efficiency portable solar panel designed for reliable offgrid charging and lightweight installation. Key benefits Higher power output: Monocrystalline solar cells with back contact technology reduce frontside electrode shading, increasing conversion efficiency by about 50 percent compared to ordinary solar cells. This delivers more usable power in the same footprint. Weather resistant for outdoor use: IP65rated protection against dust and lowpressure water jets helps keep the panel operational in common outdoor conditions. Easy to carry and mount: Compact, lightweight design with a predrilled hole on the back for quick installation and secure fixing. Integrated charge management and charging convenience: Builtin solar charge controller compatible with 12 volt and 24 volt systems plus a USB output at 5V 2.5A for direct mobile phone charging. Features and specifications Solar cells: efficiency monocrystalline with back contact technology. Weather protection: IP65 waterproof and dustproof construction. Compatibility: Works with 12V and 24V charging systems. USB output: 5V 2.5A for charging phones and USBpowered devices. Mounting: Predrilled hole on the back for fast installation. How this solves common problems More usable energy in limited space: Higher conversion efficiency means you get more charge for batteries and devices without needing a larger panel. Reduced installation hassle: Lightweight size and a predrilled mounting hole make setup quicker and simpler for temporary or semipermanent installs. Onthego charging: Builtin controller and USB output let you charge a phone directly or keep a 12V battery topped up while away from mains power. Suggested use scenarios Camping and hiking basecamps: Mount on a tent frame, campsite table, or pack it for daytime charging of phones and small devices. Recreational vehicles and boats: Supplement onboard power with solar charging for 12V systems and use the USB port for onboard device charging. Emergency and backup power: Keep a 12V battery charged during outages or use the USB output to maintain essential communication devices. Materials, performance, and handling Durable construction for outdoor exposure with IP65level protection. Compact form factor and low weight for easy transport and mounting. Compatible with common 12V and 24V systems; USB output supports standard mobile device charging. What to expect Efficient, portable solar charging suitable for outdoor activities, small offgrid systems, and emergency backup. Simple mounting and integrated charge control reduce setup complexity while the USB output provides convenient device charging.
