BLUETTI EB3A Portable Power Station, 268Wh Solar Generator LiFePO4 Battery Backup w/ 2 600W (1200W Surge) AC Outlets, Recharge from 0-80% in 30 Min., LFP Backup for Outdoor Camping, Trip, Power Outage

This thing has been amazing this summer. I hit up quite a few music events every year (camping at or near venues). This year temps were anywhere between high 80s low 90s. We were looking for something that would allow us to run a full size box fan the majority of the day. I ended up just buying a cheap fan from Dollar General. Turns out it pulled about 70 watts running on high. I was able to take this unit along with a 100 watt solar panel and have a non-stop fan all day long. My 100 watt panel connected with a 20' extension lead was able to put in about 75 watts for the majority of the day. Since you are able to use this as a ups I was able to maintain 99-100% charge on the battery while running the fan all day long. This allowed me to move it into the tent in the evening and power a smaller fan all night long (with a fully charged battery via solar). One day of the trip temps were still high while being very cloudy all day. I was only able to push about 40 watts to the unit that day. We were forced to run the fan on low to allow us to save some battery for the evening. My wife was able to run her hair straightner each morning (something she was not able to do in the past). I have had this unit for a little over a month and I can say it is totally worth it. For longer trips (I was doing 4 day 3 night runs) I would look into something larger but for your typical long weekend this thing is amazing. We have had one power outage since owning this unit as well. I was able to power up my fiber ONT and primary access point for a few hours until power was restored (kept the kids happy). I am slowly finding other uses for this unit. Typically I buy these things and kind of set them aside for their desired use (camping / power outage). This little guy has made his home next to my bed. I like that I can just press a button to power it up and throw my phone on the top (the wireless charging is fantastic). I have not found much use for the built in light (yet) but I am glad it is there. The screen makes this thing so easy to use! I love that I am able to plug a device in to see what its draw is and see just how long I am able to run it (this is a fantastic feature). I love that I can quick charge this guy in about an hour via AC or a couple few hours with my 100 watt panel. I almost wish they offered a version with built in bluetooth speakers vs the led light. I find myself taking this little guy outside with us in the evenings. I set my phone on the top and plug in a small oontz bluetooth speaker. We are able to listen for hours and hours in the evenings (while eating up little to no power). We are taking a family trip to FL in the next few weeks. I have 4 kids all of which are media hungry. I plan on having this in the vehicle with us fully charged so they are able to keep all their tablets / phones charged on the 15 hour drive. We typically set up one of those wireless access points with a media share. This allows them to have access to movies/tv shows off of a hard drive without the need of the internet. I can also see this getting some use on the beach as well. I have to say that so far this thing has exceeded my expectations. After using this with solar and finding out just how capable these types of units can be I may be interested in looking into a much larger version of this for an outbuilding on my property. I would love to see just what it would take to get myself a few panels on the roof. The ability to run some lights and maybe some tunes while out there would be pretty slick.

I've only had this for a few days now but I like it, really nice display, charges fast and lasts quite a while depending on what you're running with it.. and I was happy to see that I got a solar cable with it.. getting that cable juging from the reviews I've read was kinda hit and miss.. but I bought a third party set of solar panels with it and they'll work with it.. My dad who can be an ignorant old man that thinks it's impossible for the power to go out or food run out even liked it.. Me personally I have off grid solar, wind , hydro and generator but this is nice to have in the car with a get home bag or if the grid really goes I can give to my parents to use, hence that's why I bought the solar panels, for them... Again, it's a nice looking unit, light weight, has the best battery and seems really versitile.. the only bad thing I can say about it is the battery of 268 watt hours isn't all that big, I'm sure it'll run led lights all night long but it's not going to run your house. The 600 watt limit is full tilt and may give you a half hour run time which is really good for a small unit like this but be real and have realistic expectations, understand that this is a supplement power source and will not perform and power the things a gas generator or a large solar system will.. but for what it is it's a very impressive power supply that can get you through a short term power outage and can be easily transported.. or to have power out in the middle of nowhere camping or hiking or what have you.. Definitely worth what I paid for it and with a lifepo4 battery should last a long, long time.. 2500 cycles and still carry 80% of it's original rating can not be beat.. there are bigger power supplies but with more capacity comes more weight and room needed... For me and my wants this little thing is perfect..

