E-POWO 400W Portable Solar Panel - Foldable 23.5% Efficiency, Carry Case & 7-in-1 Cables

The E-POWO 400W Portable Solar Panel is a foldable, high-efficiency solar charger built to power portable power stations and outdoor electronics with up to 23.5% conversion efficiency.

This lightweight, suitcase-style panel packs monocrystalline cells with ETFE lamination into a weather-resistant, easy-to-transport design. It unfolds to deliver 400 watts of peak power, includes a 7-in-1 cable set for broad power station compatibility, and offers adjustable kickstands and reinforced mounting points so you can position it for maximum sun exposure while camping, traveling, or during power interruptions.

How much power can I realistically expect from this panel in outdoor use?

Rated at 400W peak output, actual energy production varies with sunlight intensity, angle, and weather. In clear, direct sun the panel approaches its rated output; on cloudy days or with shading the yield will drop.

• Peak rated output: 400 watts under optimal sunlight.
• Conversion efficiency up to 23.5% thanks to monocrystalline cells and ETFE coating.
• Performance affected by cloud cover, time of day, and panel tilt.
• Three adjustable angles (40°/50°/60°) help optimize daily energy capture.

What devices and power stations will it connect to?

The kit includes a 7-in-1 cable set and a solar connector compatible with many common inputs, so it works with most mainstream portable power stations and DC devices. This flexibility makes the panel useful for charging multiple types of gear at once.

• Includes Anderson, XT60, DC7909, DC5521, DC8020, DC5525, and DC35135 connectors.
• Can charge portable power stations, battery packs, inverters, and DC appliances.
• Simultaneous charging of multiple devices possible depending on station input limits.
• Always verify your power station’s maximum solar input to avoid overcurrent.

Is the E-POWO panel durable enough for camping and harsh weather?

Yes — the panel is designed for outdoors use with ETFE lamination, IP67-rated waterproof protection for the module, and a robust Oxford fabric casing. Reinforced grommets and a fiberglass structure improve stability and longevity under rough conditions.

• ETFE coating enhances dust resistance and weatherability for longer life.
• IP67-rated waterproof module protects against water intrusion during wet conditions.
• Fiberglass-reinforced structure and corrosion-resistant materials for rugged use.
• Reinforced grommets allow secure mounting to RVs, tents, or trailers.

How portable and easy-to-use is it for quick setup?

The panel folds into a compact briefcase-style package with a carryable form factor and an integrated accessory pouch. Built-in adjustable kickstands and three preset tilt positions make it straightforward to deploy on any flat surface without extra hardware.

• Folded dimensions: 37.76 x 24.96 x 1.3 inches; weight: 15.57 kg for manageable transport.
• Three-angle kickstands (40°/50°/60°) for rapid positioning and improved sun tracking.
• Accessory pouch stores the included 7-in-1 cable set and user manual.
• Reinforced handle and briefcase layout simplify carrying and storage.
