushes the time to roughly 9 to 10 hours, so plug it in overnight if you only have a basic charger. The included Micro-USB cable also works for recharging the bank itself, though USB-C is faster. Note that the USB-C port on this model is input-only and cannot charge other devices.
Can the Anker PowerCore Slim 10000 charge two devices at once?
The standard PowerCore Slim 10000 has one USB-A output port, so it charges one device at a time. Customers who need to power two phones simultaneously, or a phone and earbuds together, should ask our team about the Anker PowerCore Slim 10000 PD version which adds a second port and 18W USB-C Power Delivery output. The single-output version reviewed here keeps the price down and the body slim.
Does the Anker PowerCore Slim 10000 work with iPhones, Samsung phones, and Bluetooth earbuds?
Yes. The USB-A output works with any phone, tablet, smartwatch, or wireless earbud that charges over a standard USB cable. The PowerIQ chip detects which device is connected and adjusts the output accordingly, so iPhones receive Apple's preferred profile and Samsung devices get the right voltage. For low-power devices like AirPods, Galaxy Buds, or Bluetooth headphones, the trickle-charging mode prevents the bank from cutting off too early. Activate trickle mode by pressing the power button twice or holding for two seconds until the LED turns green.
Is the Anker PowerCore Slim 10000 allowed on flights from JKIA?
Yes, the 10,000mAh capacity equals 37 watt-hours, which sits well below the 100Wh airline limit for carry-on lithium batteries. Kenya Airways, Qatar Airways, Emirates, and Ethiopian Airlines all permit this size in hand luggage. Pack it in your carry-on bag, never in checked luggage, and you'll clear JKIA, Wilson, Mombasa Moi, or Eldoret International security without issue. Take this Anker PowerCore Slim 10000 along on Diani weekend trips, Maasai Mara safaris, or international business travel without paperwork.
Why choose theAnker PowerCore Slim 10000 over a generic 10,000mAh power bank?
Three reasons matter for Kenyan buyers: real capacity, build quality, and safety. Generic power banks routinely overstate capacity by 30 to 50 percent. Anker's tested 10,000mAh delivers what the label claims, with Anker's MultiProtect system guarding against overheating, short circuits, and voltage spikes. Generic banks cause dozens of phone-damaging incidents Mascom International sees through repair requests every year. The Anker brand also holds resale value if you upgrade later, which a no-name unit never does.
How does the Anker PowerCore Slim 10000 hold up to daily use?
The aluminum-finish polycarbonate shell handles the realities of Kenyan life: keys in pockets, drops onto matatu floors, and dust on Thika Road or Mombasa Road. Anker tests the body to a 1-meter drop standard, and users report cosmetic scratches but no functional failures after years of pocket carry. The four LED indicators on the front confirm remaining charge with a single button press, so you always know whether to top up before leaving the house.
