Published a performance and safety test of an #IKEA charger at the (former) #twitter - to test how warm it would get, I let it run a full power for an hour.
It gets warm, but not alarmingly so
Electronic Loads are paramount when you’re testing or building power supplies - initially as a young designer I didn’t think much of it, but I’ve really come to like them and I’m happy to have one at the bench (and at work, btw)
