While its level of protection isn't disclosed, it does come with overload and short-circuiting protection, and the whole thing is made of premium flame-resistant materials that are RoHS-certified. Computers, laptops, printers and other office devices and electronics are welcome, but it's safe for home use as well, especially with its built-in safety outlet cover to protect kids and pets. A surge-protection rating of 400 volts or better: Although we verified each model’s abilities in our own electrical testing, we required that they be rated by one of the major product-safety corporations, UL or ETL, to bring a surge down to (at most) 400 volts. Lower is better when it comes to let-through voltage, the measure of how much extra voltage reaches your electronics.

While this ExtraStar lead surge protector doesn't say exactly how much protection it offers, this is a great option for budgeting households that doesn't have very demanding plugging needs. This is a cheap yet realiable extension cord perfect for smaller bedrooms and kitchen, especially with that 3.3ft cord - it just means you don't have a lot of cord length to put away when you're working with a tighter space.

Don’t plug a space heater into a surge protector. Space heaters and other appliances with an open heating element (such as toasters or hair dryers) use a lot of power, increasing your chances of overloading the outlet. A surge protector adds even more resistance that can allow heat to build up, potentially catching fire or damaging the device. To be on the safe side, plug any open-heat electronics straight into the wall.

With 12 outlets and two USB charge ports, it matches the APC Performance SurgeArrest 12. It has a lower energy rating at 3,996 Joules but is still more than enough for most. It’s also available in white. It does have eight AC outlets, two on each side, and each pair has its on/off button to help save energy and help you save money on your energy bill. Plus there are three USB Type-A and one USB-C ports. The only thing is that those ports are only on one side so anyone needing access to them would have to do some sort of maneuvering, especially if there are several electronics and devices already plugged in.Finally, some surge protectors are equipped with fail-to-safe conditions, also known as automatic shutdown technology and "fail to shutdown". When the surge protector experiences a surge and the arrestors reach their end of life, the device stops sending power to your devices, telling you in no uncertain terms that it's time to replace it. There are eight outlets included, two on each side, plus three USB ports on top right below the power button. You do have the choice of either three USB Type-A or two USB Type-A and one USB-C port, which is nice, and it has four non-slip feet for a secure base. Plus you can choose the length of cable: two, three, five and 10 meters.

As for your charging needs, there are 12 AC outlets on hand, with enough space between each outlet to accommodate all your devices, as well as two USB Type-A ports and one USB-C with power delivers for fast charging - allowing you to fully-charge your iPhone in an hour. Just bear in mind that the USB and USB-C port do share output so if you're using all three at once, it will slow down all three to just 15W. When you first plug in a surge protector, make sure the status lights don’t report any problems. Most protectors have a single grounding light that indicates whether there’s a ground fault. If there is a fault, call an electrician as soon as possible to determine whether you have a wiring problem. A ground fault could fry your devices, electrocute someone, or start a fire. It is a little basic in terms of its line of protection, but you are getting three layers here - just enough to protect your kitchen appliances and small electronics at home. And its six foot cord means that it's a little more versatile in its location. We wouldn't recommend using this to regularly power your PC or laptop, however, as it won't offer enough protection if a surge does happen. As for the ports, there's a lot of them. 12 AC outlets and six USB Type-A ports mean that you'll never run out of a place to plug in again. There's just no USB-C port, unfortunately, but that can be easily remedied. Never use an adapter to plug a surge protector into an ungrounded outlet. Bypassing the ground negates most of the benefits of using surge protectors, since typically two-thirds of their MOVs are tied to the ground leg.

And note, not all power strips offer surge protection. Some act as nothing more than an extension of an existing wall outlet. Some might add a layer of minimal surge protection. So, regardless of shape or size, all units on this list will give strong levels of protection.

Still, it sits cleanly on a wall and can work well next to a nightstand to plug in a lamp and some phone chargers. For travel and small spaces, the 3-Outlet Mini Surge Protector with USB ports can come in handy. Just use it mostly for smaller devices. What's unique about this surge protector is that each of its AC outlet - it has four - has its own switch, which should make a difference when your next energy bill comes around. To ensure the kids' safety, each also has a safety door. And though it doesn't specify its protection level, it does offer overvoltage, overcurrent. and short-circuiting protection. It is best to buy a surge protector from a reputable brand, not a no-name company. A well-known company not only stands behind the quality of its electronics but also provides a warranty covering the devices they connect. An electrical surge is a brief spike in voltage. They can be generated outside your premises or within it, depending on what equipment is malfunctioning (mainly electric motors, such as water pumps, building elevators, etc.). These surges can cause damage to electronic equipment within your home or office. The Monoprice 12 also has lights that indicate if surge protection is working, and if protection fails following a major surge, the light will shut off. The device will auto-shut to prevent damage to electronics. It’s also UL Listed.To put the Joule rating of a surge protector in simple words, it indicates how much energy a device can absorb before the filter stops functioning. So the higher the joules, the more filtering it can do, and for a longer time, as each spike that hits your surge protector weakens its filtering ability.
