this review is for my Bluetti system; AC200MAX, B230, and PV420 Panel: what really sold me on this system is the ability to expand the power storage, the amount of solar input that can go into it for charging, and the ability to use the system as shore power for an RV via the 30A output (AC200MAX).the quality of their products is very good, and the user interface is easy to navigate. i would like to see the ability to bluetooth into the B230 w/o having to hook it up to the AC200MAX. there are some reviews regarding the PV420's stand being flimsy, which it is. however, it is functional and keeps the weight of the panel down. if they beefed up the mechanism it would no doubt add weight, which is a negative IMO. just deal with the stand and you'll be good to go.regarding customer service; i have had to deal with them on 2 occasions. the first time with a defective PV420, and the second time with a defective B230, (bad luck i guess). on both occasions the issues were eventually resolved with new replacements. a few things to note; Bluetti has a separate customer service wing for Amazon purchases. all communication is by email. you will need to be patient throughout the troubleshooting process, as you will likely need to try different steps and take pictures along the way, as requested by the customer service rep. in both cases, i was assisted by Anson, who was very pleasant to deal with. upon performing logical troubleshooting steps, Anson arranged returns and shipment of new products. FYI, the PV420 had a defective panel in the array, and wouldn't provide adequate solar power for charging, and the B230 appeared to have only half capacity of the 2048WH, as if half of the batteries were defective or not connected properly. in both cases, replacements were sent out and the system now works as expected.overall i'm very happy with this system, and will likely add another B230 and PV420 panel. I also purchased the DC charging enhancer (D050S), which allows max charging for the system, and the ability to charge the B230 as a stand alone, with a solar panel.

I recently purchased the BLUETTI Expansion Battery B230 and it has been a game-changer for my camping trips and outdoor adventures. This battery pack has a massive capacity of 2048Wh and is made from high-quality LiFePO4 cells, which ensures its reliability and durability.One of the best things about this battery pack is that it is compatible with the BLUETTI Power Station AC200MAX, which I also own. With the B230, I can easily expand the capacity of my power station and enjoy extended power backup for my devices and appliances.The B230 is also incredibly easy to use and comes with a clear and informative user manual. It has multiple charging options, including AC, solar, and car charging, which makes it a versatile and convenient power backup solution.The build quality of the B230 is impressive, with a sturdy aluminum alloy shell that can withstand harsh outdoor conditions. It is also lightweight and easy to carry around, thanks to its ergonomic handle.One con of the BLUETTI Expansion Battery B230, 2048Wh LiFePO4 Battery Pack for Power Station AC200MAX is its high price compared to other portable power solutions. Additionally, the large size and weight of the battery pack may make it difficult to transport, especially for outdoor activities. Some users may also find the setup process complicated and time-consuming. Finally, it may not be compatible with all devices or appliances due to its maximum output wattage limit.Overall, I highly recommend the BLUETTI Expansion Battery B230 to anyone in need of a reliable and high-capacity battery pack for their outdoor adventures or emergency backup needs.

I purchased my blue Eddie AC 200 P a few months ago and I wanted to add an external battery so I bought the b230. Earlier in the week I tried on multiple occasions to contact Bluetti regarding information for this purchase about if it connects with cables I need so on and so forth left several messages on the chat no return from them and also when you call them it goes to voice mail and I says you can’t leave a message because all the voice mail boxes are full. Absolutely no support at all from bluetti . I received my external battery but the cable they sent will only work on a AC 200 max, as you can see by the picture the size of the cable and also the input on the generator. It won’t work. Tried calling them again didn’t get any information no one answered my calls or email me back regarding this.Oh I finally found a way to order the cable I needed, at least I hope it’s the cable I need at this point I’m not sure. But they said there is a wait it is on back order and I won’t get it until sometime in mid to late July. I’m using this for off grid camping which I’m doing now and cannot use my very expensive battery. Not happy with bluetti customer service. Extremely frustrating especially when you’re spending thousands of dollars with this company and they give you no support.

