50’ of cable plus higher power draw of 2 cameras will probably result in too much voltage drop.
See this regarding calulating the voltage drop:

uh thanks, but I lack enough expertise to even slightly comprehend the stuff in the link. So, 25 feet is max for one?
Like @HDRock said, try it. If the camera behavior is flakey, then you’ll know it’s too long.
I am currently using a 26’ cable to power 1 V2 cam, I have not tried chaining to at that length, I have also seen where people may have possible power issues with the PanCams so I dont know if i would try daisy chaining long lengths off of those

if you have a bridge on a camera, that draws extra power as well and the stock power socket does not do well with an extended cable and bridge. there have been a few people that ran an extended cable with a camera that has a bridge on it and had negative performance.

Sorry for replying to an old thread but I thought I would just note this for anyone else wondering. A Wyze v2 daisy-chained to a second v2, both with 25ft cables only kinda works. 50ft of cable is too much so the second camera “works” but you can see it flicker occasionally and it doesn’t record 100% of the time even though I have it set up to record continuously. I’m leaving it up for now, since it’s better than nothing and it’s the only way I can get a camera where I want one. Just hoping the low voltage doesn’t damage the camera. I’ll update if it does.
I don’t know your specific circumstance, but as a general rule running a 120V AC extension cord as far as you can indoors before going outdoors will help reduce the length of your USB cable. Also, heavier gauge USB cables help.

These should work correct?

I see no reason why the shouldn’t. As long as the micro end is rounded enough. The port on the V2 is recessed quite a bit. I had to pare down the plastic on the end of some that I bought.

Thanks. Mine keeps falling out.
Ordered. We shall see. $7.99 for 3 was good deal.
The cable ends on those cables are aluminum so if they don’t fit into the hole in the back of the cam, he won’t be able to pare them down unless the aluminum is a removable cover over plastic.

Oops. My bad. Hopefully they fit then.

I can gently remove a bit of aluminum.

Free returns so I won’t be out anything

My idea of gently usually consists of firing up the bench grinder. 
If you can’t get them to work, these cables and power adapters have been working great on my v2 cams:

Did you have to buy the wall chargers to or did you just elect to do that? Because I think they will charge is fine it’s just the very end of the micro USB cable where it goes into the camera has a slight bend in it and it keeps wanting to slide out if you move the camera very much

The included power adapter is only 1A I belive. Long small cables can have a significant voltage drop so a more powerful charger, like the 2A one linked above, makes sure the camera is getting enough power. I think. I don’t know if voltage drop can be fixed that way. I am not an electrical engineer. shrugs

A 2Amp power adapter will not be able to force more current than a 1Amp power adapter assuming they supply the same voltage of 5V. Generally the camera will demand the current it wants at the voltage it sees at the end of the cable. @gemniii recent experiment with voltage and current measurements at the camera shows that the camera demands some power and if there is a voltage drop on a long cable then the camera will draw more current. That seems normal to me as an electrical engineer.
