This is the one I ordered when I got my Volt in March. Nothing fancy, has held up well to Oklahoma spring showers and hail in my carport so far. My new pup even chewed the rubber cover off of it before I was able to stop her, catching the cord in a few places. Not quite 2 months in, so not able to vouch for longevity yet

I bought this charger when I installed my 14-50. Have been using it daily for over 2 weeks with no problem so far. Its been plugged in and left since I finished the outlet, which is is in my carport, not a climate friendly garage. Have not seen anything weird with it yet.
