I powered my smartphone off-grid with this portable wind generator. Here's how
Briefly

The Shine Turbine kit includes a turbine, stand, guy lines, pegs, and cables for easy setup. Initial setup may take longer in windy conditions, but it becomes easier with practice. Users can choose to charge an internal battery or use a power bank. Utilizing the turbine as a power bank is beneficial for portable energy needs, while separate power banks are more practical for base camps. This wind turbine serves as a solid backup when solar sources are insufficient, particularly in areas with unpredictable sunlight.
The Shine Turbine kit comes with everything you need -- the turbine, a stand, guy lines, pegs, and cables. Setting up the first few times took a bit longer than I expected, especially if you're trying to do it while it's blowing a gale.
Once set up, you have options. You can let the turbine charge up the internal battery and then use that to charge your devices, or you can attach a power bank to the turbine.
Using the entire turbine as a big power bank makes sense for odd top-ups on the move, but in a base camp setting, it's better to charge separate power banks and use those, keeping the reserve in the turbine for backup on still days.
I've tested dozens of devices over the past few years and seen the technology go from strength to strength. But I often get asked, 'What happens when the clouds roll in and the sun vanishes?' Living in the UK, the sun can be in short supply for much of the year.
