1 of 3 models are SAFE or TIGHT. Most demanding model: Wayne CDU800 (1/2 HP) (3,381W surge).
| Model | Running | Surge | Verdict | Runtime | Source |
|---|---|---|---|---|---|
| Zoeller M98 Flow-Mate (1/2 HP) | 1,081W | 3,243W | Soft Start | ~0.5h | NEC Standard |
Show expert analysisTechnical: **Running load:** 1,081W (115V x 9.4A OEM rated). **Surge:** 3,243W at motor startup (3x NEC estimate). **Voltage:** 120V AC. The cast iron PSC motor draws heavy inrush current on every pump cycle. Field note: The Zoeller M98 is the industry reference in cast iron sump pumps. Its PSC motor has no built-in soft-start โ the full inrush hits the power station instantly. An external soft-start device can reduce this surge, but size the inverter for the full 3,243W if running without one. Can I run a Zoeller M98 sump pump on a portable power station during a flood? Only if your power source can supply at least 1,081W continuous and 3,243W surge at 120V. The PSC motor creates a hard startup spike that will trip undersized inverters. | |||||
| Wayne CDU800 (1/2 HP) | 1,127W | 3,381W | Soft Start | ~0.5h | NEC Standard |
Show expert analysisTechnical: **Running load:** 1,127W (NEC 430.248 rated). **Surge:** 3,381W at motor startup (3x NEC estimate). **Voltage:** 120V AC. The coated steel PSC motor draws the highest inrush in this class due to its conservative NEC-rated amperage. Field note: The Wayne CDU800 is the Home Depot best-seller for suburban basements. Without OEM amperage data, specs are derived from NEC tables โ the actual draw may be slightly lower, but sizing to NEC ensures safe headroom. Can I keep my Wayne sump pump running on battery backup during a storm? Only if your power source can supply at least 1,127W continuous and 3,381W surge at 120V. The motor startup surge is the critical factor โ most small power stations cannot handle it. | |||||
| Liberty Pumps 287 VMF (1/2 HP) | 920W | 2,645W | Tight | ~0.6h | OEM Manual |
Show expert analysisTechnical: **Running load:** 920W (115V x 8.0A OEM rated). **Surge:** 2,645W at motor startup (115V x 23A LRA, OEM verified). **Voltage:** 120V AC. The 3450 RPM PSC motor with OEM-documented LRA provides the most precise surge data in this class. Field note: The Liberty 287 is the plumber's choice and the most battery-friendly 1/2 HP sump pump in this comparison. With OEM-verified LRA data, the 2,645W surge is a confirmed number โ not an estimate. A 3,000W power station can handle this reliably. Is the Liberty 287 easier to run on a power station than other sump pumps? Only if your power source can supply at least 920W continuous and 2,645W surge at 120V. Its OEM-documented 23A locked rotor current is lower than NEC estimates for competing 1/2 HP pumps, making it more generator-friendly. | |||||
This unit is borderline without mitigation; 17 of 33 generators meet SAFE/TIGHT margins for this device.
17 of 33 generators are SAFE+TIGHT for Sump Pump (1/2 HP).

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.

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).

It depends on the model. 1 of 3 Sump Pump (1/2 HP) models are compatible with the VTOMAN Jump 1500X. See the model-specific results table for exact verdicts per model.
It depends on the model. Compatible models run approximately 0.5โ0.6 hours on the VTOMAN Jump 1500X. 0 of 3 models are not compatible. See the model-specific results for details.
With 70W allocated to the Sump Pump (1/2 HP), the VTOMAN Jump 1500X still has ~3W of margin. These devices could run simultaneously:
Storm Safety: Since the Sump Pump (1/2 HP) is critical for preventing flooding, we recommend testing this setup specifically before the storm season. Ensure the VTOMAN Jump 1500X is fully charged to 100% as storms approach.
