Mascom International stocks the Anker PowerCore Slim 10000mAh at KSh 4,000, brand new and sealed, with a 10,000mAh cell, up to 12W output and a thin flat body. Anker rates it at about 2.25 charges of an iPhone 12 or 1.6 charges of a Samsung Galaxy S20. The Anker PowerCore Slim 10000mAh refills through either USB-C or Micro USB and charges your phone from a USB-A port. At KSh 4,000, the Anker PowerCore Slim 10000mAh costs KSh 1,000 less than the Anker 323 Power Bank 10000mAh, which holds the same capacity. Collect it from our shop at Old Mutual Building, Kimathi Street, Nairobi CBD.
Built for executives, lawyers, doctors and journalists across Kenya, the Anker PowerCore Slim 10000mAh fills a quiet but common need: backup power that does not spoil the line of a suit pocket or weigh down a slim bag. A day of court sessions, ward rounds or meetings in Upper Hill leaves little time to find a socket, and phones running email, maps and banking apps fade by evening. The Anker PowerCore Slim 10000mAh sits flat against your phone, so you can charge while walking between buildings or riding a matatu home.
Unlike other electronics retailers in Kenya that mix copies with genuine stock, Mascom International sells only authentic Anker power banks bought through proper channels. At Mascom International, we're seeing professionals pick the Anker PowerCore Slim 10000mAh as a first power bank, because it is light enough to carry every day and cheap enough to keep one at home and one in the office. Visit the Kimathi Street store to hold it next to your phone, or order on WhatsApp and pay on arrival. Each unit carries a 6-month warranty.
Common Questions About the Anker PowerCore Slim 10000mAh
How much is the Anker PowerCore Slim 10000mAh in Kenya?
The Anker PowerCore Slim 10000mAh costs KSh 4,000 brand new at Mascom International, Kimathi Street, Nairobi CBD. That price buys a sealed Anker unit, the Micro USB cable packed in the box and a 6-month warranty handled at our Nairobi CBD service desk. A wall adapter is not included. Delivery is pay-on-arrival across all 47 counties. The Anker 323 Power Bank 10000mAh, at KSh 5,000, adds a USB-C output for KSh 1,000 more.
How many times will the Anker PowerCore Slim 10000mAh charge my phone?
The Anker PowerCore Slim 10000mAh gives about 2.25 charges of an iPhone 12 or about 1.6 charges of a Samsung Galaxy S20, according to Anker. Phones with bigger batteries, such as Tecno and Infinix models carrying 5000mAh or more, get closer to one and a half full charges. Every power bank loses some energy to heat while transferring charge, which is why the totals fall below the headline figure. For most people that still means a full spare day of calls and messaging.
Should I buy the Anker PowerCore Slim 10000mAh or the Anker Pocket-Size Power Bank 10000mAh 30W?
Choose the Anker PowerCore Slim 10000mAh if price and a flat shape matter most; choose the Anker Pocket-Size Power Bank 10000mAh 30W if charging speed matters most. Both hold 10,000mAh. The Slim charges at up to 12W from a USB-A port for KSh 4,000. The Pocket-Size model costs KSh 6,500 and reaches 30W, which fast-charges recent phones and some tablets. Users of older or budget phones that charge slowly anyway lose little by picking the Slim.
Can the Anker PowerCore Slim 10000mAh keep my Safaricom router running during a power cut?
Yes, the Anker PowerCore Slim 10000mAh can power a pocket Wi-Fi router from Safaricom, Airtel Kenya or Telkom through its USB-A port during a KPLC blackout. Many home routers charge or run over USB, so the bank keeps you online while the lights are out in Kileleshwa or Kahawa. Running time depends on the router's own draw, so treat it as a few hours of backup rather than a whole night. Charge your phone first if the outage looks long.
Does the Anker PowerCore Slim 10000mAh work with a USB-C phone?
