External batteries for laptops and not only
I recently realized the need for fast, long-term movements in space without access to the power grid, compared this fact with the length of life without a network of accumulators of my laptop, and decided to consider the option of acquiring something extra and external. Search results below. If someone has any additions / comments, they are most welcome.
Specifications are translated / copied from locations, so there is a different set everywhere.

Here you can look at all available models, but some (UC-3 and UC-4) are no longer sold. But there are still different solutions separately for mobile phones and other trivia. And - both options are quite expensive.
