USB output with 2.5 A maximum current and resistanceaware charging. It can identify resistance and charge multiple phones simultaneously via USB. Input and output use screw terminals for convenient, secure cable connections and easy disconnection when reconfiguring. DCDC stepup power module designed to power electrical equipment and digital devices with a reliable voltage boost. Also suitable as a laptop power supply or as a voltage regulator for solar panels, enabling offgrid or portable operation. Use scenarios Offgrid charging station: connect a solar panel or other DC source to the module's terminals, then use the USB port to charge multiple mobile devices at the same time. The stepup functionality helps maintain usable charging voltage when input levels vary. DIY electronics bench: power small electrical equipment and digital devices from a DC source. The screwterminal design makes wiring straightforward for temporary setups or test rigs, while the USB output provides convenient charging for portable devices. Laptop power or solar regulator: use the module as a laptop power supply or to regulate solar panel output for sensitive electronics, allowing operation in locations without a traditional AC power source.