Yes, the Anker PowerCore Slim 10000mAh charges USB-C phones using a USB-A to USB-C cable plugged into its output port. Its USB-C port takes power in only; it does not charge devices. That means a cable with USB-A on one end, which comes with many Tecno, Infinix and Redmi phones sold in Kenya. If all your cables are USB-C to USB-C, the Anker 323 Power Bank 10000mAh, with its two-way USB-C port, is the easier match.
Is the Anker PowerCore Slim 10000mAh a sensible gift for a graduate or new employee?
Yes, the Anker PowerCore Slim 10000mAh makes a practical gift for graduates from Strathmore, USIU or the University of Nairobi starting their first job. It looks neat on a desk, fits a work bag and solves a problem every new employee meets: a phone dying during a long first week. At KSh 4,000 it sits within most gift budgets. Mascom International can deliver it sealed to the recipient anywhere in Kenya, with payment on arrival if you prefer.
Who should buy the Anker PowerCore Slim 10000mAh, and who should skip it?
The Anker PowerCore Slim 10000mAh suits professionals, students and parents who want a light, low-cost backup for one phone and accept standard charging speed. Skip it if you need to charge two devices at once, since it has a single output. Skip it too if you want several days of blackout cover; the Anker 325 Power Bank 20000mAh at KSh 5,500 stores twice the energy. Fast-charging phone owners are better served by a 22.5W or 30W Anker model.
How do I recharge the Anker PowerCore Slim 10000mAh?
You recharge the Anker PowerCore Slim 10000mAh from any USB wall adapter, using either a USB-C cable or the Micro USB cable included in the box. Plug it in overnight and it is ready by morning. A laptop USB port also works, though more slowly, which helps on a long day at your desk in Westlands. The indicator lights show progress, so you know when the bank is full and can unplug it.
Technical Specifications
Core Function and Capacity
- 10,000mAh capacity — about 2.25 charges of an iPhone 12, according to Anker, from one full charge of the bank.
- Up to 12W output — standard-speed charging that suits phones, earbuds, smartwatches and pocket Wi-Fi routers alike.
- Single USB-A output port — plug in the USB cable that came with your phone and charging starts.
- USB-C input — refill the bank with the same USB-C cable most current Android phones use every day.
- Micro USB input — a second way to recharge, useful in homes and offices still full of older cables.
- Anker PowerIQ charging — the bank detects the connected device and supplies the current it can safely accept.
Compatibility
- Charges iPhone through a USB-A to Lightning or USB-A to USB-C cable, depending on the model you own.
- Charges Samsung, Tecno, Infinix, Oppo, Redmi and other Android phones with any USB-A cable that fits them.
- Powers wireless earbuds, fitness bands and Bluetooth speakers — devices that need only gentle, steady current.
- USB-C port is input only — it refills the bank but does not send power out to a phone.
- No laptop charging — 12W is far too little to run or charge a notebook computer.
- Fast-charging phones work at standard speed — expect slower top-ups than their own quick chargers deliver.
Build and Safety
- Thin, flat profile — lies against the back of a phone so you can hold both in one hand while charging.
- Light enough for daily carry — slips into a shirt pocket, blazer, clutch bag or laptop sleeve without fuss.
- Indicator lights — show remaining charge at a glance so the bank is not empty when you reach for it.
- Anker protection circuits — help guard against overcharging, overheating and short circuits during long charging sessions.
- Under the 100Wh cabin limit most airlines apply — pack it in your carry-on, never in checked luggage.
Inclusions
- Anker PowerCore Slim 10000mAh — sealed, brand new retail stock in original Anker packaging.
- Micro USB cable — recharges the bank from any USB wall adapter or laptop USB port.
- Welcome guide — explains the indicator lights and the safe way to charge and store the bank.
- No wall adapter and no USB-C or Lightning cable — use the leads you already own at home.
- Colour: black is the usual stock; confirm the shade on the shelf over WhatsApp before ordering.
