Indirect operation external power supply

means an external power supply that cannot operate a consumer product that is not a battery charger without the assistance of a battery as determined by the steps in paragraphs (1)(A) through (E) of this definition:

(1) If the external power supply (EPS) can be connected to an end-use consumer product and that consumer product can be operated using battery power, the method for determining whether that EPS is incapable of operating that consumer product directly is as follows:

(A) If the end-use product has a removable battery, remove it for the remainder of the test and proceed to the step in paragraph (1)(E) of this definition. If not, proceed to the step in paragraph (1)(B).

(B) Charge the battery in the application via the EPS such that the application can operate as intended before taking any additional steps.

(C) Disconnect the EPS from the application. From an off mode state, turn on the application and record the time necessary for it to become operational to the nearest five second increment (5 seconds, 10 seconds, etc.).

(D) Operate the application using power only from the battery until the application stops functioning due to the battery discharging.

(E) Connect the EPS first to mains and then to the application. Immediately battery was removed for testing and the end-use product operates as intended, the EPS is not an indirect operation EPS and paragraph 2 of this definition does not apply. If the battery could not be removed for testing, record the time for the application to become operational to the nearest five second increment (5 seconds, 10 seconds, etc.).

(2) If the time recorded in paragraph (1)(E) of this definition is greater than the summation of the time recorded in paragraph (1)(C) of this definition and five seconds, the EPS cannot operate the application directly and is an indirect operation EPS.
