EcoFlow DELTA Pro Ultra vs Pecron F5000LFP
Two whole-home systems with 7,200 W of output: EcoFlow's DELTA Pro Ultra (6,144 Wh) against Pecron's F5000LFP (5,120 Wh), both expandable to 30 kWh or more. The F5000LFP is the cheaper energy, 37% less per watt-hour at the makers' prices, is 57.9 lb lighter and is rated for 4,000 cycles against 3,500. The DELTA Pro Ultra holds 1,024 Wh more: buy it for that, and the F5000LFP 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 Pro Ultra, 3,500 to 80%; F5000LFP, 4,000 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: F5000LFP minus DELTA Pro Ultra = -1,024 Wh (-16.7% of the DELTA Pro Ultra figure).
- Carry weight: F5000LFP minus DELTA Pro Ultra = -57.9 lb (-31.8% of the DELTA Pro Ultra figure).
- Price per Wh: F5000LFP minus DELTA Pro Ultra = -0.25 USD/Wh (-37.2% of the DELTA Pro Ultra 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 Pro Ultra | F5000LFP |

| 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 | yes | yes |
| 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 |

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 Pro Ultra h | Start | F5000LFP h | Start |
|---|---|---|---|---|---|
| CPAP machine (with heated humidifier) | 53 | 98.5 | yes | 82.1 | yes |
| Refrigerator (full-size, ENERGY STAR, ~18 cu ft top freezer) (average draw) | 41 | 126.5 | yes | 105.4 | yes |
| Laptop (MacBook Air, charging) | 40 | 130.6 | yes | 108.8 | yes |
| Wi-Fi router | 24 | 217.6 | yes | 181.3 | yes |
| Starlink Mini (router built in) | 33 | 160.7 | yes | 133.9 | yes |
| TV, 50-inch LED / Crystal UHD | 89 | 58.7 | yes | 48.9 | yes |
| Space heater, 1500 W | 1,500 | 3.5 | yes | 2.9 | yes |
Buy the DELTA Pro Ultra if…
- you want the extra capacity (6,144 Wh against 5,120 Wh)
Buy the F5000LFP if…
- you want the most stored energy per dollar ($0.43 against $0.68 per Wh)
- the $2,000 difference matters more than the specs
- you carry it more than you run it (123.9 lb against 181.8 lb)
- you need a higher solar input ceiling (5,800 W against 5,600 W); actual recharge depends on the panels
- you want the higher stated cycle count at the same 80% remaining capacity (4,000 against 3,500); test conditions can still differ

Questions buyers ask
Which is better for power outages, the DELTA Pro Ultra or the F5000LFP?
EcoFlow DELTA Pro Ultra states a 20 ms switchover (0 ms as an online UPS), 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 F5000LFP states 20 ms (0 ms as an online UPS). EcoFlow DELTA Pro Ultra holds more (6,144 against 5,120). Check your appliance's startup watts against the surge figures in the table.
Which is cheaper per watt-hour?
F5000LFP at $0.43 per Wh against $0.68. 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 (7,200 W on the DELTA Pro Ultra, 7,200 W on the F5000LFP) 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 10.4 hours on the DELTA Pro Ultra and about 8.7 hours on the F5000LFP on a full charge, if its compressor ran without a break.
