Oraimo’s Nigerian store was selling the Oraimo PowerTurbo folding fan (OPF-502A) for ₦129,000 on October 27, 2026, down from a listed ₦142,000, and its product page promises “up to 22 hours of runtime” from the 4000mAh battery. Read a little further down the same page and the picture changes, because Oraimo also says high speed gives you 3 hours of strong airflow, and the spec list quotes a working time of 2 to 7 hours from its own lab tests.
Those numbers aren’t contradictory so much as measured at different speeds, but they decide whether this fan carries you through a night without light or dies before 2am. With the dry season pushing temperatures up and power cuts still a fact of life in many homes, it’s worth knowing which figure applies to the way you’ll actually use it before you spend six figures on a fan.

The 22-hour figure belongs to the gentlest setting
A fan’s battery life drops sharply as the speed goes up, and the PowerTurbo’s own figures show that range clearly. Oraimo doesn’t say which of the eight speeds produces 22 hours, but it pairs that claim with 3 hours on high, so it’s safe to read 22 hours as the lowest setting. The lab-tested 2 to 7 hours in the spec list is the more useful guide for a hot room, where most people run a fan somewhere in the middle.
Plan around that if you’re buying it for nights without power. Charge it fully while there’s light, start on a medium speed and only step up when the room is unbearable, because a fan that empties itself on high at 11pm leaves you hot for the rest of the night. Oraimo’s spec list rates the fan at 12W while another section of the page calls it an energy-saving 20W fan, and the store doesn’t explain the gap, so the runtime figures are the better yardstick than either wattage.
A basic phone charger puts this fan in slow mode
Oraimo puts a warning in bold on the product page that the fan should be charged with a charger rated at 18W or higher, and its troubleshooting notes show what happens if you don’t. With an adapter that supports 9V 2A or 12V 1.5A, the fan switches to fast charging and its light flashes green, while a plain 5V charger puts it into slow charging mode and the light flashes white. Oraimo doesn’t publish a charging time for either mode, but if you see white, you’re on the slow path.
That matters most when power comes back for only a few hours. Use a fast charger you already own if it supports those voltages, and if the fan switches on and dies straight away, Oraimo’s advice is to charge it for 10 to 15 minutes with a 9V or 12V adapter before trying again, so don’t assume the battery is faulty after one failed start.
A detachable battery is the feature that keeps it useful longer
The battery pack comes out, and Oraimo’s own guidance says that when it reaches the end of its charge cycles, you replace it with a pack of the same capacity and voltage rather than the whole fan, which a fan with a sealed battery can’t offer. The PowerTurbo also folds down to about 150mm and weighs 2.1kg, and it stretches to about 994mm when extended, so it can stand beside a bed or fold away into a bag for a shop or a trip.
If you want longer runtime and don’t need to fold it, Oraimo’s AirCruze 14-inch pedestal fan (OPF-503A) is listed with an 11.1V 4400mAh battery, up to 32 hours of runtime, a remote and four-way oscillation, at ₦145,900. It was marked sold out when we checked, so the PowerTurbo is the one you can actually order from Oraimo today.

Buy it if
- You want a fan that folds away and moves easily between rooms
- You can charge it with an 18W or faster adapter during power windows
- You'll run it on low or medium speed through the night
Skip it if
- You need hours of high-speed airflow on one charge
- You only own a basic 5V phone charger and don't plan to buy a faster one
- You want a remote and oscillation, which the AirCruze lists instead
A well-built portable fan with a replaceable battery, as long as you buy it for low and medium speeds and treat 22 hours as the best case rather than the norm.
Heat is hard on your other gadgets too, and our look at what NiMet’s hotter, dustier forecast means for your phone and laptop covers how to keep them safe this season. For the PowerTurbo itself, the number to remember is 3 hours on high, and if your nights without power run longer than that, buy it knowing you’ll be living on the lower speeds.
