Mini laboratory power supply. Mini laboratory power supply, a good helper for homework with electronics. This mini laboratory power supply has short circuit protection. Regulated voltage from 0 to 25 volts. Regulated current from 0 to 3 amps. You can charge different batteries, including li-on. Green LED indicates idle or battery charging is complete. A blue light indicates that there is a load or the battery is charging. Red LED indicates overload. There is a separate USB output of 5 volts 2 amps. Output current and voltage depends on the power supply you connect. For a mini laboratory power supply I use an adapter from a 19 volt 3 amp laptop. All the items I bought on aliexpress.
