Model-Specific Results
3 of 3 models are SAFE or TIGHT. Most demanding model: Lasko B20200 (20-inch Box Fan) (166W surge).
| Model | Running | Surge | Verdict | Runtime | Source |
|---|---|---|---|---|---|
| Lasko B20200 (20-inch Box Fan) | 83W | 166W | Safe | ~6.5h | Engineering Est. |
Show expert analysisTechnical: **Running load:** 83 W. **Surge:** 166 W (estimated 2x startup for shaded-pole motor). **Voltage:** 120 V AC. Small shaded-pole fan motors produce a brief inrush at startup that is typically 2x running — far less than the 3x NEC standard for larger motors. Field note: Box fans are among the easiest appliances to run off-grid. Even with the 2x startup surge, any power station rated 200W+ handles this fan comfortably. Will this fan drain my power station quickly? At 83W continuous, an 8-hour overnight run consumes ~664 Wh. A 1000Wh power station handles it with margin to spare. | |||||
| Lasko B20500 (20-inch Box Fan) | 72W | 144W | Safe | ~7.5h | Engineering Est. |
Show expert analysisTechnical: **Running load:** 72 W. **Surge:** 144 W (estimated 2x startup). **Voltage:** 120 V AC. Slightly lower draw than the B20200 — same motor technology, lower speed setting or blade design. Field note: At 72W, this is the lightest box fan in the comparison. Perfect for overnight use on a portable power station — a 500Wh unit runs it for nearly 7 hours. Can I run this fan overnight on a 500 Wh power station? Close — 8 hours at 72W needs 576 Wh. With inverter losses (~70% usable), a 500Wh station runs it for about 5 hours. A 750Wh+ station covers a full night. | |||||
| Lasko 3733 (20-inch Box Fan) | 80W | 160W | Safe | ~6.7h | Engineering Est. |
Show expert analysisTechnical: **Running load:** 80 W (high speed, top of 50-80W range). **Surge:** 160 W (estimated 2x startup). **Voltage:** 120 V AC. Variable speed range means actual draw depends on setting — low speed draws as little as 50W. Field note: If running on battery, use a lower speed setting. Dropping from high (80W) to low (50W) extends runtime by 60% — a meaningful difference on a single charge. How long can I run this fan on low speed? At 50W on low speed, a 1000Wh power station (700Wh usable) runs it for about 14 hours. High speed (80W) cuts that to about 9 hours. | |||||

Before You Buy: Connection Check
Installation warning
These systems are often hardwired to a home panel. To run them from a portable station, you may need a transfer switch installed by an electrician. You cannot just plug it in.

Generator Insights
The 1600W surge rating can support startup sequences for refrigerator compressors, well pumps, and similar inductive motor loads that draw 25 to 33 percent over running current during initial engagement. Once running, the 1200W continuous output can handle typical kitchen appliances, electronics, and power tools within rated limits. This combination addresses both inrush events and sustained runtime needs in backup scenarios.
This unit uses LFP chemistry, a battery architecture chosen for thermal stability in consumer power stations. The 768Wh capacity and 1200W continuous output allow sustained operation without thermal stress under typical residential loads. Source: Anker SOLIX C800 Plus Tech Specs (manufacturer documentation).

Technical Analysis
Spec-Based • No GuaranteesTechnical Breakdown
Running load: 83 W (worst case). Surge: 166 W (2x startup, small fan motor policy for shaded-pole motors). Voltage: 120 V AC required. Box fans use small shaded-pole motors with a brief 2x inrush at startup — much lower than the 3x NEC standard for larger motors.
Expected Behavior
Estimated runtime: ~6.5h. Draws 72-83W steady depending on model. 8 hours daily operation consumes 576-664 Wh. Startup inrush is brief (<1 second) and typically 2x running.
Field Note
Box fans are ideal off-grid appliances. Low running watts, minimal surge, and long daily use. Size your power station for runtime (capacity in Wh), not wattage — any 200W+ station handles the load.
Frequently Asked Questions
Can the Anker SOLIX C800 Plus power a Box Fan (20-inch)?
Yes. The Anker SOLIX C800 Plus provides 1200W running / 1600W surge. The Box Fan (20-inch) needs 96W / 191W (including 15% buffer). That leaves 1104W of running headroom and 1409W of surge margin.
How long will the SOLIX C800 Plus run a Box Fan (20-inch)?
Approximately 6.5 hours, based on the Box Fan (20-inch)'s 83W draw and the SOLIX C800 Plus's 768Wh capacity (70% usable after real-world losses).
What Else Can You Run?
With 875W allocated to the Box Fan (20-inch), the SOLIX C800 Plus still has ~2W of margin. These devices could run simultaneously:
