I recommend the charger. Different pros: Charges each battery separately. In conventional chargers, they are charged in pairs. And in toys, as a rule, 3 pieces are used. Therefore, you have to charge batteries with different charges, which simply kills them. That's why I use this device. Different cons: He does not see batteries with a small charge. (writes missing battery). You have to push them a little. I connect a charged and a discharged battery in parallel for 30 seconds. The discharged one is charging and then he sees it. It would be nice if there was a button on each forced charge battery to push the batteries. If I'm not mistaken there are 3 levels of charge current. Before charging, I look at the charge current on the battery. Haven't hit the right spot yet. It would be better if the manufacturer added a few more current levels.
