Neck fans
Neck Fan Runtime
One number, three to five speeds, and no listing that connects them.
No orbit on this page
Only 1 of the 8 listings in this category states a runtime figure. One value is not a comparison, so the orbit is not drawn here.
- Stated range
- 20 hours, stated once
- Listings with a figure
- 1 of 8
Every figure on this page is the manufacturer’s own stated number, produced under conditions the manufacturer chose and usually does not describe. Nothing here was measured by this site.
What the figure measures
A fan runtime is the only figure in this catalog that describes a motor. A motor draws roughly in proportion to how hard it is working, so the same cell can produce a short afternoon or most of a day depending on one switch position.
Which means a single stated figure has to belong to a single speed. Every listing here that quotes hours quotes one figure and states three, four or five speeds, and not one of them says which speed the figure came from.
Capacity, quoted in mAh, is the other number these listings like. It is a tank size. Without a stated draw it converts to no hours at all.
What shortens it
- A higher speed setting, which is the dominant factor and the one the listings never pin down.
- Hot weather, which is the only condition anyone uses one of these in.
- Hair, clothing or a hood partly blocking the intake, which makes the motor work against a restriction.
- Age of the cell, which on a device charged daily through a summer adds up quickly.
What the listing does not say
- Which speed the stated figure belongs to.
- What the figure is at the top speed, which is the setting people actually reach for.
- Whether the stated capacity and the stated runtime were measured on the same unit.
And the fee side
No neck fan listing in this catalog names an app, an account or a fee of any kind. This is the one category where the cost of keeping it working really is just a cable.
