I wouldn't see it as a problem....what are you concerned about?

 

Some devices are suggested to plug directly into an outlet, like scanner suggest that but it's just that it's an unusual thing to do I guess.

 

Well the only thing I would think would be because it might use a lot of amps.

If you used a heavier extension cord vs. One from like the dollar store it'd probably work just fine.

But this is just my opinion I've never had a reason to do so , so I can't speak from personal experience

 

Many people have their laptops plugged into a surge bar, and some use extension cords too. There's absolutely no issue with one being used with a laptop. Using cheap extension cords or surge bars with heavy draw equipment such as large laser printers can be an issue. Using a UPS or battery backup with laser printer is also not advised due to power draw and spikes caused by them turning on.

 

The only computer-related device that I've had that warns to plug it DIRECTLY into a wall outlet is a battery backup unit.
I've never had a problem with connecting a laptop to an extension cord first and then into a wall outlet.

Totally agree there is no electrical problem but do take care in the location of the extension cable because they can trip people up.

 

All good answers and everyone seems to be in agreement - thanks everyone
