The product is working very well with quality built. I fully charged the unit and plugged in a box fan and let it ran all night the first day I got it. I like how the LCD displays the watts usage. I also saw in the specifications that the Bluetti uses the LG lithium-ion batteries. Based on my experience dealing with batteries, LG lithium-ion batteries are quite good in general. Since the manufacturer uses good quality batteries, I hope that the rest of the crucial components such as the charge controller, BMS, and inverter, etc. would be in the same high quality.I intend to use this generator as my backup power source. So did a small experiment by connecting a few appliances that I would use on a daily basis to the unit. These are a laptop, and a desk top computer with an external monitor, a modem, and an LED desk lamp. The A/C wattage showed about 113 to 148. Both computers were set to turn off monitors in three minutes and go to sleep in five minutes. I was connecting to the generator all day. I used the computers like I usually do (on and off) and by the end of the day, the battery bar still show 4 bars (out of five) . At this rate and based on my usage, this unit should be able to supply the power for me for the next few days.I really like this generator so far. However, I found a few minor things that I'd like to mention;1] The 42 volt-A/C charger (that accompanied the product) got really hot when I plugged into the unit and started charging. I measured the surface temperature of the charger with a thermometer and it showed 117° F. I don't think that was supposed to be normal. When I noticed that it started to get very hot (almost to the point that I couldn't touch it), I reoriented the charger by standing it up on its side (so the heat can dissipate faster). I also inserted a rack that I borrowed from my toaster oven and raise the charger about an inch from the table (hence increasing air flow). This seemed to work because after a few minutes, I could touch the charging unit again without burning my hand. With that arrangements (the ambient temperature was 69° F at the time), I was able to complete the charge which took about 4 hours (the charger light turned from red to green and the fan on the unit turned off). The charger cooled down after the charging was done. I was surprised because I thought it was going to take at least 8 hours with that 160-watt charger to fully charge the unit. It appeared that the unit had some charge in them which should be fine.Looking back...I should have stopped charging the unit the very minute that I noticed that kind of excessive heat on the charger and contact the seller. I've contacted the seller (who called herself "cimy") this morning and I will update this post later once I heard from the seller.I will try charging the unit with a 300 watt, 24 volt, with 9.78 amp solar panel (within the input specifications) later. I will update this comment.(10/27/2019 - Today, I charged this unit with a 24 volt, 300 watt solar panel (Renogy). The unit showed that it took in between 180-260 watts. The charging was successful without any issue.)2] There is no dust cap for the 12 Volt cigarette lighter socket. It would be nice to protect this outlet from dust and other stuffs while not in use. Fortunately, the diameter of the socket is 2.2 centimeters and I should be able to get it easily either on Amazon or from most auto parts shops (I didn't have a caliper lying around so I used my daughter's ruler...I could be off by a millimeter or so)...... The rest of the comments have to do with the user manual....3] The manual could use some revision. For example, the LCD display for A/C output power is also used for displaying the inverter frequency (either 50Hz or 60Hz) and not just only displaying the wattage for the A/C output. I am mentioning this issue is because of the next item.4] I could not check (or change) the frequency while the unit was still connected to the A/C charger. In order to check and/or change the frequency, you must unplug the A/C charger from unit. The manual does not specifically tell you this. It took me a while to figure this out. By the way, the unit that I got had already been set at 60 Hz so I didn't have to do anything further.5] A picture showing what the screen should look like when selecting frequency would be nice.6] There is no warning when charging with solar panel(s). I was fortunate that I usually read the entire manual before operating anything that comes with one. For this particular case, in the specifications section. I found that the maximum power that can be input to the unit is 500W, the maximum current is 10A, and the voltage must be between 16-60 Vdc. Again, a warning, in the right place, would be nice since this kind of user mistake could damage the unit.7] The manual is slightly unclear in terms of long term storage of the unit. If you look at the "Storage and maintenance" page "EN-02" item 3 and 4. These are for storing the product. Both indicate that the product must be fully charged. However, item 3 says that I should charge the product one a month while item 4 tells me to charge it once every 3 months.8] The A/C output, measured at the outlet on the unit, is 110 and not 120 volts as indicated in the product name and description (as of 10/24/2019). However, the labels on the A/C outlets of this product were correct (the labels said 110 volts). I just reported to Amazon so they can correct the product description. I hope they corrected the information on or after today (10/24/2019).Conclusion: I like the product very much (except for the A/C charger). I will give this five stars for now since the unit (after charging) has been working really well and this is the second day. I will see if their customer service can help me with the charger issue. I will update the rating and this comment after that.(10/30/2019 - Got the replacement A/C charger and it worked without any issue. I am very pleased with their customer service. )

