laptop ac adapter HOT!!

Newer big screen laptops seem to tax their bricks to a greater extent. The little ASUS I acquired will go 5-hours on wireless. But there's not much to it. Near unbelievable how hungry the more powerful 17" are. I will check Vanessa's Toshiba when it's merely recharging the battery while shut off.

I don't believe this for a second !
20 yrs, 5-6 different laptops running on 4 different msw inverters.
All the bricks run warm (a little warmer than on grid) while charging the batteries after 3-4 hrs of portable use,
Never ever a problem on the incoming DC side of any of the laptops.

I would say your lucky! I have an Asus G73 and it was plugged into a MSW, got really hot (I didnt notice until it was too late). The laptop stopped charging after about 20 min of me using it. I checked the brick and I could have cooked an egg on it. It 'sorta' worked after it cooled off on regular power, but the Laptop's health program said the battery was not charging properly and the battery needed to be replaced. I used a different power brick and it charged properly.

I have seen a macbook fry after being plugged in for an hour to an MSW.

I had a heating pad fry in my truck and it was new, and plugged into a smaller MSW.

Maybe I have bad luck, maybe you have good luck.

I won't rely on luck anymore with my expensive electronics.

Watch one of the many YouTube videos of microwaves on MSW vs a microwave on a PSW. Without any electrical background, that should be enough!

Otter be a law forcing OEM to state battery capacity. And basic run watts with windows and then a spec given for the power brick. I might want to add I checked those computers when the temp was around 90F in the room. Wouldn't it be nice to have an external lithium battery with it's own charger and a 20 amp hour capacity? Dream On!

If there's one thing a laptop power brick doesn't care that much about, it's if the voltage is a little low or high. Practically all of them are universal/international models, and will work on any AC supply worldwide, from the 100V (nominal) used in Japan to 240V (nominal) in Europe, and 50 to 60 Hz.

Heat would more be related to the power being consumed by the laptop, which could be significantly higher when the battery is charging, the backlight is on bright, the CPU or hard drive is busy, etc.—especially if all are true at once. They do tend to run warm, some quite warm.

my 17" HP has a little bity power brick, smaller than the bricks for my external drives
it also has a skinny 8cell battery, good for less than two hours
my lenovo would go almost 5hrs when new and was still good for over two

48-63 Hz
88-254vac

I have checked three newer Laptops. Toshiba, HP, and Lenovo. All wwre less than a month old, all had full battery symbols and all three bricks were very warm. Vanessa told me her Toshiba tales forever to charge if she is multi tasking it. All three complained the batteries drain quickly when multi tasking. I have to believe my own fingers and ears. Who makes a 150 watt brick?

For clarification my toleran e to heat will not allow me to pick up a 50c power brick and clutch it tightly. All three machines have quad core.2.4 GHz processors or higher and 8 Gb of RAM. This shocked me. Thoughts of buying a 17" laptop went out the window. Useless for what I need

Not just running the machine. Good chance while camping the battery is also charging during use. At home it might be either-or vs camping is both.

Got gnus for some of you. Some 17" laptops eat juice like a wolf eats rabbits. Online, and with several cores going the brick stays very warm.
