Can I charge Solio on a cloudy day and can it be left outdoors?
Yes, Solio will charge on a cloudy day, although less efficiently than when under clear skies. Cloud cover can also be too thick to allow enough sunlight through to the solar panels. Solio is engineered to be rugged and weather resistant, but it is not entirely weatherproof. Solio should not be left out in wet, rainy, or snowy conditions without a protective covering.
