This guy is forcing company's to put out a better product out. I wish we had a few more 100 of these dudes out kicking ass and calling bullshit.

[kateristrobel]

I wish politicians have a least .5% of your honesty. Thank you

[drphibesrises]

Will, there are so many Youtube channels that do "solar and off grid technology" videos. Your knowledge is far superior than ANY of them. It is not just that you know what you are talking about, it is your integrity as a person and your no apologies approach to the subject matter. You call it as you see it. Sponsored or not you are not willing to compromise real world experience or sell out. That says more about you than anything else can. This in turn builds trust for viewers knowing they are getting "honest" information. Other's claim to be unbiased but in reality they have sold out. I commend you for being a good human being. That is SO rare these days. Keep up the excellent work. Your passion is unquestionable. Your integrity is unwavering. I do have one complaint. My wife won't stop telling me how "cute" you are and how nice your eyes are. I can't watch with her. Me, having an ugly mug gets a little butt hurt. LOL. No matter the information you provide is very useful to me so I will always watch your channel. 😂😂😂

[swcomment]

I only bought it for emergencies. So I’m charging it, learning about it and I have it on the shelf with all of my other emergency supplies. I think it would do just fine for what I need it for and it’s probably one of the best I’ve seen to fit my needs. I got the solar panel it’s nice that it’s small enough and folds ups so not much space investment. I’m a 70-year-old single woman so I love that it was so user-friendly.

[MrCPPG]

Other tubers didn't give it the critical eye you did Will. Your thoroughness is appreciated.

[ottodidakt]

Hey Will, professional renewable energy technician and teacher here (Europe) .... Really appreciated your video, you answer all the real questions in a useful manner. Probably the best channel I've seen so far. I will recommend the link to my students. Thanks a lot and keep up the great work !

[PCMenten]

Among the various YouTube reviewers, you are the most credible. You are fair, honest to the point of being blunt, very well informed, and articulate.

Please re-run the round-trip efficiency.

[dunnoyolo]

This is one of the best reviews on this unit! Get a lot of misleading information from Amazon viewers and others. Was really thinking on getting it but not to sure now found it for $999.99 with 110watt solar panel included

[StarboardBow]

Guys and Gals understand. They are going too send it to those youtubers that "CAN NOT" do a deep dive review like Will. Will you did not get it first or earlier because they knew you are totally capable of a REAL prof review. Great job.

[Brokendiode]

Will
Hello, I thought your review of this unit was pretty good, however as one of the other guys mentioned, pushing it to it's limits is not necessarily the best place to get it's efficiency rating, I am a retired Electrical and electronics engineer, and I have to tell you that what you have shown in this video is worst case efficiency.
The other thing that I would like to mention is that when it comes to battery chemistry I absolutely agree with you about Lifp04 as being the Superior battery.
1. They have the longest life expectancy in the industry.
2. They have a nominal cell voltage that makes them a good replacement for lead-acid batteries.
3. They are very stable, not a fire hazard from anything other than a short circuit, which would occurr with any battery type of significant amount of energy storage.
4. And one more thing I like about them is there extremely flat discharge rate, which is one of the reasons that I think most of the people building these portable solar generators are not using them, because you can't use a close scale voltage monitor as a state of charge indicator, for an accurate reading, you have to use a meter that measures the current removed or replaced against time and displayed in amp-hours.
The other reason is that the capacity in amp-hours/kilogram is only a little over half that of lithium Cobalt.
And sense they want to make them as small and light as possible, lithium Cobalt remains the battery of choice.
Now as for this unit not being a good choice for daily use, I have to disagree with you there, unless they are fully discharging and recharging it every day, and at or near the maximum rate.
Remember that that rating on those batteries is based on 100% DOD, so in reality I think that what you would find, is that the battery would probably hold up about as well as any of the other unit's out there under normal usage. Now if you were say using it on a construction site every day to run power saws and other various high current devices, and then taking it back to the office or home and plugging it in so it's ready for the next day, yeah that's probably going to take a toll on the battery but if it is used in a camp trailer or RV and connected to solar panels where it's being charged every day to recover from the night and then mostly floating through the day, I think it would most likely fair as well as any of the other units out there, especially when you consider that the big loads will be a microwave, and even if you use it to make a baked potato, you're only looking at 8 minutes most everything else is between 20 seconds and 3 minutes.
The other hi draw items would be a coffee pot, and maybe a toaster, or an electric griddle.
All short term use high demand items which that 1800 watt inverter won't have any trouble with.
But otherwise a great review.

I have recently dealt with Ecoflow’s Customer Support and I must say I am very impressed with them. I was very critical of them a year ago, but now I think they listened to the criticism and have completely revamped their Customer Support. It is definitely one of the best I have dealt with of any company.

[vanguardvaluist]

When I watch Will doing a review I am reminded of the power of loving what one does in life. This is the key to being exceptional at whatever it is you choose to do. Well done sir!

[breakdownbill]

im not buying a solar generator till Will builds one for us

[xTinBenderX]

Other YouTubers might be bigger, but there isn’t one better when it comes to these kind of things. Great no BS review as always.

[tmise]

As I’ve recently retired, I believe this would work perfectly for my needs. Plan is to build a cargo van into a camper to use a couple of weeks a year at the lake, a couple of family camping trips a year and a cross country trek. Should suit me fine! The fast charging time and six outlets is what sold me!

[peppernation]

This guy is way too smart. I felt like he was talking Chinese half the time because I couldn’t understand half of what he was saying but I trust in his knowledge. Great video!

[bigfootingermany]

IDK Will, for use in a camper van, that is going to have it's own dedicated electrical system, an extra $1000 price tag, for a finicky unit, made by a company with poor customer service seems pretty extreme.
I only ran into your channel 2 days ago, but I've been seriously binge watching your videos. Based on what I've seen so far, I have no doubt you could design and build a better mousetrap than what this unit provides. Even if it wasn't in such a pretty case bin it's R&D configuration. It's really nice seeing a young person these days, with as much intelligence and drive, as you have. Keep up the great work!!

[tammyhalcomb]

I bought this and loved it so much I bought another one on the black Friday sale last year. It says in the instructions that if it goes all the way to zero that it will be limited charge until it reaches a certain point. I can't remember what percentage that is. I don't have my instructions in front of me. But I have been using one of these in my cabin as a back up to my all in one unit if I need it. Boy it works great when I need to microwave or run my blow dryer it works great. I use the other one in my camper and it's fantastic. Also just so you know I credit you for giving me the confidence (56 year old single female) to build my all in one solar system at the cabin. My all in one growatt 3000 has been great. Everything worked the first time I turned it on and has worked flawlessly ever since. It's fun to play around with this kind of stuff. Thanks again for all your help you are an excellent teacher.

[Slimsomerville]

I own one of these, it does a great job. I agree, part time weekend warrior, or emergencies… excellent choice. Runs my microwave, tv, charges phones, iPads, runs lights, coffee maker, induction cook top.. not all at once of course. I am very happy with it. It has its limitations. Perfect for what I need when I need it. Wouldn’t depend on it every day for sure. Charges slow using cigarette lighter, and 200 watt solar panels. But I like if … just know it’s limitations. Thanks for the review. As always.
