Always come to Jason for the Best Power Station reviews.

[@MrMasterSpam]

I have a small power station of theirs I like a lot and have just ordered one of these to power my off grid garage/ light workshop I'm building. All the reviews I've watched made this a good choice for my application.

[@jadriendeleon6623]

Do you have any input on how it’s lasted you so far?

[@johnkenny2403]

Very cool use of the oscilloscope for the UPS cut over time.

[@Jasonoid]

I'm glad you liked it! It was pretty cool to figure out how to record it 😎👍

[@wt9653]

125 watts continuous draw from single refrigerator 😮 I have a new 2022 refrigerator and 2020 freezer. They both draw only around 50 watts continuously. 200 watts when the compressor kicks in. 325 watts during defrost. The freezer is a manual defrost.

[@cyberspark1341]

Another great review. Actually demonstrating the devices sets you apart from so many youtubers who just sit there repeating the information from the manual.

[@Jasonoid]

I'm always looking for better ways to measure performance!

[@jadriendeleon6623]

You’re the best Jason, you helped me pick my first power station and start my own lil DIY solar array, thank you for everything you do, you have no clue how much I appreciate you.

[@johnperry5960]

Fantastic video as always Jason

[@KatysCampKitchen]

Fantastic review!!!! This thing is a beast!!! The oscilloscope testing is great! Katy

[@Mega1andy2]

without having the ability to control the wattage from the phone app, is kinda of a bummer that i was looking forward to getting this, im really hoping that they will do this in the next firm-ware update! oupes, please, get that updated so customers can control the wattages via the app, incase the fuse does get blown out, from older houses, 900 watts is still a bit to much to say the least! 300 watts? i can see that they could go low as 300 watts, and having the max to its maximum! thank you!

[@user-wp1zw4eq8m]

My goodness, what a thorough review! Just awesome! You are a trailblazer for the quality and depth of your reviews! Rock on Jason!

You did a great job! I think it would be a good unit to have in an emergency.

[@tech53tjw77]

Great review!! I'm definitely looking for some holiday deals for this model.

[@Jasonoid]

I actually think it's on the Black Friday sale right now, with my 5%Off discount code the price is under $2000.

[@JimMcPartland]

Thanks for another great review. This is one of the machines I've been really curious about, and it's big brother the Mega 5.

[@Jasonoid]

It would be interesting to compare the cost difference on both models. The Mega 5 has a slightly bigger inverter at 4000w, so not a much bigger advantage there. The battery on the Mega 5 is a bit bigger at 5120wh. I think the portability of the Mega 3 is spot on, it can still be lifted (carefully) by one person haha

[@keithbar19741974]

Love your videos, would love to see you get into testing the next sizes up. Specifically 240v units such as Anker SOLIX F3800, Ecoflow Delta Pro Ultra, Titan 240SP, Inergy Flex P3

[@Jasonoid]

I am planning to test the EF Delta Ultra! Should be a beast! I have previous videos on the AC500. Ill try to other options in the future.

[@StevefromOhio1972]

Another great review. I like the am radio interference test you do on the ac and dc. I like how your new tester can test just how fast the UPS switches over. I have never seen that before. This looks to be a solid unit from OUPES. The best feature in my opinion is the 150volts of solar input. You can run your arrays in series. I hope OUPES can get the little bugs all worked out with this one. It's a nice power station.

[@Jasonoid]

Thanks, Steve! With future firmware updates on the way I'm sure they can work out the bugs solar panels connected 24/7.

[@lynnbb]

Good Show thanks Jason 💐😎

[@jimmay8627]

Big 👍 on the oscilloscope upgrade. This one's a bit overkill for me, but it's great to see more downward pressure on prices as component prices drop and more features make it to the budget models.

[@alaingoyette7103]

Awesome review. I was impressed by the generator performance for the price but the noisy fans certainly put a wrench in my wheel to buy one.

[@Jasonoid]

I agree, the fans are quite loud. It just depends how close you are to the power station.

[@markmonroe7330]

Excellent presentation. Many thanks. Lots of DC and 12v output options. Much better than Bluetti or Jackery.

