Not at all, the chargers are very cool and never get warm. Not sure what it is called in English but in Swedish it is called "jordfelsbrytare", its a system that have replaced the ground/earth cable here in modern Swedish homes. Its an even better solution den earth cable. So i feel very safe with the solution :)
It really makes me laugh that you creators seem to think that us lesser beings have all these tools to be precision perfect. Who has a pillar drill for instance as I certainly don't nor have room for.
The thing is, it costs less than most other tools I have so if you have space for a 30x30cm wide tool on a bench then a drill press is a given thing to get. No need for a huge version that stands on the floor. Thanks for watching! 🙏
