Recent Posts

The argument of power strip vs. surge protector is a common one as both devices can are often found in the home. There’s a lot of similarities on the surface, they both look similar; but they serve very different functions. Knowing the differences between them helps understand what you need, and can have drastically different impacts on electrical safety.

What Does a Power Strip Do?

A power strip is basically a casing with a bunch of outlets built into it. There is a cable on one side that you plug into a wall outlet. Plugs from different devices are inserted into the power strip’s outlets.

While a power strip may have an on/off switch and a small circuit breaker, it offers very little protection. The unit works pretty much like an extension cord. The risks of relying on a power strip include:

  • It can be overloaded by exceeding its rated wattage, which is usually the same as the wall outlet.
  • Plugging in too many devices can overheat the strip, leading to potential electrical failures and fires.
  • High-power devices, such as floor heaters, should never be plugged into a power strip.

Why Use a Power Strip?

It is a convenient and cheap way to connect more electrical devices at home, in an office or store, or at a construction site. Turning the strip on and off disconnects all devices plugged into it at once.

What Does a Surge Protector Do?

Although it usually looks much like a power strip, a surge protector offers more functionality. It plugs into the wall outlet and has electrical sockets. But there are sophisticated built-in electronics designed to prevent power surges.

A surge protector works by redirecting spikes of electricity into the ground. Excess current does not reach the electrical device, so it is not damaged. Such an event can occur when:

  • You turn on a large appliance, like a fridge or washing machine.
  • A nearby electrical transformer is damaged or malfunctions.
  • There is a lightning strike in the area.

Since home electrical devices rely on a constant flow of current, this can be very damaging. Even small surges can cause issues over time (and they happen quite frequently).

How Do I Tell the Difference?

  • A surge protector costs more than a typical power strip.
  • It also lists a joule rating; that’s the maximum amount it can handle before it must be replaced (whether cumulatively or all at once).
  • Power strips are usually under $20; surge protectors are usually a little more expensive.
  • A surge protector usually says “protection” or “suppression” on it or the product label.

How Do I Choose a Surge Protector?

  • Select a joule rating carefully; the larger the devices you connect and the more power they use, the higher the number should be.
  • Invest in more outlets than you need; a couple of extra outlets can come in handy when you decide to add more gear.
  • Purchase a surge protector with more space between some sockets, for larger plug boxes, in addition to standard spaced plug sockets.
  • Get one with connectors for phone and cable lines; surges can come from there as well.
  • If you get a surge protector with USB connections, check the amp rating for each; 2 amps allows for faster charging.
  • Look for warranty protection; it may cover damage to connected devices by transient voltage surges while using the surge protector.
