Amazon was having a dale this weekend and I decided to buy an Ecoflow River 3 Solar Generator.
It's the smallest in the Ecoflow line at 245wh, but with the sale it cost me about $150 before taxes, so half the cost of the Jackery that Walmart stocks locally.
I plan to buy a solar panel for it in the next few weeks, but for now I am seeing how it handles being on my cars 12v connection while powering a small laptop.
So far so good.
