So Ive done a trial two nights in a row, using a 27k power bank, averaging 23 watt draw over 2h 45 mins, with a spare device running 10 YouTube videos at once to simulate data usage.
Snow melt turned off.
And that is down to 30 percent battery on the power bank, the power bank seems to draw really fast after that testing on recharging torches etc and will be fine with a small solar panel for topups.
Its a pretty good system for what it is, and what I intend it for, simple and easy to use for the less tech initiated.
The hunters I hunt with all carry Epirbs anyways for emergencies, I view it as no real difference to mountain radio or inreach/ sat phone
Power it up, connect to the network and make a standard call via wifi
