I have bought “Video Doorbell 2Gen”
Transformer for continuous charging installed in my house is (12 VAC, 8VA, 50/60Hz). I found that battery charging is extremely slow (6 hours only 2%). Can I use this transformer or should be replaced? if I fully charged the battery, is it ok to use it without replacing?

Hi @Johnny_Kourieh. There are a few factors that can determine the way your Doorbell charges. Hardwiring serves as a trickle charge that should maintain the battery level with average use. Depending on the number of events/Live Views per day, the amount of charge you are getting is consistent with what is expected. I hope this information helps.
Hi Tom, Thank you. So I consider no problem to continue using installed transformer (8VA) since can feed doorbell but with slow charging, right?
Hi @Johnny_Kourieh. Transformers typically have 2 ratings, VAC and VA. A transformer with the rating of 8VA (Volt Amps) would not be sufficient. A transformer with 8VAC (Volts Alternating Current) is sufficient. You need both ratings to have a functioning doorbell. You can find out more about the power ratings here. I recommend a transformer with 16VAC and 30VA. This transformer here meets the necessary requirements.
First of all, nothing is mentioned in your website regarding minimum VA, Only mentioned max 40VA. “charging (8-24 VAC, 40VA max, 50/60Hz)”
So how to know that requirements are 30VA.
Now I see that my device works good if temperature more than 3C and get 100% chraging. Less than 3C battery goes down directly to 78%. That exactly happened two times this week. It is very strange that two times get same percentage 78%.
Design flaw pure & simple. I was devastated when I realised I wasted my time ‘hardwiring’ the device. I’ll never buy another Ring product again.
