eufy Rechargeable Battery Pack with USB-C

I bought this as a back-up battery for the E340 Video Doorbell so I could keep using the doorbell while one battery is charging. I found that if you use the motion detection settings on high along with the other settings maxed out the batteries only last a week or so. I ended up hardwiring my doorbell because I wanted the highest video resolution and motion detection possible without having to change a battery every week.
If you have the doorbell settings set to minimum and don't have a lot of traffic in front of your door, using only battery power would probably work great. But because of how I wanted the doorbell settings, it drained too fast. The battery itself is a nice lithium-ion battery that I never had an issue with. I still kept it because the doorbell doesn't work without a battery installed, and I like having a backup just in case.

Great product holds charge well , easy to change

Great battery! Nothing beats the manufacturer's authentic parts. I had a supposed "compatible" non-Eufy brand battery and it started malfunctioning within a couple months.
I will only buy Eufy brand products in the future when I need them.

Last along time

I have a couple of the security cameras along with the home base and decided to replace my old wired doorbell with this model. Installation was a breeze, instructions were very good. Integration into my system using the app was super easy. Very happy with the capabilities and the piece of mind it gives me. Alexa integration was seamless.

super!

I would definitely recommend buying the battery as the only down time is the time to pop the charged battery in
