Will using 3rd party USB-C charging brick affect Apple Watch Series 7 battery capacity?

I recently purchased a new Apple Watch Series 7: I have been using a cheap 3rd party USB-C charging brick for the past two weeks with the charging cable included with my apple watch, I want to know if using a cheap 3rd party will affect my apple watch's battery health or not. So far I have not seen any problems or impact on battery capacity (still at 100%).
