Can the EcoFlow Delta 3 Max Run a Washing Machine?

I plugged my full-size Samsung washer straight into the EcoFlow Delta 3 Max and ran a regular cycle with a full load. The battery went from 53% to 47% — about 6% of the pack, or roughly 123 Wh — over a wash, rinse and spin that took about 1 hour 8 minutes. That left plenty of capacity for lights, a fridge or charging phones during an outage.

Can the EcoFlow Delta 3 Max run a washing machine? Yes. In my test it handled a full-size 120V top-load washer with room to spare. Below are the exact readings from the video, what the wattage looked like through the cycle, and how many similar loads you could expect from a full charge.

How I Set Up the Test

The washer in this video is my Samsung High-Efficiency Impeller Extra-Large 5.2 cu ft top-load in Brushed Black. The rating plate on the machine reads model WA52A5500AV, 120V / 60Hz. I plugged it directly into one of the Delta 3 Max AC outlets — no extension cord tricks, no special adapter — added laundry pods, loaded a full set of clothes and selected a regular wash cycle.

If you are shopping for a similar top-load setup and want something a bit smaller than my 5.2 cu ft unit, this Samsung 4.7 cu ft top-load washer and electric dryer bundle is a practical Amazon option. The washer in that bundle is 4.7 cu ft, so it is a smaller tub than the one I tested.

Before I hit Start, the Delta 3 Max sat at 53%. The station’s 2,048Wh LiFePO4 pack and 2,400W inverter are well above what a typical 120V residential washer needs, so the question was never “will it turn on?” — it was “how much battery does one real load take?”

What the Washer Drew Through the Cycle

Washer power is not a flat number. Fill, tumble, drain and spin each ask for something different. On the Delta 3 Max display I saw the load swing from the low end around 40W up toward about 290W at the busier moments. In the frame below, the AC output was reading in the high 200W range while the battery was still in the low 50s.

I also watched the EcoFlow app mid-cycle. At one point it showed about 146W of AC output with the pack around the high 40s to low 50s, which lines up with the gentler parts of a Normal cycle — rinsing or lower-agitation segments rather than a hard spin.

None of those peaks came close to the Delta 3 Max’s 2,400W continuous rating, and I did not need X-Boost. A standard 120V impeller top-loader is a comfortable load for this station.

Battery After a Full Load: 53% to 47%

From start to finish the wash, rinse and spin took about 1 hour and 8 minutes. When the cycle ended, the Delta 3 Max was at 47%. That is a 6% drop on a 2,048Wh pack, which works out to roughly 123 Wh of battery energy for the whole load.

A few notes on that 123 Wh figure:

• It is energy pulled from the battery, including inverter overhead, not a separate kill-a-watt reading at the washer cord.
• 6% of 2,048Wh is about 123Wh on paper, which matches the estimate I use in the video.
• Your washer, load size, water temperature and cycle length will shift the number. A heavier soil setting, hotter wash or longer spin can use more.

How Many Loads on a Full Charge?

If one full load took about 6% of the pack, a full charge could theoretically support around 16 similar washes. That is the fun headline number, and it is useful for outage planning, but real life is messier:

• Different washers draw differently. A compact 120V unit may use less; a heated or high-agitation cycle may use more.
• Cold-water Normal cycles are easier on the battery than hot washes that run an internal heater.
• You will usually want leftover capacity for lights, Wi-Fi, phone charging or a fridge — so planning on fewer than 16 laundry-only loads is the practical move.
• I moved the clothes to the dryer afterward on normal house power. A typical electric dryer is 240V and is not something the Delta 3 Max is meant to run.

For a home backup kit, laundry is one of the more satisfying loads this station can cover: it is short, the wattage stays modest and you still have most of the battery left when the buzzer goes off.

Saving Money vs Staying Powered

A portable power station does not create free electricity. If you charge the Delta 3 Max from the wall at the same rate your washer would have used from the wall, you are mostly shifting when the energy is drawn, not cutting the kWh.

Where it can help your bill is when you refill the station from solar or from the grid during cheaper off-peak hours, then run laundry from the battery later. Pairing the Delta 3 Max with solar input (up to 500W on this model) is the cleaner path if bill savings are the goal. For outage readiness, the value is simpler: you can still wash clothes when the grid is down.

If you want the recharge side of this station, I timed a wall charge from 29% to 100% in my Delta 3 Max AC charging test.

Why the Delta 3 Max Handles a Washer So Comfortably

A few specs explain why this pairing felt easy:

• 2,400W continuous AC — well above the ~40–290W I saw from the washer.
• 4,800W surge — covers motor start spikes that can briefly exceed the running watts.
• 2,048Wh LFP capacity — enough that a single load is a small slice of the pack.
• Pure sine wave outlets — a good match for appliance motors and electronics.

I have also written about other outage loads on this same station, including whether it can run a space heater and run an electric blanket. Laundry sits at the efficient end of that spectrum; space heaters burn through watt-hours much faster.

Practical Tips If You Try This at Home

Who This Setup Is For

This test is most useful if you already own or are considering the EcoFlow Delta 3 Max as home backup and you want to know whether laundry is realistic during a multi-hour or multi-day outage. Based on my numbers, it is. One full load was a small bite of the battery, the inverter never sounded strained and I still had roughly half the pack left for everything else.

It is a weaker fit if your main goal is shaving a few cents off every wash from wall power alone, or if your laundry pair is a 240V electric dryer you hoped to run from the same box. Use solar or off-peak charging when you care about cost, and treat the station as backup for the washer and the rest of the house’s 120V needs.

Final Take

Yes — the EcoFlow Delta 3 Max can run a full-size 120V washing machine. My Samsung 5.2 cu ft top-load used about 6% of the battery (≈123 Wh) for a complete 68-minute regular cycle, with draw swinging from roughly 40W to 290W. That leaves a lot of capacity for the rest of an outage day, and it makes laundry one of the more efficient big-appliance wins for this power station.
