Pair Your Panel With a Power Station

See estimates for how quickly your solar panel can recharge Yeti power stations.
Note: Requires MC4 Solar to HPP Adapter Cable (98014) to plug directly into a Yeti. Sold Separately. Charge times will vary based on elevation, temperature, time of year, and angle/position of the panel.

Tips & Tricks for using solar panels

        1. Your solar panel collects energy, but does not store it. In order to use it, connect it to a power station, or charge your devices directly with the cables attached to the panel.
        2. Adjust your solar panel throughout the day for optimal sun exposure.
        3. Don't forget that you can still use your panel on a cloudy day, it will just be less efficient.
        4. Use ground stakes to secure your panel while you're away.
