    I mainly got this as i have plenty of 12v power supplies but not enough 9V rather than waste money on 9v batteries I got this and it works flawlessly. I now have another 9v supply for the cost of a couple of 9v batteries. My next project will be a dc bench supply but this will still get used as highly portable.

    I bought this to use as a charger for 12v SLA batteries. I used a variety of power inputs from a PC power supply 16v and 23v with a massive current, and finally settled on a 19v laptop power supply, using a diode on the positive connection to the battery to stop the battery sending power back to the unit, and a mini voltage display to show the slight reduction in voltage so it reads 13.8v at the battery and 2 amps current (which drops as it charges to full). Works a dream, and can be used for other projects too...

    Este es un cargador muy bueno. Lo probé con batería de iones de litio.

    I received it this morning. Now I'm finishing charging a small lead accu with a laptop power supply. I set the max voltage to 13V65, max current 1A. perfect

    Quite precise and easy to use. Very reliable after 2 month of use. Separate USB and standard output can be used at the same time. USB can be switched off. Output Current, output voltage and input voltage can be displayed.
