A long print fails when the power blips, so the station behind a 3D printer needs fast UPS switchover and enough capacity to finish the job, and the Anker SOLIX S2000 switches in 10 ms with 2,010 Wh behind it. The other two picks below hold a little more energy and put out more power, so the right one depends on the printer and the length of the print.
The makers’ published spec sheets for November 2026 form the basis for this guide. PowerPicked Editorial did not test any station in it, so every claim below comes from those sheets.
Anker SOLIX S2000
- Capacity
- 2,010 Wh
- AC output
- 1,500 W
- Weight
- 35.7 lb
Who it's for: Home backup buyers who want 2 kWh for a fridge and essentials in a box one person can carry.
Strengths
- Rated 6,000 cycles to 80% and 10,000 to 60%
- 10 ms UPS switchover
- Listed at 30 dB
Weaknesses
- Not expandable
- No 12V car port
What does a 3D printer need?
A 3D printer draws steady power for hours, and a brief outage can ruin a print that took all day. A station with UPS mode switches to battery in milliseconds, so the print keeps going through a short cut. Capacity decides how much of a long print the battery can cover, and rated output must cover the printer at every point.
Check the nameplate on your printer first, then match its rated and surge draw against each station’s output before you buy.
Anker SOLIX S2000
The S2000 is the main pick for a long print. It holds 2,010 Wh and puts out 1,500 W, with a 3,000 W peak. Its UPS switchover runs at 10 ms, and it lists 30 dB of noise. At 35.7 lb, it is the lightest pick here and fits on a bench beside the printer.
Six thousand cycles keep 80% of its capacity, and ten thousand keep 60%, so the battery lasts through years of prints. Its warranty runs five years, and a full AC charge takes about 2.3 hours with UltraFast mode in the Anker app.
Its weak points are output, expansion, and ports. At 1,500 W, it puts out less than the other two picks. No expansion battery is supported for it, and it has no 12V car port.
Anker SOLIX C2000 Gen 2
- Capacity
- 2,048 Wh
- AC output
- 2,400 W
- Solar input
- 800 W
- Weight
- 41.7 lb
Who it's for: Home backup and RV buyers who want 2 kWh and a TT-30 outlet in a box lighter than most 2 kWh stations.
Strengths
- 2,400 W rated, 4,000 W peak
- TT-30 RV outlet
- 10 ms UPS switchover
Weaknesses
- Solar input tops out at 800 W
- Expands to only 4,096 Wh with one battery
Anker SOLIX C2000 Gen 2
For a fast refill, the C2000 Gen 2 is the pick. With 2,048 Wh inside and 2,400 W of output, it peaks at 4,000 W. Switchover runs at 10 ms, and the maker’s comparison table lists 30 dB. From a wall outlet it fills in 88 minutes. Pair wall and solar power at 2,600 W and the fill drops to 58 minutes.
A TT-30 RV outlet fits a workshop hookup. Two USB-C ports at 140 W each charge a laptop at full speed. One extra battery lifts it to 4,096 Wh in total. Anker lists a five-year warranty for it. At 41.7 lb, its weight falls between the other two.
Its limits are solar input and expansion. Panels feed it at most 800 W, and it accepts just one extra battery. It measures 18.1 by 9.8 by 10.1 in, so leave a clear spot on the bench.
EcoFlow DELTA 3 Max
- Capacity
- 2,048 Wh
- AC output
- 2,400 W
- Solar input
- 500 W
- Weight
- 44.7 lb
Who it's for: Home backup buyers who want 2 kWh with 20 A outlets in a quiet box.
Strengths
- 2,048 Wh with 2,400 W output
- 25 dB at 600 W (maker's test)
- Under 10 ms UPS switchover
Weaknesses
- Solar input only 500 W for a 2 kWh battery
- 0-80% takes 68 minutes on AC
- Heavy at 44.7 lb
EcoFlow DELTA 3 Max
For a quiet print room, the DELTA 3 Max is the pick. Inside it are 2,048 Wh, and output runs at 2,400 W, with X-Boost reaching 3,400 W. Switchover runs in under 10 ms, the fastest of the three picks. The maker’s test lists 25 dB or less at 600 W.
Each of its four 120V outlets runs at 20 A at most. USB-C ports run at 100 W and 30 W, with one 18 W USB-A port beside them. The warranty spans five years: three standard, plus two more once you register in the app.
Its limits are solar input, charging time, and expansion. Panels feed it at most 500 W despite the 2 kWh battery. AC power needs 68 minutes to reach 80%, and no expansion battery is listed for it.
How long will they run?
For the runtime math in this section, assume 85% of the listed capacity is what your devices can use. That gives 1,708.5 Wh of usable energy from the listed 2,010 Wh of the S2000. A 50 W load runs for about 34.2 hours on that energy.
| S2000 | C2000 Gen 2 | DELTA 3 Max | |
|---|---|---|---|
| Capacity | 2,010 Wh | 2,048 Wh | 2,048 Wh |
| Usable energy at 85% | 1,708.5 Wh | 1,740.8 Wh | 1,740.8 Wh |
| Runtime at 100 W | about 17.1 hours | about 17.4 hours | about 17.4 hours |
| Wh per pound | about 56.3 | about 49.1 | about 45.8 |
| UPS switchover | 10 ms | 10 ms | under 10 ms |
All three run a 100 W load for nearly the same time: about 17.1 to about 17.4 hours. A printer draws more while it heats, so the hours above overstate how long a print lasts on battery alone.
How to choose
Pick the S2000 when you want the lightest box with the longest battery life and a 10 ms switchover. Go with the C2000 Gen 2 for more output, a faster refill, and a TT-30 outlet.
Go with the DELTA 3 Max for the fastest switchover and the lowest listed noise in a print room. Check the nameplate on your printer first, then match its rated and surge draw against each station’s output.
FAQ
Will a power station keep a print going through an outage?
Yes, when it has UPS mode and enough capacity. Each pick here switches in 10 ms or less, so a brief cut does not stop the print. Capacity decides how much of a long print the battery can cover.
How much capacity does a long print need?
That depends on the printer’s draw and the length of the print. The S2000 holds 2,010 Wh, and the C2000 Gen 2 and the DELTA 3 Max hold 2,048 Wh each. Read the nameplate on your printer and work out the hours from its rated draw.
Can I charge these stations from solar while printing?
The C2000 Gen 2 takes up to 800 W of solar, and the DELTA 3 Max takes up to 500 W. The S2000 charges from a wall outlet.
Which station here takes an extra battery?
The C2000 Gen 2 grows to 4,096 Wh with one extra battery. No expansion battery is supported for the S2000, and no expansion battery is listed for the DELTA 3 Max.
