Renogy 400W Portable Solar Panel 25% Efficient Foldable Blanket — Lightweight, Rugged ETFE with 10 ft Cable

The Renogy 400W Portable Solar Panel is a 25%-efficient, 16-fold solar blanket designed to deliver full 400W output in a lightweight, packable form for charging power stations and batteries off-grid.

Designed for campers, vanlifers, and emergency-ready households, this Renogy foldable solar panel balances high cell efficiency with rugged portability. It uses 16BB N-type cells to squeeze more energy from limited sunlight, folds to a backpack-friendly size, and includes a 10 ft cable so you can connect directly to portable power stations or 12V/24V battery systems. Built with ETFE lamination and reinforced stitching, the unit resists harsh conditions while remaining easy to move and set up.

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

Rated at a continuous 400W peak, the panel’s 25% efficiency improves energy harvest compared with many conventional 9BB modules. Output varies with sunlight, angle, and temperature, but the high-efficiency cells produce more usable watts per square foot—especially helpful in partial sun or tight installations.

• Maximum rated output: 400W under standard test conditions.
• 25% module efficiency using 16BB N-type cell architecture.
• Better performance in diffuse light and limited roof/ground area.
• Compatible with 12V/24V systems and portable power stations.

How easy is it to carry, store, and set up for camping?

The Renogy solar blanket folds into a compact 16.54 x 15.83 x 4.13 in package and weighs just 16.09 lbs, so it’s significantly lighter and smaller than many 400W rigid panels. Carrying is simple thanks to a padded handle and adjustable shoulder straps, and its multiple mounting options make deployment flexible at campsites.

• 16-fold design packs down to backpack-sized dimensions.
• Padded handle plus shoulder straps for comfortable transport.
• Lay flat, prop on the ground, hang between trees, or drape over a windshield.
• Stores neatly in tight RV compartments or vehicle trunks.

Will this panel survive outdoor use and varying weather?

Renogy built the 400W blanket for rugged conditions: ETFE lamination, reinforced stitching, and an IP65 rating protect against splashes and dirt. It’s rated to operate in a wide temperature range and carries multiple safety and quality certifications for dependable field use.

• IP65 ingress protection against water jets and dust exposure.
• Operational range from -10°C to 65°C for broad climate use.
• Military-grade ETFE lamination reduces micro-crack risks.
• UL 61730, CE, RoHS, FCC and ISO 9001 manufacturing standards.

How does the panel connect to my power equipment?

The 400W kit includes a 10 ft (3 m) cable so you can reach a power station or battery without awkward placement. It supports common battery chemistries and inverter systems when paired with the appropriate charge controller or power station input.

• Included 10 ft cable for direct connection to power stations.
• Works with AGM, LiFePO4 and deep-cycle batteries when used correctly.
• Use with MPPT charge controllers or compatible power station inputs.
• Delivers full panel output regardless of mounting orientation.

Who is this for? The Renogy 400W Portable Solar Panel suits campers, overlanders, vanlifers, and homeowners seeking compact emergency backup power. It’s ideal if you need a lightweight, high-efficiency solution that fits inside cramped vehicle storage, performs well in partial sun, and can be carried and deployed by one person. Choose this panel when portability, efficiency, and rugged field performance matter more than permanent rooftop installation.
