A phone in Nigeria does the work of a bank, a shop counter and an office, and the grid has no opinion on that. So power banks sell here on daily need rather than on novelty. What separates a batch that clears from a batch that sits is narrower than most buyers expect: real capacity, a display customers believe, and a fast-charge claim that survives someone plugging a phone in at your counter.
Description
Twenty thousand milliamp hours. That is what the label says, and on plenty of the units moving through Computer Village this month the real figure sits somewhere closer to eleven or twelve. One supplier sent us a sample that measured around 11,400 against a printed 20,000 and seemed genuinely puzzled that we minded. Understand that gap before you spend money in this category, because everything else follows from it.
The build in the photograph is the format that has taken over the mid-market. Slim plastic body, mirror face, and a small digital readout giving remaining charge as a percentage instead of four dots that mean whatever the customer decides they mean. That readout does more commercial work than it looks like it should. People distrust power banks because they cannot see inside one, and a number on a screen settles that argument at the counter faster than anything printed on a box.
Fast charging here runs in both directions. The unit refills quickly and it pushes charge into a phone quickly, and the first half of that matters more than sellers usually admit, because a bank that needs six hours on the wall is a bank that gets left at home. About the 120W printed on this class of product: that is a combined ceiling across every port at once, measured under laboratory conditions. One phone will pull a fraction of it. Say so in your own listing. A reseller who parrots the headline figure spends the following quarter on the phone to annoyed customers.
Same housing, two builds, and commercially they are chalk and cheese. The 10,000mAh is a pocket item, cheap to land, and it turns over fast at retail. The 20,000mAh is what corporate gift buyers and traders serving the traveller trade actually reach for, and the margin lives there. Buyers who order both are usually wrong about the split.
Our honest opinion, if you have no data of your own yet: weight roughly two thirds of a first order into the 10,000mAh and keep the larger build for people who ask for it by name. Then let the batch correct you.
Specification
These lines decide what actually shows up in the container. Each one gets confirmed against the specific supplier and against a sample that has been in our hands, capacity first, because that is the figure most freely invented at the factory gate.
| Capacity | 10,000mAh and 20,000mAh builds in the same housing. Real cell capacity is verified on the sample and never taken from the label. |
|---|---|
| Maximum output | Up to 120W across all ports combined under ideal conditions. A single device draws far less, so quote it honestly. |
| Fast charge | Two-way quick charge. The unit refills fast and delivers fast, which is the practical selling point. |
| Display | Digital LED readout showing remaining charge as a percentage. This is the feature that closes the sale at retail. |
| Output ports | USB-A output as standard. Type-C output available on some builds, so confirm it if your market expects it. |
| Input | USB input as standard, Type-C on the newer builds. Say which one you want; your customer will notice the difference. |
| Cell type | Lithium. Cell grade differs between suppliers far more than the housing does, and it is the main thing we check. |
| Shell | Plastic with a mirror-surface face. It shows fingerprints; a matte variant is available if that matters to you. |
| Colours | White and black are the standard runs. Other colours are possible at higher volume. |
| Branding | Logo printing on the body face from the minimum. Custom colour boxes from 500 pieces. |
| Certification | CE and RoHS standard, with PSE available. SONCAP is handled separately; see the notice below. |
We do not publish prices, because the landed figure depends on the specification, the Customs valuation and the exchange rate on the day you pay.
Minimum order
The floor is 50 pieces across a shipment. That counts the whole order together, so some 10,000mAh in white and some 20,000mAh in black still make up one fifty between them. Cross 100 and the unit cost drops noticeably, because the battery documentation, the certification file and the freight overhead all spread across more units. On this product that spreading is the biggest single saving available to you, larger than anything you will squeeze out of a factory on the unit price itself. Branded printed packaging pushes the sensible floor up toward 100 for the same reason.
Lead time. Roughly three weeks in production for a standard run, four to five with branding or a colour outside white and black. Then sea freight to Lagos and clearing. Ask us for the SONCAP window as a separate figure; it runs in parallel, but it is worth seeing on paper.
What decides the right one
Start with the number fifty, because that is the one people query first.
A lithium product carries fixed costs a carton of slippers does not. Battery test documentation, compliant packing, a certification file, plus the freight and clearing overhead that attaches to any consignment however small. Those costs barely move between ten units and a hundred. Ship ten and they swallow the margin whole. Somewhere around fifty the arithmetic turns, and by a hundred it is comfortable. Ask for branded printed packaging and the sensible floor drifts up toward that hundred, because the box factory has a minimum of its own and will not budge on it.
Work backwards from that and the rest of how this page is built makes sense. Venocipal sources to order. Nothing here sits on a shelf in Ibadan waiting for a buyer. This particular bank is photographed and written up because it is far quicker to point at an object and say yes or no than to trade paragraphs about port layouts and shell finishes. Say no and tell us what is wrong with it. That no is worth more to us than a vague yes.
Capacity, ports, finish, colour, branding: all of it settled at quoting stage, because a trader in Computer Village selling to walk-in customers and a company ordering two hundred units for conference bags want visibly different things out of the same tooling. You show us. We find who makes it, check whether the specification survives contact with reality, and price it landed.
Common questions
How small an order will you take?
Fifty pieces, counted across the shipment as a whole. Ten thousand and twenty thousand in the same consignment still add up together toward that fifty.
Is the printed capacity real?
Often it isn't. This is the most inflated number in consumer electronics and the factories know exactly what they're doing. We measure it on the sample and quote you what we measured. Better that disappoints you now than after 200 pieces are already on a ship.
Does it actually do 120 watts?
That's a combined ceiling across all ports under ideal conditions. A single phone draws nowhere near it. Sell the speed, keep the wattage figure out of your marketing, and your return rate stays boring.
Which capacity should I lead with?
Retail counter, weight it toward 10,000mAh. Corporate gifting, or traders serving travellers and long-distance market runs, weight it toward 20,000mAh. Genuinely unsure? Split it at the minimum and read what the first batch tells you.
Can my logo go on it?
On the body face, from fifty pieces upward. Custom printed colour boxes are a 500-piece job, which is usually where the branding budget goes if you're doing conference giveaways.

