As Rick said, the important part is the USB cable or possibly the Wyze power adapter.
Since the cable and power supply used to work, and because it is outside, it is possible the USB connections may have become a bit corroded, and are causing more voltage drop. Perhaps something as simple as unplugging and plugging the USB connector back into the camera will be enough to get it working again. If it is a bad connection from the wire to the USB connector in the cable itself, that isn’t going to be something that will be easy to fix.
If the original cable is still in place, the first thing I would try is to reconnect and see if it works after the contacts have rubbed off the layer of corrosion just by unplugging and plugging back in. If that doesn’t work, then try swapping power adapters with another camera. It is possible one of your other power supplies has a slightly higher voltage to begin with.
If that doesn’t work, then getting 110VAC (normal extension cord) to close the the camera is the most likely to work. Then you would be able to use the original USB cable with the camera. You should be able to use a cheap two prong extension cord with molded plastic ends, but you probably won’t be able to find one that long. Since there will be very little current (AMPs) going through the extension cord (0.25 AMP MAX), just about any extension cord will work as long as it has good connectors and the wall outlet isn’t worn out and the power adapter or extension cord doesn’t have a snug fit. The Wyze power adapter will accept voltage as low as 100VAC and still produce 5VDC out (it is a switching power supply).

I don’t understand why your other house current extension cords didn’t work with the Wyze power supply. Did you try plugging something else into them to verify that they had good working connections?