[@Jasonoid]

I love when companies include high DC output

[@user--PM]

very nice to see the switchover time on the ossicilope. looks like 1 full sinewave missing. looks like the switchover time on your screen is 20.10ms, very nice. i believe this will make an extremely valuable tool for testing these power stations. this would be a beast for RV applications, and one could put solar on the roof of the RV to help recharge it. hopefully they address the start up issues with solar charging in the morning. very interesting thoughts on the app, i am sure companies are listening and hopefully take your comments to heart.

[@Jasonoid]

A full sine wave is about 16.6ms from peak to peak, so just a tad longer than one full wavelength. I'm hoping for data logging eventually in these apps. That information would be very helpful :)

[@adriftatlas]

I wonder about the measured UPS transfer time of the some of the other units. In many of your tests the computer restarts at least once. That suggests that previous units that were rated for 20ms were likely taking longer than that to switch. I am also interested in best/worst/average UPS transfer time. It is my understanding that it can vary depending on load conditions and timing of the sine wave. Keep up the great work!

[@DYT-jx4jp]

Thanks for the review efforts; so much great testing, thoughts shared!! There is so much content packed into this video vs its length and the editing to go with that; wow!! A great start to Friday watching this, thank you! This part of the comment is more an overall thought from a different person and video and your comment from a recent video. On the grading sheet, perhaps change "F" to "P" for passing and leave "F" for a true failed unit. I remember you saying basically "all" units you have tested (and plan to test) have been acceptable/safe with tradeoffs. Seeing the "F" I concur with the other commenter doesn't convey that to me at least with a quick glance. I know your reasoning, so no biggie to me. Just perhaps an easy change to set yourself up for a "true" "F" if it ever comes. Ok, this part got way too long. 😢

[@Jasonoid]

Some power stations I would consider a "failure" after testing due to failing many tests, but as you suggest most of them don't deserve a "F". I'll work on changing it up so that it's a "satisfactory" instead of a failure. Maybe I can use a 'S' or something. A pass would be too good for the ones that fail multiple tests.

[@DYT-jx4jp]

Ah, yes, "S" (or something similar) is much better than "P"!! (The original commenter might have said "S" too.) Thank you for considering and catching that!! But, maybe some units do deserve an "F" if they have a bunch of failures. I had not realized that piece. I apologize on all of this, I thought an easier change. I didn't mean to give you another thing to do. 😢😢

[@user--PM]

totally agree save 'F' for power stations that are Failures, not ones that are not quite up to snuff but passable.

[@shelley131]

Don't really have many negatives checked on this unit, if any it is minuscule and that would be the display. Don't want to figure out anything. Great review sir.

[@Jasonoid]

It's a decent model, especially for the price! Thanks for watching 😁👍

[@mannys4036]

Excellent review. I am impressed with the DC output and solar input capability. I agree with the klunky way you have to press multiple buttons just to adjust the charging rate. That would get old real quick but overall if you could tolerate the noise it is a fairly good power station. I am not a fan of those bulkly expansion battery connections. Other power station expansion battery connections are evolving to flexible cables that does not inhibit space around it.

[@Jasonoid]

With just a few small changes this would be perfect!

[@michaelbeatty130]

Wonder if anyone has investigated upgrading the fans for this or other noisy stations like Ecoflow Delta 2.

[@Jasonoid]

@@michaelbeatty130 there's a couple videos of someone upgrading the noisy fans on the new river 2 models, I bet it's possible.

[@johndelabretonne2373]

Jason, another awesome review. Thank you! Although this is a nice price per watt hour, I'm still thinking that I'll wait for three Pecron E3600LFP to come out for a similar value. The fans are a real deal breaker for me...

[@Jasonoid]

I'm excited to learn more about that Pecron unit for sure!

[@nortonknows]

Do you plan to do a review on the Mega 2, I may base my decision to buy it when it releases on Monday on this review and the one you just did on the L. There is only one video out there on M2, it would be nice to know if they improved the fan noise. I really appreciate all the hard work you have done, thank you!

[@Jasonoid]

I don't have plans to review the Mega 2... in the few months at least.

