    When checking ACDC adapters to see if it's good, they all read 2-5V
    above their rated voltage. Is this normal? This is with no load on
    them. There's no way to check amps without having them plugged into a
    device to create a load, correct?
  2. Correct. Most AC to DC adapters are unregulated and reach specified
    voltage only with the specified load current.
