Features: brand new and high quality Adopt imported high frequency low conduction internal resistance double MOS tube, 10A high current double diode, high efficiency flat high power inductor, constant copper current detecting resistor, perfect anti-reverse for protection of ultra low dropout, no work, no anti-reverse Connect the damaged charging board. Both the input and output terminals use high-end switching power supply and special high-frequency low-resistance electrolytic capacitor (LOW ESR) to ensure the output ripple. Can adjust the output voltage arbitrarily, CC-CW automatic control (can support single or multi-cell lithium battery or lithium iron phosphate or lead acid battery, high power LED, etc.). Battery for complete charge management. The maximum power point tracking of solar cells, the output current is greater than the solar panel current, the real ultra-high efficiency MPPT, support 8-28V, 100W solar high current charging. This product is suitable for 9V 12V 18V 24V solar panel, wind turbines, solar street lights, etc. It can also charge batteries, nickel-cadmium, nickel-metal hydride, lithium batteries (battery packs). Specifications: Material: PCB Input voltage: for DC 8-28V input for DC voltage (no input AC) Output voltage: for DC 5-26V stepless adjustable transmission Output current: 2A/5A Charging indicator: Yes.
