1A MPPT Solar Charge Controller, 3.314V Adjustable Output, Emergency Light for Camping Lanterns

**Product Overview** A compact 1 amp maximum power point tracking (MPPT) solar panel controller module designed for portable power applications. The unit provides an adjustable voltage output, integrated emergency lighting, and a dedicated charging port for camping lamps. Its robust housing and efficient conversion make it suitable for off‑grid use, emergency preparedness, and recreational activities. **Key Benefits** ** conversion efficiency** – MPPT technology extracts maximum power from low‑output solar panels, ensuring more usable energy from limited sunlight. **Adjustable output voltage** – A built‑in potentiometer lets the user set the output to match the voltage requirements of various small devices, from 5 V USB gadgets to 12 V lighting circuits. **Built‑in emergency lamp** – A bright, low‑power LED is always ready, providing reliable illumination when solar input is unavailable. **Dedicated camping‑lamp charging port** – Allows direct charging of standard camping lanterns without additional adapters. **Compact and lightweight** – Dimensions roughly 90 mm × 55 mm × 30 mm and a weight under 150 g, making it easy to carry in a backpack or store in a vehicle. **Durable enclosure** – Constructed from impact‑resistant ABS plastic with an IP54 rating for protection against dust and splashing water. **Specifications** Input voltage range: 6 V to 18 V (compatible with 5 W – 20 W solar panels) Maximum output current: 1 A continuous Output voltage: Adjustable 3.3 V to 14 V Emergency lamp: 0.5 W LED, runtime up to 10 hours on internal reserve battery Charging port: 5 V DC, up to 500 mA for camping lamps Operating temperature: –10 °C to 50 °C Protection features: Over‑charge, over‑discharge, short‑circuit, and reverse‑polarity protection **Typical Applications** 1. **Backpacking and camping** – Connect a small fold‑out solar panel to keep a headlamp or portable lantern charged throughout the night. The adjustable output can also power a USB phone charger. 2. **Emergency preparedness kits** – Store the controller with its internal reserve battery. In a power outage, the emergency LED provides immediate illumination, and the adjustable output can revive essential low‑power devices. 3. **Off‑grid maintenance tools** – Use the module to power handheld diagnostic equipment or battery‑operated radios on remote job sites where only a small solar panel is available. **Why Choose This Controller** Simple, tool‑ adjustment of output voltage eliminates the need for multiple regulators. Integrated lighting and charging functions reduce the number of separate accessories required for outdoor or emergency use. MPPT algorithm ensures the possible energy harvest from low‑power panels, extending the operating time of connected devices. Robust, weather‑resistant housing protects the electronics in harsh outdoor conditions. **Installation & Use** Connect the solar panel leads to the input terminals, observing polarity. Set the desired output voltage using the adjustment knob before connecting the load. Attach a camping lantern to the dedicated charging port or plug in other devices to the adjustable output. In the absence of sunlight, the emergency LED automatically activates from the internal reserve battery. This MPPT solar panel controller module offers reliable, adjustable power in a compact package, making it an effective solution for portable energy needs in outdoor, emergency, and remote scenarios.
