OPTISOLEX 440W Foldable Solar Panel Bag — 2×220W Split Solar Blanket, 25% N‑type Efficiency, Lightweight 17.2 lb Charger

The OPTISOLEX 440W Portable Solar Panel is a foldable, two-piece solarbag that delivers high-efficiency N-type cell power in a lightweight, travel-ready design for camping, RVs, boats, and off-grid use.

Designed to balance output, portability and durability, this solarbag splits into two 220W blankets that can be used separately or zipped together for higher production. At roughly 17.2 lbs and ETFE-laminated construction, it reduces carry burden while resisting weather and abrasion. Whether you need to top up a power station, maintain an RV battery, or charge phones and small appliances on the go, the OPTISOLEX 440W provides multi-port outputs and broad compatibility for field use.

How much energy can I realistically expect from this 440W solarbag?

Rated at 440 watts under ideal conditions, the panel uses N-type solar cells with up to about 25% conversion efficiency. Actual generation depends on sun angle, temperature, shading and system losses; in bright, direct sun you can typically expect higher output than comparable 400W kits.

• Rated 440W combined (two 220W blankets) using N-type cells
• Up to ~25% cell efficiency under optimal conditions
• Performance varies by sunlight intensity, orientation and temperature
• Each 220W section can operate independently for flexible placement

Can I run multiple devices or charge a battery and devices at once?

Yes — the OPTISOLEX solarbag includes six output ports for parallel charging and device support. It can feed a portable power station while simultaneously powering phones, tablets or small appliances, and each blanket can support multiple devices when split.

• Six fast-output ports: USB-C 45W, USB-A 18W, USB-A 15W, plus power delivery for stations
• Each 220W section supports up to three electronic devices concurrently
• Use split panels to charge two separate battery systems at once (e.g., RV plus power station)
• Works with most portable power stations; pairs with OPTISOLEX SolexBrick S1 for LiFePO4 charging

How portable and durable is the solarbag for outdoor travel?

The solarbag was engineered to be compact and lightweight without sacrificing ruggedness. Weighing 17.2 lbs, it’s substantially smaller and lighter than many fixed 400W systems and includes travel-friendly features like a handle and shoulder straps for easy transport.

• 17.2 lbs total weight — meets lightweight gear needs for camping and overland trips
• ETFE lamination and IP65 rating for weather resistance and outdoor durability
• Zippered split design for flexible placement and easier packing
• Carry handle and adjustable shoulder straps for convenient carrying

How compatible is the panel with different battery systems and set-ups?

This panel is built to integrate with a wide range of portable power solutions and vehicle batteries. It connects to most power stations, supports multi-voltage LiFePO4 charging when paired with the OPTISOLEX SolexBrick S1, and can be configured for 12V, 24V or 48V battery systems depending on the connected controller.

• Broad compatibility with popular portable power stations and inverters
• Supports 12V/24V/48V LiFePO4 charging when used with the SolexBrick S1 (sold separately)
• Can charge two independent systems simultaneously by splitting the blankets
• Includes standard connector options for field wiring and controllers

Who is this for: Outdoor enthusiasts, overlanders, RV and boat owners, and anyone who needs a high-output yet portable solar charging solution. If you prioritize light weight, split-panel flexibility and multiple fast-charge ports for phones, power stations or vehicle batteries, the OPTISOLEX 440W Solarbag offers a practical balance of power and portability for weekend trips, extended off-grid stays, and emergency backup power.