I did a lot of research over the fall and winter regarding solar systems. I was pretty much set on building a system for a cargo trailer I customized to be a mini toyhauler for my Harley. I love to camp and ride so when I started the customization I knew I wanted to have solar power so I could camp where I wanted to. After hours/days/weeks of research I came across a Youtube video where the Bluetti was put to the test and I was seriously impressed. It wasn't a video produced or paid for by Maxoak, it was an independent review. When I looked at the cost of building my own system vs purchasing the Bluetti I decided to go this route. So far I've been very impressed with the construction of the unit and it's performance. I had an issue with the solar charging cord and after contacting the seller a new cord was sent immediately and it works perfectly.There are some pros and cons of the unit. I'll start with the pros. It is compact and self contained. The fact that it has a built in MPPT controller is vital which means you can't over charge it. It also protects the unit from taking on either over voltage or wattage input. The led based charging panel on the front of the unit is extremely helpful. It shows the input from your solar panels in real time. It also allows you to see the output from both AC and DC connections in real time. The only thing I'd rather see; instead of a batter icon that just shows a battery charging, I'd rather see % charged as it goes. There are two 110 outlets on the rear of the unit. It has a typical cigarette type plug for 12v powered items as well. The 4 USB ports on the front are nice but you can buy a wall outlet that has them built in now so I doubt I'll use that option to much, if ever. It is a little on the heavy side but it comes with a very sturdy carrying handle and really isn't that bad. The ability to use this unit virtually anywhere you need power is a major plus. It is also a major plus for it to be charged by either house current or solar power. This unit can be moved to where you need or want power, away from its charging source without a hitch.Cons: I'm not so sure I'd consider this a true "con" but it has a 3000w converter vs 3500w. In my research it seems like 3500w is the more preferred level of inverters. This is a true con in my eyes. It can't be expanded for additional power storage. The other potential con is charging time. It takes 8-10 hours to charge the battery from a 110 source. So if you are camping and run into a stretch of cloudy or rainy weather that last a couple of days you need to be prepared. Another potential con is the fact the maximum power input is limited to 60v and 10 amps. I learned this the hard way. I put 4 Rich Solar Panels together in both a series and in parallel and neither set up worked. You need to pay attention to the volts and amps your panels produce. My 100w Rich Solar panels produce 18.5 volts and 5.41 amps. Doing the math showed that I maxed out the allowable volts and amps using 4 panels. I can only use 3. Here's a shout out to Rich Solar. It is a fully overcast day as I'm writing this and it is 8:30 in the morning. According to my Bluetti those panels, in parallel, are producing 31w of power and is charging my unit.Use...I live in Maine and we are in the mist of the Covid19 shutdown so I have not been able to put the unit to the test in a camping environment. However I have used it during a power outage that lasted over 8 hours. I ran my computer, TV, home wireless systems without a hitch. After about 8 hours of continuous use with those items the battery showed approximately 50% charge. However this is a guess because there isn't a % gauge, it's a battery icon with horizontal bars to show the level of power remaining. I will try to give an update on use once I get out into an environment where I can test it with my toyhauler.In my toyhauler I am using this unit to power a 110v fridge with freezer (medium sized dorm style), TV, interior 12v lighting, exterior 12v lighting, computer and misc battery charging. These are all the things a typical camper would have. I do not have an air conditioner but do have a 110v fan and have used that fan when the temps are higher at night and I need some air movement.Long and short of things: I'm a DIYer and was fully prepared to build my own system prior to finding this product. I would have easily spent the cost of this unit on all the parts and pieces of a DIY build. Yes I could have built a system that allowed for expansion and a battery bank. However I couldn't pick that system up and take it in the house to power things during a power outage. It would be great if Bluetti developed a way to expand the system to include additional power storage and add a larger inverter. Then you really do have a game changer for solar power. But as it is....I don't think you can go wrong.

