Guys this thing is huge check it out guys we’ve, got a regulated DC output, a 1000 watt pure sine wave inverter state-of-charge meter in the solar charge; controller input, so you know, have an anderson, connector and then their typical connector that they use For most of their solar panels, and up close, it looks like all the other models, so nothing very new on the outside, but look at how big this thing is.

This is huge. We’ve got the 291 hour, which is the same size as their 241 hour. Look how big this thing is especially from the side like this thing is massive, but overall everything looks the same. It’s literally just a bigger version of this, so this has an MPPT, but the max input voltage is thirty volts.

So let’s, hook up a power supply and see how much power it can pump into this thing. So now we have 30 volts and we’re gonna plug it in – and I hope nothing blows up and this mimics a solar panel by the way, so the manual states that it can have a max input of 24 volts at 8.

3 m/s. So the max I’m, getting is 176 watts, so whether you put 200 or 300 watts of panels. This is the maximum that you’ll, get for the input and it says on the manual that can handle up to 8.3 amps. But right now we’re at 7 amps, but that’s because we’re at a higher voltage.

If I decrease this, the amps will go up. So let me show you well guys the amps are not going up. The max I can pull is 7 amps. I think it might be for both of the inputs combined the power supply, number 2 and second input.

Let’s, see what happens it’s. Only eight look at that. It’s switched over to the other input, so you can only do one input at a time, but both inputs push about the same amount of current. They’re only off by 0.

1, and it could just be the accuracy of these power supplies. Let’s, see what voltage is required for it to be charging all right. There’s, a 17 volt, which is the working voltage of a 12-volt panel that’s, where it substantially decreases.

So I would recommend getting a solar panel with like a voltage open circuit of 22 volts. If you want to charge this quickly, so you check it out guys the moment we go below 17, it drops to 3 and then 2 two amps, so make sure that you have a higher voltage, 12 volt panel for sure.

So let’s. Take the max charger, a in watts and divide it by the watt hour capacity, and we get five point six hours, that’s the fastest, that you can charge the jakhary with solar power. With this input, now let’s.

Add their AC charger and see how fast it charges it says they can push eight amps at 24 volts. So maybe we can get eight amps. This time we’re only getting 163 watts that’s, a bummer. So I guess it’s faster to charge it with solar, so yeah, I don’t think this is pushing eight amps at all.

That’s a bummer, so these little power supplies were cranking out more power than their dedicated AC charger. So yeah Solar is preferable in this instance. What I’m thinking is that this has to be at an extremely low state of charge, and then all of these will push eight amps.

So if this is it like zero or 10 % state of charge, then it will charge at full speed, but around 32 %, it doesn’t and it will decrease the higher the state of charge so yeah. I think to expect 170 watts for a charge rate is fair, which is around 6 to 7 hours, but because Sun can be unpredictable.

I would absolutely over panel this with like 200 watts of solar panels, and it would take about one to two days to recharge it when 900. A thousand wants you guys. Oh, this is weird look at this 1800 and then they drop to 400.

That was strange. I’ve, never seen that before on a jakhary, so I noticed there’s a lag time on this shunt it takes like 20 seconds or so until you get accurate numbers see. I just turn this off and he jumped to 740 watts, but we only have 400 watts connected right now, so that’s, really strange, let’s, disconnect everything look at it takes a while.

Let’s, see how long it will take guys. It’s been like 30 seconds and it still isn’t changing okay. There we go yeah there’s. Some serious lag time on this power meter, so it is accurate, but it takes like 30 seconds until you have a good number.

Now let’s check the voltage of the DC receptacle and the voltage output is 13 point three volts, which is nice because we’re in a low state of charge. So this is the perfect time to test it when it actually matters, let’s, compare it to the other jacker ease we & # 39.

Ve got thirteen point three, so it’s the same and this one’s at a low state of charge as well. Now let’s figure out the inverter efficiency, because I think this matters a lot when you have a smaller system like this, and this is a more consistent load than the heat gun.

The heat gun can fluctuate quite a bit in 398. Divided by 414 is 96 percent efficiency, which is absolutely incredible, and let’s just disconnect the input and see if it changes it, and it does change and look at that guys.

So this is actually the output of the AC receptacle, so I can’t actually calculate the inverter efficiency unless I did a full capacity test with the watt, our capacity rating versus the AC output. So that means it is not 96 percent efficient.

