If you own a PC or equipment such as a high end speaker setup or a high end home theater system, you probably need an extension cord to connect all of it, right? Well, what we would usually do is go to the nearest hardware store, get the cheapest extension cable we can find that has the right amount of outlets and then proceed to connect everything to it.
While this may seem to suit all your needs, unknown to you, you’re actually putting your components at risk. Let’s break it down. Extension cords that are sold in ye average hardware store are useful for connecting simple devices such as lamps, radios and even phone chargers. They have no built in mechanism to protect against voltage surges or overloading of components.
This is where a Surge protector comes to the rescue. Unlike a UPS (Uninterruptible power supply), a surge protector will protect all components connected to it from any power fluctuations and electrical surges. If an excess current flows through, it will be dissipated through the Earth grounding.
A Surge protector is not exactly cheap and costs around the same price as a UPS and most people seem to think that a UPS will also have a built-in surge protector. Well, they do, it’s just not cheap.
We got our hands on a Fujitsu SP421 Surge Protector. Interestingly, this device has been on the market for quite a while. The reason that no one seems to want to buy it is that it looks to be an overpriced, glorified extension cord. Priced at LKR 5,000/- we found out that it’s a lot more.
Honestly, we were not too concerned about the packaging. That being said though, the packaging was quite impressive. The Fujitsu SP421 comes in a matte black box with an image of the device on the left along with its features listed on the right. The back of the box lists down all the specifications of the Surge protector along with a few more details such as batch number, in a number of languages. Once you open the package, all you have to do is to take the Fujitsu SP421 out and start using it.
At first glance, there’s no doubt about it, the device does look like a very fancy extension cord. Sporting a 2M thick cable, the Fujitsu SP421 is made of a durable, sturdy plastic shell. It has a matte black color scheme with a red stripe going around it to add a bit of class to it. The top of the power strip has the Fujitsu logo printed and right below that is a power switch. Right below that you will find two indicators that say whether the power strip is grounded or protected.
You will also find 4 13AMP plug bases. The build of the base itself is actually very well thought of. Each socket has an automatic shutter that prevents foreign objects being inserted into the socket. This lessens the probability of accidental electrocution and is also helpful if you have children who like to poke stuff.
At the bottom of the Fujitsu SP421, you will find 3 USB ports. These are used to charge your devices. Interestingly, one of them is a Qualcomm Quick Charge 3.0 port. This means that you can pretty much get really fast charging for devices that are Quick Charge 3.0 certified.
The sockets on the Fujitsu SP421 are rated at a Current of 13A and can withhold a maximum load of 3,250Watts. For the record, that’s almost 4 High-end gaming rigs connected to one Fujitsu SP421 Powerstrip. In case of a rogue power surge or lightning strike, the Fujitsu SP421 is theoretically capable of withstanding a voltage spike of almost 6,000 volts. That’s pretty much enough to leave a nasty burn on your skin or even completely destroy any appendage that comes into contact with the current phase. It can also essentially stop your heartbeat.
The Fujitsu SP421 operates at a regular 250V~50-60Hz voltage and has a less than one nanosecond response time. This means that the moment a power anomaly is detected, the circuitry behind the power strip would jump into place.
Using the Powerstrip is fairly straightforward. It literally takes plug and play to a new level. Simply plug in the 13AMP plug into your nearest 13AMP socket and you’re good to go. The indicators on the Powerstrip will light up according to the incoming power. For example, if the power line is not grounded, the “Not Grounded” notification will light up. once you switch on the Powerstrip, another indicator shows that the power strip is indeed getting power.
Connecting devices to the Fujitsu SP421 is also quite easy. All you do is connect a device to any of the socket on the Powerstrip and you’re good to go. Because of the child lock, you rest assured that the Powerstrip is extremely safe to use.
For our tests, we connected four high end PCs with 600W PSUs to the Powerstrip and proceeded to game on it for around 2-3 hours and we actually managed to not blow a fuse (literally and figuratively). With that out of the way, we proceeded to test out the USB ports on the Fujitsu SP421. For the record, I connected my friend Kaushalya’s OnePlus 5 and was able to go from 5% to 65% in a little under 15 minutes. That is actually pretty fast. Plus, we didn’t have to worry about leaving chargers behind.
Apart from that, we also tried a Samsung Galaxy S8 and an iPhone as well. While the OnePlus 5 and Samsung device made use of Qualcomm’s quick charge, even the iPhone was quick to charge. The Fujitsu SP421 incorporates 2 30W, Adaptive USB Charging ports. As such, you will find one Quick Charge 3.0 Port that is capable of delivering 5V/3A, 9V/2A, or 12V/1.5A. The smart port, though not Quick Charge 3.0 certified can deliver a max current of 5V/2.4A.
Well, basically, everyone can use it. If you own a bunch of high-end equipment we recommend getting one of these power strips. If you have a high-end PC and you also suffer from voltage fluctuations, then the Fujitsu SP421 can be put to use as well. Now bear in mind that is not a UPS. It will not provide additional battery backup. But rather, in the event of a freak lightning storm or powerful voltage surge, the Fujitsu SP421 will absorb the spike, and act as a protector, keeping your components safe.
If you’re looking for a device such as this, give the Fujitsu SP421 a go. Want something with more ports? Check out the big brother of the Fujitsu SP421, the SP621 that has 6 13A sockets, one Qualcomm Quickcharge 3.0 port, and 3 adaptive charging ports.
If you already have one of these, do leave a comment on what you think about it.
