I'm off on a 5 week climb of Ama Dablum this month and looking for some advice on solar panels. I've not had much experience with solar panels, so I'd like to ask for some advice.
The Goal Zero Venture 30 Solar Kit seems equally loved and hated. It holds up well in extreme conditions. However, there seems to be an issue with the micro-USB connector head coming apart from its cable for many. This is worrying in an extreme environment. The charging time doesn't bother me as it will take a long time to charge anyway with limited sunny November weather.
On the other hand, the Anker 21W appears to give good performance, but comes without a rugged battery attachment.
Q1. Which model do you think comes out on top based on your experience?
Q2. Has anyone had success using plain solar panels with a regular battery pack?
Q3. Any other brands that members swear by?
I'm waiting for Goal Zero to get back to me regarding the micro-USB issue. In the meantime, any practical comments based on field experience would be highly appreciated.
