Quick Compatibility Check
- 1 Running headroom: target 1601W; generator provides 800W.
- 2 Surge headroom: target 4803W; generator provides 1600W.
- 3 Result: pick a higher-output unit for safe operation.
What To Do Instead
- 1 Underpowered: The Shop Vac (Wet/Dry, 5-6 HP Peak) needs 1601W running / 4803W surge (with 15% buffer). The RIVER 2 Pro provides 800W / 1600W.
- 2 Safe target: Look for a power station with at least 1601W continuous and 4803W surge at 120V.
- 3 Compatible alternative: The Explorer 2000 Plus (3000W / 6000W surge) clears this device's requirements.
Model-Specific Results
0 of 3 models are SAFE or TIGHT. Most demanding model: Shop-Vac SVX2 (12-Gal, 5.5 HP Peak) (4,176W surge).
| Model | Running | Surge | Verdict | Runtime | Source |
|---|---|---|---|---|---|
| DeWalt DXV10P (10-Gal, 5.5 HP, 2-Stage Quiet) | 1,200W | 3,600W | Fail | — | Engineering Est. |
Show expert analysisTechnical: **Running load:** 1200W from OEM nameplate (10A × 120V). **Estimated startup surge:** 3600W at 3x running (motor-load multiplier — no OEM starting watts published). **Voltage:** 120V AC. 2-stage motor, 90 CFM airflow, 73 dB noise rating — quietest in this set. Field note: The DXV10P is the most power-station-friendly shop vac in this set. At 1200W running and an estimated 3600W surge, it works with most power stations rated 2000W+ with adequate surge capacity. The 2-stage motor runs quieter (73 dB) and may have lower actual inrush than single-stage models, though no OEM data confirms this. Can a portable power station run the DeWalt DXV10P? Only if your power source can supply at least 1200W continuous and approximately 3600W surge at 120V. The motor startup surge is the main challenge, not the running watts. | |||||
| Vacmaster Beast VFB511B (5-Gal, 6 HP Peak, Compact) | 1,320W | 3,960W | Fail | — | Engineering Est. |
Show expert analysisTechnical: **Running load:** 1320W from OEM specs (11A × 120V). **Estimated startup surge:** 3960W at 3x running (motor-load multiplier — no OEM starting watts published). **Voltage:** 120V AC. Single-stage motor, 102 CFM airflow, 320 Air Watts, 82 in. water lift. Field note: The Beast packs the most suction power per pound in this set — 102 CFM from a 12 lb unit. At 1320W running it draws 10% more than the DeWalt but delivers 13% more airflow. The compact 5-gallon tank makes it portable but limits continuous use on large jobs. Is the Vacmaster Beast harder to run on a power station than the DeWalt? Slightly — 1320W versus 1200W running, with an estimated 3960W versus 3600W surge. Both need a power station with at least 2000W continuous and 4000W+ surge for reliable startup. | |||||
| Shop-Vac SVX2 (12-Gal, 5.5 HP Peak) | 1,392W | 4,176W | Fail | — | Engineering Est. |
Show expert analysisTechnical: **Running load:** 1392W from OEM specs (11.6A × 120V). **Estimated startup surge:** 4176W at 3x running (motor-load multiplier — no OEM starting watts published). **Voltage:** 120V AC. SVX2 motor, 12-gallon tank — the highest-draw unit in this set. Field note: The SVX2 draws the most power in this set at 11.6A. Its estimated 4176W startup surge puts it beyond most mid-range power stations. If you need a shop vac specifically for portable power use, the 10A DeWalt is a safer choice. The SVX2 is best paired with stations rated 2500W+ continuous with 5000W surge. Why does the Shop-Vac draw more than the 6 HP Vacmaster? Peak HP is a marketing metric, not an electrical measurement. The SVX2 at 11.6A draws more real power than the 6 HP Beast at 11A. Always check nameplate amps, not HP ratings, for power station sizing. | |||||

Generator Insights
The 1600W surge rating can handle typical motor startup events found in residential compressor-based appliances like refrigerators and well pumps. The 800W running capacity can support continuous loads such as home network equipment, lighting circuits, and small kitchen appliances. This configuration works well for targeted backup scenarios rather than whole-home replacement power.
This unit uses LFP chemistry, which offers stable thermal characteristics during discharge cycles. The 768Wh capacity supports extended runtime for moderate household loads. Source: EcoFlow RIVER 2 Pro User Manual v1.0 (manufacturer documentation).
Technical Analysis
Spec-Based • No GuaranteesTechnical Breakdown
Running range: 1200W (10A) to 1392W (11.6A) depending on motor size. Estimated surge range: 3600W to 4176W at 3x running (motor-load multiplier — no shop vac manufacturer publishes starting watts). Voltage: 120V AC for all residential models.
Expected Behavior
Shop vacs draw near-maximum rated power continuously while running. Unlike power tools that cycle between cuts, a shop vac runs steady until you release the trigger or switch. At 1 hour daily use, energy consumption ranges from 1200 to 1392 Wh.
Field Note
Peak HP is meaningless for power station sizing — a '6 HP' vac may draw less amps than a '5.5 HP' model. Always check the nameplate amperage. Motor startup surge is the primary compatibility concern: a shop vac that draws 1200W running may need 3600W briefly at startup. Size for surge capacity first.
Frequently Asked Questions
Can the EcoFlow RIVER 2 Pro power a Shop Vac?
No. The EcoFlow RIVER 2 Pro falls short on both running (800W offered vs 1601W needed) and surge (1600W offered vs 4803W needed). Safe targets include a 15% buffer for the Shop Vac (Wet/Dry, 5-6 HP Peak)'s motor load profile.
How long will the RIVER 2 Pro run a Shop Vac?
No reliable runtime estimate — this pairing is not compatible. The EcoFlow RIVER 2 Pro cannot safely power the Shop Vac (Wet/Dry, 5-6 HP Peak). See compatible alternatives above for power stations that meet this device's requirements.
Power Tip: To get the most out of your RIVER 2 Pro, keep it in a well-ventilated area. Extreme temperatures can slightly reduce the efficiency of the LFP/NMC cells.