Bluetti has no equal! I use this system as the stand alone power system for my RV. Now that I have it, my confidence in avoiding power failure gives me confidence that can't be explained!

I paired it with the main unit to add storage.Quite powerful but too heavy to be portable for me.

Has some nice extra features for being an “add on” battery, but the cabling is just so cumbersome. Why not angle the plugs so you can reasonably stack the units without having a huge wire loop sticking out 10”?Update: Bluetti contacted me to thank me for my observation and assure me that their engineers were addressing this issue. Now that's pretty cool. Add a star for the extra (rare) customer service... then (update 2) subtract all four because that's just lip service, and customer service is simply non-existent.

投稿が、遅くなり済みません。実際、後に購入した拡張バッテリーB230により1階リビング・キッチン・食卓周りにある各電化製品(100V電源機器)及び、USB電源より携帯・タブレット関係の充電をしています。深夜電力で（エアコン以外：200V電源なので別、他だしスポットクーラーは100Vでキッチン内で使用)の充電で十二分に補えました。本体側のファンは、静かだが充電器のファンの音が高いので、改善して下さると助かる。後は、高質力の電化製品が集中しなければとても良い。

I have a 200 max plus two expansion 230 batteries, have problem with expansion batteries shutting off when , tried half dozen times to contact bluetti customer service but it’s non existent, BUYER BE WARE, maybe another brand would be in order for follow up help

Not a big camper, off the grid enthusiasts, solar genius or engineer… just a person who doesn’t love gas generators & loves being prepared:)Did LOTS of research on portable power stations, this one has so much value for the price & hasn’t disappointed. We have purchased 2 other brands as gifts for family members (prior to finding this one) 1 of these as a gift & 1 of these for ourselves. We do have a large gas generator for extreme power outages bc we have a well & need the extra power in order to have water available, but this one is great for normal 4-6 hour Midwest outages or for longer ones if u r on city water.Pros:-The fast charge is AMAZING! It does get a little loud from the fan but who cares, all the other brand units take like 6+ hours to charge, this one is approx 1 HOUR!! In a power outage situation that is game changing, I can recharge in my car (car charger sold separately) & be up & running in no time.- the price is great, especially on sale- the batteries have 2500+ recharges, most power stations in this range are only 500-800- the app (use this to completely turn off unit when not in use so battery stays charged, I read reviews saying it wouldn’t stay charged & im sure it’s bc they didn’t actually turn it off.- ability to run/charge so many things at once (see below for specs on items we’ve used it for)- wireless phone charger (DC charging must b turned on for this to work… lots of reviews said it didn’t work & im sure that’s y)- comes with solar charging cables- lifepo4 battery (doesn’t get hot, reducing fire risk)- can use while charging (a must for solar charging)Cons:- the AC charger is in the packaging underneath the unit, like hiding in the styrofoam. I read lots of reviews that said it didn’t come with one & that’s where it is.- had to buy car charger separate.Things we used it for:-charging phones, laptops, iPads, ryobi 18v batteries, rechargeable AA & AAA batteries, portable power bank-running usb fans, led lamps (AC & USB), tv, mini fridge, 300w heater, electric blanket (both ac & dc), large ryobi fan, inflating aerobed (0% battery used to blow up Queen sz)Things it won’t run:- basically anything over 600w, even though it says 600w, the battery drains fast using 600w. So our 300w heater will run for 1.3 hours. But our 5w lamp will run for 50 hours. It will not run our full sz fridge but ran our mini fridge just fine for many hours. I tried our keurig mini, shut off, but I need to research the “power lift” option in the app more bc I think it will run that. (7/10 update: keurig mini is 1500W so it will not run that type of coffee maker)I did research though, u can easily get coffee makers that will work w/o power lift & 12v coolers to keep ur stuff cold for days that are not much $$, in case u need this for longer periods of time. You can also get a car cigarette lighter electric blanket that will work much longer than the AC plug in kind, basically anything that is DC will run longer than AC powered items.All in all, very happy with this unit. Knowing what u can use it for and what you can’t use it for before buying is important I think. Hopefully my review helps you with that:)4/9/23: update, I purchased a 60w Blavor solar panel for charging (didn’t want to spend hundreds of $$ on a big panel) At 46-48wh I was able to charge my EB3A from 69% to 100% in less than 2 hours. I did not require the Solar adapter BLUETTI provided, the panel came with a direct cord & adapter for the DC input. I’m very pleased with these results :)11/17 update: unit still works great. Used it for off grid cabin, trunk or treat decorations & we’ve loaned to family/friends for power outages. It did run a full apartment size fridge for about 4.5 hours with normal door opening.