Now, what we’re gonna do is see what it favors more AC charging or solar panel power. It’s, actually preferring the AC charging method, but we’re only giving 164 watts. So let’s. Disconnect this and see what the amperage is on this one look at that 176 watts.

So yeah you can charge faster with the solar input, but it does seem to favor the AC charging. Let’s plug this one in one more time. Look at that it switches over to this one, so it does favor this side, even if it charges slower it favors.

This input that’s pretty interesting, and I just disconnected the Anderson and put it back in and it still does not favor it. So yeah that’s, a pretty interesting little test huh. So now we’re gonna charge it up and do a quick capacity test.

Now the jakhary is fully charged and it took a long time a trickle charge for like another hour, we’re gonna pull 200 watts for like five hours to get an accurate assessment of the capacity and the numbers will fluctuate over here.

But the kilowatt hour counter will give us an accurate assessment, so we’ll, come back in a few hours and see what numbers we get. Also, when I do these tests, I have a security, Wi-Fi camera and I stick it in front of the meter and I can see it when I’m, not home.

So I’m gonna go to lunch right now and I can watch it when I’m gone. So is that great? So the total we measured was 830 watt-hours, divided by the total capacity, and you get 82 % for the inverter efficiency, which is pretty typical and Jackie’s, always pulled full capacity, so I bet actually pulled further than what it’s.

Rated for but the inverter efficiency is probably like 80 %. Now that we’ve done our testing. Let’s, talk about if you should actually buy this model, so this model in particular, I’m, not a big fan of, even though I like jakhary, and these are very durable and I’ve taken these apart.

Put them back together again and ran them for years, and they’re great units. I think that this one is underpowered for the cost. If this came out like a year ago, I think people would go crazy, but now there are better options for almost the same price: for example the Eco flow Delta, this charges in one to two hours.

This takes five to seven hours to charge. There is like no comparison and this one’s, only a couple hundred dollars more. If you’re spending a thousand dollars – and you can get this one instead with almost double the inverter output in 1/5, the charge time.

Why would you buy this one and I like jakhary – I really do but compared to this I would go for this. If I’m spending, my hard-earned money, I would go for this for sure. Also the input voltage is only thirty volts.

This one sixty okay, you can string your panels if you’re using this for, like an RV or van. I would not use this. I would use this one instead for sure you can connect 400 watts to this. This can only handle 170 watts max if that’s available.

So you, if you connect 200 watts that’s. All you’re gonna be getting there’s. Also the Blue Eddie. This thing can handle 500 or even 600, watts of solar panel input and the new one can handle like 65 volts of input.

So this thing can charge like way faster than this with solar and it’s faster than this one too, and the cells that are used in this are very high quality. I think the number one selling point that the jakhary has is that it’s lightweight.

This thing is only 22 pounds. This one’s 30 pounds. This is actually the 2.4 kilowatt hour model, but the smaller one is like 30 pounds. As well, so I think the biggest selling point is the, but everything else is just very limited.

Also, when jakhary came out with a regulated output, we were like oh wow, that’s, amazing, but now all of them have it. So it’s, not that special anymore and all of these have quick charge and USBC. They all have receptacles on the back for the AC output um.

This one has six receptacles. This one only has three. This one has two on the back, but this can only handle a thousand watts this one’s great for a long term use, but the inverter output is horrible, but yeah eco flow Delta.

It has everything and it’s. Only a little bit more than this, I think if this jakhary was only $ 700, people would go crazy for it. That would be a perfect price point, but for a thousand dollars I wouldn’t spend my money on it personally, but I must mention that jakhary has better customer service than Eco flow Delta, and also this one’s great for long Term use the Eco flow Delta has its own problems, which you can watch out my other video, but it’s, a good unit anyways.

These are more for like camping. If you want an actual solar power system, even though this one’s underrated, this one will last a very long time for charge cycle life. The charge cycle life for this one’s, not that great also.

This is sponsored by all of these companies. These were all sent out for me to test and review, and that’s, pretty much it. I was actually pretty bummed about the input the most because everybody complains about how slow Jack recharges I wish they could just put like 300 watts that would make everyone’s, life, better anyways.

I hope you guys liked this video and I will talk to you later. Bye,
