| Battery | 10,000 mAh rechargeable | Eight AA cells | Charging and replacement routines differ. |

What you give up
Every choice has a cost
If you choose eufy Security Video Smart Lock S330
- One rechargeable battery supports both lock and camera activity.
If you choose eufy Security Smart Lock C220
- There is no Apple Home Key support.
Recommendation switch
The decision flips if...
Apple Home Key matters more than fingerprint or video entry
Choose neither. Encode Plus provides Home Key with direct Wi-Fi in a replacement deadbolt.
What matters in practice
How to make the call
For a porch that already has a camera
C220 avoids duplicating video hardware at the deadbolt. If the current doorbell has a useful view of visitors and packages, a combined camera may add little. S330 deserves consideration when one device can serve both purposes at a suitable viewing height.
For power and charging
S330 rechargeable pack must support camera and lock use, while C220 uses eight replaceable AA cells. Published runtime estimates are usage-dependent and cannot be compared as a controlled test. Plan where the S330 chime bridge will plug in and how charging will be handled.
For a door that is often left ajar
S330 door-sensor auto-lock offers a different input from a countdown alone. Test the actual installed settings and make sure the bolt moves freely. A smart lock cannot pull a poorly aligned door closed or establish that an obstructed entrance is secure.
What this comparison cannot tell you
- Manufacturer feature documentation is used here. No burglary, battery-life or recognition-speed test was performed.
- Retrofit compatibility depends on the existing deadbolt and adapter. A matching door thickness alone does not establish fit.

Match countThe count uses the current product-to-need assignments for “See who is at the door too”, “Unlock with a fingerprint”, “Control it away from home without a hub”, and “Give family and guests a code”. A need with no documented match does not count.
Calculation noteThis uses the upper end of each published door-thickness range. Bore pattern, backset and lock type still need their own checks. 18 of 25 models have comparable published figures for context.