I bought the EB3a to test out its functionality and to hopefully use it as backup power for my CPAP in our frequent power outages. It has a 600W sustained load rating and a peak output wattage of 1200W. It will only allow you to hit that peak rating for a split second or two before it reads overload and will shut off so you need to be sure to look at the input needs of each device before you plug them in to ensure compatibility. I have had this unit for about a month and have used it off and on almost daily, testing things that would work and may not work. This has yielded some interesting results. But before I get into that I wanted to give you a brief list of my credentials so that you have some idea as to my background. I was an electronics technician in the navy for 20 years before retiring and have hundreds of hours of experience working on small electronics as well as large equipment with very high voltage requirements. I have been involved in testing and certification of new equipment for the US military and have spent time as a shift test engineer. That said there are several video’s out there that discuss the efficiency and the capacity of the EB3A so I wont bore you with those types of details. Honestly what do you need to know?? What can it do… What can I use it for….. Is it worth the asking price… Am I going to get value out of it….First question what can it do and what can you use it for.. These are VERY open-ended questions because the reality is that anything that fits inside its power output range it can power. Some of the sicario’s that I have put it through were things like. Charging a laptop, charging two iPad Pro’s and 2 iPhone 12 Max’s. Will it overheat or shut down if I charge multiple tablets and how about a hair dryer? Can it power that? Well, the answer is yes maybe…. Depends on the brand and rating of the hair dryer. I was able to get it to run on low and with low heat if I pulsed the heat on and off. This may seem odd but to the right group of people this info could be very useful, take my wife for example… Also I was able to charge and use my electronic tooth brush with Water pick. All functions worked with no difference between using it plugged in to normal house power and plugged in to the EB3A. In fact the only time I really ran in to any issues was when I tried to run my coffee pot on it. Every time the heating element came on the EB3A would shut down with an overload condition, to be honest this was expected as the coffee pot has a 1300w rating which GREATLY exceeds the 600w rating of the unit itself. It also powered an ultrasonic sink both heating and pulsing its ultra-sonic waves with no issue. The last thing I tried was a house box fan. This surprised me the most of all the tests I did. The box fan ran for 6 hours on low. I charged it up and it ran for almost 4hours on high. Now don’t take these numbers as some kind of promise that it will power your fan for that long but hey, I was impressed. This little unit has some guts! It weighs in at 10.2lbs so its not something that you would want to take hiking into the wilderness BUT day camping or car camping I would throw this in the bag with no hesitations. I did run my CPAP off this and was able to get 10.5hours out of it with the heater off and running it off the AC inverter. That really surprised me that I could get even 1 night's sleep on it.Is it worth the asking price… When looking at battery-powered devices the quality of the battery is the whole price tag and its what makes a good device good and a bad one well bad! You wouldn’t think twice about paying top dollar for a big top-of-the-line truck or muscle car but you would be mad if someone tried to sell you a ford pinto for $50K. The same applies to things like a solar generators. If the maker puts cheap 18650 cells in it at a standard market price and they start to fail after only a handful of uses then where is the value, but if they put LiPO or even better LiFePO batteries and ask just above the standard market price you can expect years of reliable use and there for the additional money now makes more sense and brings added value to your purchase. I have charged and discharged this unit nearly daily and sometimes 4 or 5 times in a single day just to put it through its paces and using the box fan as my constant I still get 6 hours on low even after more than 60 cycles of the battery from full charge to full discharge. Why is this important? Well.. Battery cells can often be a place where companies will try to cut corners to reduce the cost of a unit to make it more appealing to the general public. Back in 2019 I was in the market for a CPAP battery but didn’t want to pay the premium price tag that medical-grade equipment has. I ordered multiple Solar generators to power my CPAP and even tried car jump battery pack that had a built-in dc-ac converter. None of these worked for more than in some cases a few hours in others I could get 1-night sleep on them but they would require hours in some cases all day to recharge and after several charge-discharge cycles I started to notice that most of them wouldn’t hold that same level of charge for very long where I might have been able to get a full night to sleep now I was only getting 6-7 hours and while this is not terrible at some point its just not useful. I finally found a unit that would hold a charge and would give me multiple nights of sleep. But that is for another review. I have now slept on the EB3A for 3 separate nights two nights as a stand-alone power source and one night with it in UPS mode. During the two nights that I spent using it as an external power source, I slept for roughly 9.5 hours and woke up to the EB3A still having 15-20% charge. Anyone that knows or has worked with battery-powered units will tell you that the last ~25% is always iffy and should be treated as suspect because most battery-powered units are really only guessing at the percentage remaining that said you should always assume that a battery at 25% or below is in need of charged and should not be relied upon for continued use. But to have even close to 25% left in a battery pack that is converting the DC power into AC and then the unit to convert it back