16 AWG (American Wire Gauge) wire and the same or higher electrical rating as
the device being connected. Use of improper extension cord could result in risk of
fire and electric shock. Three prong to two prong adapters should not be used. Use
of three prong adapters can result in improper grounding and present a shock
hazard to the user.
Ensure the pins of the extension cord plug are the same number, size, and shape as
those on the charger.

the charger AC cable plug or the extension cord plug.
