Best solar panel and battery for Ring Outdoor Cam 2K and Spotlight Cam 2K?

Both cameras are compatible with the standard Quick Release battery and the larger Quick Release Ultra with a capacity of 10,000 mAh. If you want to power the device using solar energy, choose the official second-generation Ring Solar Panel USB-C with 4 W power output.

This is the same panel that Ring includes in Solar bundles with these cameras. Ring's compatibility list also includes a newer 6 W panel, but for now it is only available for pre-order in the US, so the 4 W panel is the one you can buy today.

Matching the power supply to the specific camera model

The cameras differ primarily in the number of battery slots. Check this before purchasing accessories:

• Ring Outdoor Cam 2K: features a single battery slot and a USB-C port to connect a solar panel or Ring's USB-C power adapter. The housing is IP65 rated, and the camera operates from -20°C to 50°C.
• Ring Spotlight Cam 2K: features two battery slots beneath the unscrewable bottom cover. The cover is secured by a single Phillips screw, and each compartment is spring-loaded. There is a USB-C port on the back for charging the camera or connecting a panel.

In the Spotlight Cam 2K, adding a second battery to the spare slot is the easiest way to keep the camera running longer without taking it off the wall.

Fun fact: The Spotlight Cam 2K housing has room for two batteries, but you will only find one battery in the box with the camera.

Ultra Battery vs standard Quick Release: differences

The standard Quick Release battery has 6000 mAh and comes in the box with both cameras. The Quick Release Ultra has 10,000 mAh, which is up to 67% more. This means you charge the camera less often.

The second difference is charging outside the camera. The standard battery has a micro-USB port, although in the Spotlight Cam 2K you can also charge it via the camera's USB-C port. You charge the Ultra directly via USB-C, and the cable is included.

The Ultra also features four LEDs that indicate the charge level in 25% increments. The Ring Charging Station is designed for the standard Quick Release battery, while the Ultra does not require a station.

Fun fact: The camera features a USB-C port, yet in 2026 Ring's standard battery still charges via micro-USB.

Below are only genuine accessories listed by Ring for these cameras.

Recommended batteries and solar panels for Ring Outdoor Cam 2K and Spotlight Cam 2K

Solar panel in practice and cold weather performance

Ring states that the Solar Panel USB-C 4 W requires 2-3 hours of direct sunlight per day. It comes with a 2 m cable with a USB-C plug, and the box also includes a barrel plug adapter for older cameras.

The camera often hangs in the shade, for example under an eave. In that case, the Ring USB-C 3 m extension cable comes in handy: you mount the panel where the sun shines, not next to the camera.

In winter, the panel helps less than in summer. The cameras operate from -20°C to 50°C, but Ring states that they work best at around 25°C. At temperatures near freezing, the battery lasts shorter.

Below freezing, the camera intentionally stops charging the battery. The panel will not help then, even in full sun. On freezing days, you sometimes need to remove the battery and charge it indoors via USB.

That is why a spare battery is useful for winter, which you insert while the first one charges indoors. Extreme heat also prevents charging: an overheated camera will not charge, and Ring notes that in direct sunlight under extreme heat, the Outdoor Cam 2K may temporarily shut down.

Questions and answers

Does the Ultra battery fit the Ring Outdoor Cam 2K?

Yes. Ring lists the Outdoor Camera 2K on the compatibility list for the Quick Release Ultra Battery Pack (10,000 mAh). This battery does not fit older Ring cameras.

How many batteries does the Ring Spotlight Cam 2K hold?

Two. There is one Quick Release battery in the box, and for the second slot you can purchase a standard Quick Release or Ultra. The camera also works on a single battery.

Which solar panel fits the Ring Outdoor Cam 2K?

Ring Solar Panel USB-C 2nd Gen (4 W): this is the panel that Ring includes with the Outdoor Camera 2K solar bundle. It has a 2 m cable with a USB-C plug. The newer 6 W panel from the Ring compatibility list is currently only available for pre-order in the US.

Does the Ring solar panel charge the camera in winter?

Only above freezing. Ring states that below freezing, the device intentionally stops charging. On freezing days, remove the battery and charge it indoors via USB, or insert a spare one.

Will the Ring Charging Station charge the Ultra battery?

The Ring Charging Station is for the standard Quick Release battery. Ultra does not need it: you charge it directly with the USB-C cable included in the box.
