ECOGREAT PowerMax 1800SE, 1024 Wh, 1800 W review
A 1024 Wh LiFePO4 station rated 1800 W with eleven outputs, charged from 0 to 80 % in a stated hour at 800 W, and controllable from a phone application.
The bottom line The most generously connected station of the nine, with three mains sockets, an 800 W solar input and a seven-year warranty. It is also the one that sells itself on appliances while publishing no surge rating and no temperature range — the two figures those appliances actually turn on.
A 1 kWh class station sold on output count and on charging speed.
What it publishes
1024 Wh, 1800 W rated, and eleven outputs of which three are mains sockets. Charging is quoted from 0 to 80 % in an hour at 800 W from the mains, and a full solar charge in 1.5 hours at an 800 W input — a substantial solar ceiling.
What it sells and what it omits
The listing names heated blankets, hair dryers, kettles and microwaves. Every one of those is a motor or a heating element, and neither a surge rating nor its duration appears anywhere on the sheet. Nor does an operating temperature range.
The cycle figure
Over 3500 cycles, described as fifteen years, with no capacity percentage. That is the commonest form of this claim on the shelf and the least comparable.
What comes with it
An application for monitoring input, output and remaining charge, and a stated seven-year warranty. The package contents are listed bullet by bullet, which makes the second-purchase question — what else is needed before it works — easy to answer here.

Questions owners ask about this one
Can it really run a kettle and a microwave?
The second bullet names both among 1800 W appliances. Electrically that is a continuous-rating question and the answer is yes; in practice a heating appliance drawing near 1800 W empties 1024 Wh in well under an hour, which the listing does not mention.
Why does a missing surge rating matter here?
Because a microwave and a fridge both draw far more at the instant they start than while they run. Without a published peak and its duration, there is no way to tell from the sheet whether a given motor will start.
1024 Wh nominal · 2000 W continuous, 3000 W peak · 4000 cycles to 80 % · full in 49 min at 1600 W · 600 W solar at 60 V max · 10 ms UPS · 9 ports
A 1024 Wh station rated 2000 W continuous and 3000 W peak, charged in a stated 49 minutes at 1600 W, with a 600 W solar input capped at 60 V and a 10 ms switchover.
Best for: A household that will pair the station with panels and wants the input window published rather than guessed.
1024 Wh nominal LFP · 2600 W · 0–80 % in 37 min · 10 ms UPS switchover · 26 dB stated · 2× 140 W USB-C · 5-year warranty
A 1024 Wh LFP station rated 2600 W that reaches 80 % in a stated 37 minutes, switches to battery in 10 ms, and carries two 140 W USB-C ports and a five-year warranty.
Best for: Someone already inside the DJI ecosystem, or anyone who needs the shortest recharge and a documented switchover time.
288 Wh nominal · 300 W DC · LiFePO4, 4000 cycles · 80 % in about 70 min on USB-C plus solar · 5 outputs · about 2.5 kg
A 288 Wh LiFePO4 station rated 300 W, charged over USB-C, solar or a car socket, with three USB-C ports of which two are rated 140 W and an integrated cable that doubles as the handle.
Best for: Someone charging laptops and cameras rather than running mains appliances, who wants a published temperature range.
