Having experience with a similar but noname charger that was 10+ years old, on 14/6/22 I bought 2 chargers from a store on the skroutz list. One was missing the plug for temperature and the other was just a plug without a sensor. They are "fake" mainly in terms of weight, coolers, and the menu that lacks indications even though the manual mentions them, with the main lack being the indication of the charging Amps, consumption, and history.
There is a setting for the maximum charging voltage and while I had it at 13.8, as long as I was consuming electricity, the chargers seemed to work fine. However, after a day when I was away and not consuming electricity, the battery voltage reached 15.6v and the batteries were boiling, with the temperature showing "- -" on the charger's screen and everything burning! If I had been away for a little longer, I would have found only the ashes of my house.
One star.

One of them burned a few days later with an impressive explosion, also dangerous. I was afraid of the other one and gradually increased it from 13.8 to 14.4 and eventually it also exploded.
Now in my opinion, if you keep it away from flammable materials and for light work, it's fine and economical. During periods of even low cloudiness, it cannot charge. If you want daily charging "regardless of the weather," generally PWM chargers don't do it and we have to go for MPPT chargers, which are considerably more expensive.
