    I have had it for a month and I have no complaints, it is very good, it charges our devices quickly and it also has the built-in cables that you can use if you don't have your own cables with you. It charges itself quickly with a cable but slowly with solar power because it is for emergencies, not for play. Overall, I am very satisfied and its size is not a big disadvantage, it doesn't inconvenience me anywhere

    I have had it for 1.5 years. I used to charge it with electricity and overall I was very satisfied with its durability. A week ago, I left it to charge with solar power for the first time and it broke...... The plastic in front, which shows the battery level, came off and got distorted. Since then, it needs to be charged with electricity, of course, for 2 full days and it takes 2 days to charge the phone. If you want it for solar charging, do not buy it....!!!!!!!!

    Far away. After the first charge, it doesn't go above 50% no matter what.
    Also, it's not portable. It's not suitable for trips, etc. In Scrooge's photo it doesn't show, but don't think it's thin like a mobile phone. On the contrary, it's as thick as a brick and very, very heavy.

    While it is well-made and has all the charging ports, it does not take solar energy. I tried for many hours while camping, but nothing.

    I bought it a year ago and it was the worst. First of all, the solar panel didn't work and the charging was very slow. It also ran out quickly. It would charge once and only reach halfway. I believe it was defective. If someone can send me an answer on how it works
