Instructions for âF95Bâ portable rechargeable fan
This fan can be sold in different configurations, and doesnât usually come with an instruction book.âWe experimented with two different items from separate sellers, both marked âF95Bâ:
- One, bought in Hong Kong in 2014, was labelled in Chinese and with a feather logo in the centre and on the battery (an 18mmĂ65mm â18650â-size Li-ion, rated at 2200mAh 3.7V);
- the other, bought online in 2017, was labelled in English, with a snowflake logo in the centre and no logo on the battery.
The fans otherwise looked identical, but the particulars of their operation were different.âI donât know if one manufacturer sells it in different configurations or if others have copied the product.
Very similar-looking fans are sold as âHY96Aâ and as âTaidea UF-TDF01â. We have not tried these but we suspect they are the same.
F95B operation
Short-pressing the right-hand (green) button:
- From the âoffâ state, starts the fan at speed 1. On the Chinese model we tried, speed 1 is the fastest speed.âOn the English model, speed 1 is the slowest speed.
- From speed 1, switches to speed 2 (a medium speed). The English model can also run with the battery removed and only external power connected.âIn this case, only the slow speed 1 and the torch are available, and pressing the green button a second time simply switches off the fan instead of changing to speed 2.
- From speed 2, switches to speed 3 (the slowest speed on the Chinese model, or the fastest speed on the English model). Faster speeds are useful when itâs hotter, but slower speeds run quieter and make the battery last longer.âThe hum frequency of the medium and slow speeds is about 85% and 70%, but Iâm not sure how this translates to air speed or battery life. When the battery is low, the fastest speed can cut off more quicklyâso on the Chinese model (where the fastest speed is selected first), if you have low battery you might want to switch to a slower speed quickly before the fan has finished spinning up.â(You might also want to do this if youâre in a situation where you have to limit the noise.) Such quick changes are not necessary on the English model, but the tradeoff is the fastest speed is slightly more troublesome to reachâperhaps they thought itâll be wanted less frequently if the climates of English-speaking countries are cooler than that of southern China.
- From speed 3, on the Chinese model, switches the fan off and switches on the torch (the torch can then be switched off by pressing either button); on the English model, just switches off the fan.
Long-pressing the right-hand (green) button:
- on the English model, switches the torch on or off.âThis model allows both fan and torch to be running at the same time and switched independently.âLong-press to switch on the torch, then short-press to select a fan speed.
Short-pressing the left-hand (red) button:
- on the Chinese model, switches everything off,
- on the English model, queries the battery level: either 1, 2 or 3 LEDs will briefly light up to indicate how much charge is left in the battery (3 LEDs being highest).âA battery-level query does not seem to be available on the Chinese model.
Long-pressing the left-hand (red) button:
- on the English model, switches everything off.
Charge light:
Lights up red when itâs charging; changes colour when charged:
- on the Chinese model we tried, it changes to green;
- on the English model we tried, it changes to blue.âThe blue lamp is also lit when external power is connected but the battery is missing.
ZS fan
In 2019 we bought (online) a third fan, marked âZSâ, which appears to be a derivative of the F95B. In this version the controls are reduced to one unlabelled button, which cycles through slow-medium-fast-torch-off, and the battery is held in a vertical grasp-handle rather than being horizontally mounted below the fan.âThe unit can still be stood on a table by easing open a clip at the top front of the handle which then allows the handle to flip around to the back of the blades.âAgain no instructions were provided.
I suspect the ZS uses a version of the two-button F95Bâs circuit and they simply havenât connected the red-button input.âIt was sold without battery, and in that state its âfastâ speed was reduced to âmedium-slowâ to run on external power, but we had a spare 18650 we could fit to restore normal operation.
We still donât know who made it.âIt came in a box claiming (among other things) the fan is safe for babies, whereas a label on the fan itself said it isnât, so it seems to have been irresponsibly repackaged.âA search for the exact words of that box (which had 24 English mistakes) found a lady in Guangdong promising to ship 20,000 per day but not stating their source; a search for the fanâs own label found only resellers.
