I have several V3 cams that are powered thru a 20ft male USB-A (Power Adapter Block end) to male microUSB (Cam end) that I got on Amazon. I have never had an issue with them. But, the manufacturing quality and construction is important. Cheap ones usually skimp on wire quality which will reduce current delivered and may very well affect performance when amp draw is high, like when activating the siren, a spotlight accessory, or the 2 way talk.
Another Forum Maven, @Newshound, did a lot of great testing on the effectiveness of long power runs over USB. The details are posted here:
Wyze does sell a 20ft USB-A extension cable that will work between the Power Adapter and the cord shipped with your V3.
