AVD1001 Wired, but with battery power supply

[Smash_MD]

Hello! So, I bought this doorbell at local reseller and even though it is wired version I want to use it with external batteries. Specs saying in needs 16-24v and I saw an info here about 1 amp requirement. My intention is to wire it to two cr9v batteries which will give me nominal 18v and most of the battery lifespan they operate at 8v, which will be 16v in sum. But rated discharge current for those batteries are 900mAh. Will this work? Cause I've already developed custom case for this Doorbell with the slots for this two batteries to print on my 3d printed and now I'm not sure if I have to wire 3 maybe?

The spec says 16-24 vac (low voltage AC).  Batteries are DC, so this won't work.

There are low voltage AC power adapters you can purchase, which will work if there is power nearby.

Thanks for saving me from magic smoke! Can't find any AC adapters which aren't cost a fortune. Seem like I will throw this doorbell back to the market cause I see no way to arrange power supply for this thing for not double the price of itself. I suppose trying to save some bucks on not buying wireless version got me here.

There are quite a few cheap plug-in doorbell transformers. A quick search for "transformer for ring doorbell" on Amazon got me this one and others:

I'm not in US neither in EU, so anything apart local shops would be pricey in terms of shipping. And the one you've shared have 500mAh power and in other thread I saw an info about 1 amp requirement. But anyway thanks for the hint, I would try to google doorbell specific transformers, maybe they will come cheaper.

Actually, using "Doorbell power adapter 24VAC" request I was able to find led lamps adapter 24VAC 2A for less than 5$ from reliable local marketplace, thanks for the suggestion!
