eufy Security Rechargeable Battery Pack with USB-C, Quick-Release Battery Pack, Long-Lasting Backup Power, 6,500 mAh Capacity, Easy to Install and Remove, Compatible with Video Doorbell E340/C31

Works great. Nice to have a 2nd battery so there's no downtime.

I really like that you don't need a subscription and all the videos you want are saved locally. It was easy to install and the image quality is excellent. The added feature of a second camera that looks down is great for checking for packages. It connected smoothly to my Echo Show so I can see who is at the door even if my phone is not handy. It is a great value and well made, as all the products I have used from Anker. I am running with a battery since the wiring for my old doorbell went bad. So far, battery life is ok, and it is easy to recharge. I would recommend a spare battery to minimize down time.

Great battery, lasts 3 weeks on Balance Surveillance. Very satisfied with this purchase.

I like my Eufy E340 doorbell camera, but it does drain the battery pretty quickly. With this extra battery I can easily swap the battery when needed. It only takes a minute to swap - use the release tool to remove the doorbell, swap the batteries, snap the doorbell back on the wall. Quick and easy, much more convenient than changing the battery on-device

Item works well just pricey compared to generic

Extra batteries are a must. Got the extra battery to switch out when the one in the doorbell needs charging. Eliminates the need for a downtime. Would be even better if the battery capacity was slightly higher. I have to change the battery every week. However, that is probably due to the higher traffic on my street.

I got this for my eufy 340 doorbell. I don't know if the same battery is used for other products they sell. The battery has a usb c port built into it with a cover. To charge just plug it into the included cable and the usb A end of the cable into a relatively recent 5v 3A usb phone charger (or any of the hundreds of chargers that amazon sells that can output in that range). There is a tiny led on the front, red for charging and green when complete. It took like two and a half hours to charge the battery and I don't know how much charge was on it when it was received. The battery must be installed regardless of whether your doorbell is wired into your house wiring, at least currently this is so. Glad I got the second battery, turns out I am getting a couple weeks off a battery while using the balanced setting in the doorbell settings. If I turned off motion detection completely I'd get more life but I like using it for the package detection and notification so in case there's any question about a delivery I've got the video of the delivery person.

Nice to be able to just change the battery. Last, okay, it depends on the traffic.

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.

Perfecto como repuesto para mi eufy 340

Bra produkt

Past perfect en is erg gemakkelijk om te hebben. De nieuwe deurbelcamera verbruikt nogal wat meer dus nu kan ik ze gewoon snel wisselen. Ideaal dus.

Cette batterie de rechange vous évitera d'attendre plusieurs heures avant de pouvoir remettre en service votre visiophone.
