HAKOBU-FAN: Cordless DC Remote Control Fan with Mobile Battery Support, Up to 80 Hours Operation, to Launch April 20

Otake Co., Ltd., a seasonal home appliance manufacturer based in Koriyama City, Fukushima Prefecture, is set to launch “HAKOBU-FAN” (model: JF-PDC326FR) on April 20, 2026. This DC full remote control fan can be powered by both PD (Power Delivery) compatible mobile batteries and AC outlets.

When used with a PD-compatible mobile battery (20,000mAh, sold separately), the fan can operate for up to approximately 80 hours on its lowest setting, even in locations without an AC outlet. Despite offering a full range of features including 12 levels of airflow adjustment, 4 levels of oscillation angle adjustment, and full remote control, the unit weighs only 2.3kg. This design proposes a new form of fan that can be comfortably used anywhere in the home, free from the constraints of power outlet locations.

Development Background of “HAKOBU-FAN”

Recognizing the limitation of traditional fans being confined to locations with power outlets, Otake Co., Ltd. embarked on developing a fan that could be used anywhere in the home. The goal was to create a product that could freely bring coolness to any desired spot, from the living room to the bedroom, and even to the washroom or laundry area. This vision led to the birth of HAKOBU-FAN.

The name “HAKOBU-FAN” not only signifies “carrying the fan” but also embodies the idea of “carrying the wind itself.” It allows users to place the fan exactly where they want without worrying about outlet positions, direct the wind to the desired area with adjustable oscillation angles, and control the rhythm of the air movement by adjusting oscillation speed. It truly is a fan that allows users to “carry the wind as they wish.”

This product operates with commercially available PD-compatible mobile batteries (sold separately) rather than an internal rechargeable battery. This approach was adopted for the first time by the company to achieve benefits not found in rechargeable fans, such as lighter weight, longer lifespan, and flexible adjustment of operating time. HAKOBU-FAN can be utilized not only as a fan but also as a circulator or a clothes dryer, making it a versatile unit for various air circulation needs.

Product Features

1. Compatible with both AC Outlets and Mobile Batteries

The fan features a Type-C (PD compatible) port on its base. It can operate with an AC outlet or a PD-compatible mobile battery (sold separately, recommended output of approximately 20W or more). The included 2m cable provides flexibility in placement. The design, which uses commercially available mobile batteries, offers several advantages:

Flexible Operating Time with Battery Replacement: Users can choose smaller batteries for short-term use or larger batteries for extended periods. Continuous use is also possible by swapping batteries.
Lightweight and Compact Body: The absence of an internal battery results in a lightweight design, with the unit weighing only about 2.3kg, making it easy to carry and set up.
Longer Lifespan: Battery degradation does not directly impact the unit’s lifespan, as only the mobile battery needs to be replaced for long-term use, offering a sustainable choice.
Utilizes Smartphone Batteries: Existing PD-compatible mobile batteries for smartphones can be used, minimizing luggage as no dedicated adapter is required.
High Safety: Without an internal battery, the risk of internal ignition or swelling due from long-term storage is low, providing peace of mind for households with children or pets.

The estimated operating times when using mobile batteries (5,000mAh to 20,000mAh) are as follows:

Usage Setting	5,000mAh	10,000mAh	20,000mAh
Level 1 (Weakest)	Approx. 20 hours	Approx. 40 hours	Approx. 80 hours
Level 4	Approx. 8 hours	Approx. 16 hours	Approx. 32 hours
Level 8	Approx. 2.3 hours	Approx. 4.5 hours	Approx. 9 hours
Level 12 (Strongest)	Approx. 1.2 hours	Approx. 2.4 hours	Approx. 4.8 hours
Level 1 + Oscillation	Approx. 9 hours	Approx. 18 hours	Approx. 36 hours

*PD-compatible, 12V output compatible mobile batteries are recommended. Batteries are sold separately. Usage times are estimates and may vary depending on usage conditions. Batteries with only 5V output will limit airflow to level 6 and lock the oscillation function.

2. Precise Airflow and Oscillation Control

Equipped with a DC motor, the fan offers 12 levels of airflow adjustment, along with the following functions:

Horizontal Oscillation: 4 angle settings (60°/90°/120°/180°), 2 speed settings.
Vertical Oscillation: Seamless adjustment from 0° to 90°.
Height Adjustment: 75.2 to 90.2cm (15cm variable range).
Timer: On/Off timer, 1 to 8 hours each.
Remote Control: Includes a remote control with a magnetic storage spot on the back of the main unit.
Other Features: Rhythm mode, sleep mode, automatic off (24H).

3. Lightweight, Compact, and Simple Design

The compact body, weighing only 2.3kg, makes it easy to move between rooms. Its simple matte finish design blends naturally with any interior.

Recommended Usage Scenarios

Relaxation in Living Room/Bedroom: Connect to an outlet for continuous comfort, or use with a battery for easy movement between rooms.
Laundry Space/Washroom: Easily set up with a battery even in areas where outlets are distant.
Drying Laundry: Customize drying styles with 12 levels of airflow combined with oscillation speed and angle adjustments.
Disaster Preparedness/Power Outages: Usable in environments without power when connected to a battery, serving as an emergency backup.
