laptop ac adapter HOT!!

Is it running off an inverter?

This happens at electrified sites at campgrounds.

DH says yes.

Almost all laptop AC power supplies (from the simplest wall wart to the biggest brick) contain a transformer, which heats up during use.

Proper design would suggest that some form of heat discharge needs to be built into the case, but most of them are built on the cheapo.

So, it doesn't matter what campground you're at; as long as it's plugged into a shore power 120 VAC outlet, it'll get hot!

It's only dangerous if the adapter is sitting on something extremely flammable -- like your lap! Most countertops, furniture, etc. should be OK, but check them periodically, just to be safe.

Thanks a lot!

Get a Google Chromebook by Samsung, problem solved, and a lot less heat and watts made /consumed.

I suspect you are using a MODIFIED SINE WAVE INVERTER to give you 120VAC to run your laptop computer charging brick. This will eventually burn up your transformer brick... Transformers really like to have PURE SINE WAVES...

The only other way to overheat the laptop transformer brick is to PULL TO MUCH CURRENT trying to charge your LAPTOP. PERHAPS the LAPTOP BATTERY is going bad on you... Just be sure you are using the correct transformer brick for your LAPTOP.

My DELL LAPTOP bricks get warm running on good 120VAC Shore Power but never HOT... When you are saying HOT I am thinking too hot to touch????

X2, If there are electron flowing there is heat being generated as in tranformers, or any wire that is in use. JMO

Thanks, am learning a lot here.

Hotter than at home ?
It's plugged into an out let that is connected to campground power
Or
Is connected to an inverter