The EB3A is a handy little machine with plenty of output power! 4.5/5 almost perfect but down .5 the buzzing fan sounds, even on silent charge mode. First let me start by saying that overall this is a great little machine. I admit I may have not bought this at the $299 retail price, but on sale is is most certainly worth it. I wanted a solar generator that had a greater than 300 watt inverter, LiFePo4 batteries, and in a small package. Most importantly be able to power the battery charger for my Stihl electric chainsaw, which draws 300-400 watts. If it could brew a coffee, that would be icing on the cake, but not expected. I did all those things with no issues. It powered the chainsaw charger at 400 watts. It ran my 1200 watt coffee maker at 315 watts using power lift mode taking 5 minutes to brew a cup. 21% of the battery was used brewing that cup. Others have done it more efficiently using different means of heating the water like a 600 watt kettle. I was just testing what I had on hand to make coffee. I didn’t test faster charging as I don’t see the need to put the batteries under that strain. If anything I prefer using the lower speed “silent” option. Which isn’t exactly silent. Some places online say the EB3A will do it silently, but even in the app it states that it will slow the fan and only reduce the noise. Nothing about eliminating it completely. In silent mode the fan will come on occasionally, depending on external temperatures. You can hear the fan controller buzzing noticeably as it slowly ramps up the speed to the fan. It’s not horrible, but certainly not “silent” either. I did reach out to Bluetti about this and they said it is normal. My hope is that they will be able to reduce this via a firmware update. I’d rather have the fan reach its set speed more rapidly, than have to listen to it struggle to move at the lower speed settings as it is ramps up. Still better than the fan being off or full speed only though! The power output meters seem to work reliably for as far as I can tell. Deviations were no more than a few watts from my Kill-A-Watt meter plugged into the grid vs plugged into the battery for the few items I tested. Not counting the coffee maker obviously. For example a 52 watt incandescent bulb registered as 52 watts on grid @ 120 volts using the meter. With the same bulb connected the meter registered 50 watts on the EB3A @ 120 volts, while EB3A registered 56 watts on it’s display. The USB readouts seemed to line up pretty nicely as well. A 4.4 watt load on my USB current meter showed up as 4 watts on the EB3A, a 10 watt load on the USB current meter showed up as 10 watts on the EB3A. There is also some parasitic load if you leave either of the power outputs on, but it does not register on the display. This would be the case if you left any inverter powered on, and not unique to this device. I have also found if you leave the app connected, the processor stays awake, and consumes some battery power. Best to power off from the app or close the app so it will go to sleep sooner. I was wondering why my EB3A was warm when unused at times, and I found the app was still connected each time that occurred. FYI, this isn’t a complaint, just letting you know of some quarks of the device so you don’t have to figure them out on your own. One thing I really like is I can easily boost the battery with some much cheaper LiFePo4 batteries I have laying around. I got 2 12.8V 42Ah batteries for around $80 each on AliExpress with around 1kWh of capacity total. Put in series they will charge the EB3A at about 199 watts, or about 99 watts in parallel. I figured this would work since it is supposed to charge off of a car from the DC input, not just solar, and was rated for enough voltage to put the batteries in series. FYI the batteries I used have an internal BMS for safety to prevent over-discharge and over-current and would recommend the same if you attempt to boost your EB3A with batteries directly. And if using lead acid batteries with no BMS, using a fuse would be a good idea. Also if you buy any 3rd party DC 8mm cables, make sure the plug is long enough to fit in snugly. I had one 3rd party cable where the plug was noticeably shorter than the other and it didn't fit securely into the EB3A. Please check attached pictures to see difference between the Bluetti MC4 cable and a 3rd party cable. I bought the 3rd party cable because it was heavier gauge wire, but that doesn't help if the plug won't stay in. It worked well on solar too getting around 70 watts input on my Dokio 110 watt folding solar panel. TBH I’ve never seen the Dokio put out much more than 70 watts with anything else so I’m not too concerned of any issues with the EB3A. The solar panel was another AliExpress buy. I’ll have to try charging with a better panel in the future. And while many others have done capacity tests I can say this will run a 75 watt incandescent bulb for about 3 hours, or 225Wh of output. Which given efficiency losses in the inverter is not too bad, but not amazing either. Again I didn’t buy this for huge capacity, my extra batteries + solar will keep it topped off. Overall I’m very happy and would recommend this to anybody who needs a small, powerful, versatile solar generator. But just don’t expect it to brew coffee all day (without some backup) just because it can do it a few times on its own. ;)

