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.

    Nah. You could DIY something like that for 30€ or something, let alone mass produce. The only problem is that the folding would be more clumsy and probably take a bit more space folded

    Edit: picture of a real product from which you could DIY one:

      I have 2, around 25cm x 30cm and, when perfectly aligned to a strong summer sun, they do 1 watt and 2 watts respektively. Amazing.

      Also, sitting outside in the harsh sun with a laptop? No thank you 😁.

      This is really niche stuff for when you can’t even reload your power bank once every couple of days IMO.

      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.

        Yeah this has always put me off solar panels like this, for their cost they make fuck all and if you just need power for a day or two it’s better to get a battery. Only if you need weeks does solar+battery start to make sense instead.

        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.

                Modern smartphones are terrible for energy consumption tbh, if you just want calls/SMS an old Nokia is so much more energy efficient.

                I suppose turning the phone off can help save, but how many people could even comprehend that these days?

      Slapping one together out of spare parts is not at all the same as mass producing one in a factory.

      And whatever you could slap together for 30 bucks would, as I said, in previous comment, suck and break very easily, not to mention that you wouldn’t be able to bring it anywhere close to the ocean for fear of everything corroding extremely quickly.

        Yeah. Mass producing can be orders of magnitude cheaper.

        It’s a ridiculous argument. Of course something like that could be manufactured, it’s just too niche of a market so nobody has made it a reality (yet).

      Lol that tiny ass solar setup ain’t charging both a laptop and a phone, least of all with them running.

      That can just barely charge a phone (source - I’ve done a lot of math around this, solar panels have very low output per square meter).

        I would think of using the solar panel to charge a battery pack instead, then you can power devices from that. Although you may be charging the battery for 8 hours to power a laptop for 2.

              There is a cable running from the solar panel to the laptop, implying the panel is charging the laptop.

              Which, based on my experience with them, ain’t happening.

                Oh in that picture. Yeah I didn’t even think about that, I’d imagine for the original use case you would charge a phone. Laptops need a lot of power, I didn’t even dream of charging one off of a portable solar panel lol :D
