We immediately bought a station: a solar panel and a portable battery. We decided to take a set, as one technique complements the other. Used so far only in the summer, when we went out into nature to relax. In our daylight hours, the panel usually charged 90-100% of the battery. We tried to charge from the very morning and hours until 16-17, since after the sun was not so intense. And then they connected all the necessary equipment to the battery: smartphones, a laptop, a lamp. Thanks to this, we were in touch with electricity and watched movies on a laptop. In winter, we have not yet had time to test it, we are just getting ready. The equipment is excellent, it justifies its price completely. We consider it an indispensable thing for camping with tents.
