    Connecting to a solar panel
    • Remove any adapter from the solar panel cable or extension cable if there is one
    • Plug the solar cable into the female plug on the back of the Nanuk case, pushing it all the way in so that both ridges on the solar cable are covered
    Connecting to the battery on the inside of the case
    • Connect the internal cable into the Voltaic battery (V15 or V44 Battery recommended)
    Customizing Foam Insert
    • Lay battery on top of full foam insert to plan where it should go
    • Use a sharp knife / box-cutter / scissors to remove foam around the edges of the battery so it will fit securely
    • Once the edges are cut, use horizontal cuts inside the foam to remove the entire layer foam from the insert
    • If battery is positioned on top of the foam (recommended) cut an additional cavity underneath the battery to store your cell phone

    • Don't Hit the Water Without It by 2018 Baikal Headwaters Expedition (on 1/8/2019)
      I brought this case and a 9-watt charging kit on a 60-day, 1,000-mile journey from the uppermost reaches of Mongolia's Delgermörön River to Russia's Lake Baikal. It easily withstood many hours of rain and snow (the river was flooded a good proportion of the time), allowing me to leave the solar panel out to catch any stray moments of sunshine. My only regret was not buying the longer cord . . .
