" Off grid with CPAP "

Purchased the DC / DC converter for my ResMed S9 CPAP machine to allow me to run the machine from a 12V caravan battery. I used the converter with a 12v 115ah leisure battery purchased from Halfords. I have just used this combination for a week in an off-grid cabin and it worked great. I did not use the CPAP humidifier as I feared it may drain the battery too quickly. The converter worked brilliantly, the on/off switch in the included cigarette lighter socket was a useful feature.I would recommend buying one of these converters for anyone spending time away from a mains power source. Only negative is the price, which is horrendous, compared to generic DC/DC converters. Jim April 2016
