C220 vs E31: Key Specs
power source
The C220 uses eight AA batteries for power, delivering up to eight months of operation. This standard setup is simple to replace but requires periodic battery swaps. The E31 features a 10,000mAh rechargeable battery that lasts up to 14 months. It includes a power save mode and low battery alerts. You can also use a portable charger to unlock the door if the battery dies completely. The rechargeable option offers longer intervals between charges and eliminates the need to buy disposable batteries.
connectivity
The C220 has built-in Wi-Fi, allowing direct control from anywhere via the eufy Security app without a bridge. This simplifies setup and ensures remote access is always available. The E31 does not list built-in Wi-Fi. Instead, it relies on Apple Home or other hubs for remote control. This means you need a compatible hub in your home to unlock the door remotely. If you already have an Apple Home hub, the E31 works seamlessly. Without a hub, remote features may be limited compared to the direct Wi-Fi connection.
smart home compatibility
Both locks support Alexa and Google Voice Assistant for voice control. The C220 also integrates with the broader eufy ecosystem, allowing routines with eufy doorbells. The E31 adds native support for Apple Home and SmartThings. This makes the E31 a better choice for users deeply invested in the Apple Home ecosystem. It works directly with Siri and Apple Home hubs. The C220 focuses on the eufy app and Alexa/Google, lacking explicit Apple Home integration. Your existing smart home platform should dictate this choice.
unlock speed
The C220 unlocks in less than one second using fingerprint recognition. It uses self-learning AI to improve precision over time. The E31 is faster, unlocking in under 0.3 seconds. This near-instant response reduces wait time at the door. Both locks improve fingerprint recognition with each use. The E31’s speed advantage is notable for quick entry. For most users, both speeds are acceptable. However, the sub-second performance of the E31 offers a slight edge in convenience and efficiency.
warranty
The C220 is BHMA Grade 3 Certified, indicating durability after over 100,000 lock/unlock cycles. It operates in temperatures from -22°F to 158°F and has IP53 waterproofing. The E31 offers an 18-month electronic protection and 36-month mechanical coverage warranty. While the C220 highlights its certification and environmental resilience, the E31 provides a longer explicit warranty period. This gives you more time for manufacturer support on electronic components. The C220’s data does not list a specific warranty duration, focusing instead on build standards.
