SKIL 12V/20V Brushless 4 in. Clamp Fan, Tool Only- FN0400D-00, One Size, Red

Another home run from Skil and maker Chervon. I was probably the first U.S. shopper to buy this fan. Normally I buy my tools used; it's better for the environment, the domestic economy, and my wallet. But ever since the PWRCORE 12 line was launched, I had been clamoring (in forums and YouTube comments) for Skil to bring us a 12V fan. Skil listened, and I want to reward them and spread the word about this fan to as many buyers as possible, as soon as possible. Another reason I bought it now was that it can use either Skil's 12V battery OR Skil's 20V battery. I don't own any PWRCORE 20 products, just PWRCORE 12 and 40. But unlike, say, the 12V battery or inflator, this would not be a tool that PWOCORE 20 owners would return because they had bought the wrong voltage. I've owned the Milwaukee M18 7-inch fan for about 6 years; I keep it strapped to my Greenworks 21-inch walk-behind mower, where it blows on my neck to keep me cool. As you can see in my first photo, the Skil is slightly wider, slightly larger overall. But in all other respects, the Skil beats the Milwaukee. Compared to the Milwaukee: - The Skil costs considerably less. - The Skil weighs more than a pound less empty; Plus, it can use a lighter (12V) battery. - The Skil blows slightly more air: 500 cubic feet per minute (CFM) vs. 450. - The Skil sounds more pleasant, with less turbulence; think Vornado. - The Skil is quieter at its highest setting--maybe 3 or 4 dB quieter. - The Skil has a brushless motor, so its motor works more efficiently and can be expected to last longer. - The Skil can use either of two nominal battery voltages: 12V (10.8V under load) or 20V (18V under load). - The Skil does not need a proprietary AC adapter to be powered from an AC outlet. Just a 110V-to-USB power supply and a USB-C to USB-C cable (or USB-A to USB-C if you'll settle for about 200 CFM). - The Skil can be powered by a USB power bank, with limitations (discussed later). So how long does it last on one 4-amp-hour PWRCORE 12 battery? I got 2.7 hours at full-blast, 6.2 hours when I set the dial to the final tic mark, the mark found at the 3 o'clock position, which is roughly 60 percent of full power. In other words, reducing full power by 40 percent more than doubles the endurance. A PWRCore 12 4.0AH battery stores about 43 watt-hours of usable energy. At full power then, the Skil 7-inch fan draws about 1.6 amps (43 WH divided by 2.7 hours). At 60 percent power, it draws about 0.7 amp. With 90 watt-hours (18V x 5), a 5AH PWRCore 20 battery holds 2.1 times as much energy as a 4AH PWRCore 12. But a larger battery needn't work as hard to provide the same power. I would expect the 5AH 20V battery to last between 2.2 and 2.4 times as long at a given setting. Speaking of settings: The dial clicks on at the the 9 o'clock position; it reaches full power at 7 o'clock, 10 twelfths around the dial. Oddly, the final white tic mark is at 3 o'clock, so keep turning for maximum coolth. Also, the dial's black-on-black indicator notch is hard to see. I suggest you mark it with a white marker (second photo). I tested the fan's USB-C power capabilities using two power banks (USB-C to USB-C) and one AC-powered USB adapter (USB-C out and USB-A out). To reach full speed through its USB-C, port, the Skil fan appears to rely on the the USB-C protocol called Power Delivery (PD). The protocol provides several profiles to "handshake" at different voltages. I attained full power (16 to 18 watts) from one power bank--a RAVPOWER 15,000mAH. I achieved only 10.5 watts (5V x 2.1 amps) from my other power bank--a Hydeson slim 12,000mAH--and when powered from any power supply, including AC, through a USB-A-to-USB-C cable. My guess: Your power supply will need to support profile 2 (12V@1.5A 10~18W) to provide full power. Profile 3 (12V@3A 36W) should also work, as should Profile 4 (12V/20A@3A 36W ). A 15-volt profile will not. Depite this small limitation, Skil has knocked it out of the park with the 7-inch Multivolt Fan. Like other Skil PWRCore products, it's far better than it has a right to be at its price point. Highly recommended. 2024-07-17 UPDATE: I've bought two more: one for my daughter, a second for me. I took mine to an indoor concert, where it silently kept me cool while other concertgoers were fanning themselves. One suggestion to Skil: Add an LED indicator light to remind me that the fan is on. The fan is so quiet, I sometimes forget to turn it off. I'd pay $3 more for the LED.

I have 2 of these fans. They run a long time on 4 ah battery and have great air flow. Night saver if your power goes out and need some breeze and fan noise!

I already had some SKIL tools with batteries to fit this fan. So it was kind of a no brainer. It does what you would expect a fan to do, move the air around, making your space cooler and more comfortable. It's relatively quiet and efficient. What I like best is the hook that I can attach to the ceiling vent in my travel trailer. Helps keep things cooler in the warm weather.

The USB-C means in a power outage this fan can be plugged in to a power station with the AC inverter off (to save battery life) or it can be powered from a handheld battery. This is the only (legit) worksite fan I've found that uses USB-C as an option. I wish the Flex could use USB-C, shucks. I hooked it to a power station, it uses roughly between 2 and 15 watts (less with an A to C at least on my power stations). I got a second so there is no fan sharing (hurricane season isn't over and these fans should last through many of them, as well as normal worksite use (1 is for my wife at art shows).).

I had returned my first fan due to an annoying ticking sound. This is the second one that I ordered. Evidently the ticking sound is characteristic of this model. Ticking is the same as the first one received from Amazon. However, other than that, I like the Skil quality and decided to keep this one. This fan does a good job of moving air where needed. If not for the ticking sound, I would easily give it 5 stars.

I run this with the 20v batteries and I love the size, the power, and how quiet it is on lower speeds. High speed moves a good amount of air but is noisier. The handle on the top makes it easy to move and it has the hook to hang it. It is variable speed and the brushless makes it run longer on a battery. Overall great purchase.

Using this fan to circulate air in my RV. Works well with my existing 20 volt 4 ah Skil battery. Very quiet on LOW power setting, especially from ~10' away. Uses very little power on LOW, only 1 bar after 10 hours of continuous operation. This will be perfect for running all night! When battery eventually dies, I can still operate fan from RV's USB-C outlet. Brilliant!

Fan works great - variable speed fan motor and long run time.

Mi esposo lo utiliza cuando trabaja en su bodega. Arroja un aire como de un abanico manual, y debe de estar a una cercania de aprox un metro para percibirlo.
