Did my ability to search for things intelligently on the internet die when Google search did or are there legitimately no personal umbrellas with solar panels and a battery pack? Like I feel like that would be an obvious thing, and there’s a bajillion beach umbrellas and patio umbrellas that have solar panels. How are there no personal versions for wandering around on a sunny day with portable shade that gets you a charged battery pack? Is this a thing and I just can’t find it or does it not exist yet and all of science has failed me in every way possible?
Sorry for the terrible AI picture, I didn’t create it I just found it on the internet and it was the only one I could find because these apparently don’t actually exist.
I’ve got a very similar panel myself, in fact it’s probably a bit bigger.
If you leave it out all day, under ideal conditions, it will put around 10AH worth of charge into a power bank, maybe a bit more, so 40-50 watt-hours if you’re lucky, over twelve hours.
Not a worthwhile amount of power.
That charges a phone just fine?
I use a smaller panel to charge a battery at a summer cottage. That keeps my and a few other people’s phones charged pretty alright.
Not worthwhile if you’re carrying it around all day.
Why? You can carry your phone and charge it at the same time.
