Surge Protector and Laptop

Jul 31, 2019 12:10PM PDT

I just bought a power bar with multiple outlets which has surge protection. I am thinking of plugging in my Acer Aspire V 17 nitro laptop into it. However, I recently read that I should mix up "extension cords" with surge protectors. On my laptop the power cord goes from the computer into a rectangular "box", and then I plug in the power cord from the wall outlet into this rectangular "box". Does this count as an extension cord, which means I can't plug it into my surge protector safely? Also, out of curiosity, what about chargers for my Android tablet? I plugged the cord into the USB port on the charger then plugged that into the surge protector. Now, I am using the USB charger port on my surge protector.

Some truth in that.

If the power bars or suppressors have a wiring error you could get into trouble. There are simple under 10 buck outlet checkers which I'll share a link to without endorsement.

The tester would be used on all outlets and one more thing. DO NOT MIX across the room in the USA as another wiring defect could get you 240AC vs 120 Volts. This is extremely rare so there are at least two wiring defects that could cause trouble and why this advice was given.

As to the USB charger, a good charger would not care as well as the device under charge.

What exactly do you mean with "mix up" and where did you read it (it would be nice if you have a link).

I wouldn't call a power adapter for a laptop call an extension cord. It changes 120V AC into 19V DC. For most devices (like a TV or a desktop PC) the equivalent is built in.

Same for the phone chargers, althoug they change the 120V AC into 5V DC and are smaller.

Go to your local hardware store and buy a socket tester like R.P. showed.

Around 10 bucks.

Plug it into every socket on the power bar.

If the lights show good then it should be safe to use.

Now go to every socket in your home and use the tester.