Like:The promise.1. It's a lot of bang for the buck.I don't want to be the guy playing with fusing, sizing the inverter, picking a controller, decided on which battery (oh, I like lithium but it's expensive unless I built it myself [yuck, no thank you]), voltage converters (12 volt, 5 volt), cooling, cold temperature protection, over heating protection, sizing the wire and whatever else I may have missed.Not my thing. I'm in my RV to find the weather I like, not to become the next PG&E and burn our RV down.2. It's compactThe solar geeks (I'm a retired Database Administer so entitled to use the term since I are(sic) one). have stuff on the walls and wires running hither and yawn (Freudian slip there) and I just don't want to bother.3. The four 5 volt 3 amp usb outlets.Work great. I'd like to say more because I really like how fast they can charge our devices but I'm afraid there is no better compliment for something like this than that it works! The single USB-C hasn't been needed yet. If we use it. I'll drop in an update after trying it for a while.How's the promise working out for us?It started out fine, although I think it's time manufacturers moved their 12 appliances from the ages old 12 volt cigarette lighter connection which so easily can get knocked loose. I'm sure there are others who can add even more reasons to diss that connection.But the 12 volt plug is what we had for the Alpicool 20 we use as a freezer so . . .Dislike:The 12 volt outlet is a pain in the tuchus.It had been giving me the 23 error code frequently since we got it but it was enough for months to stop and restart the 12 volt circuit. Hey, even I can push a button but I shouldn't have to do even that. It should just work, right?23 code = "Over-power protection restart the machine. (system)"Solution = "Check if the total output power is overloaded. Restart the machine.Today, I had to fall back on the manual and power the whole system down instead of just cycle the DC.Was the system overloaded?350 watts solar going in.33 watts on DC for the freezer going out.150-160 watts going to the ice machine through the inverter.It's in an air conditioned room right now because we're at home getting ready to hit the road unless the virus get all Covid on my butt.Is that overloaded? Better not be!If so, they'd better rethink something in the design. Room temperature is much harder to manage on the road unless we're hooked to shore power. In which case, the Bluetti would only be a backup anyway.But we boondock too and this thing has got to be solid.i want to be fair here. I kicked this to Maxoak support before rereading the manual and seeing again [I should have remembered, BUT I'm old so you have to make allowances] that the final step they suggest is powering the entire system completely down. That 'fixed' it.But it shouldn't be happening at all.So there it is that. Now, it remains to seen about Maxoak customer support. I'll straighten out with them the powering down sequence that I failed to try this one time my other method didn't work but this needs to be more dependable. I'd really like to be able to leave the RV for a day and know I won't be coming home to thawed out soggy blueberries for my smoothie.So far, they have been fair. I noticed as soon I I tried charging the ES150 on AC at home immediately after I got it that the transformer got too hot to touch. I know converting/inverting/transforming is inefficient and heat is to expected but it seemed excessive. They sent me a new unit no questions asked.Well, there was a gentle hint that I was a total amateur who didn't understand that a certain amount of heat was to be expected. The total amateur part wasn't too far off but I was experimenting with electricity enough when I was 10 years old to know of circuitry and power loss given off as heat. Bottom line, the newer AC charging unit is cooler running.We need this unit!I can just hear the other side saying 'See, if you had built it yourself, you'd just replace the 12 volt whatchaconvertrabulatingthingabob and you'd be set . . . IF you had only assembled the pieces yourself! If i just admit now that you guys are always right about everything, can I continue to write this thing for the rest of us?No? Didn't think so.Ambivalence.The regulated power is great to have but they need to bump up the voltage. Some devices say they're 12 volt but like seeing at least 13.All it all, I want these guys to make it and continue to make life miserable for all the others who are making excessive profit because we have no choice but to take what they give us.Maxoak is changing that. Yay. Maxoak!

