EcoFlow DELTA 3 Plus vs Pecron E1000LFP
Two expandable 1,024 Wh LiFePO4 units with 1,800 W of output: EcoFlow's DELTA 3 Plus against Pecron's E1000LFP. The E1000LFP is the cheaper energy, 45% less per watt-hour at the makers' prices. The DELTA 3 Plus is 1.4 lb lighter, refills from the wall in 56 minutes against 1 hour 18 minutes and takes 1,000 W of solar against 600 W: buy it for that, and the E1000LFP for the money once Pecron has it in stock.

Cycle counts are highlighted only when both makers rate them to the same remaining capacity. A full recharge is not ranked against a charge to 80%. Missing figures never count as an advantage. These are manufacturer ratings; matching endpoints do not prove identical test conditions.
Rated cycles: DELTA 3 Plus, 4,000 to 80%; E1000LFP, 3,500 to 80%.

Estimated AC energy = rated Wh × 0.85. Runtime = estimated AC energy ÷ load W, with no reserve. Capacity and weight differences use the displayed figures; price per Wh uses each model's own price and the day it was checked. The device draws are in the watt-hour calculator.
- Capacity: E1000LFP minus DELTA 3 Plus = 0 Wh (0% of the DELTA 3 Plus figure).
- Carry weight: E1000LFP minus DELTA 3 Plus = 1.4 lb (5.1% of the DELTA 3 Plus figure).
- Price per Wh: E1000LFP minus DELTA 3 Plus = -0.31 USD/Wh (-44.5% of the DELTA 3 Plus figure).
Will it run your gear?
Check whether each unit has enough battery and output for the devices you want to run.
| Use | Needs | DELTA 3 Plus | E1000LFP |
|---|---|---|---|
| a day of home backup (a full-size refrigerator, a router, phones and lights for a day) | 2,323 Wh, 161 W running, 1,351 W startup | no: too little capacity | no: too little capacity |
| a night of CPAP (a CPAP with its humidifier for one 8-hour night) | 599 Wh, 53 W running, 104 W startup | yes | yes |
| two nights of camping (camp lights, phones, a laptop and a fan for two nights) | 2,066 Wh, 157 W running, 157 W startup | no: too little capacity | no: too little capacity |
| a day in an RV (a day of RV lights, TV, phones and a laptop) | 648 Wh, 156 W running, 156 W startup | yes | yes |
| a working day in a van (a working day of laptop, Starlink, lights and a fan) | 1,674 Wh, 189 W running, 189 W startup | no: too little capacity | no: too little capacity |
| a laptop and two phones (a laptop for six hours and two phone charges) | 396 Wh, 60 W running, 60 W startup | yes | yes |
Runtime by device
Hours = capacity × 0.85 ÷ device watts, with the draws from the device table; "Start" says whether the output and surge ratings cover the startup figure we use for each device (the refrigerator, 1,300 W startup allowance, from a larger 27 cu ft Whirlpool's tech sheet), so a "yes" there means likely, not certain, to start yours.
| Device | Draw W | DELTA 3 Plus h | Start | E1000LFP h | Start |
|---|---|---|---|---|---|
| CPAP machine (with heated humidifier) | 53 | 16.4 | yes | 16.4 | yes |
| Refrigerator (full-size, ENERGY STAR, ~18 cu ft top freezer) (average draw) | 41 | 21.1 | yes | 21.1 | yes |
| Laptop (MacBook Air, charging) | 40 | 21.8 | yes | 21.8 | yes |
| Wi-Fi router | 24 | 36.3 | yes | 36.3 | yes |
| Starlink Mini (router built in) | 33 | 26.8 | yes | 26.8 | yes |
| TV, 50-inch LED / Crystal UHD | 89 | 9.8 | yes | 9.8 | yes |
| Space heater, 1500 W | 1,500 | 0.6 | yes | 0.6 | yes |
Buy the DELTA 3 Plus if…
- you carry it more than you run it (27.6 lb against 29 lb)
- you need a higher solar input ceiling (1,000 W against 600 W); actual recharge depends on the panels
- it will sit between the wall and a refrigerator or router (maker-stated 10 ms switchover; 20 ms for the other)
- you want the higher stated cycle count at the same 80% remaining capacity (4,000 against 3,500); test conditions can still differ
- the longer warranty matters to you (5 years against 3 years)
Buy the E1000LFP if…
- you want the most stored energy per dollar ($0.39 against $0.70 per Wh)
- the $320 difference matters more than the specs

Questions buyers ask
Which is better for power outages, the DELTA 3 Plus or the E1000LFP?
EcoFlow DELTA 3 Plus states a 10 ms switchover, so it can sit between the wall and a fridge or router and take over when the power cuts, once the device is in an outlet the manual gives the backup to and any AC timeout is off (for a CPAP or a computer, check that device rides through the switch); Pecron E1000LFP states 20 ms. Capacity: 1,024 Wh each. Check your appliance's startup watts against the surge figures in the table.
Which is cheaper per watt-hour?
E1000LFP at $0.39 per Wh against $0.70. This compares purchase price with rated capacity, not lifetime delivered energy.
Can either run a window air conditioner?
Only if the air conditioner's running watts stay under the AC output (1,800 W on the DELTA 3 Plus, 1,800 W on the E1000LFP) and its start fits the surge figures in the table: read both on the air conditioner's label or in its manual, and test it before you rely on it. For the hours, multiply the rated Wh by 0.85 for inverter losses and divide by the running watts. A unit whose label says 500 W, for example, would run about 1.7 hours on the DELTA 3 Plus and about 1.7 hours on the E1000LFP on a full charge, if its compressor ran without a break.
