My application is to run a CPAP machine from my 500wh Solar Power Station. These have lithium batteries with an unregulated output that swings from 12.5v down to 9v, which proved a problem when running with heated hose and water; It would shut off below 11.5v.With this regulator the CPAP machine sees clean power and runs wonderfully. The unit barely gets warm after hours of use. Now I'm set for camping and "Planned Power Outages".