The short:This is easily one of the best purchases I've ever made on Amazon. The Bluetti is a quality product at a great value and, most importantly, the company has earned my trust.The long:I bought the Bluetti because two YouTube reviewers I trust gave it good reviews (check "DIY Solar with Will Prowse" and "Hobotech" if you want to see their reviews). The unit has some quirks and it's missing some features from their wish lists, but it passed their strict testing. It did what the company claims while also seeming to deliver on quality and value.I decided to take the plunge. Within a day after I placed the order, I received an email from a customer service representative checking to make sure I was aware of the capabilities of the product and that I wasn't planning to use the product for applications that exceeded those capabilities. We exchanged a few emails about my power usage expectations and the representative processed the order for delivery.Mainly, they just wanted to make sure I wasn't expecting to run any large appliances or too many smaller appliances at once which would exceed the capability of the inverter. I had, of course, done my due diligence, but it impressed me that they took the time to make sure the customer knew what they were getting and would be satisfied before shipping the product. This simple step likely saves the company and less savvy/informed customers a lot of time, money, and heart break.When I received the unit, we were about a month into the Covid lock downs. To my dismay, I realized the company had failed to include the MC4 solar cable and AC adapter/charger in the product box. I was immediately worried since this is a relatively new and unknown company. I hadn't recorded the unboxing either so it's not like I could prove I didn't receive the items.I emailed the customer service representative from before. They apologized for the failure and arranged to have the missing accessories shipped to me. The shipment had to be delayed for an extended period due to the ongoing disruption of the Covid crisis (non-critical items had to wait in queue; absolutely not the company's fault). To make up for this extended delay, and without me even asking (or expecting it), the representative expedited the shipping so the items would get to me as soon as possible once they were allowed to ship.Since receiving the items, I've put everything to work. The MC4 connector appears to have excellent build quality and works as expected with the Bluetti and my Renogy solar panel. Likewise, the AC adapter is solidly built and works great with my 300w Bestek pure sine wave inverter (for charging from the DC cigarette plug when driving).The Bluetti itself is no less impressive. It's solidly built and handles everything I expected it to. I have absolute confidence in the handle, even in the long term (it's rock solid). I'm able to run my 5 cup, 650w coffee maker on it no problem. Naturally, it can also run my less demanding items as well (small refrigerator, cell phones, high end gaming laptop, etc).Lest I forget to mention it, the customer service representative gave me a courtesy follow up to make sure I had received everything, that everything was working as expected, and that I was satisfied (you're darn right I am).Overall, the Bluetti has met all of the expectations I had based on the YouTube reviews I watched and the advertised specifications. Much more importantly, however I am thoroughly impressed by the company. Their representative was always incredibly quick to respond, helpful, and exceeded all of my expectations. I absolutely recommend this company and will not hesitate to buy from them again in the future should I need anything else.

I got my EB150 a week ago and I've been testing it. So far it works great.I've slept with it charging my Philips Dreamstation (without humidifier) for 7 nights, plus a few naps. Also, I've charged my Samsung tablet twice. It's hard to tell with a 5-segment battery indicator, but I think it was down to around 50%.The average draw with the CPAP is 12 watts. The tablet ran at about 17 W. A back of the envelope calculation makes that 788 watts total, a tad over 50%. So that confirms my guess that it was down about halfway. This is pretty good. Plenty left for phones, a small fan, etc.We live in Hurricane country, so having electric power backup is very comforting. In our small townhome, even one of those little Honda generators (which are awesome) wouldn't work. There's no place I'd want to keep it, plus a gasoline can. The Bluetti can be kept anywhere..When severe weather threatens, I can keep the EB150 plugged in to shore power, and keep the CPAP plugged into it. Kind of like an uninterrupted power supply. It can be charged while in use, so what I'm suggesting is possible. (Some batteries, like my Anker Powerhouse, don't have pass-through charging.) it might affect battery longevity to leave it on charge all the time, so I don't recommend this as a standard practice. (See below.)I'm a ham radio operator and I've tested a lot of ways to maintain power for comms etc. in emergency situations. I'm recommending this unit to my friends in the ham community.Some people will point out that there is a limit of 1000 Watts draw on the inverter. You can't run a Skil saw for instance. So be aware of the limitations. For my purposes, this unit meets all my requirements. I don't want to run a microwave with it.The build is very sturdy.Maxoak responded quickly to a question I had.I'd like to thank Maxoak for a superior and well-made product.********* Edited to Add **********After another week of trial runs, here's the latest. I started using it with the CPAP plus humidifier. Every three nights takes it down 2 bars on the battery graphic.. Each bar equals 20%. Once the water in the humidifier warms up, power consumption drops way down. This only takes 5-10 minutes. So I could use it for a week and still have some left over. If we're without power that long, we're bugging out anyway, so I don't need more than that.I put the AC adapter on a smart plug, so it's not charging all the time but I don't have to plug and unplug it all the time. 3 hours on the charger brings it up one bar. Using the timer on the smart plug, I don't have to monitor it. Start the charger and tell the plug to shut off in X hours. Simple. I plan to keep it between 20 and 80% state of charge for optimal longevity. This thing will outlive me. 😉So glad I bought this. Thanks, Maxoak!
