PASSDevice output type must match generator output.
120V required -> 120V available
Yes - DELTA 2 Max has enough running and surge power for the EV Charger (Level 1, 120V). Target ~1656W running / 1656W surge; the generator provides 2400W / 4800W.

3 of 3 models are SAFE or TIGHT. Most demanding model: Tesla Mobile Connector Gen 2 (NEMA 5-15, 12A) (1,440W surge).
| Model | Running | Surge | Verdict | Runtime | Source |
|---|---|---|---|---|---|
| Tesla Mobile Connector Gen 2 (NEMA 5-15, 12A) | 1,440W | 1,440W | Safe | ~1.0h | OEM Manual |
Show expert analysisTechnical: **Running load:** 1440 W (12A at 120V). **Surge:** 1440 W (no inrush โ EVSE is a pass-through device, not a transformer). **Voltage:** 120 V AC required (NEMA 5-15 outlet). The Mobile Connector simply passes AC power to the vehicle's onboard charger. Field note: Level 1 charging on a portable power station is an emergency-only strategy. At 1440W continuous, even a large 4 kWh station provides under 2 hours of charging (~5 miles of range). Useful for getting to the nearest charging station, not for a full charge. Can I charge my Tesla from a portable power station? Yes, if it delivers 1440W continuous at 120V. But runtime is the real limit โ a 2000Wh station adds only about 2-3 miles of range. Useful in an emergency to reach the nearest Supercharger. | |||||
| Ford Mobile Charger (NEMA 5-15, 12A) | 1,440W | 1,440W | Safe | ~1.0h | OEM Manual |
Show expert analysisTechnical: **Running load:** 1440 W (12A at 120V). **Surge:** 1440 W (pass-through EVSE, no inrush). **Voltage:** 120 V AC required. The Ford Mobile Charger supports both 120V (Level 1) and 240V (Level 2) with different adapters. Field note: The Ford Mobile Charger comes included with F-150 Lightning and Mustang Mach-E. On a portable power station, expect only emergency-level charging โ enough to reach the nearest public charger, not for daily commuting. Can I charge my F-150 Lightning from a portable power station? Yes, at Level 1 (1440W). But the Lightning's 131 kWh battery would take 90+ hours to fully charge at this rate. A power station provides emergency range only โ a few miles per hour of charging. | |||||
| Lectron Level 1 J1772 EVSE (NEMA 5-15, 12A) | 1,440W | 1,440W | Safe | ~1.0h | OEM Verified |
Show expert analysisTechnical: **Running load:** 1440 W (12A at 120V). **Surge:** 1440 W (pass-through EVSE). **Voltage:** 120 V AC required. Universal J1772 connector compatible with all non-Tesla EVs (BMW, Hyundai, Kia, Ford, Chevy, etc.). Tesla owners need a J1772-to-Tesla adapter. Field note: The Lectron is the most versatile option โ J1772 works with nearly every EV in the US except Tesla (which needs an adapter). At $100-150, it's an affordable emergency charging backup to pair with a portable power station. Can I use a portable power station as an emergency EV charger? Yes โ any power station rated 1500W+ continuous at 120V can run a Level 1 EVSE. The limiting factor is battery capacity. A 2000Wh station provides roughly 1 hour of charging, adding 2-5 miles of range. | |||||

The 4800 W surge can support typical startup loads for refrigerators, well pumps, and air compressor motors that require momentary inrush current. The 2048 Wh capacity provides extended runtime for moderate continuous loads. This configuration can handle brief motor starts while sustaining steady power delivery for home backup scenarios.
This unit uses LFP chemistry, which offers a different thermal profile than older lithium chemistries. The manufacturer provides operational guidelines in their documentation.

Yes. The EcoFlow DELTA 2 Max provides 2400W running / 4800W surge. The EV Charger (Level 1, 120V) needs 1656W / 1656W (including 15% buffer). That leaves 744W of running headroom and 3144W of surge margin.
Approximately 1.0 hours, based on the EV Charger (Level 1, 120V)'s 1440W draw and the DELTA 2 Max's 2048Wh capacity (70% usable after real-world losses).
With 470W allocated to the EV Charger (Level 1, 120V), the DELTA 2 Max still has ~10W of margin. These devices could run simultaneously:
Power Tip: To get the most out of your DELTA 2 Max, keep it in a well-ventilated area. Extreme temperatures can slightly reduce the efficiency of the LFP/NMC cells.
