15W*4 5V12V Solar Panel Car Battery Charger with USB DC Chain Output Ports Portable Waterproof 1 white

About this item

• Features: [Parallel connection]: This product can support high current fast charging, and can be used in parallel with up to 5 solar panels. Multiple solar panels are connected in parallel to DC5521 port to increase output power [Integrated intelligent charging chip]: Built in PWM circuit scheme, no need for controller to convert voltage, direct use [Intelligent Protection]: Built in charging microprocessor, improved charging algorithm, can provide overvoltage protection, overcharging protection, short circuit protection, etc. It can prevent reverse charging and can be safely used for charging and maintenance of 12V batteries. [Product Usage]: Charging devices such as mobile phones, mobile power supplies, and automotive batteries [Widely used]: The accompanying 3-piece SAE cable kit is plug and play and can be used in cars and 12V batteries. Equipped with hooks and suction cups, it can meet your different installation needs. Applicable to] Kind reminder: This product uses monocrystalline silicon material, which increases the photoelectric conversion efficiency by about 21.5percent compared to polycrystalline silicon. It has high conversion efficiency and generates more electricity in sunny environments than polycrystalline silicon; When multiple 2 or more solar panels are used in parallel, there may be a difference of approximately 5percent in power output, which is a normal phenomenon!
