This product is a constant voltages power supply and cannot be used in products that require constant current, such as charging batteries or driving LED lights with constant current. 2. The power supply can be and regulated, and can also be boost and regulated. For example, the output is 19volts, and the input 12volts-90volts can be stable at 19V output. under boost conditions. The load capacity will be reduced by half.
