here's an idea:

"tmack: Your quad folder is all done. It will come with a 700ma charger , 12v socket (using 3xusb->12v socket) and a 4.4amp usb connector (for when the sun isn't shining but you still need to charge stuff fast

and a simple nimh charger ($199) For anyone else interested, I normally make this up with just 2 usb ports (2.2amps each) with one being Apple and the other android/standard, but using 4 ports gives the option to charge a laptop if its happy on 20v and you (or ask me) can make up the lead. I'm also sending the ordered $15 18650 storage box for charging stuff when the sun has gone in. Hopefully I can get this in the post to you tomorrow and will send tracking. If I can't make tomorrow (unlikely I can't make it) , it has to go Tue as its a UK holiday. The panels have removable plastic on to keep fingerprints at bay, which you can remove to make it look nice like the mini folder.
doctordun: I'm still playing around with how best to make the mini-folders - you are welcome to the one in the pic for $42 delivered. Its not perfect as the Velcro isn't as aligned as it should be, but its very light and minimalist -weight is 250g and size is 15cmx18cm. I think when I finally make these a standard offering the price will change a little (perhaps $49 with a lead / charger of some sort) and I'll make it slightly larger at 15x19cm. "
I've e-mailed him about a ready-to-charge-our-vape-batteries solar solution and his response was positive.
He'd be willing to work with us if there's enough interest in a 12v (Intellicharger or whatever) ready output device.
I'm sure if we'd like a standardized solar charger for our batteries type product we could get a decent price.
I think these would work fine with a basic dual panel setup -

I'm awaiting feedback from him.
I
will be getting something from him.
I'd like to see if there's any interest in designing a special solar package for us vapers first.
Any other
real interest in a solar panel charger here?
