Actually this is completely the opposite. youi can't charge it.

even charged with the scales,or pre-charged do you come back and double
check in warmer temps?

i did transport refrigeration straight outta tech school and my service
manager never once told me to have a recheck(not like a customer from
texas,or wherever, would travel back for a check up).

did three years with him, and never wanted to do refrigeration again....
