I’ve all the time had a pile of spare motors and ESCs sitting round, and for the longest time, I toyed with the concept of constructing a handheld fan. It simply appeared like a no brainer venture—easy, enjoyable, and practical. However the considered 3D designing a correct housing all the time held me again. Apparently, DarwinFPV had the identical thought—and so they beat me to it. Enter the DarwinFPV Turbo Fan, a purpose-built, ready-to-use resolution that faucets into the identical elements we use in FPV drones. However is it only a gimmick, or is it genuinely helpful? Let’s dive in.
The place to Purchase
You may choose up the DarwinFPV Turbo Fan at:
A number of shade choices can be found, and it may be bundled with a 6S 1300mAh LiPo battery.
What Is the DarwinFPV Turbo Fan?
In essence, this can be a ducted fan constructed utilizing a brushless motor and propeller inside a 3D-printed housing. It’s powered straight by a normal FPV drone LiPo battery (4S or 6S). DarwinFPV claims it may push as much as 1.3kg of thrust, pulling as much as 1000W of energy—and from my expertise, that quantity appears plausible.

Design & Construct
The fan is de facto easy—only a motor, prop, ESC, and a 3D-printed ergonomic housing.
Plug in a battery into the XT60 connector, and it powers on routinely (there’s no on/off change). You’ll hear the acquainted ESC initialization beeps identical to plugging in an FPV drone.
You may safe the battery with a strap utilizing the supplied slots. The ESC is rated for 80A steady and 120A burst, which provides a beneficiant security margin.
A variable-speed set off permits you to management the fan’s output—the extra you squeeze, the quicker it spins.
It additionally options an LED ring across the nozzle, which will get brighter as you improve throttle.
The nozzle itself is large, much like a hair dryer. So as a substitute of focusing airflow like an air compressor, it capabilities extra like a miniature leaf blower—broad and forceful.
Whereas the worth may increase eyebrows, it’s clear DarwinFPV put quite a lot of effort into the design and execution. Certain, you could possibly cobble collectively one thing related if you have already got the elements, however for most individuals, shopping for a well-designed, absolutely practical unit off the shelf is the higher use of money and time.
Efficiency Testing
As soon as powered by a 4S or 6S LiPo, the fan attracts round 0.02–0.03A of present (even when the motor isn’t spinning), so it’s important to unplug the battery after use to keep away from over-discharging.
When testing the fan, it maxes out my 200W bench energy provide at solely half throttle—drawing virtually 8A at 25.2V, so I’m sure the fan is far more highly effective than that. In line with DarwinFPV, the fan can pull as much as 40A at 6S (1000W), which is properly throughout the ESC’s limits by the way in which (at 80A). Nevertheless, you’ll want a strong battery—at the least a 30C for a 6S 1300mAh pack—to unlock its full potential.
Airflow is spectacular: the fan was in a position to transfer the curtains and leaves on the plant from over 5 meters (15 ft) away. That’s critical thrust in a compact type issue.
Potential Purposes
So what can you employ this fan for? Surprisingly, rather a lot:
- Utilizing it identical to a leaf blower – blow issues off any floor, like leaves off your driveway, or water/snow off your automotive windshield.
- BBQing– it’s improbable for getting coals going rapidly
- PC cleansing – much more highly effective than canned air, although it lacks a centered nozzle for exact software
- For FPV pilots, you should use it for clearing any particles off the bottom earlier than takeoff.
Urged Enhancements
The DarwinFPV Turbo Fan is a reasonably intelligent thought, however there’s room to make it even higher:
- Velocity Ranges: Could be good to have buttons for choosing fixed velocity ranges, particularly for bench use (e.g., as a desktop fan in the summertime, or cooling element throughout testing).
- Adjustable Tilt & Stand: Add a tiltable stand for hands-free operation.
- Battery Voltage Show: A easy voltage readout would assist forestall over-discharge.
- Energy Change: An on/off button is a should for security and battery administration.
- Interchangeable Nozzles: A narrower, detachable nozzle would permit for precision airflow—preferrred for cleansing electronics.
Ultimate Ideas
The DarwinFPV Turbo Fan is an fascinating gadget. It’s a bit dear for what it’s, however for many who want a strong fan for no matter cause, now you can purchase it off the shelf. Whether or not you’re cleansing your PC, blowing mud off your workbench, or simply in search of an excuse to repurpose your drone batteries, this fan delivers highly effective efficiency in a smooth, transportable package deal.
