How are these rated for handling the elements? Not planning to do any riding in really severe weather, but if these are exposed and it drizzles/rains on the bike during a work day, is there any risk of damaging equipment?
The product page listing in the original post says IP67, which agrees with other outlets and was bragged about by DigiNow when they were producing 3.3kW-unit-based charging systems. So that's a really good rating test for dust (6) and water (7) per
https://en.wikipedia.org/wiki/IP_Code . This does seem to be the case from ownership reports and in my usage.
However, the 12V and CAN wiring is known to have electrical vulnerabilities, that is that the internal circuitry isn't fully isolated from electrical faults induced from the outside. That means that the cooling fan wires, if shorted, could "brick" the charger, and I've personally seen some heating of CAN wiring on a 5-unit DigiNow system I was using while on the road.
So, there is this electrical sensitivity that is worth minding, and it would be helpful to have a professional vendor with a lot of experience handle that for customers. But if you don't damage the wiring or run complicated setups with failure-prone elements, these chargers are fine for keeping on vehicles. (Especially compared to server power supplies or Eltek Flatpack units with a higher power density that are only designed for controlled, dry, stationary environments.)