to DC that's darn good. Honestly, the only way to make this better would be for Bluetti to add a 24vDC outlet onto the unit directly and while powering a CPAP isn’t the primary mission of this solar generator I feel for such a small and compact unit this does a wonderful job. And truthfully I expected it to be dead after 9 hours, so this is a pleasant surprise, please note: my Cpap settings are a little higher than most because im a bigger dude I run about 12 to 15 on the pressure settings, a lower setting like 6 could possibly yield you close to 2 nights on your CPAP with the heater disabled. The charge time from 0% to fully charged is not far from the manufacturer's stated times. In Eco mode with silent charging, it averaged 1 hour and 20 ish minutes to a full charge. This can be hastened by turning on the fast-charging mode but beware that this causes a lot of excess heat and will shorten the life of the batteries. I did use Fast-Charging once to see what the difference in charging was. In silent, it charges at roughly 111w in Fast-Charge it ramps up to 456W. While the difference is huge, I would tend to guess that by using this mode you are most likely to only get ½ of the rated cycles out of the battery pack. It is always best to charge a battery at the lowest charge setting to reduce the amount of heat that the cells experience. That said there are times when a more vigorous charge may be warranted. But I’ll leave that discussion to another time. The cost of this unit at the time of recording is roughly $300 that said compared to many other models on the market some that I have reviewed in the past or have sent back and refused to review. This unit has features that many lack such as wireless charging and voltage conditioning on the DC side of the unit. The voltage is very stable both in DC and on the AC side this means that sensitive electronics won’t be negatively affected by the voltage drop of the battery or battery bounce back which happens when a load is applied and then disappears. Most of the solar generators on the market are made with LiPO batteries and not even name-brand cells the LiFePO4 batteries in the bluetti should last over 2000 cycles which when compared to the LiPO life of 200-250 cycles means you are getting a LOT MORE for your money.All that said what are some things that I didn’t like? First off the fan (in silent mode)… The fan is a variable voltage/speed fan and when it first ramps up during charging it makes a highish pitched noise that when you first hear it makes you wonder if it's going to blow up. Don’t worry once it's up to speed the noise goes away and all you can hear is the standard noise that most small fans make. That said its very quiet and can’t be heard from across the room. Second the max load… This is a tough one because really I think 600W is great for a smaller lighter unit it can power a LARGE range of things without much hassle and the trade-off of a 700 or 800w ac inverter would be that you would end up needing a bigger battery to afford the higher ac wattage. 3rd The screen…. I really wish that it would stay on longer. Or give you the option to see the time remaining in the app. It’s a small thing but sometimes when you plug something in you want to see how the unit is handling it and what to expect from the battery as far as how long it will last…. And well you have to keep hitting the button to see the estimated time remaining and battery draw. Lastly The app I LOVE the app it has SOOOooooooo much potential. Please Bluetti adds more functionality to the app. There is much that a web-based app can provide such as a number of discharge/charge cycles, battery health and more accurate/averaged discharge rate and battery time remaining, this is great for loads that change constantly like a CPAP…Final Thoughts:This is one of those things that if you have never had one before you wonder what you did before you had it. In testing, I plugged in as many devices as I possibly could and as long as I kept it below the max 600w it handled it all beautifully. I am impressed with the fit and finish of this unit none of the buttons feel like they are cheap the plastic is well made the handle is very secure. Overall I feel like it is well built and well worth the asking price. With today's technology and the need to have a device charger close at hand, this is a great option for daily use as well it will prepare you for power outages and even a great power source to take on the road. This is best for 1-2 people and if you intend to use it for a larger family I would recommend looking into the larger EB50 or 70s models. There definitely seems to be a correlation between price and quality when you compare the Bluetti EB3a to other comparable brands. I will be uploading a video soon with much more information. Please don't hesitate to contact me if you have questions about the unit.UPDATE: 08/30/2022Have been using the EB3a now daily since we received the unit. Still love having it around. I recently received the Solar Charge Cable for the unit and have tried charging it a couple of times with the 2 100W panels that I have on top of my shed, it is for sure slower than charging it via 120vac wall power that's too be expected but the versatility is AMAZING. I will be using this in our RV when we are able to take it out. I was concerned about using my panels with no charge controller as it was going to be a hassle to wire in the charge controller in its current location. After reaching out to Sarah and Cimy they assured me that a charge controller was not necessary and that the open voltage must be between 12 and 28vdc and it must not exceed 28vdc open voltage. After checking my panels they were well within spec 15.8vdc so I plugged them in and away it went charging like a champ. I have to say that I am even more impressed with this unit than I was initially. Thank You to Sarah who worked with me to get the solar charge cable she was very quick to respond and very professional she is a great asset to the Bluetti organization. Also to Cimy who has assisted me with many random questions that I have had. They are both great assets to this company and a pleasure for someone like me to work with.

