An extension cord solves this problem without relying on nearby outlets. Even if you own a desktop, you might need to put it where there isn't an outlet. You can do this safely by getting the right cord and using it properly. If you have to use an extension cord with your computer, make sure it's the right kind.

Keeping this in view, can you plug a laptop charger into an extension cord?

Is it safe to plug two things into an extension cord at the same time (specifically a laptop charger and phone charger)? Yes, provided that the extension cord has two appropriate sockets for the chargers. Most extension cords are rated at 3 Amps minimum and the chargers are likely to draw less than 0.5 Amps each.

Also to know, should I plug my computer into a surge protector?

If you want to protect your gaming PC and equipment from power fluctuations, you have to plug them in the right way. The short answer is no, power strips do not protect your PC from any sort of electrical fluctuations. However, you can get more sophisticated strips that have surge protection built in.

Can you use an extension cord with an extension cord?

Originally Answered: Can you plug an extension cord into an extension cord? Yes, you can plug an extension cord into an extension cord to make a longer one. But if your total length is longer, you need thicker wire for the same volts drop.

Can I plug my IMAC into an extension cord?

You should be fine, as long as you choose the proper rating and length of extension cord. Personally I would use a heave duty cord that is just a little longer than what is needed.


How many amps does a computer use?

Ratings of commonly used household appliances

Landline cordless telephone charger <0.5 10
Computer monitor <0.5 100
Desktop computer 3.0 700
Television 42" HD 0.5 120

Is it safe to plug a surge protector into an extension cord?

Can You Plug a Surge Protector Into an Extension Cord? On paper, yes, you can. The biggest thing is making sure the extension cord can handle the same amount of load as the surge protector (or more). Otherwise, you risk putting too much load on the extension cord and creating a fire hazard for yourself.

What is an extension on a computer?

A file extension (or simply "extension") is the suffix at the end of a filename that indicates what type of file it is. For example, in the filename "myreport. txt," the . TXT is the file extension. Sometimes long file extensions are used to more clearly identify the file type.

Can power fluctuation harm my computer?

The irregular power supply during the brownout can ruin your computer and other electronic devices. Electronics are created to operate at specific voltages, so any fluctuations in power (both up and down) can damage them. Those fluctuations can also harm your electronic devices.

How many outlets do you need for a PC?

Depends. I would recommend 8 or 10 outlets from a quality power bar or UPS backup power block. Two of the outlets should be high load outlets and all outlets should be well spaced apart from each other to accept bulky AC adapter plugs.

How much power can an extension cord handle?

For example, a 16 gauge extension cord less than 50 feet in length can power a 1625 watt (W) appliance. A 16 gauge cord that is longer than 50 feet in length can only power an appliance up to 1250W.

Are extension cords safe?

Using extension cords properly is critical to your safety. With continuous use over time, an extension cord can rapidly deteriorate, creating a potentially dangerous electric shock or fire hazard. Do not substitute extension cords for permanent wiring. Do not run through walls, doorways, ceilings or floors.

Do extension leads reduce power?

Long extension cords can cause significant drops in voltage to appliances. Anything that resists the flow of electricity causes voltage to drop. Whether an extension cord causes a noticeable or significant voltage drop depends on the length and gauge of the wire and the appliance plugged into it.

Are power strips safer than extension cords?

In fact, plugging multiple power strips together, which is known as “daisy-chaining,” is the quickest way to overload your electrical system—and it's also dangerous and violates most fire safety codes. For the same reason, avoid the use of extension cords with power strips.

Should a TV be plugged into a power strip?

Do you have your PC, television, or other expensive electronics plugged directly into a power outlet? You shouldn't. You should plug your gadgets into a surge protector, which isn't necessarily the same thing as a power strip.

How do you stop a power surge from your computer?

How Do I Prevent Power Surges?
  1. Inspect your wiring. Faulty or substandard wiring can make power surge problems worse.
  2. Unplug electronics during a storm.
  3. Use surge protectors.
  4. Install a whole-home surge processor.
  5. Install high-efficiency AC units.

What's the difference between a surge protector and a power strip?

The difference between a power strip and a surge protector is that a power strip adds extra outlet space while a surge protector defends against possible voltage spikes that could damage your electronics, appliances, or equipment.

What is the best surge protector?

The ultimate smart surge protector
  • Best all-purpose surge protector. Belkin 12-outlet PivotPlug (model BP112230-08) $31.99. on Amazon (Prime Eligible)
  • Best at powering-off when it can no longer provide protection. APC SurgeArrest Performance P12U2 surge protector. $39.99.
  • Runner-up. APC SurgeArrest (model P11VNT3) $39.99.

Can you use an extension cord permanently?

If you need to permanently connect an electrical device, you should use approved wires and/or cable assemblies installed in an approved manner. As Tester101 says, extension cords are not meant for permanent wiring.

Is it OK to daisy chain extension cords?

DON'T plug extensions cords together.
Get one that is the correct length you need. It may be tempting to just string them together, but resist the temptation. Extending the length of an extension cord by “daisy-chaining” can lead to overheating the cord by overloading it, creating a serious fire hazard.