Then describe it, or send the picture. Built-in cables, solar tops, higher capacities, the chunky ones with an LED torch on the side. Ours is on the page to give you something to point at. Point at something else and we'll go hunting for that one instead.

Folding Solar Camping Lanterns
Four hinged panels open out into something bright enough to light a whole room, then fold back into a block that fits in a market bag. Wall charge, USB charge, and a small panel on the body for topping up in the sun. Demand for these holds steady right through the year in Nigeria, and you can probably guess why.

Rechargeable Solar and USB Standing Fans
Heat doesn't check whether NEPA is up. The hours a fan matters most, late afternoon and right through the night, are the hours the grid is least dependable, which is why households buy these without needing much persuading. This particular build does two things that lift it clear of the cheap end of the market: the column adjusts, and it takes a top-up from a small solar panel as well as from a cable.

LED Display Wireless Earbuds
Earbuds move faster than anything else small we ship into Nigeria, and sound quality has very little to do with why. They're cheap enough to be an impulse buy, visible enough to be a status item, and lost or broken often enough that whoever bought from you in March turns up again in September. The build here is the one selling hardest at the moment: a charging case with a battery percentage screen on the front.

Give us a capacity and a number
If this one works for you, tell us which capacity, how many, and whether your name goes on the face. If it doesn't, send a picture of the one that does. Any listing, any shop window, any photo a customer forwarded you asking whether you can get it. We'll track down who builds it, put the real capacity on paper, and quote you landed in Lagos. There's no charge for that and nothing attached to it. Come in under fifty and we'll say so plainly rather than take your deposit and let you find out later.
