When you're living abroad, especially far outside of cities and towns, you can bring everything with you -- including internet connectivity and power.
It's expensive, but you can get your own internet connectivity via satellite in most countries. And if the sun is shining, you can get your own electricity.
There are many mobile solar power products on the market. Most of them aren't big enough to even fully charge your phone in a day.
That's why I love the Goal Zero Boulder 100 Briefcase. It's a $300 solar panel with a handle, that turns it into a large briefcase or portfolio.
You plug it into a Goal Zero Yeti Portable Power Station, which can be had for as little as $200, and you'll never need to plug into an outlet.
The beauty of the Gastronomad lifestyle is the freedom to live anywhere. The Go Zero charger is one way to include any off-the-grid location as well.
Here's all the stuff I use and recommend. - Mike
