Solar charge controller with dual USB ports designed to optimize the charging of portable solar generators and USB devices while improving conversion efficiency between solar panels and battery storage. Key benefits Improves energy conversion: Helps convert solar panel output into usable power for your solar generator more efficiently, reducing energy loss during charging. Dual USB convenience: Two built in USB ports allow simultaneous charging of phones, tablets, power banks, and other USB devices without needing separate adapters. Simplified operation: Straightforward connections make it easy to integrate with portable solar panels and solar generators for everyday use. Space saving design: Compact and lightweight form factor fits into small kit bags, RV compartments, or toolboxes for on the go use. Durable build: Robust housing and reliable components provide consistent performance in regular outdoor and mobile applications. Functions and compatibility Regulates solar input and routes power to a connected solar generator or battery system while providing USB outputs for devices. Compatible with most portable solar panels and portable solar generators that accept an external charge controller connection. USB ports supply standard USB charging for small electronics while the controller manages conversion from solar input to storage. Performance and practical attributes Designed for stable USB output so devices can charge reliably while the solar generator receives power. Compact footprint and low weight make it suitable for portable and temporary installations. Simple connection layout reduces setup time and lowers the chance of wiring errors. Typical use scenarios Camping and outdoor trips: Keep phones, lights, and power banks charged from your solar panel while the solar generator stores energy for later use. Emergency and backup power: Maintain generator battery charge during a power outage and charge essential devices simultaneously via the USB ports. RV and van life: Integrate the controller into a portable solar setup to support small appliances and electronics while on the road. What to expect A practical accessory for anyone using portable solar panels and solar generators who needs reliable USB charging and improved conversion efficiency. A compact, easy to install controller that fits into mobile power setups without adding bulk or complexity. Note: Check compatibility with your specific solar panel and solar generator model before installation to ensure correct connections and performance.
