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 be hardwired.

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.
