another nail in the coffin of overpriced EV Charging Station vendors

That's cool and as you say healthy competition but that box looks too small for all the guts and I don't like the earth bus flapping about. It must get warm in there as well.

nothing using much energy in there... the electronics requires a few milliamps at +/-12V and the contractor and power supply dissipate little heat.... I've had one of these on continuous test for a couple of months and the box is no warmer than ambient temperature.
