 What's up guys? My name is Rick. I'm a heating air conditioning refrigeration technician that's been asked to do a review on the Opus 1800 watt power supply. I previously did a review on the 1200 watt Opus power supply, which I have right here in front. So looking right behind it is the 1800 watt one that we're going to be going over. This 1800 watt power supply is going to give you 600 more watts of power than what the 1200 watt one did. Now you may be asking yourself, why do I need 1800 watts of power supply? I don't know. Why do you need a V8 engine? Why do you need extra food in the cupboard? It's the same thing. It's nice to be prepared in case you need it. Extra wattage is extra wattage and when you need it, you need it and when you don't have it, you're going to wish you had it. It's summertime and what better time than to have outdoor grilling and parties and things like that where you might need power out and about, but you really don't want a loud generator or have to deal with gasoline getting spilt in the vehicle as you're traveling. Well, one of these power supplies might be what you're looking for. In this test, you can expect me to check the DC performance, whether or not it provides the wattage that it's rated for. You're also going to see what the total watt hours are in the battery, whether it be a DC drawl or whether it's an AC drawl. And by doing those tests, you're going to find out whether you're getting value for your money. I've been reviews on a couple other power supplies. What I like about this one is it's pretty simplistic. There ain't nothing real fancy on it. There's no programs, which the programs that I've seen so far really don't do a whole lot for you. It doesn't have pass through power, which is the only thing I don't like. So if you want to run your computer off of it in standby mode, it's going to actually charge the battery while it's pulling power off the battery versus actually passing it directly through on the 120 volt, 110 volt circuit. So let's take a look. Let's do the test. Overall, I feel confident this device will do you a good job. Let's go into the testing here and see what exactly it can do. All right, guys. This was just delivered. This is the Opus 1800 watt portable power station and the solar panels to go along with it. And this right here is the 200 watt solar panels. So let's go ahead and get these opened up. Let's get them hooked up. As you guys know, FedEx should have a class action lawsuit put against them because generally they can't deliver anything without purposely trying to break it. Not a real big into the unboxing thing. So really the only reason why I'm showing this is because when they pack them good, you know, your stuff's not going to get broke in the mail system. And it lets you know that you're going to have to go through the hassle of getting it swapped out again and again. Looks like they sent me two individual 100 waters. These are really small and easy to pick up coming in at the top here. As you can see, it's just like their 1200 watt one that I did. Super heavy insulation around here to help protect it. I think we can just push down like that and off it comes. So this is going to be very similar to the 1200 watt. We've got a light right here on the back. We've got a pretty simplified layout here on the front, which is really easy to use. Two output jacks, 310 volt outlets, 12 volt, and two DC outlets. And we've got two USB-A and two USB-Cs, 1860 and 3.0. So we're going to be testing all these outlets now that I have some new testing equipment. We're going to be able to test the waveform. The panels feel pretty, pretty strong. Don't feel bad. Like I said, pretty nice stitching all the way around. Pretty nice. I like that. Unzips exactly the same way as the other one. Same type of plug. And we have another Y jack here. This does have nice rubber feet on the bottom. This is supposed to be a lithium phosphate battery. Now on the box, it said lithium ion, but down here on bottom, it is lithium phosphate. So that's good. That means you're going to get more charges. All right, let's go ahead and get this set up. Like I said, you've got pull-out legs here. And these fold out. We want to point this towards the sun. Oh yeah, this one does have the sticky protectant on there. So good. They both did have it. Maybe I'd reopen the second one twice. And it just goes to show you that they're being overly protective of the cell so that it is protected for when you get it. These are not very big, so they're going to be easy for you to transport. After playing with some really big solar panels, it was kind of difficult to carry and set them up, especially if it was windy. This seems pretty simple. Okay, here we go. And here's our power plug. Now they did make it so you could hook two of these together underneath one plug. They do have two input plugs. So if you wanted to do two types of charging at the same time, and that is quite a cord on that bad boy. Look at that. That is every bit a 15 foot. Sweet. Because half the time you don't really want your portable power supply out here in the sun. So