I’ve at all times 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 useful. However the considered 3D designing a correct housing at all times held me again. Apparently, DarwinFPV had the identical concept—they usually beat me to it. Enter the DarwinFPV Turbo Fan, a purpose-built, ready-to-use answer 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’ll be able to decide up the DarwinFPV Turbo Fan at:
A number of colour 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 instantly by a normal FPV drone LiPo battery (4S or 6S). DarwinFPV claims it might 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 admittedly easy—only a motor, prop, ESC, and a 3D-printed ergonomic housing.
Plug in a battery into the XT60 connector, and it powers on robotically (there’s no on/off swap). You’ll hear the acquainted ESC initialization beeps similar to plugging in an FPV drone.
You’ll be able to safe the battery with a strap utilizing the supplied slots. The ESC is rated for 80A steady and 120A burst, which presents a beneficiant security margin.
A variable-speed set off permits you to management the fan’s output—the extra you squeeze, the sooner it spins.
It additionally options an LED ring across the nozzle, which will get brighter as you enhance 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 elevate eyebrows, it’s clear DarwinFPV put numerous effort into the design and execution. Positive, you would cobble collectively one thing comparable if you have already got the elements, however for most individuals, shopping for a well-designed, totally useful 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, 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—drawing virtually 8A at 25.2V, so I’m sure the fan is far more highly effective than that. In accordance with DarwinFPV, the fan can pull as much as 40A at 6S (1000W), which is nicely throughout the ESC’s limits by the way in which (at 80A). Nonetheless, you’ll want a stable battery—not less than 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 severe thrust in a compact kind issue.
Potential Functions
So what can you employ this fan for? Surprisingly, rather a lot:
- Utilizing it similar to a leaf blower – blow issues off any floor, like leaves off your driveway, or water/snow off your automotive windshield.
- BBQing– it’s unbelievable for getting coals going rapidly
- PC cleansing – way more highly effective than canned air, although it lacks a targeted nozzle for exact utility
- For FPV pilots, you should utilize it for clearing any particles off the bottom earlier than takeoff.
Urged Enhancements
The DarwinFPV Turbo Fan is a fairly intelligent concept, however there’s room to make it even higher:
- Pace 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 enable for precision airflow—preferrred for cleansing electronics.
Remaining Ideas
The DarwinFPV Turbo Fan is an fascinating gadget. It’s a bit dear for what it’s, however for many who want a robust fan for no matter purpose, now you can purchase it off the shelf.
