It is problematic, do not buy it at first, it works well and then it shows that there is a constant connection on the phone. As soon as I switched to an old hama, the phone continued to charge normally.

The first time I used it, it took 5 hours to charge my phone, and the second time as well. The third time, it didn't work, it was broken. Disappointment

I bought 4 chargers. Unfortunately, I had my phone charging all night and in the morning the battery was only charged at 85%.

I recommend not buying this charger for the following reason. I have had it for 2 weeks and it was constantly plugged in, providing power to an indoor camera. Yesterday, there was a power outage for a short period of time and today I realized that the charger is not working. I changed the cable, changed the socket, but the charger simply stopped working.

Quite fast compared to a previous Lenovo that I had charged quickly and the battery stays, meaning it doesn't run out in a short period of time!
