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 | ~7.0h | 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 โ 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 | ~8.0h | 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 โ 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 โ a 500Wh unit runs it for nearly 7 hours. Can I run this fan overnight on a 500 Wh power station? Close โ 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 | ~7.2h | 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 โ 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% โ 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. | |||||

The 3000W surge rating handles moderate motor startup loads including sump pumps, refrigerators, and small power tools. At 828Wh base capacity, runtime is limited โ expect 3โ4 hours on a 200W load or about 30 minutes at full 1500W draw. The expandable 1548Wh battery roughly triples runtime. Solar recharging is the main weakness: the 200W / 30V limit means only small, low-voltage portable panels are compatible. Plan for slow solar recovery (4+ hours for a full charge with a compatible 200W panel).
The Jump 1500X uses LiFePO4 chemistry rated for 3,000+ cycles to 80% capacity. The built-in jump starter adds emergency vehicle starting capability not found in competing power stations. LFP chemistry provides thermal stability for the combined power station and jump starter functions. Source: VTOMAN official US product page (manufacturer documentation).

Yes. The VTOMAN Jump 1500X provides 1500W running / 3000W surge. The Box Fan (20-inch) needs 96W / 191W (including 15% buffer). That leaves 1404W of running headroom and 2809W of surge margin.
Approximately 7.0 hours, based on the Box Fan (20-inch)'s 83W draw and the VTOMAN Jump 1500X's 828Wh capacity (70% usable after real-world losses).
With 1115W allocated to the Box Fan (20-inch), the VTOMAN Jump 1500X still has ~2W of margin. These devices could run simultaneously:
Power Tip: To get the most out of your VTOMAN Jump 1500X, keep it in a well-ventilated area. Extreme temperatures can slightly reduce the efficiency of the LFP/NMC cells.