I have tested the unit for about 1 week now. Charged the regular stuff like phones, tablets and laptops... that works perfectly! I also tested charging with 120w solar panels. It's winter here, but I got about 5 hours of sunlight but slightly overcast.I managed to charge about 140wh while using a 48w electric cooler at the same time. Unit charges well . The PV solar imput was about 80Watts. So all good. I have another power station Pecron E600. It's similar in most aspects but this Bluetti EB3 seems better at charging. The supercharging feature is really sweet. The Pecron is really good too. Worth a look too.The only issue that I am not impressed wirh is how much energy the AC output portion pulls in idle mode if left on. There is an on/off switch to activate every part (AC & DC). So you don't use extra watts. But don't forget it on. I left mine on without any load pulling from the unit overnight for about 10 hours. It drained about 55watts. That's about double what my Pecron pulls (30w).

me ha funcionado estupendo, carga mi refrigerador portatil sin broncas

Solar panel works but need 100% direct sunlight to charge. If it gets cloudy, the solar panel will make the unit discharge. But it works.

車中泊で家庭用扇風機を繋いで使用しました。21時ごろから扇風機を使用し、朝方ぐらいまで使えました。商品本体のファンが回る音や、その他の騒音など気にならず快適に過ごせました。SOSライトが付いていますし、災害時にも利用できるのでとても良い商品だと思います。

This device was delivered in good time, from the manufacturer, double boxed. It is solid and strong with all the input/output on the front panel and a flat top with built-in wireless charger. Everything works as advertised, including the UPS a/c function. So far it is working to keep all our battery devices charged for up to a week on a single 100% charge. The only minor issue is the fan that comes on occasionally and sounds like it is stressed as it slowly increases in speed - other youtubers have noted the same issue, but it is more of a surprised than an actual negative. So far, this power station looks like a quality product for a low cost.
