MagSafe isn’t the same as Qi2. It’s similar (very similar), but not the same.
Qi2 is (very short explanation) the newer, better version wireless charging (that Apple helped to develop).
If you live entirely within the Apple device ecosystem, MagSafe and Qi2 basically have the same functionality. But if you go outside the Apple device ecosystem, Qi2 is what you want (over MagSafe).
I’m not arguing that technology differences means it’s worth paying significantly more in price. But there (likely) is a difference between your “no brand” charger and these two Qi2 chargers.
(I say “likely” because I don’t know what “no brand” charger you own. Probably it isn’t Qi2, but I don’t know that for sure.)
