Multiple output ports: Dual USB+DC+Typc output ports, suitable for different devices. 4. Fast charging: High-rate battery, high conversion rate; high output power, fast charging. 5. Waterproof: IP67 protection, waterproof, moisture-proof and durable. Specifications: Product name: Solar Panel Regulator Color: Black Material: Plastic Input voltage: 5-30V Output voltage: 5V USB DC output: 18V Type-c output current: 5V 3000 mA (max) USB2.0 output: 5V 3000mA (max) Size: About 66*45*15mm/2.60*1.77*0.59inch(L*W*H) Package Includes: 1Pc * Solar Panel Regulator 1Pc * PCBA 1Pc * Bonding wire Instructions: 1. First use wires to weld the positive and negative poles of the product to the positive and negative poles of the solar panel; 2. When there is voltage input, USB will have voltage output. Note: Do not solder the positive and negative poles reversely during use, as this will burn out the circuit. 3. The output will have a red indicator light; 4. This product is a wide voltage step-down and regulated voltage controller with DC-DC multi-function series-parallel multi-purpose. It is suitable for series and parallel integration of solar energy products. Note: 1. Before use, please ensure that the positive and negative poles of this product are connected to the corresponding ones of the load. 2. If there is no professional technical personnel, please do not try to change the circuit or use method of the product. Our company is not responsible for disassembling the product or changing the circuit without authorization. 3. Please don't put the charger in outdoor solar energy for emergency charging in rainy days, so as not to cause circuit short circuit. (The front of the solar panel is not afraid of rain (note that no water enters the USB and DC ports.) _x000D_
