Review on Arlo Certified Accessory - Solar Panel Charger (2018 Released) for Arlo Ultra, Ultra 2, Pro 3, Pro 4 and Pro 3 Floodlight Cameras: Weather Resistant, 8ft Power Cable, Adjustable Mount - White VMA5600 by Steve Collins

If you need to install the Ultra in an area with a lot of object or people moving, DO NOT BUY THIS. Because it can only charge your Ultra with a few percent capacity per day. If you plan to use Ultra for such a remote location with less traffic, it will work fine for you. This panel is only "2W", EXPENSIVE. You can buy a flexible solar panel that has a USB connector and a 7m 40us cable and you can enjoy CVR recording all day long, not this overpriced panel.
