CIO Inc., the Osaka-based maker best known for chargers and mobile batteries, has unveiled its very first handheld fan, the CIO Handy Fan[1]. The project went live on the Japanese crowdfunding service Makuake at 12:25 JST on May 11, 2026, and pulled in 1,416 backers and 11,898,960 yen in pledges almost immediately after launch[1]. A single unit doubles as a handheld fan, neck fan, and desktop fan, and the lower section of the body works as a detachable 3,500 mAh power bank[1][2].

A three-in-one fan with dual blades and a charging dock

The CIO Handy Fan covers three usage styles in one body: held in the hand, hung from the neck with a strap, or set onto the bundled charging dock as a desktop fan[1]. The fan head tilts up to 90°, so it can still aim air at the face or neck when worn around the neck[1]. To switch to desktop mode the user simply bends the neck 90° and drops the unit onto the dock; a button on the dock then drives an oscillation pattern spanning 120° total left and right[1].

For airflow, CIO went with two counter-rotating blades on the front and back of the head[1]. The rear blade pulls air in while the front blade pushes it out, a layout the company says lets the fan deliver more wind with less noise[1]. Wind speed is adjustable across four levels, and an LED display shows the current operating mode at a glance[1].

Peltier cooling and full pass-through charging

A Peltier element sits at the center of the fan head, giving the unit a "Peltier cooling" mode that feels like an ice pack when held against the neck or wrists[1]. CIO claims the cooling is strong enough to form condensation on the surface, and the idea is to combine that direct contact chill with the airflow for a lower perceived temperature[1]. The company is careful to note that the Peltier mode does not produce cold air; the cooling effect only kicks in once the surface touches skin[1].

The charging dock uses pogo pins, so the fan starts charging the moment it is dropped onto the base[1]. Once the internal cell is full, the unit automatically switches to a "full pass-through charging" mode that routes power straight to the fan's DC circuit, easing the load on the battery during extended desktop use[1]. Being able to keep the fan running while it charges directly addresses one of the most common complaints about handheld fans, which is that they tend to be unusable while plugged in[1][2].

Doubles as a 3,500 mAh mobile battery

The handle section of the body is a detachable 3,500 mAh mobile battery, released by a button above the LED light[1]. The battery has a retractable USB-C connector tucked inside it, so it can power smartphones and other devices without needing a separate cable[1]. The USB-C tip is held in place by a system CIO calls "Mag-Snap Connect," allowing the connector itself to be swapped out if it ever breaks[1].

The battery section can also be hot-swapped with an optional spare battery, which extends runtime for longer trips outside[1]. The fan body and battery lock together with two hooks plus magnets, a design CIO says will not come apart even when shaken or held upside down[1]. On the safety side, the unit is designed to automatically throttle output when internal temperature rises above a threshold, holding back risk before any heat buildup becomes a problem[1].

Pricing is set at a planned retail of 9,980 yen including tax and shipping, with the Makuake project offering a 17 % early-bird tier at 8,280 yen[1]. The deeper 25 % "super-super early" tier at 7,480 yen and the 20 % "super early" tier at 7,980 yen have both already sold out[1]. The fan comes in black and white, with shipping scheduled for the end of June 2026 and the Makuake project closing on June 9, 2026 at 22:00 JST[1].

Summary

The CIO Handy Fan packs dual-blade airflow, Peltier contact cooling, a 3,500 mAh detachable mobile battery, and a pogo-pin dock with full pass-through charging into a single device[1]. Squeezing all of that into a planned 9,980 yen retail tier and pushing the idea that the unit can still be useful after summer ends is a take on the handheld fan that feels distinctly like a CIO charger-maker product[1][2].
