Choosing the best metal surge protector will often depend on what devices you need to plug into it. Some of the defining characteristics of surge protectors include amperage and voltage ratings, plug configurations, and the monetary value of the warranty that is included. If you have a lot of equipment to plug in to one surge protector, you may need to find one that can handle a large load. The type of plugs your equipment has may also affect your decision, since some surge protectors may not readily accept certain plug types. Some surge protectors also include phone or cable jacks, if you require that type of protection.
In order to determine which metal surge protector is best suited to your needs, it may help to list the different devices you would like to use it with. This can assist in determining how many plugs it will need, the power rating, and the best plug configuration. If you need a metal surge protector for your computer and related equipment like a modem, router, or external hard drive (HDD), that may affect your choice. A phone jack feature may be useful if you have digital subscriber line (DSL) Internet, or if you have cable Internet, a unit with a coaxial connector may be a good choice.
Some devices use bulky transformers that are integrated into the plug, which can make it difficult to use with certain surge protectors. Unless you choose a metal surge protector with adequate spacing, you may find that one plug can cover up two other sockets, reducing the overall capacity of the power strip. If you need to plug in devices with large adapters, it may be a good idea to find a surge protector that has wide enough spacing to allow use of all the sockets.
One of the most important things to consider when purchasing a metal surge protector is the warranty offered by the manufacturer. Many surge protectors offer some level of warranty that will be clearly indicated on the packaging. If the surge protector fails and your equipment is damaged, these warranties can help you replace expensive devices like computers, televisions, and other delicate electronics. Choosing a surge protector that has a warranty worth more than the total value of the equipment you will plug into it may ensure that you do not have to pay for costly repairs or replacements out of your own pocket.
