    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...

    I am very happy with this product as it allows me to charge my lipo battery packs that I made from 18650 batteries from 4.2v to 18v with easily adjustable voltage and current. Make sure you check output voltage with multimeter as calibration could be required , mine didnt and always disconnect battery first to prevent charge back to unit.

    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
