Hi there, @Eaug9th! To best ensure that your Solar Charger is providing an effective charge, check out our Community post about battery drain for tips on optimizing battery usage. Most importantly, please ensure the Solar charger is receiving several hours of direct sunlight daily. Once you’ve optimized your device for battery preservation and allowing the Solar Charger to be most effective, please monitor the battery level over time, especially once it reaches below 90% as a charge will be most noticeable. I hope this helps!
