FlexSolar 30W vs 36W Specs

Rated Power Output

Edge: FlexSolar 36W Ultra-Portable Solar Panel

The FlexSolar 36W Ultra-Portable Solar Panel delivers a rated power of 36 watts. This is 6 watts higher than the FlexSolar 30W Foldable USB Solar Charger, which outputs 30 watts. Both units use monocrystalline cells to convert sunlight into electricity. The higher wattage on the 36W model suggests it can charge devices faster or power slightly larger loads under ideal sunlight conditions. You get more raw power with the larger model, making it the better choice if you need to charge multiple devices or larger batteries quickly.

Weight and Portability

Edge: FlexSolar 30W Foldable USB Solar Charger

Weight is a critical factor for hiking and backpacking. The FlexSolar 30W Foldable USB Solar Charger weighs 1.4 pounds according to its key specs, though its general specs list 1.1 pounds. The FlexSolar 36W Ultra-Portable Solar Panel weighs 1.7 pounds. The 30W model is lighter, which matters when every ounce counts in your pack. The 36W model is heavier but still described as ultra-portable. If minimizing weight is your priority, the 30W charger is the superior option for long-distance treks where light gear is essential.

Folded Dimensions

Edge: FlexSolar 36W Ultra-Portable Solar Panel

When folded, the FlexSolar 30W measures 8.0 x 12.4 x 1.6 inches. The FlexSolar 36W folds to a compact 7.7 x 5.1 inches. The 36W model is significantly narrower and shorter when closed, making it easier to slip into smaller pockets or side compartments. The 30W model is longer, resembling the size of a MacBook Air. If you want a panel that takes up less space in your backpack when not in use, the 36W model offers a more compact footprint.

Output Ports

Edge: FlexSolar 36W Ultra-Portable Solar Panel

Both chargers include USB-A and USB-C ports for charging phones and small electronics. The FlexSolar 36W adds a DC output port (5.5mm*2.1mm), allowing you to connect other small DC devices. The FlexSolar 30W lists only USB-C and USB-A outputs. The extra DC port on the 36W model provides more versatility if you use devices that require barrel jack connections. For users who only use USB devices, both are sufficient, but the 36W offers broader connectivity options.

Conversion Efficiency

Edge: Tie

Both solar panels boast a conversion efficiency of up to 24%. The FlexSolar 30W uses ETFE film to achieve this rate, while the 36W model uses military-grade solar arrays. Since both achieve the same percentage, neither has a technical advantage in energy conversion per unit of sunlight. You will get similar performance per watt of input in direct sun. The efficiency is identical, so this spec does not help you choose between the two models based on energy harvesting capability alone.

Which flexsolar solar charger suits you

You need extra power for longer trips

Our pick: FlexSolar 36W Ultra-Portable Solar Panel

The 36W model provides 6 watts more output than the 30W version. This higher rated power helps charge devices faster or run multiple gadgets simultaneously. Both units share the same 24% conversion efficiency, but the extra wattage gives you more total energy harvest from sunlight.

You want the lightest packable option

Our pick: FlexSolar 30W Foldable USB Solar Charger

The 30W charger weighs just 1.1 pounds, making it lighter than the 36W unit at 1.7 pounds. Its folded dimensions are 8.0 x 12.4 x 1.6 inches. This compact size allows you to easily stuff it into a backpack or hold it in your hand during hiking.

You need DC output for accessories

Our pick: FlexSolar 36W Ultra-Portable Solar Panel

The 36W panel includes a DC port alongside USB-A and USB-C outputs. This allows you to power small DC devices directly. The 30W model only lists USB-A and USB-C ports. If you use gear requiring a 5.5mm*2.1mm connector, this 36W panel is the better choice.
