ETFE Foldable Solar Charger, 8W to 36W Options
Key Features
- Six real power choices: 8W, 12W, 15W, 21W, 30W and 36W
- ETFE lamination covers each folding cell assembly
- 8W uses polycrystalline cells; the other five ratings use monocrystalline cells
- USB-only and USB/DC configurations have different port layouts
- Folded and unfolded dimensions are specified separately for each rating
- Interface current limits are distinct from available panel output
Product Overview
The ETFE foldable solar charger range offers six power configurations with different footprints and output connections. The 8W, 12W and 15W versions provide 5V USB output; the 21W, 30W and 36W versions add DC connections. Compare the selected rating below before purchase. The stated 2A, 2.4A and 3A figures are interface current limits, not guaranteed solar generation.

Compatibility & Notes
Select the power configuration by its electrical output, connector layout and unfolded size. Interface limits of 2A, 2.4A and 3A are upper limits for the relevant connections; actual output depends on available sunlight and connected loads, and simultaneous outputs share the available generation. Unfold all sections toward direct sunlight. No battery storage is built in. Battery charging requires a compatible charge-control circuit.