let's go ahead and plug in one. Go ahead and plug it right into this input here. See what we got here. Looks like it is coming in at 44 watts. Sun is out. Let's see if we can reposition that a little bit better. And then we'll hook up this other panel here too. It's really critical that you get really good placement with the sun. There we go. And we are at 549 in the evening. That did jump us up to 50, 53 watts, 54 watts. These do have little hooks here that you can hook it on something, whether it want to be a wall or whatever. Everybody's situation is going to be a little different with the way they hook it up. Why they hook it up the way they do it? I think if you're going to go with portable power supply, if you're going to be out camping and stuff, I mean this is kind of a given unless you're either going to charge it in your car off the 12 volt or off the solar. I mean it's just kind of a given. I think it's just a good idea to do the solar cells. Just makes it a lot easier to recharge. So we can plug this other one right here in beside it. There's 90. We've got it like that. What you can do with that Y, is you can unplug them both. And I'm going to say that these are probably going to be put in parallel. So there's one and there's the other. All right, jumping over here, we're at 94, 97 watts. So we're barely getting half the power, what they're rated for. We're pretty average sun. I mean it's no clouds in sight. So we're only getting 90 some watts. See if that helps at all. Yeah, we're up the little bit. So we're at 105 now. Like I've always said, we don't have the strongest sun here. Even with some of the other brand solar panels that I've been testing out, they have not been really all that strong compared to what they're rated at. It is charging. It's doable. It's definitely doable. Here is the wall outlet and the car adapter. The car adapter is straight off the accessory and right into the plug. Nothing special there. And the power brick is actually is using just the usual plug there. So pretty simple on that. This one here looks like we have three amps going in and we have up to 8.3 amps going out at up to 24 volts, 199 watts. Here's the manual that comes with carefully selected monosilicon solar cells as a target intelligent recognition chip. Prevents reverse charging. So it does come with a basic manual here. It is 1800 watts of portable power. It's going to take 15 hours on the car charger. Three different ways to charge it. 200 watt AC adapter would take about four hours to full charge. We'll take at least three and a half hours to charge with the direct sunlight. With direct sunlight three and a half hours to full charge. We do have a couple things here in the book that you'll be able to power and how many times you'll be able to do it. You guys can go ahead and screenshot that right there and take a look at it and hit pause. Here's some other technical jargon far as the output frequency along with the voltage and amperages. So go ahead and just hit pause if you'd like to look at that. The battery is 1488 watt hours. 46.5 amp hours at 32 volts. Does have overheat, overcharge, undercharge, low temperature, high temperature, the whole nine yards. Pretty simple. And like I said we're not getting real strong sunlight. We're at the end of the day here. It's about 620. You want to get this stuff during the day time. So we're coming right in at 90 watts. Now we can compare that to the other generator over here. This is also 200 watts. Two 100 watt ones combined together right in at 91 watts. So we're going to get 91 watts whether we're using two 100 watts or one 200 watt panel. Two different manufacturers mind you. So that sun although looks kind of bright is not bright enough to really generate the maximum potential of these panels. So we're going to go ahead and get started here with some load tests and voltage tests. We're right at 109.8 volts and 109.6 on the amp probe. Amp probe is owned by Fluke now. The amp probe is a power meter here. It can do total harmonic distortion. So we're going to go ahead and go into total harmonic distortion. Currently right now we're at 0.4 percent on total harmonic distortion. That's with the 109 volts. We are not under load yet. So let's go ahead and start off with the low load first. All right. Testing out the meter function. So we've got 596 here. We have 590 there. So it's fairly accurate. It's within six watts. Looking at the voltage of scale here 108.4 versus 109.7. So once again we're very close. Now go ahead and jump it up to the 1200, pulling 10 amps of current. Got 1170 there. 1185 here. Going back down to the 1174 watt area. We are at 1 percent total harmonic distortion. We're holding in there consistently at 109.7 volts frequency right at 59.83. Coming over to the oscilloscope you can see our waveform is beautiful all the way to the top and down. Cannot complain a bit there on that. Okay jumping it down to 100 volts scale. You can see it still once again perfectly smooth. Still running like I said at 1 percent total harmonic distortion. So in other words this is going to be perfectly safe for any of your electronics. As far as frequency is concerned it does look to be pretty accurate there. 