Review on Adapter Charger Replace IdeaPad Chromebook by Jason Elliss

This adapter works great with my Lenovo Flex5 14IL. However, there is one major annoyance and potential security issue. The square adapter block gets very hot every time I use it and makes a rumble, a lot of noise, like it has a swarm of hornets and buzzes angrily. . These are the main reasons for concern! Otherwise, the power supply is very useful as a backup, as long as it works properly and does not cause security problems. I rarely use it as a backup, but the thought of something sparking in it is a constant concern. me and since it gets so hot I feel like it could just catch fire and pose a safety hazard. Has anyone else encountered such a problem? Can the seller/manufacturer comment on this issue?
