eufy Security Rechargeable Battery Pack with USB-C, Quick-Release Battery Pack, Long-Lasting Backup Power, 6,200 mAh Capacity, Easy to Install and Remove, Compatible with eufy Video Doorbell E340 &C31

I swap this over when the battery which came with the door-cam needs recharged, keeps the door-cam constantly active. I get around 22 days from each battery and they recharge reasonably quickly. Well worth the money to have another battery.

I just picked up 2 of these for £19.99 each at what I thought was a steal! My doorbell was running low on battery endlessly and having to recharge all the time but I suddenly realised the battery was replaceable. I have to give props to Eufy for keeping it subscription free and making it easy to replace a battery and save spending money on a new doorbell (looking at you Ring and your anti-consumer tactics). Super easy to install and very pleased!

Works well as the replacement for the one that is currently in the bell unit. No down time due to recharging.

I am used to Ring doorbells and their batteries generally last a fair amount of time between charges. After switching to Eufy, I noticed the included battery drained much faster than I expected. I bought this spare so I could swap them over and avoid any downtime. It does exactly what it needs to do, it charges normally and keeps the doorbell running, although the battery life still feels noticeably shorter than what I was used to with Ring. Swapping batteries has become a fairly regular task, which can get a bit inconvenient if you rely heavily on your doorbell for security notifications. The build quality seems good and the price is reasonable, so it still offers good value overall. Anyone coming from a different brand with longer lasting batteries should just be prepared for more frequent charging. Ultimately, it gets the job done and provides a practical backup for when the main battery runs low. In the future I hope to hard wire my doorbell to avoid constant swapping, but as a spare battery, this is a solid option.

Brings peace of mind. Clear camera footage. Charges easily. Happy with it.

Great battery pack — easy to install, charges well, and holds power reliably. It’s made a noticeable difference to performance and gives real peace of mind. Solid quality and well worth it.

Solid piece of kit well made does the job backing up the original battery.0

This will come in handy, instead of waiting for the single one to charge. Good price,

Purchased as a secondary battery so that I can always have one charged up and ready to go when the other has run out of charge. I usually average around one month of use per charge, but it varies depending on how much activity occurs to trigger the camera or it’s light.

Bien utile quand on utilise l’appareil en mode indépendant.

Perfecto como repuesto para mi eufy 340

Bought this as a spare because the battery lasts about 3 weeks

super cool 2e batterie pour moi jonglé avec la 1er, et fonctionne bien