59.82 versus 59.87. I know this one sometimes is off by two tenths of a percent. That's still an acceptable level. No problems at all there on that. All right what we're going to do now is we're going to measure what the actual SPL reading is of the fan. We've been running a 1200 watt load now for about 17 minutes. We're going to stop the load and we're going to see what kind of noise level the fan cuts off. It's a low pitch noise so it's not really bad far as noise is concerned. Right there's three foot. Now you know not coming out hot at all. Pulling in on the right side ejecting out on the left and it's shut down. Actually dropped down to a lower level. All right I'm going to give you a second here to go ahead and get a screenshot of that so that you can see what our input and output voltages are. This is capable of 1488 watt hours which we're going to find out how close it can actually get to that and then we'll do the math on that. There will be a reserve capacity so you will not hit the 1488. We just now shut off on the air code which is low voltage. We got a total of 1.193 kilowatts and this is rated for 1488. It kept a reserve capacity about 11 percent. Here we do a little bit basic math 1488 minus 1193 gets you 295 divide that into 1488 which is a 19 percent loss so it's 81 percent efficient. Now this was the very first time that I'd done this test on it so it has not been cycled prior to and this was the very first test. So we can always do this again. It's going to take a little while to recharge which is probably one of the only things I see as a downside is this does use a brick and it's a little slower than some to recharge. To recharge this like I said we have a charging block here. This thing is only about 200 watts. Go ahead and plug her in see what our incoming wattage is going to be at and they say this could take potentially four hours but they make it sound like that's if you're using two different chargers at the same time which just only comes with one so essentially this may end up taking eight hours to charge. You can turn off the AC powers and still allow it to charge. Some of the different power banks out there do require you to leave it on and you cannot shut the AC off. This one here it does. The display is really easy to read and it's very clear. Now we're going to go ahead and test out the 12 volt DC plug which is rated at 10 amps of current starting off the top there right at 9 amps current which we look up there we're right at 110 watts. We can go ahead and slowly push that up. 9.2, 9.3, let's go ahead and run it right up to 10 amps which hold right in there at 11.5, 121 watts. The screen does go to sleep to save power. The device is running as a cooling fan. We're going to slowly go up until it trips out and you see right here that we're running at 121 watts 127 there so they give you about one amp of current overrun and it does go into alarm mode here to turn the alarm off just hit your DC button turn it back on and you're good to go which that wire is starting to get warm so that's not really the greatest plug in the world that I've got there but it does prove that it does 10 amps of current. Our next test here is on the USB-C 18 watt you can see that we're running right in there at 5.1 volt you see the wattage right here that we're at says there are 11 watts right there we've got 10.5 watts here continue to drive that up to the 18 mark oops it didn't like that like I said that is rated at 18 watts right there now that was not the device shutting down that was the protection circuitry here the cutoff voltage maybe my issue then take that down maybe three volts all right now we're checking out the usba these are qc 3.0 if you look here we're rated at five volts at three amps they do play with the voltage to get the different amperages that they're wanting to state right now we're running right at 13 watts we're pulling right at 2.7 amps and this is rated for like I said up to three amps and we are running at the five volt scale so we can go ahead and take that wattage up 14 watts is where it drops out at if we go back in there you can see that we're pulling right in at that 2.6 amps so we're coming in a little bit low on some of that right there on the usba we're going to try another different cable even with the longer cable here we're still right in about that 13 watts area well so we're getting right in that 2.8 amp area voltage is staying in there at 4.6 we're at 13 watts that's about as much as we're going to be able to get out of that usba now we do have another meter here that we're going to test it out with the computer we'll see what kind of uh voltage and the amperage we get with the actual pd power system that is special encoding that works with certain phones so we do have a device here that should be able to read it as it's charging as you can see here we are charging now at 8.9 volts which the other tests show that we were only at five we are coming in at 0.99 amps so we're right at one amp and wattage wise we're supposedly