I used it for 10 days and it worked perfectly. Then it discharged and even though I charged it, the battery didn't last more than 10 minutes. Either I'm doing something wrong or it's defective. Since it discharged, I haven't been able to use it for my work and it doesn't serve its purpose (low lighting for newborns).

------------Update-----------
I finally found out what was wrong with it. It needs to be charged either with its own charger (which I had lost) or with an identical one. What I mean is: I was trying to charge it with my mobile phone charger, which has a USB-C on both ends, resulting in it not charging and behaving as I described above. When I tried to charge it with a charger that has a USB-C on one end and a classic USB on the other, it charged normally and the charging indicator light turned on (which didn't happen with the other charger). So, it charged and works perfectly without any issues. However, I deduct 1 star because it has a peculiar charging system and soon there will only be chargers like the one for my mobile phone, so it would be a problem if you lose its charger.

With the one charge I did in May, the battery still lasts, with 4-5 hours of use every night.
