Whether you just want to add more sockets or create an extra layer of protection between your equipment and the outside world, you'll want to buy surge protectors.
With an incredible price range and features, not to mention a flood of questionable marketing promise, it's hard to figure out what's worth the money and what's nonsense. I'll help you with the search.
Take a look for a small background. This article is the updated successor of this article, although we will cover similar topics.
. 1 Surge protection against multiple sockets
Multiple sockets and overvoltage protection, also called overvoltage protection, differ from each other.
Power strips are usually cheap products with multiple sockets, which are merely an extension of a wall outlet. These usually have a circuit breaker (on / off switch), but most do not offer any real protection against electrical problems. Some may offer the least protection, but they are all similar to being plugged directly into the wall.
Surge protectors are also relatively cheap, but offer some protection against voltage surges unlike power strips. How much and how much varies.
. 2 Around the Joule.
Surge protection provides protection in amounts called joules. In general, the more joules, the better, as the unit can handle one or more minor surges before your equipment is in danger. Over time, the parts inside the protector wear off and reduce its effectiveness.
There's no way to tell how much protection a device still has, or if the initial rating is still accurate. The wirecutter has conducted a massive test on surge protectors, essentially testing how well they worked and whether they could answer that question. See also # 10.
3. A guarantee … on your belongings.
Some surge protectors provide a guarantee (up to a certain amount) on the devices connected to the protection device. For example, in the United States, a Belkin model is covered by a $ 300,000 device warranty: "If your electronic devices are damaged by voltage spikes, surges, or lightning strikes when properly connected to this power strip, we will repair or replace them until: to $ 300,000. "
You probably will never need it, but it certainly does not hurt to have it. Remember, only because the warranty is in place, you will never see a penny of it.
. 4 You probably do not need a power conditioner.
There are a number of products on the market that claim to "condition" the performance from the wall, which promises improved performance of your equipment.
Here's the dirty little secret: your gear will do that. All electronic devices have a power supply that picks up the incoming wall power (120V in the US), filters it for noise, and converts it to the power required by the device. Almost nothing is actually powered by 120 volts (or AC). So if you do not have really crazy (or cheap) equipment and live in an area with bizarre inadequate performance, a power conditioner is not for you.
. 5 Get more and more outlets than you need.
You will need more and more power outlets. You will undoubtedly add more equipment without necessarily getting rid of your current equipment. I'm not saying that if you think you need 4 outlets, get a 12, but a 6 is probably a good investment.
. 6 Get one with enough clearance for big plugs.
Many appliances use wall warts – plugs that convert AC to DC and look like small boxes with protruding electric prongs. Consider overvoltage protection with a greater distance between jacks or jacks that can be rotated or moved to accommodate bulky plugs.
. 7 Power surges can also lead to telephone or cable lines.
If you want full protection, keep in mind that telephone and cable lines can cause power surges. Some surge protectors also have connections.
. 8 USB is great, but check the amplifiers.
Many surge protectors are equipped with USB ports so you can charge your mobile devices without using their wall warts. Handy, but check the output power. Generally these are either 1 or 2 amps (often labeled 1A or 2A). So much flow you can get through the pipe, so to speak. For faster charging, you need at least 2 amps.
We currently have no recommendations for certain surge protectors, but you can find a variety of options on Amazon for as little as $ 20 or less.
