Handheld Fan with Rechargeable Battery and 6 Speed Settings, Foldable for Hand and Desk, Digital Display

The train platform in August, where the air is still and the train is ten minutes late – when paper fans tire your arm after two minutes and cheap handheld fans run out after half an hour and only make noise

It's 32 degrees Celsius, the platform has no roof, and there's no air movement between the tracks. A paper fan helps for two minutes, then your arm aches. The fan from the kiosk runs for half an hour, sounding like a hairdryer, and can't be set down anywhere, so it has to be held the whole time. If you're out and about in summer – on a train, in an office without air conditioning, in a festival tent, at a desk in the attic – you need a device that runs for a long time, is quiet enough for an indoor space, and can be set down when both hands are needed. This handheld fan combines a 5000 mAh battery, six speed settings, and a folding joint that turns it from a handheld to a desktop device.

What makes this handheld fan different

• Folding joint between head and handle – the fan head can be angled so that the device stands on its own on a desk, a folding table on a train, or a bedside table; this means it doesn't have to be held the whole time, and your hands are free for a book, keyboard, or coffee.
• 5000 mAh battery – the capacity is significantly higher than that of simpler handheld fans with 1200 to 2000 mAh, which is why the device lasts a whole day of travel instead of running out after the first transfer.
• Six speed settings instead of three – the finer graduation allows for a setting that remains quiet enough for a phone call in the office, and a powerful setting for outdoors; with only three settings, the usable setting is usually exactly in between.
• Digital display for charge status – the remaining battery level is shown as a number, not via two or three light dots; this makes it clear before leaving whether charging is needed, instead of realizing it on the go.
• Circumferential ring on the fan head – the enclosed housing around the impeller bundles the airflow forward instead of letting it escape to the side; therefore, at the same rotational speed, more air reaches where it is needed.
• Eyelets for a carrying strap on the handle – the device can be hung on the wrist or a backpack instead of disappearing into a bag during every break.

Who it's for

For everyone who travels by train, bus, and subway in summer where air conditioning is missing or fails. For commuters on the platform and in traffic jams. For offices and home offices without air conditioning, especially in attics. For festivals, concerts, and open-air events. For city trips, airports, and waiting rooms. For the beach, outdoor pools, and campsites. For outdoor sports events and long waits in the sun. For people who sweat easily and dislike sitting in enclosed spaces in summer. For kitchens and barbecue areas where cooking gets hot. For nail salons, hairdressers, and anyone who professionally works with drying times. For bedrooms on hot nights as a quiet airflow at the bedside table. For stroller walks in midsummer, but only out of reach of the child and never directly attached to the stroller. As a gift for the start of summer, for a holiday trip, or as a practical souvenir. Important note on selection: The manufacturer states a battery capacity of 5000 mAh, but provides no information on the actual runtime per speed setting. As a rule of thumb: At the lowest setting, a device of this size runs many times longer than at the highest – if you want to last all day, plan with the lower settings. Also not specified are charging time, weight, and the connection type of the charging cable. A splash water protection class is not indicated, so the device is intended for dry use and should not be placed by the pool or in the rain.

Charging, adjusting, safe use

Fully charge the fan before first use and watch the display until it reaches full status. Use a 5 V power supply for charging; fast chargers with higher voltage are not intended for small devices of this type. Do not leave the device permanently connected to power overnight once it is full. For handheld use, straighten the head; for tabletop use, angle it until the housing stands securely – otherwise, it will tip over on a tablecloth or uneven surface. Cycle through the speeds using the control button and choose a low setting indoors, as higher settings are clearly audible. Important safety instructions: Do not reach into the rotating impeller with your fingers and operate the device out of reach of small children, as the grid openings are permeable to small fingers. Keep a distance with long hair, scarves, and hoodie strings, as loose ends can get caught in the rotor. Do not operate the fan in a stroller, in bed next to a sleeping child, or in a child's hand. Do not use the device near water, do not operate with wet hands, and do not use it in the rain. Do not leave it in closed vehicles in the sun: Heat permanently damages lithium batteries and can be dangerous in extreme cases. Also, do not place it next to radiators, stoves, or open fires. If there is visible damage to the housing, deformation, or unusual heating during charging, do not continue to use the device. To clean, switch off, keep the charging port dry, and wipe the housing with a lightly dampened cloth. Remove dust between the blades with a dry brush or cotton swab; never rinse with water and do not immerse in liquid. Do not use solvents or alcohol-containing sprays, as they can tarnish plastic housings. For prolonged non-use, such as over winter, store the battery half-charged instead of completely empty, and keep the device dry at room temperature.

For anyone who is out and about in midsummer and doesn't want to wait for the next air-conditioned room.