[@jeffwrightsman5265]

Do you have any thoughts on keeping the OUPES 3 warm in a van during a Wisconsin winter? I thought about using a large tote with a heating mat (from my plants) with a temp controller to keep it above freezing. I have the ability for shore power so am not thinking of using the OUPES as the power source as I would assume it would not last very long.

[@Jasonoid]

If you could find a large ice-chest or insulated tote that would fit the Oupes Mega 3 I think that would work well.

[@californiatarheel6658]

Hey Jason, I’m debating between the anchor 3800, and the mega 5. Have you looked at the mega 5? I really like the solar voltage input, and the various output options, but I’m unsure of the quality. Compared to anchor, I’m sure it’s not as good, but what are your thoughts?

[@teuton6167]

Great video. Are there any expansion batteries available for this one?

[@Jasonoid]

Yes, they offer a 2048wh expansion battery for this model, it's visible on their website.

[@Chaseosa]

Would love it if you could review the Yoshino power stations. They're solid state batteries and much lighter than these others which is important for me.

[@Jasonoid]

I thought about reviewing the Yoshino models but the solar was just so limited. So for the price it wasnt super attractive.

[@realeyesrealizereallies6828]

Appreciate the thorough testing, not sure knowing the micro seconds for the UPS is necessary, either it works or doesn't, that would suffice..But, I understand techno addicts..As I'm a self sufficiency addict, and there is some cross pollination there...I own a small unit from Oupes to run a diesel heater/ compressor fridge in my garage, and it has the same issues when plugged into solar 24/7..Sometimes it works like a clock for a week straight, and sometimes I have to unclip an MC4 cable and plug it back in to reset it, no big deal though..And I don't care about fan noise,I have lots of loud devices, not sure why that is a thing..People are in for a rude awakening.

[@Jasonoid]

Thank you for your feedback, it's helpful!

[@OnusBones]

The 7th cranial nerve damage I have made it very hard not to drool while watching this one. Very nice indeed. You tested the Anderson 30A 12V output for not shutting off; does the 12V socket similarly not shut off? This is where a single compressor-cooler would likely be plugged in.

[@Jasonoid]

Both 12v outputs did not have any 'auto-off' settings. Sorry I didn't clarify that!

[@markk171]

I am interested in using this as my sole power unit for my RV. The 30 amp AC outlet, I get how to use that. What about the DC side? Can I do something like this for the DC side: Disconnect and remove the RV house batteries Connect the 12v/30 amp Output on the Oupes directly to the 12v battery connections on my RV turn off the RV charge converter (so it does not try to charge the 12v battery system) Use the Oupes to power both AC AND DC on my RV. Does that sound doable? Also, IF it can be done, are there any problems that might arise when the RV is attached to the tow vehicle via the 7 pin connector (I know the 7 pin has a change pin to try and charge the RV house battery and if the only downside is the 7 pin connector cannot charge while connected, no big deal). Thanks...great video on this unit. Really would like this unit for my RV especially if it can run both the AC and DC circuits. Oh yea, and via the "smart app"...I did not see a way to control the AC charging input...manually on the unit its only High and Low? Is that it? I have a portable Hionda 2000 generator that could input 1600 watts input. Using only 900 watts on low setting seems to be a bit of a waste.

[@claytonyoung1351]

$2099 on the site right now. Not bad. Still going with AC300, but this is a nice generator.

[@Jasonoid]

With the 5% off discount code the price drops below $2000. Appreciate you checking out the video, Clayton.

[@johntorrence2195]

Good video I noticed when charging mines at 900 something it cut off and starts again do yours do that they oupes say because of the voltage going up and down

[@Jasonoid]

Mine was only cutting out when charging at the higher speed. It seemed it work well at the 900 watt speed.

[@JimMcPartland]

Watched the video a second time. Did you talk about the expansion capabilities?? How many expansion batteries can you attach?

[@Jasonoid]

I did near the end of the video. I think you can hook 3 or 4 for huge system. I was not able to test the functionality since I don't have one.

[@GoodmanMIke59]

The Hysolis Apollo has a dark start, from zero it will be set to come on at a prescribed present state of charge. ... Don't think you charged this thing up from zero to see if it would kick on. Will it

[@GoodmanMIke59]

If it's 3600W continuous, can you run 30A of 120V and still run a single 120V (5A) outlet, minimum amps at the same time? ... or by extension ... a bunch of DC at the same time?

