Hi everyone, Dave here. Today I'm testing a UPS or uninterruptible power supply that contains a lithium iron phosphate battery
0:07
After years of replacing lead acid batteries in my uninterruptible power supplies or UPSs every year
0:12
I kept wondering why Lifepo4 batteries are not more common in UPS applications
0:17
Please note I do not accept commissions for product reviews and Golden Mate provided this UPS for testing
0:22
This UPS has a pure sine wave inverter and 800 watt output and it weighs about 12 pounds
0:26
The Luthermiron phosphate, or L-I-F-E-O-4 battery pack, is 8 cells in series, and it's about 24 volts, has a bit over 200 watt hours of storage
0:35
In theory, it's enough to get your computer hibernated or shut down cleanly and safely if there's a power issue
0:41
If you have a laptop or very small computer, perhaps you could continue operating for an hour or two from the battery power
0:46
A UPS is supposed to sit in between computer equipment and AC mains power and quickly step in to supply backup power when there's a surge or power interruption
0:54
It provides temporary mains power so you can keep working or shut down properly
0:59
A UPS can protect sensitive computers and equipment and save your computer from resetting and losing what you are working on at the moment of a power interruption
1:06
The most obvious question I have is does it work? Let get right to the point I going to plug in two computers and a Wi router Let the UPS charge up then I will yank the cord and see what happens Either it works or it doesn A UPS must have
1:20
very fast reaction times or it just doesn't work properly. Computers in particular and related
1:25
equipment are sensitive to power brownouts and interruptions. If anything goes wrong, they tend to switch off or crash
1:33
Let's take a look at the product page for the UPS. It's rated at 1,000 VA or 800 watts. I wouldn't
1:39
really want to put 800 watts through this thing. Running a desktop computer and a Wi-Fi
1:44
router for a few minutes really shouldn't require 800 watts, but it's nice to know that the
1:48
maximum capability is 800 watts. 5,000 cycles, LCD display panel on the front, which is pretty
1:55
neat. There's a picture of the display panel, and they're hinting that it could be used for
2:03
probably other things like running a CPAP machine or a breathing machine. Actually, that would
2:08
probably be one potential use case for it. Four outlets, 515p 15-up outlets, and it does say it carries
2:17
some yield certifications on the battery. So the battery itself is carrying these certifications here
2:22
Let check those out At least one of those certifications is a yield certification here This is a certification that provided by the Underwriters Laboratory And as far as I know in order to check those
2:35
you need to search in their database to see if the products is listed. As far as I can tell, they do appear to have a UO listing, so that's good
2:41
Sometimes I just check to see if they actually have it, and it appears that they do
2:46
And here's a list of the battery packs or components that they have certified
2:50
So very good. Unfortunately, I have not found a convenient way to search
2:54
the UL database, so I'll just use the information that Golden Mate provides on their website
2:59
On the Golden Mate website, there is a specifications list, and I noticed that the AC input
3:04
voltage is 90 to 140 volts. Therefore, my hope is that this UPS will actually be able to convert
3:10
the voltage if it goes too low or too high, but hopefully that feature is included, and it seems
3:15
like they're indicating here that it is. It also has a pure sine wave output, which is excellent
3:20
You don't want to have a UPS with a modified square wave or square wave output. It's just not a good
3:24
idea. It's better to have a pure sine wave output. 89% efficiency. It has a fan in it. And it says at 400
3:31
watts, it can run 30 minutes. That's fine. They also list the harmonic distortion at less than or
3:36
equal to 5 I assume they mean total harmonic distortion of the inverter output And so it be interesting to know exactly what that figure is but I sure it good enough for UPS backup and conversion time less than 20 milliseconds I believe that means
3:50
transfer time so how long does it take to react to a power outage and that's just a guess on my
3:55
part but I'm pretty sure that's what that means okay let's go ahead and test this UPS and see what
4:03
it can do now this company does pride itself in quality and they have a lot of certifications
4:07
and certificates, and the unit does look. I must say it looks fairly well put together
4:12
This would fit really well on like a equipment rack or a shelf
4:15
because it's rectangular. I really like that. They rounded the corners, but it's still a rectangular form factor
4:21
and that's really what it needs to be. Eventually, this is probably going to be on some kind of equipment shelf
4:26
but for right now, I'm going to test it on my workbench. In order to test this unit, I have to power it on
4:31
Just to be clear, a UPS, uninterruptible power system is designed to sit between your AC mains power and your
4:37
computer equipment and Wi-Fi router. That way, if the power goes out, it'll keep working
4:42
It also protects the computer from data corruption if it powers off suddenly. My workshop here is running off of batteries
4:47
solar panels, and inverters. It's an off electrical grid system. However, it's the exact same thing
4:52
If my inverter goes down, this GPS would step in and keep my computer equipment running
4:56
until I'm able to intervene
