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.
What battery packs?
A single Shargeek 100 (25,600 mAh) will charge an iPhone about 6 times from dead to full.
