Blink Camera Battery Extension Packs

We recently purchased (3) battery extension packs for our Blink 4 cameras. The cams are located a distance from the house and difficult to access due to deep snow during the winter so we're hoping the packs will double operational time and afford an extended period time before needing battery replacement. *Note: We just installed the extension packs and not enough elapsed time yet to provide an accurate review.

Good buy

Perfect fit, added with a fine tip silicone applicator, some silicone grease between the 2 pieces for added moisture protection of the o-ring and battery compartment.

Perfect Battery Extension for Blink Outdoor-4 Cams

[This review was collected as part of a promotion.] I have several blink outdoor-4 cams that are in locations which are ridiculously inconvenient for me to change the batteries. These battery extensions have worked perfectly for many months now and are WAY less expensive than what blink charges. Great solution to extending the battery life on your blink outdoor-4 cams! Top recommendation. Also, my highest possible kudos to Wasserstein support for timely responses and complete solutions. PS: This review was unsolicited, and I did not receive any incentives / freebies etc. It's just my opinion.
