Summary

Huge output, no stand, mixed warranty

What it is: a 600 W six-section folding panel with MC4 output, an XT60 lead and tie-down ropes in the box
The trade-off: typical folding-panel efficiency and a lot of watts per pound, but no stand and warranty terms that disagree
Not checked: the temperature coefficient and bypass diodes; ALLPOWERS publishes neither
Look elsewhere for: a built-in stand, an ETFE front or one clear warranty term

Strengths

Very high output from one panel
Light for its output
Folds to a compact case
Tie-down ropes and hooks in the box
Station lead in the box

Drawbacks

No stand or kickstands
Warranty terms conflict across documents
Weak output guarantee
Waterproof rating differs between manual and page
No temperature coefficient published

RedditBrand-level4 out of 10

r/SolarDIY: an owner of the 400 W folding panel read at best the mid-270s W at midday under a clear sky on a third-party station, about 68 percent of rated (June 2023)
Replies: commenters found its 37.4 V and 10.6 A within the station's input and asked whether shade or a battery above 75 percent was limiting it (June 2023)
r/GoRVing: an owner whom ALLPOWERS offered a station for review found its 100 W folding panel light, well made and quick to set up, but hard to open in wind (2024)

GoogleBrand-level5 out of 10

OutdoorGearLab: bought its own SP012 100 W folding panel and earns commission through links; it held 40.3 W in direct sun, near the top of the test, and put 56.8 Wh into a test battery (July 2024)
Shortfalls: OutdoorGearLab measured about 7 W in indirect light and noted the SP012 has no kickstand (July 2024)
The Gadgeteer: tested a 400 W SP037 that ALLPOWERS supplied, with an Amazon code; read 42 V open-circuit on an overcast 31 °F day and liked its kickstands and cable pocket, but measured no watts (January 2023)

Jasonoid: tested the SP039 and called it fairly light at 27 lb for the highest-rated portable panel he had tested (January 2024, about 36,000 views)
