Buying Guide

Before you buy an extension cord, consider the length of your cord and its amperage rating.

Numerous Outlets

Extension cords typically only have one outlet that can support a single device. An extension cord that supports multiple devices, such as the Anker Power Strip Surge Protector, can be used to plug them in.

Amperage Rating

An amperage rating is a rating that indicates how much power a power cord can handle. A higher rating means a stronger cord. While most extension cords can support 13 amps, some models such as the Southwire Outdoor Extension Cord are capable of supporting up to 15 amps.

Cord Length

You can have power cords as small as 6 feet or as long as 100ft. A cord less than 20 feet is sufficient if you are looking for an extension cord to charge indoor electronics. A cord 50 feet or more may be better if you are looking to power corded tools such as electric chainsaws.

Number of prongs

Most extension cords have three-prong outlets. However, some indoor models such as the GE Three-Outlet Power Strip can be used with two-prong outlets. A two-prong extension cable should be sufficient to charge a few devices. A three-prong extension cord is best for small appliances and tools such as electric drills. It tends to have an additional prong.

Most Frequently Asked Questions

What is the gauge of an extension cable?

An extension cord’s gauge refers to how large the conductors are. Extension cords with a smaller gauge of wire can carry large amounts electricity. 12-gauge cords, for example, can carry tool loads of between 10 and 15 amps. Outdoor extension cords are often of a smaller gauge to support heavy-duty machinery.

Can an extension cord be used to power my refrigerator

A heavy-duty extension cable can be used to power your refrigerator if it is not close enough to a wall outlet. An extension cord should have an amp rating that is equal to the refrigerator’s amperage. This will prevent fires.

What is a surge protector?

Surge protectors are devices found in many power strips. They protect devices from voltage spikes that can be caused by lightning strikes.
