Let me start by saying this solar panel mount has been a lifesaver for my Blink Outdoor 4 camera. No more climbing ladders every few months to swap out batteries - that alone makes it worth every penny.
The installation was ridiculously easy. I had it up and running in under 10 minutes. The adjustable ball head is genius - lets you position both the panel and camera perfectly. Mine gets about 6 hours of direct sunlight daily, and even after a week of cloudy Seattle weather, my camera kept chugging along.
The waterproof design is legit. We've had some serious downpours recently, and the unit didn't flinch. The monocrystalline panel seems way more efficient than cheaper alternatives - I noticed faster charging compared to my neighbor's generic solar setup.
Now for the not-so-great parts: The lack of charging indicators is frustrating. Like several reviewers mentioned, you're flying blind on whether it's actually charging. I also had a spider problem (they love nesting under the cover), but a quick spray of peppermint oil solved that.
Pro tip from experience: Make sure you REALLY push that USB-C connector all the way in. I made the same mistake as one reviewer - thought mine was broken until I realized the connection wasn't fully seated.
After 3 months of use, I can confidently say this eliminates battery anxiety for Blink cameras. Just be aware it's not completely maintenance-free (spider checks!) and requires proper sunlight exposure to work optimally.
