Reconyx Solar Charger 10 Watt

Unit is well thought out/engineeried for use in the wild outdoors. Impervious to weather and curious cows. Fits the Tee Post perfectly. Expensive but pays out when in unlimited use. Lithium batteries are expensive.

Keeps camera charged year round, 3rd one on 3 different cameras and all work great.

Solar panel keeps my camera over 12 volts even without having direct sunlight.
