Blink Video Doorbell (2nd Gen) vs Eufy Video Doorbell C31 (with Battery Pack)

The Eufy Video Doorbell C31 (with Battery Pack) wins overall: it is better rated, shoots 2K, works with more platforms and records locally with no fee. The Blink Video Doorbell (2nd Gen) is cheaper with a very long AA battery, but it is HD-only, Alexa-limited and its new module drops local storage.

Storage and resolution. The Eufy Video Doorbell C31 (with Battery Pack) records 2K locally to microSD or a Eufy HomeBase with no subscription, while the HD Blink Video Doorbell (2nd Gen) removed local storage on its new Sync Module and effectively requires a paid cloud plan.

The Blink Video Doorbell (2nd Gen), rated around 2 years on 3 AA batteries. The Eufy Video Doorbell C31 (with Battery Pack) uses a quick-release rechargeable pack (and ships with a spare) whose real-world life owners find shorter, though both can also be wired (the Blink still needs its batteries when wired).

Only the Eufy. The Eufy Video Doorbell C31 (with Battery Pack) stores footage on microSD or a Eufy HomeBase with no monthly fee. The Blink Video Doorbell (2nd Gen) no longer offers local storage on its new module, so cloud recording requires a paid Blink plan.

Buyers who want 2K video, subscription-free local recording and broader integrations (Google, Alexa, Home Assistant), especially those with or planning a Eufy HomeBase. The bundled spare battery and automatic replies add to its fee-free appeal.

Budget-focused Alexa or Blink households that want a very cheap doorbell with an exceptionally long AA battery and customizable motion zones, and who do not need 2K, local storage or platforms beyond Alexa. It is the low-cost, low-maintenance pick.
