Any suggestion for battery supply unit for trucks while reading/writing through OBD?
I have found this one.... http://www.ctek.com/pl/en/chargers/MXT%2014
I use c-tek mxs 25 for 12V and it is a good tool so far

I'd go with that. I use the CTEK MXS25 too. Gets some serious abuse being used in the rain and everything, first one lasted 4 years then had to be replaced. Great quality stuff.

Thank you for the reply.Can I use C-tek mxs25 on trucks?They usually use 24 Volts and mxs25 is suitable for 12 V.Am I wrong?
