Hey AgLA06,
Regarding this:
- Small foldable solar panels that power small electronic battery banks for phones / laptops
I was looking into something like this after Beryl, both for myself and my dad.
Do you have any recommendations as far as size, capacity, and brand names? Ideally, it would need to be very easy to use and light weight to move.
Thanks!
I'm not AgLA06, but hopefully you won't mind my reply anyway. For your purposes, a 256wh to 512wh would work, plus they are quite easy to use and are light enough in weight that a child could move one around. Add a 100w solar panel from Shadestopper and you will be able to power your small battery-powered devices almost indefinitely.
That being said, I would recommend going to a 1000wh unit, which would allow you to power things like fans, lamps, small refrigerators, etc.. If you go this route, you would want a larger solar panel such as the bi-facial 220w Ecoflow, among others. A 1kwh unit won't be light enough for a small child to easily move around, but they are still small enough to use/move/store by any older child and above.
As for brands, there are a huge number, but start your search with Ecoflow, Pecron, Bluetti, Goal Zero, Jackery, and Anker. I would also recommend that you stick with units that use LiFePo batteries because of their stability and large number of charge cycles. BTW - you can now buy units that use solid-state batteries, but they are extremely expensive.
The best prices for these types of products was when almost all of these companies had huge sales that coincided with Amazon's Prime Day. I believe that some have recently started these sales again since a Prime Day is coming up, but I can't tell you if today's prices are as good as they were over the summer. As for specific units: if you want something small, consider the 288wh Pecron E300 LFP. currently on sale for $159. For more of a "mid-sized" unit, consider the 512wh Ecoflow River 2 Max or the Pecron E500LFP that is also on sale at a great price (might the best buy in this size category at the moment). There are also a large number of other brands in this size category too, so definitely shop around for the best sales. For ~1kwh units, I like the Ecoflow Delta 2, but again there are a huge number of other brands to choose from.
Lastly, the reason why I mentioned the Shadestopper solar panel above is because their panels don't have a dramatic drop-off in power when covered by a little shade. I don't know how large they go however, so you will have to research how large a unit they can charge. Also know that different manufacturers use different connector types between panel and generator, but usually this can be overcome by merely buying the correct adapter plugs.
