One of the biggest challenges of going north into the Arctic is getting sufficient power to run the cameras in the extreme cold. I'm always surprised by how quickly the batteries drain in the cold.
This year I'm taking 2 thin external power packs that will be able to power the video cameras without draining their internal batteries. The power packs can then be charged overnight (or during the day if we're hunting the aurora) in the cabin.
We're always advised not to have electronic appliances plugged into the ships' electricity supply while we're not in the cabin in case they overheat or cause a fire, something to be taken very seriously !
On the countdown to sailing, the power packs are already being charged up and will only need a small boost before we leave.
