The ALLPOWERS P1800 reading covers its product line.
What they say
FOSSiBOTF1800
In r/SolarDIY an owner said his F1800 rarely passed 85 to 90 percent on solar alone, its input stalling at 320 to 350 W from two 200 W panels in series at about 48 V (June 2026).
ALLPOWERSP1800
No owner thread names the P1800, so this reads its closest sibling, the 1,152 Wh R1500.
In r/GoRVing a UK owner's R1500 made a static or clicking noise above 30 W of AC load and would not connect by Bluetooth or Wi-Fi (2024), and in r/SolarDIY an R1500 owner could find no expansion battery for sale (March 2024).

What they say
FOSSiBOTF1800
No credible written test of the F1800 was found, so this reads the F2400 sold beside it. best-batteries.com, which links to retailers' prices, measured 1,512 to 1,807 Wh delivered from the F2400's 2,048 Wh, 78 percent round-trip efficiency and a full wall charge of 2 hours 30 to 2 hours 45 minutes at 1,100 W on a 230 V unit (August 2026).
The Van Conversion, which passes on FOSSiBOT discount codes, put a full wall charge of a UK unit at about 2 hours 40 minutes from its measured rate (August 2026).
ALLPOWERSP1800
Vantour, a French camper-van site that received the unit ahead of its review and sells it through its own price links, tested the 230 V European model: the station kept a workstation's external monitor running through a power cut, carried a hair dryer and the workstation at just over 1,000 W for about a minute, and was not loud at 50 cm while charging at about 550 W; it confirmed no expansion battery can be connected and found the screen labels the USB-C ports 100 W against ALLPOWERS' 140 W (August and September 2026).
