Although the Anker can have two sockets and suggest two power feeds I imagine drawing two supplies from it will degrade the amount of power for the all important PAW unit.
On another thread I've been warned about powering my dongle from the PAW USB unit but after 6 months of using it it seems fine.
Just researching how do not do that on another thread however.
My power supply to the PAW unit has been changed a few times and the latest seems the dogs kahuna, link below.
It's a AINOPE 4.8A, 2 x 2.4A
