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.
Comment on Solar powered personal umbrella with battery?

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.

Not worthwhile if you’re carrying it around all day.

Why? You can carry your phone and charge it at the same time.

Why do you need to charge your phone during the day anyway? Does it not last a full day?

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.
