Thank you for your inquiry. I am slightly confused by the nature of this inquiry. It appears your device is a Qi Wireless desktop charger that plugs in and uses an AC power source. Does the host device have a battery? If yes, does the host physically connect to the client device and can be used in such a manner where it would be in close proximity to the user? How does the host physically attach to the client device?

Good day, this WPT device can used as portable and mobile condition as with internal battery, if charge from AC power can used as Qi wireless desktop device while also can charge with battery as portable. The device was used as power bank charge and device physically attached the client such as mobile phone handle by hand. I attached external photo to you maybe help you understand. Waiting for your information. Thanks for your attention!

From Water FCC Response on 04/03/2019:
Apologies for the delay. The test setup photographs show the charger plugged in for all tests, including those done at 0 cm. Is this the worst case? Was there any evaluation done at 0 cm without the charger being plugged in, to represent the portable exposure condition? The tests done at 15 cm and 20 cm are acceptable, however for the 0 cm case, some type of evaluation needs to be done without the charger plugged in, to represent the portable exposure condition.
