How these alternatives compare
FlexSolar 100W Foldable Solar Panel
The FlexSolar LX-C100pro shares the 100W output and IP67 waterproof rating with the SOLUPUP panel. It differs by adding a built-in kickstand for easier angle adjustment and including USB-C and USB-A ports alongside the MC4 output. This model weighs 8.4 lbs, which is nearly double the SOLUPUP weight. You gain versatile connectivity for direct device charging but sacrifice the ultra-lightweight portability of the 4.2 lb SOLUPUP unit. Choose this if you need direct USB ports and stable positioning over minimal pack weight.
SOKIOVOLA 100W Foldable IP68 Solar Panel
The SOKIOVOLA SJSO100 offers IP68 waterproofing, which exceeds the SOLUPUP IP67 rating for better submersion resistance. It also weighs 4.6 lbs, slightly more than the SOLUPUP 4.2 lb panel. Both provide 100W power via MC4 connectors. The SOKIOVOLA is a foldable panel designed for rugged outdoor use. You get superior water protection and a similar form factor. Pick this alternative if maximum weather resistance is your priority and the small weight difference is acceptable for your gear setup.
FlexSolar 100W Foldable Solar Panel
The FlexSolar lx-S100 is a lighter 100W option at just 4.1 lbs, beating the SOLUPUP weight. It features USB-C and USB-A ports for direct charging, unlike the SOLUPUP MC4-only output. Both panels are waterproof with IP67 ratings. The FlexSolar model folds to a compact size suitable for backpacking. You gain direct device charging capability and slightly less weight. Choose this if you want to charge phones directly without a power station adapter and need the lightest possible 100W panel.
Holdwell S 300W Foldable Solar Panel

SinKeu 100W Foldable Solar Panel
The SinKeu S100 provides 100W power with a USB-C port for direct smartphone and tablet charging. It weighs 7.1 lbs, which is heavier than the SOLUPUP 4.2 lb panel. Both are foldable and waterproof, though the SinKeu lacks a specified IP rating in the data. The SinKeu focuses on direct device connectivity rather than MC4-only output. You gain convenient USB-C charging but accept more weight and potentially less detailed weather protection specs. Pick this if you frequently charge mobile devices directly.
VLAIAN 100W Foldable Solar Panel
The VLAIAN XY-100W delivers 100W power with MC4 and DC output ports. It weighs 4 lbs, making it slightly lighter than the SOLUPUP panel. Both are foldable and designed for camping and RV use.
