The selection of a good voltage protector for your laptop is important. Overvoltage protectors take electrical charges that can damage your equipment and ground the shake, which allows your laptop to continue without being damaged. Comparing several different surge protectors is a good way to make sure you are getting the best quality for your money. Electric current peaks are caused by external forces such as lightning or by internal forces such as changing the air conditioner on and off.
1. Check any power strip you consider to make sure they offer surge protection. Many socket boxes look like surge protectors, but they only offer an electrical extension, not protection against voltage spikes.
2. Compare the price of surge protectors. Surge protectors that offer more protection for your laptop are likely to be more expensive.
3. Choose a smaller surge protector. Although large surge protectors can be a bit cheaper, they are too difficult to handle to carry with you. Since your laptop is a portable device, you want to have it protected at home and away from home. Portable surge protectors are available to help you protect your laptop when you’re not at home.
4. Compare the power values. You want something that has a fixing voltage between 330 and 400 volts – this is the level of power that must be reached by electricity to be grounded. You also want a surge protector with at least 200 joules of energy absorption and dissipation. This number indicates the amount of energy the protector can handle before it fails. The higher, the better – for the best protection, try to get something that can handle 600 joules
5. Compare the guarantees offered by the manufacturers. In some cases, you can get full compensation for a laptop that has been damaged when it was connected to a surge protector. Having a full warranty available will help put your mind at ease, since, if the surge protector fails, you do not have to be without a computer.