at 8.9 watts which we're right in here at seven watts now to get to 60 watts we may have to try the apple computer to be able to get that so it does up the voltage like they claim yeah it's just going to be a little difficult to be able to trick it into doing a flat load you really need a communicating phone or device that actually is going to communicate with that pd system doing some further testing here off the usba we're now running through some conversions so that i could get this remotely down here make it easier to see what's going on you can see we're running right at 4.7 volts two and a half amps 11 watts which we're right at 11 watts there the load is actually being provided by the actual device here and we're right at 11 watts with 4.4 volts so the voltage is within a small amount the amperage is what i'm really looking at right at 2.49 so we'll go ahead and stuff this up another notch it's 13 watts it just wants to kick out so it's not the device kicking out it's actually this device shutting down all right now we're testing out the macbook pro we are at 95 percent so we're coming in at 20 volts just three amps 60 watts 60.3 watts so it is capable of doing the 60 watts that they have it rated for let's go ahead and plug it in over here at 18 watts see what it does here on this one on this one here we're writing at 12 volts 1.4 amps and are 17 watts area we are getting the wattage that they are ranking it at so we do know that these are actually putting out the wattage that they've got what we've got going on here is basically when they change the voltage the amperage stays lower but you're still getting the watts so that passes that test and then if you're kind of curious what it does far as the voltage amperage and stuff like that you can actually see how it's charging right there it's modulating and pulsating the actual voltages so it is actually doing work that it's rated at which is kind of interesting to be able to see here all right so right now let's go ahead and find out how many watt hours we can get out of this battery so let's do a load test on it and run it till it's dead now we're going to go ahead and do a load test here on the 12 volt dc 5521 plug we're going to go ahead and we got everything zeroed out go ahead and do it at the 10 amps that it's rated for we had to do some rigmarone here with the plugs just like I did the last test but it's capable of doing the 10 amps we can go ahead and go a little higher just to see what happens we see that our voltage is hanging right in there 11.6 there's 12 amps this is going to cause it to shut down on the actual device itself so it is able to go at least an amp over but anything more than that you're going to have a shutdown once again turn it off turn it back on we're back together we're going to go ahead and do eight amps of current right there and we're going to run it until it goes dead nice thing about this is it'll keep track of it and we'll look at it when we're done all right so we just finished testing the dc side of the battery as you can see right there we're right at zero percent so it goes to show you that if you're pulling less amperage at a lower rate that will use up the whole battery so what we came in at was 1127 watt hours took 11 hours and nine minutes to run this down and that was pulling in about eight and a half amps area so when we do the math here it was rated at 1488 watt hours it tested in 1127 watt hours giving us a difference of 361 divide 361 into 1488 comes into a 24 loss or better yet 76 efficient not horrible but not the greatest I've seen now you got to remember too though that we did some of those other tests in the beginning there on the usb but it really wasn't that extreme that's what we came up with on the watt hours for the dc section only we did pull that off of the 12 volt 10 amp plug here and right now we are starting to recharge so what is my final thoughts on the 1800 watt power supply it is what it is it's a power supply it's not a generator so it does not have indefinite power it can be recharged it obviously takes a little bit of time for that you can use the solar cells or you can use a battery off of your car to charge it it provides the power that they rated it for they've been truthful in their ratings and I think it's a well-built unit from what I see now have I tried to drop it out of the back of the truck doing 40 down the road no I haven't have I tried submerging it in water have I tried it out in a rainstorm to see whether it's going to fry itself no I haven't but if you use it the way they describe to use it I think you're going to have quite a few years of useful service out of it the warranty on it is stated below so if you're interested in picking one of these up I have links down below in the description area I appreciate you guys taking the time to check out the power supply if you like to help others contribute to the review process and you have any comments or questions please leave those down below I'll try to get back to you on those and until next time guys I appreciate you watching we'll catch you on the next one later
