I bought it because we were going camping, so I thought the solar charging might come in handy and the power bank has a large capacity of 4–5 charges for my phone. However, after reading the manual, you find out that you cannot expose the battery to sunlight for a long time, otherwise it may overheat and get damaged, and at the same time, if it is not in direct sunlight, the charging performance of the solar panel is not optimal, so the manual pretty much forbids using the solar charging. We have it placed on the windowsill in the hallway and if it charges by one extra LED (out of 4) in the summer, I'm glad, but usually it doesn't charge much. The solar panel should at least be strong enough to keep an unused phone alive, so maybe for some long-term camping without electricity. The charger is very large and at the same time very slow, so my phone takes easily an hour to charge, meaning it's neither for a quick charge in a backpack nor for easy carrying in the hand while charging a phone. At the same time, the charging is so slow that I wouldn't even dare try it on anything larger. I haven't really used the light much. I wouldn't buy it again, it's not very practical for everyday travel, e.g. by train.

Solar charging only works as a backup, it barely charges
Very slow charging, it more or less just keeps the phone alive

I had this power bank in hand along with a very similar Viking W24W 24000mAh so I could compare them side-by-side. How Spello 24.000mAh is better * Weighs about 10% less. * All inputs and outputs are under one cover, so you don't have to wonder which one to open. * It has a more powerful flashlight. * It looks better (at least in my opinion). How the Viking W24W 24000mAh is better * It has a more powerful maximum charging standard - 9V,2A,18W (vs. 5V,3A,15W for Spello), so if your charger supports it, it charges faster. * It has higher certified water resistance - IP67 (compared to IP65 for Spello). I haven't tested. * The grooves on the side make it hold a little better in the hand. * The solar panel charging indicator is right in the panel, which I find more intuitive than with Spello, where it is on the side. I would also like to add that both power banks suffer from a minor annoyance that the diode charge status indicator does not move evenly when charging and discharging - the upper diodes have a higher endurance than the lower ones, which distorts the state of charge. With the Spello 24,000mAh, however, it's a bit more noticeable (I measured it on a stopwatch).

In short - it's big, but it holds a lot of juice and the lamp is really powerful.
The capacity is really impressive.
The interior lamp is no firefly, it illuminates the space almost like a car headlight.
It's a brick, it's not pocketable, and it'll go in a backpack. But it's the price of being able to charge something for a really long time.
The solar panel is more of a cosmetic accessory, the main charging must always go through the mains charger.
