We've been designing some mini-solar charging stations. I saw this system for sale at Costco for $99
Goal Zero Switch 8 & Nomad 7 Kit | Complete Solar Kits | Goal Zero
The problem is, this thing can't fully charge an iPhone off the battery.
I have a design which could charge up to 6 iPhones off the battery plus it would have a 12VDC outlet. The battery could run a LED flood lamp (75W equal) for 5 hours. Solar panels would be 15W. You could run any 12V car accessory with the unit.
Is $99 a breakpoint for you? Could you afford $199 for my version?
How much is weight an issue? Would 5 lbs be too much for everything? Would you pay $279 for the unit to weigh only 3 lbs?
Is UL rating important to you? The Goal-Zero unit is not UL rated.
How about made in USA?
Our present product is $750/$999(light)
