The present disclosure describes various alternative embodiments of plug force testers, in particular devices well-suited for testing aircraft ground power connection plugs. The disclosed plug force testers provide a fixed, well-supported position for test pins on which a plug is inserted, which can be positioned to correspond to a height or orientation of the pins in an actual aircraft. Embodiments described also may include means for preventing excessive force application during testing.
