I'm currently making arrangements to store and work on a boat. The owner of the land can probably supply electricity, and I have offered to pay for what I use. I'm looking for a suitable meter that can be wired inline (probably into a conventional extension lead) to record usage. I would just use one of the myriad plug-in meters, except that these tend to forget the cumulative figures when unplugged, and that could be very inconvenient. I don't need ultra-accurate calibrated metering, and want to spend as little as possible on something I probably won't use again.
Any suggestions?
