Engineered with high-efficiency N-type monocrystalline solar cells, this 40W foldable charger is built for rugged portability. As an experienced camping gear manufacturer supplying USA and European B2B channels, we integrate IP67 waterproof textiles and smart IC power management to provide global distributors with a high-margin off-grid power solution.
This 40W foldable solar charger is engineered for outdoor retail, emergency-prep channels, and distributor programs that need MPPT efficiency, multi-port charging, and a compact folded cube. Factory-direct paths support repeat MOQs, neutral master cartons, and OEM labeling.
Outdoor power anxiety versus sun-powered peace of mind — one panel for phones, cameras, power banks, and portable power stations.
Never Run Out of Power · Stay Connected Outdoors
40W · MPPT · 12V DC + QC 27W + PD 18W · IP67 · 750g portable
A foldable solar panel charger converts sunlight directly into electricity for connected devices. Unlike power banks, it has no internal storage — output is instantaneous and depends on sun angle, shade, and weather.
This SKU pairs Maximum Power Point Tracking (MPPT) with QC3.0 USB-A, PD2.0 USB-C, and 12V DC outputs so channel partners can position it in outdoor retail, emergency prep, and portable power assortments alongside power stations and cables.
The MPPT controller continuously adjusts voltage for optimal charging efficiency — marketed at up to 23% higher harvest versus standard charging in comparison graphics, with multi-layer overcurrent, overvoltage, overheating, and short-circuit protection.
Compact & Expandable · pocket-sized folded / wide-area deployed
Roughly tablet-sized when folded — fits backpack side pockets
12V DC max 40W · PD2.0 USB-C max 18W · QC3.0 USB-A max 27W (confirm port layout on production sample)
Reference charging speeds and output split under ideal direct sun — actual results vary with weather, angle, and device protocols.
