I live on a boat and run my S9 mostly from DC leisure batteries using this converter. It is bulky, but of sturdy construction. I find it tends to use roughly 0.1v per night. When camping I take a single deep-cycle leisure battery, a crocodile clip attachment to 12v cigarette lighter style outlet and plug this converter into that. It works just as it should.– 30-Jul-2018 –
I often travel overnight as the passenger in a car, and am aware that my snoring can be distracting and annoying for the other occupants. This device works well with the 12v Socket in the car. However, it means having to take two transformers, due to it's not being compatible with a 240v to 12v conversion plug. So whilst this does the job for which it's intended. It does add to what's needed in the bag.– 22-Oct-2017 –