[@GoodmanMIke59]

I intend to leave this at an off grid, off-site cabin, 1 hour from my home. The loads should never drain it if I go back up frequently enough. ... Have they updated the firmware for charging 24/7. Will it DARK START WITH LOADS BACK TO POWERED UP if the power station is at a set prescribed limit of, say, 20%?

[@GoodmanMIke59]

I have a grid-tie, battery backup currently set up in an off-grid system without the panels on the roof. Basically it's a backup of about 4 days that I can charge by home or generator. I've been doing this since about 2011. This is my second set of flooded lead acid batteries. I am thinking about buying this with one expansion battery. Depending upon the response I get from you I might use your store. Have you had a chance to test the B2 battery, particularly with regards to solar input? I currently have 12x - 235 watt REC panels that are no longer on my roof. VOC is 37.4V. Impp is 7.9A. the panels are from 2011 and have about 11 years of service with the last 2 years in storage.. I was thinking of 4S/2P to maximize input voltage, maybe put the remaining four panels on the battery ... Or would it be better to put 3S/2P on each charge controller? ... With the lower kilowatt hour rating for the battery, it seems like the first set of would make sense. It would allow me to maximize the voltage with the last line loss. Let me know what you think and perhaps I can call you. I was wondering if 149.6 pushes a dangerously close to the 150 volts or do I just cover it up before I actually connected and then put it out in the morning?

[@kevinholland4156]

Jason, how many amps is your 12 to 24 buck inverter? I think I would like one.

[@Jasonoid]

It's rated for 20 amps 👍😁

[@coreyhealth8523]

Had to send my mega 2 back after 2 weeks of using it. The software would hang on the off screen animation so the only way around it was to use a dc input to wake the machine back up. Plus it started showing a battery cell was not in the correct voltage error. so I sent it back do you recommend the pecron e2000lfp or a refurbished mega 3

[@Jasonoid]

I actually had that same issue with the first preproduction model of my Mega 2. They said the problem was fixed and I didn't see it on my second unit for my video! The Pecron E2000 is an excellent price and seems to be more reliable brand. They should be releasing the E3600 soon which should compete with the Mega 3!

[@MattLesak]

I was curious if you could charge the battery and the mega pack separately via solar. I looked it up in the manual and you can do it. The battery pack has its own MPPT charge controller and they state in the manual that it can be charged separately while connected. That’s 2100W per battery if that’s the case. That’s a big differentiator if it actually works as they claim.

[@MattLesak]

BTW, nice capture of the UPS delay.

[@Jasonoid]

Thanks :)

[@Jasonoid]

I didn't have an expansion battery to test with but if it did support that much solar, that would be AWESOME!

[@acekingd8384]

Which one does it prioritize AC charging or Solar charging?

[@Jasonoid]

It will max out both inputs for a massive amount of wattage. So with both connected it allows charging from both AC and DC. There isn't a way to control just solar input.

[@AAa-qd8hb]

Power Station Unit must be able to run gas fired central heat systems without shutting down without the required cool down cycle for preventing damaging the heat exchanger.

[@Jasonoid]

My gas central furnace pulls 800w while running the blower motor, this unit can do that easily.

[@kenimhof9333]

Does this generator support AC passthrough without running the inverter?

[@Jasonoid]

The inverter needs to be enabled for AC output. It will charge with the inverter enabled or disabled.

[@Tactical-hg7ov]

Nice device but for the price you're paying for it , you cpuld get a pecron e2000lpf and 2 expansion batteries with 8000 watt hours. Idk about apps. Im into power .

[@markhager8321]

Do you recommend this unit over EcoFlow Delta?

[@Jasonoid]

The Delta Pro?

[@user-mw9yh4cu2i]

Would you go with this or the EcoFlow 3600?

[@Jasonoid]

From all the power station testing that I have done on the channel, the saying "you get what you pay for" definitely stands true. If you want a more refined, higher quality product purchase the Delta Pro. If you don't mind slight imperfections and a few quirks the Oupes Mega 3 will work fine.
