Ok my north slope caribou/ grizzly hunt i got stuck an extra 7 days due to weather..i went through all of my battery packs(4). Between reading on my kindle app and texting- checking weather on my Zoleo i burned through them all. The day i got picked up i didn't know the plane was coming.
Solar was a complete waste.
On my goat hunt last year i took 6 battery packs. I only used 1 as the weather was much better and i got picked up after only a 2 day delay. Solar might have worked on that hunt as i was in short sleeves the whole time.
If you can't bring them with you i will let you use as many as you want when you come through. Just let me know.
