Trying to decide if I should get a HPWC or a JuiceBox. The JuiceBox could at least be used by other vehicles (I do have a Zero motorcycle). And I could get the 75 amp one if I ever decide to upgrade the onboard charger. But it's $800 compared to $550. The 40A JB is $599, but I liked the HPWC because I could wire it to be up to 100A if I wanted. The JB also seems to have some cool smartphone features, etc. Thoughts?
