The USB Wall Charger Surge Protector POWRUI 6-Outlet Extender Review
The USB Wall Charger Surge Protector POWRI 6-Outlet Extender is a good value, but it does have some limitations. The total wattage is capped at 175 watts per outlet, which is not very much, but it would be nice to have more flexibility. That said, this surge protection works great, and it comes with a strong guarantee.
Power absorbing ability of a surge protector
When used properly, a surge protector can protect your home from a range of risks. Its primary function is to divert excess voltage away from your electronic devices by directing it to the ground wire. Surge protectors often have a built-in battery backup to avoid losing power when a surge occurs. However, as with all electrical devices, surges will eventually deplete the surge protector's joule capacity, requiring you to replace it.
A surge protector will protect your electronics from voltage spikes in your home's AC circuits. Typically, these spikes only last one to thirty microseconds, but they can be dangerously high. They can exceed one thousand volts in just a few seconds. Lightning strikes can create spikes as high as 100,000 volts, destroying wire insulation and causing fires. Even a modest spike can destroy your electronic devices.
Safety features of a surge protector
A surge protector is a device that diverts excess voltage from your electric outlet into a grounding wire. It is an affordable way to protect your electronics, but it's also a form of insurance. Some models include warranties to cover these incidents. You should also read the product's warranty agreement carefully, as not all surge protectors are made equally. A surge protector can protect your electronics, but it can also damage some of your electrical equipment, too.
Another important safety feature of a surge protector is its ability to protect only those devices plugged directly into it. If you plug your computer and other devices into a surge protector that is too small, it can overload and fail to protect your electronics. Then, the surge protector can catch fire or fail to stop the boost of electricity, ruining them. You should also make sure that you buy one with a three-pronged plug, as these don't fit in two-pronged outlets and can short out your appliances.
Efficiency of a surge protector
The efficiency of a surge protector is dependent on several factors. Whether the surge protector is installed correctly or not is critical, as lightning strikes can cause power surges. While most surge protectors offer protection against surges that can damage sensitive electronics, they are not impenetrable. For this reason, a high-joule-rated surge protector is a better choice than one with a lower rating. If you have several devices that need protection from surges, a higher-joule-rated surge protector may be a better choice.
The clamping voltage tells you how well a surge protector can conduct electricity to the ground line. It is recommended that clamping voltages do not exceed 400 volts, as this is usually too high. Moreover, energy absorption and dissipation tell you how much energy a surge protector can absorb and dissipate. Higher ratings indicate better protection, but the amount of energy absorption is also an important consideration.
Price of a surge protector
A surge protector, or power strip, diverts excess power to ground, not affecting your electronics. It also protects your electronics during brownouts, but not from the longer-lasting effects of a surge. Uninterruptible power supplies, on the other hand, have built-in batteries that provide battery power to electronics when the primary power system fails. Priced at $1,300, these units are a great choice for a home or office with numerous electronics.
Most surge protectors are very expensive, but they are worth the price. These products are equipped with a 3-Level Surge Protection Circuit (SPC), which absorbs the excess power over a series of steps. The energy is suppressed until the circuit breaker trips, or the POWRUI's multi-plug outlet adapter detects a surge. This protection circuit can take up to 10,000 joules, so it's expensive but well worth the money.
