## Questions & Answers

**Q: Is it compatible with the august doorbell cam pro (aug-ab02-m02-g02) ?**
A: what is the voltage requirements of the doorbell camera? if it is 24 volt ac then this should work... look at what the camera requires: voltage, type of voltage and amperage required... so if the camera falls within 24 volts AC at or under 0.2 amps it should work.

**Q: Is this wire stranded?**
A: yes it is a stranded wire.

**Q: Is this wire heat resistant or plenum rated (cmp)?**
A: I saw no such rating, and I wouldn’t run it internally

### ⭐⭐⭐⭐⭐ Power Source for Ring Doorbell
*by V***E on July 20, 2025*

AMAZON, this is why you get all of my MONIES. I FINALLY found the correct item to keep my Ring Doorbells charged without baboon to take them down every month to charge. I've bought solar panel after panel just to return them and I was at my wits end then I came across these. They work perfectly. Easy to install, just plug in any regular wall socket. No mos power supply. Durable, I got the 26in so more then enough wire length to run from Ring to plug.
