VOLTAIC FUSE 6 Solar Panel w/2 batteries - $30 (Seattle)

I used this on my cross country bike trip to keep my batteries charged and as a convenient place to hold my spare batteries and various plug adapters for all my electronics.
Works great.
USB plug can be a bit loose ie jar loose from battery while charging so I always put some strong little legs of duct tape to keep that charging plug from bouncing out.
Have used in car and Kayak too.
Very light so you could backpack with it too .
Google it! Do not ask me if it's available - it is!!! If you do, I will ignore you due to bots mining Craigslist for phone numbers and emails.
Send me a NAME - TIME YOU WANT TO PICK IT UP AND A PHONE NUMBER- and I'll get in touch with you.
Seller is a really nice guy, but has cancer and is selling off all his toys.
I don't mean to be terse but I have a lot to sell and the bots and scammers are making it very difficult.
Google it for questions $90 on Amazon with one battery Life is to short to deal with that.
Especially now.
