And the cheap ones, are rarely reliable OR anything near pure sine wave.
Fully agree on all points.
I installed a couple of USB sockets in the cabins so we can keep all the gizmos charged. In my previous boat I also had a DC-DC stepup converter for the laptop
but that has been replaced by a tablet now.
The boat came with a cheap 300w "near sine" inverter that was pretty useless, even smaller appliances
would overload it, many electronic devices either don't work or don't charge. Some appliances
do work but make funny
noises, run at lower speed or get hot.
Completely useless device.
I suggest to get a pure sine wave, that way you are sure you can run anything within the inverter's power limits and don't run into surprises. How big depends on your needs and your battery
We now have a 1000w pure sine inverter made by sterling power , found an older unused unit on ebay for just 180 Euro.
