Aurora ★★★★★

Swapped it into the S330 when the first pack dipped below 20% and it charged right back up overnight. Having a spare 10,000 mAh means I never worry about losing video coverage mid-week. Battery life easily matches what the doorbell promised.

Ryan ★★★★★

The 10,000 mAh capacity is no joke—I charged it once, popped it into my smart lock, and the battery level barely dropped after two weeks of heavy use. Swapping it in took less than a minute, and I love having a spare ready so I never get locked out.

Daniel ★★★★★

Swapped this in when the original pack dropped to 20%, and the 10,000 mAh capacity gave me a full two weeks of doorbell and lock use before I even thought about recharging. It clicks in snug and holds the charge well, so no more juggling cables mid-week.
