“The Eufy website doesn't offer a dual-powered (batter and wired) E340 on its website, it seems you can buy only one or the other, but not together. Is this truly dual-powered or is it really just one or the other?”

It is dual. You can hardwire it or use battery power.
Sorry, there was a problem. Please try again later.The Eufy Smart Wi-Fi E340 2K Video Doorbell is dual-powered, but the term "dual-powered" can be clarified further based on Eufy's description. The battery-powered models have built-in batteries as their primary power source, but they can also leverage existing doorbell wiring as an alternative power source. Similarly, wired models are primarily powered by doorbell wiring. This dual power capability does not mean that a single model combines both battery and wired functionality simultaneously; rather, it refers to the option for battery-powered models to be connected via doorbell wiring as an alternative. If you're purchasing, the models are categorized individually as either battery-operated or wired, but battery-powered options can have the flexibility to use wired connectivity, should the wiring exist. Depending on your needs, you would choose one type and potentially utilize wiring for the battery-powered version.
