The charger provokes frequent replacement of batteries, sometimes relatively new ones, thereby harming the environment and your wallet.
Pros
Sometimes it charges if you're lucky. There are various smart features. There is also a screen and even a few buttons. The device claims to be smart.
Cons
I wrote down half of the batteries (about 10 pcs. ) as faulty, "null" is displayed. In this case, "faulty" batteries are normally charged on a conventional charger.
