[QUOTE="bazza2210, post: 296596, member: 1112"] I have the same issue with my 12v fridge in the car, it is a companion. What happens is the high in rush current on fridge startup causes an increased voltage drop over the length of the lead and the fridge will not start because it thinks the battery voltage is too low. My solution was to buy from china a buck boost regulator. this regulator is a little different in that as the input voltage reduces it will always maintain a constant output to your device (settable via a small pot on the cct board) , in other words it draws a little more current from the battery to maintain that constant output voltage to your device. it is 98% efficient according to my tests. It is only good up to 10A or so. It can be used down to 5v on the input and up to 24 volts on the output and the thing to remember is that instead of your device showing degrading performance as the battery voltage decreases it will go fine up to the point that the regulator input voltage is too low and will turn itself off and that is between 5 and 8V.
