I have bought this product twice.
The first time it lasted 4 years and I was very satisfied. At first, I charged it with electricity. Later, the sun alone was enough.
I had it in a 20-square-meter caravan.
With one lamp it lit up all night, with three lamps it lasted well for 5 hours.
At some point it stopped working.
I bought the same model a second time, but unfortunately it broke down in three months. I don't know if it's because I didn't charge this second one with electricity at first, but put it directly in the sun.

Very good lighting with duration, minus one star for the solar panel which is either broken or needs days in strong sunlight to charge. For its price, it is satisfactory.

Carefully packaged, very good product. Very satisfactory lighting. Symptomatically, a two-hour power outage occurred a few days after the purchase, and with the device charged, we had light without candles, etc. The side lighting panel it has is very powerful. It also charges our mobile phones normally, with the indication on their screen "fast charging" (we did not do a full charge), as well as charging other devices that we tried. I recommend it because the price, in combination with its capabilities, is a worthwhile purchase. I bought it for 20 euros + 3 euros for shipping.
