I finally hooked it up to a disconnected battery in a car that wasn't in use. Voltage without charger was 12.40, with charger it was 12.40. Reconnected battery and charger, and it still measured 12.4 volts next day (my Outback draws about half an amp). Only problem is the suction cups won't hold worth a @#$% for any significant time, and I have the black and blue toe to prove it!One caveat: I would make sure to disconnect solar charger before disconnecting car battery. Otherwise you may fry the car's electronics. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works like a charm *by F***N on Reviewed in the United States on August 2, 2023* Left it for a month on my car and my battery was at 100%.
