Quick answer: Both the Anker Zolo 25,000mAh 165W (KSh 11,900) and the oraimo PowerJet 130 27,600mAh (about KSh 8,000) can charge a USB-C laptop at up to 100W from a single port. Pick the Anker Zolo if you want built-in cables, four-device charging and an 18-month warranty. Pick the oraimo PowerJet 130 if you want the most capacity per shilling and a faster 1.5-hour self-recharge.
If you work from cafés, campus or client sites around Nairobi, or you just want a laptop that survives the next blackout, a phone-grade power bank won't cut it. You need one that speaks USB-C Power Delivery at laptop wattages. These two are among the strongest options you can buy in Kenya today, and they get there in different ways.
What makes a power bank good for laptops?
A laptop power bank needs four things. Both of these models tick all four.
- USB-C Power Delivery (PD) at 60W–100W. Most USB-C laptops draw 45W–100W. A 22.5W phone power bank will barely slow the drain. Both models deliver up to 100W from one USB-C port.
- At least 20,000mAh (roughly 75Wh+). Laptop batteries are 40Wh–100Wh, so smaller banks give you half a charge at best. These two hold 90Wh and 99.3Wh.
- A fast self-recharge. A big battery that takes 8 hours to refill is useless during load-shedding. Both refill at 100W.
- Under the 100Wh airline limit. Both are rated below 100Wh, so they can go in your hand luggage.
One important check: your laptop must charge through USB-C. Laptops with a round barrel charger, or a USB-C port that only carries data, cannot be charged by either power bank. Look for a battery or lightning icon beside the USB-C port, or check your laptop's spec sheet for "USB-C PD charging".

Anker Zolo 25,000mAh 165W: the no-cables-needed workhorse
The Zolo's standout feature is that its cables are part of the body. One USB-C cable (about 70 cm) retracts into the unit; a second, shorter one doubles as a carry strap. You never arrive at a meeting with the power bank but without the cable.
- Laptop power: up to 100W from one USB-C connection. Anker's own test charges a 16-inch MacBook Pro (M3) to 50% in 33 minutes.
- Most total output: 165W shared across four devices, so a laptop, phone, earbuds and a tablet can all charge together.
- Second high-power USB-C: unlike the oraimo, more than one port can deliver serious wattage, which helps if you carry two laptops or a laptop plus a large tablet.
- Recharge: 100W input on any USB-C port; about 30% in 20 minutes and full in roughly 2 hours.
- Safety: ActiveShield 2.0 monitors temperature over 3 million times a day.
- Warranty: 18 months, which you can claim in person at the Anker Soundcore Kenya shop on Luthuli Avenue, Nairobi CBD.
Trade-offs: it costs about KSh 3,900 more than the PowerJet 130 and holds slightly less energy (90Wh vs 99.3Wh). At 595 g, it is a bag item, not a pocket item.
oraimo PowerJet 130 27,600mAh: the most capacity for your money
The PowerJet 130 packs 99.3Wh, just under the airline ceiling, at roughly two-thirds of the Anker's price. For a buyer whose main goal is "keep my laptop alive through a long outage", that is a lot of battery per shilling.
- Laptop power: up to 100W from the USB-C1 port, enough for MacBook Pro, MacBook Air, HP Spectre and ZBook, Dell, Lenovo ThinkPad and Surface Book models that charge over USB-C.
- Biggest capacity of the two: oraimo's lab rates it at about 2 MacBook Air charges or 5.5 iPhone 15 charges.
- Fastest self-recharge: full in about 1.5 hours with a 100W charger, using the 100W cable included in the box.
- Laptop + phone together: 100W on USB-C1 plus 30W on USB-C2 (130W total). With all three ports in use, total output drops to 115W.
- Low-current mode: double-press the power button to safely charge smartwatches and earbuds.
- Built to last: automotive-grade cells; oraimo states 80% capacity remains after 800+ charge cycles.
- Social proof: 4.9 stars from 753 reviews on ke.oraimo.com, with Kenyan buyers praising it for blackouts and remote work.
Trade-offs: only one port can feed a laptop at full speed, the second USB-C tops out at 30W, and you carry a separate cable. The warranty is 1 year (replacement), shorter than Anker's 18 months.

Why both are good laptop power banks
Either one will genuinely run and charge a USB-C laptop, which most power banks sold in Kenya cannot.
- Real laptop wattage. 100W USB-C PD covers everything from a MacBook Air to a 16-inch MacBook Pro or a business-class Dell or ThinkPad. Many "big" power banks on the market stop at 18W–22.5W.
- Laptop-sized batteries. At 90Wh and 99.3Wh, each holds roughly one to two full laptop charges, depending on the laptop.
- Charge the laptop and phone together. Both keep 100W going to the laptop while topping up your phone from another port.
- Refill fast between outages. With 100W input, both go from empty to full in about 2 hours or less. That matters when power returns for a short window.
- You can see what's happening. Both have a digital display showing remaining battery and charging status, so there is no guessing from four dots.
- Flight-friendly. Both sit under the 100Wh carry-on limit. Pack them in hand luggage and check your airline's rules.
- Genuine, authorised sources with local warranty. Buy from the official channels below and you get real cells and real after-sales support, which matters when 100W is flowing into a laptop worth KSh 100,000+.
Which one should you buy?
Choose the Anker Zolo 25K 165W if you:
- Charge several devices at once (laptop, phone, tablet, earbuds)
- Always forget or lose charging cables
- Carry two high-power USB-C devices, like a laptop and an iPad Pro
- Want the longer 18-month warranty and the option to walk into a Nairobi CBD shop for support
Choose the oraimo PowerJet 130 if you:
- Want the most battery for the lowest price
- Mainly need one laptop plus one phone kept alive through blackouts
- Need the fastest turnaround when power comes back
- Also charge smartwatches or earbuds and want the low-current mode
Students and budget-conscious remote workers will usually be happiest with the PowerJet 130. Consultants, creators and frequent travellers who live out of one bag will get more from the Zolo.
