FlexSolar 100W Foldable Portable Solar Panel — IP67 Waterproof, ETFE Coating, 4-in-1 Adapter Kit

FlexSolar 100W Portable Solar Panel is a foldable, IP67-rated solar charger with multiple adapter outputs that delivers up to 100W of sunlight-to-power conversion for charging power stations, 12V batteries, and USB devices while off-grid.

This upgraded FlexSolar panel blends a high-efficiency monocrystalline array with a lightweight, folding design and included 4-in-1 M-C-4 connector set to give travelers, campers, and emergency preppers a reliable way to harvest sun power. Built with ETFE-coated cells and a slightly convex surface, it is designed to resist scratches, repel water and dust, and withstand outdoor use while folding down small enough for backpacks, RV storage bays, or car trunks.

How much power can I expect from this panel in real conditions?

Under ideal, direct sun the FlexSolar panel can deliver close to its 100W rated output; real-world yields will vary with sunlight intensity, angle, temperature, and shading. Morning/late-afternoon sun or cloudy conditions significantly reduce output, and the panel does not store energy—connect it to a compatible power station or charge controller to save electricity.

• Peak output: up to 100W in strong direct sunlight
• Conversion: high-efficiency monocrystalline cells with ETFE coating (up to ~24%)
• Performance factors: angle, time of day, cloud cover, and temperature
• Storage: requires an external battery, power station, or charge controller (sold separately)

Which portable power stations and devices will it connect to?

The included 4-in-1 M-C-4 connector set (XT60, Anderson, DC5521, DC7909) and the panel’s M-C-4 output make the FlexSolar broadly compatible with most consumer portable power stations and 12V battery systems. Popular brands such as EcoFlow, Jackery, BLUETTI, Anker, Goal Zero and many more are supported via the supplied adapters; double-check your device’s input jack and voltage requirements before connecting.

• Adapters included: XT60, Anderson, DC5521, DC7909 (4-in-1)
• Common compatibility: EcoFlow RIVER/DELTA series, Jackery Explorer models, BLUETTI EB series
• 12V battery charging: use the M-C-4 output plus a separate solar charge controller
• Note: always confirm adapter fit and polarity for your power station model

Is this panel durable and suitable for outdoor use?

The FlexSolar panel is built for outdoor conditions with an IP67 rating, ETFE top sheet and anti-scratch finish, making it resistant to rain, dust and light impacts. Its foldable fabric housing and built-in adjustable kickstands let you position the panels quickly on uneven ground, on RV roofs, or beside campsites.

• Weather rating: IP67 waterproof and dustproof
• Top layer: high-transmittance ETFE for durability and improved light capture
• Form factor: folds compactly from 47.1" x 22.8" down to 22.8" x 23.4"
• Weight & carry: approximately 8.4 pounds and easy to transport

How do I set it up for best charging and what accessories are needed?

Place the panel on flat ground or on an angled surface using the built-in kickstands, aiming it toward the sun with minimal shading. For energy storage connect to a compatible portable power station via the supplied adapter; to charge a vehicle or house 12V battery, pair the M-C-4 output with an appropriate solar charge controller (not included).

• Positioning: tilt toward the sun and avoid shade for optimal output
• To save energy: plug into a power station with matching adapter
• For 12V batteries: use a separate solar charge controller between panel and battery
• Care: wipe clean, fold dry, and store away from prolonged harsh conditions

Who this is for: the FlexSolar 100W panel suits weekend campers, RV owners, overlanders, and anyone needing a compact, durable solar charger to top up portable power stations or maintain 12V batteries while off-grid. It’s ideal for users who want broad connector compatibility out-of-the-box and a lightweight panel that packs down for travel, while technicians and homeowners may prefer adding a dedicated solar controller for tight battery charging control.
