  • We have an old auto battery charger and I am curious I cannot find any information on the charger itself.

      not much its only meant for 1 hour of charging at a time just enough for road trips not to leave stuff in your car.

    2. Don E says:

      amps X110 volts = watts (eg;10 ampsX110=1100 Watts per hr.)

    3. Ironhand says:

      Depends on the charger, and the charge rate.
      It is pretty difficult to tell you, because a small trickle charger might use something in the area of 150 Watts while the larger bench type chargers might use 10 times that. A full sized floor charger could draw as much as 25 amps.

      Does this give you a ballpark figure?
