RYOBI PCL811B review: a quiet 18V ONE+ bedroom fan for summer outages

This is a research-based review, based on manufacturer specs and published data. We do not test products. Figures come from RYOBI's PCL811B product page and spec listing, checked November 1, 2026, and from the CDC and NFPA sources cited below.

The PCL811B is a 7.5-inch fan in RYOBI's WHISPER SERIES, which RYOBI describes as its quietest range of products. It runs on any RYOBI 18V ONE+ battery or plugs into an extension cord. RYOBI lists three speeds of 930, 1,500 and 1,850 RPM, a 160° pivoting head, an integrated handle and hanging options. RYOBI claims it is 44% quieter with 24% greater air velocity, without naming the comparison model on the page we checked.

In a power outage the fan's job is simple: keep air moving over a sleeper so sweat can evaporate, using as little battery as possible. RYOBI does not publish a runtime, so this review estimates one from battery energy with clearly labeled assumptions.

Who should buy it

• Households already on RYOBI 18V ONE+, one of the most common home tool platforms.
• Light sleepers who want a fan marketed for low noise, placed on a nightstand rather than a jobsite floor.
• People who want one fan for both seasons: battery during an outage, extension cord the rest of the year.
• Buyers new to the platform who can choose the PCL811K1 kit, which adds a 4Ah battery and charger.

Who should skip it

• Anyone who wants a stated runtime before buying. Milwaukee publishes one for the M18 Jobsite Fan; RYOBI does not.
• People cooling a large room or garage. A 7.5-inch fan suits one person or a bed; RYOBI lists no CFM.
• Anyone without RYOBI batteries who does not want to buy into the platform. The Treva 10" Fin Fan runs on D cells.

Strengths

• Marketed for low noise. RYOBI places it in the WHISPER SERIES, its quietest range.
• Hybrid power. Any 18V ONE+ battery, or an extension cord to a wall outlet or a power station.
• Three defined speeds. 930, 1,500 and 1,850 RPM, so you can pick low for sleep and save battery.
• 160° pivoting head plus a handle and hanging options for a headboard, hook or shelf.
• Kit option. The PCL811K1 includes a 4Ah battery and charger for buyers starting from zero.

Drawbacks

• No runtime figure. RYOBI shows a runtime chart image but no figure in its page text, and our listing data has none.
• No CFM rating. RYOBI gives a relative air-velocity claim, not an airflow number.
• Small fan. 7.5 inches moves air over a person, not across a room.
• Tool only unless you buy the kit.

How it compares

The RYOBI against the other battery fans we review. Figures are from each maker's page.

Using it in a long outage

Estimating runtime without a maker figure

A RYOBI 18V 4Ah battery stores about 72 Wh (18 V × 4 Ah). We cannot quote RYOBI's own runtime, so use a comparable fan as a guide. Milwaukee's figures for its larger M18 fan work out to roughly 5 W on low (90 Wh over 17 hours). A smaller 7.5-inch fan on low should draw in that range or less. At 5 W, a 4Ah pack would last on the order of 14 hours on low (our estimate, not RYOBI's). On high, plan for a fraction of that. Run the fan on low through one full night at home before an outage, and note how much battery is left.

Corded use from a power station

The extension cord option is the reason this fan earns a place in an outage kit. If you run a power station for the refrigerator, plug the fan in through a short extension cord at night and keep tool batteries charged for the next day. A fan is a tiny load next to a fridge. For sizing a station around both, see best power station for a refrigerator.

A bedroom setup

1. 01Charge at least two 18V ONE+ packs before storm season.
2. 02Place the fan two to three feet from the bed, aimed across your body rather than straight at your face.
3. 03Use low speed for sleep. Switch to medium only when the room is warm and still.
4. 04Open a window on the cooler side of the house at night if outdoor air is cooler and safe to let in.
5. 05Swap and recharge packs each morning from a power station or car charger.

NFPA advises using batteries and chargers listed by a nationally recognized safety lab, not continuing to charge once a battery is full, and stopping use of a damaged battery. Charge ONE+ packs on the RYOBI charger on a hard surface, not on bedding.
