It says, that adding an usb ar9271 wifi card to a pinephone is not feasible because the wifi card uses

to much power.

How much power is acceptable for an usb ar9271 wifi card to use?

I do not have extended equipment. I made the following arrangement.

One pc. Connected an usb power meter.

Connected an usb ar9271 wifi card to the usb power meter.

Started an youtube video. After that downloaded an ubuntu image. Distance to router about

10yards. One brick wall. Usb power meter displayed about 5.1v and 0.16a.

Is that much? To much to use on a pinephone?

The modem on the pinephone has an usb connection. About the modem, why is the power consumption

not a problem?

I know connecting an usb ar9271 wifi card to a samsung i9100 replicant phone is working terrible. Infrequent

disconnects, battery power level has to be above 90%. Thanks.
