That only works with gear
which can use 12.0v - 15.0v, which is the range of voltages a typical house DC system (12v nominal) will experience.
Otherwise, you need a DC-DC converter for every item. Generally not worth it.
I do have 24v (my house electrics are 24v) chargers for my laptop
and 5v micro-USB stuff (IPad, phones, cameras, etc.). My computer monitor
is 13.8v and will run directly off the big DC-DC converter I have for VHF
. All these measures are pretty painless.
For the large monitor
(aka TV, used often for watching movies) I have a separate small inverter which I have not yet connected. On this summer's cruise
, I tended to leave the big inverter going 24/7 as there was constant need to run or charge this or that, so all these measures were probably somewhat futile. Incidentally, I had no problems with electrical
power although we were at anchor
and off shore power
most of the month. A good generator
run once a day was generally quite enough. So on my boat, at least, saving that last bit of power by scrupulously powering everything only from DC power does not seem to be worth the hassle. YMMV, of course.
