Reliable, convenient, with a flashlight and a battery that charges a phone and tablet twice (therefore it covers at least two days of use for both devices) and in case it cannot be charged, it also has solar charging. Obviously, this is a desperate solution but nonetheless, it is a solution. The only downside is the increased weight.

If with a palm-sized solar panel we could charge a 20,000 mAh power bank in 5 or 10 hours of sunlight, we wouldn't have to pay for gasoline and diesel for our transportation. Cars would have a panel on the roof and travel with the sun... Solar charging with such a small panel is only for emergency situations. So, it's not the machine's fault that it doesn't charge quickly with the sun.

The major problem is that (1) it charges very slowly in the sun (much slower than it discharges), and (2) it does not seem to charge from the sun when devices are connected to it.
I bought it, among other things, to connect a Pi Zero W outdoors, and it doesn't work.

It's worth its money! It's of good quality, the battery doesn't inflate after a while like other branded ones............ It charges and recharges quickly....... The light is quite powerful...... I would buy it again
