Is there a surge protector built into my A/C adapter for my laptop charger?

Question

Just wondering. And if not, is it that big of a deal if I don't use a surge protector?

Answer 1

Its doubtful your adapter has one built in.

You dont have to have one....but if you cant replace your laptop if something happens to it you might want to invest in one just to be safe.

Answer 2

All modern A/C adapter on laptops have built in power regulators.

Laptops are designed for travelling worldwide so it can handle worldwide voltages. Normally, it should be able to handle anywhere from as low as 90VAC to 250VAC. Some adapters have built in thermal sensors which monitor the temperature and shuts down the adapter to prevent it from overheating.

So the answer is yes. There is a limited surge protection capability on your A/C adapter. However, Surge protection only works if the power outlet is properly grounded. If not, you will run the risk of damaging the A/C adapter since surge protection does not work without proper grounding.

I'm on my 9th laptop in my 11 years of working. The only problem I had with the A/C adapter is a cracked plastic housing which cracked when the adapter got too hot. Even with a innards showing, the A/C adapter still worked flawlessly until I returned it to the manufacturer who promptly replaced it without question. I had co-worker who fried his A/C adapter because the power outlet he used didnt have a ground wire.

Answer 3

No its just a power converter. you can and should get a surge suppressor. If you travel alot with it you would want to consider a laptop surge supressor.

Answer 4

No, it's not that big of a deal. At least if you have a big lightening storm and your computer breaks, you'll know what happened.