I’ve had one EB3a since September 2024, and received a second unit Christmas 2024 as a gift. Used everyday, living in my truck and plugged into solar panels. Time for a solid review. The first unit—brand new and has been plugged into a solar panel on my truck every single day since late September 2024. The battery does the job when it’s fully charged, but what I’ve noticed as the months have passed that the unit will always randomly shut off and die at a complete 0% once the charge hits anywhere below 50%-60%, from powering ONE single device using between 2 to 10 watts, sometimes 0 watts when the device is in “sleep” mode. If nothing is plugged into the unit and the battery is still on, you may see the display go down to maybe 40-some percent(Note: nothing is plugged in). On average, when being used with something plugged in, I’ve literally NEVER seen this unit ever display any number below 50% (Again note: with something plugged in) because it always completely dies..straight to an abrupt 0%. This has happened several times now, and yes it has been properly power cycled numerous times. 2nd unit: December 2024, received a second EB3a as a gift. First used, charged, and also set up with solar in my truck as a secondary power source paired with the other. Has been used every single day up until today in early January 2025, when it presented the same exact problem as my other unit. Powering one LED light only using only 2 watts, the battery display shows 70%, and once again abruptly shuts off randomly! Exact same issue as my other EB3a. After experiencing this issue on my first EB3a, I thought maybe it was because it’s somewhat of an “entry-level” unit in the BLUETTI product line, so I really considered purchasing a bigger more powerful unit within the BLUETTI product line. I’m glad I did not, because at this point after experiencing the same issue on my first EB3a and now my recently new EB3a, I’ve decided to sway away from all BLUETTI products moving forward and I encourage everyone reading this review to avoid using their products as well. I also want to point out that when using the BLUETTI app, there is absolutely ZERO security provided to “mask” your unit when connecting on the app using the Bluetooth feature. Numerous times have I selected the Bluetooth option on the app only to see other BLUETTI units as well as my own showing up on my app! I’m then able to select their unit, see their charge and even turn on and turn off their power ports. Not good. There is also a lot of useless garbage filling the main screen of the app. After daily use and experiencing the same exact issue on both units, I’m going to immediately assume the rest of their products are garbage as well. Waste of money. You can’t rely on consistent power with BLUETTI if this is a regular issue that clearly they’re not addressing.

I've been testing this out for over a year, trying it on a variety of appliances. It works for some, not for others. It won't power up our refrigerators, either one. I didn't expect it to, but had to try it. It will power up our propane hot water heater and baseboard heating system. Which is the main reason I purchased it. It is able to run the heating system for about 4 hours during a power outage. This is useful for overnight, so you don't wake up totally freezing. BUT, I also bought it to power up a 30 quart BougeRV portable fridge. See my other review for that. For this works GREAT in that it has a UPS mode, so it charges while supplying power to the fridge. Not all power stations have this feature. It does get hot while charging, but I think that's partially because I'm charging with a AC plug not through the car in my testing so far. This brings me to my main point for writing this. I found that the fridge ran over 2x longer using the DC output than it did using the AC outlet. Yes twice as long or more. It's because the fridge is low power and the DC to AC converter in the power station is not very efficient when supplying a lower wattage (28 watts). It also burns about 12watts just in standby on AC and only 5watts in DC. So, in conclusion, it's a really nice unit and I defer to others who have reviewed it if you want more details on it's operation. I'm only writing this to warn you that low power appliances on AC are much less efficient; if possible, run them on DC. My BougeRV 30Q fridge ran for 22 hours at 34 degrees in about 70 - 80F room.

I live in California and over the last few years I have had to deal with powercuts from earthquakes, weather, fires, etc. I bought this Bluetti portable power station for added peace of mind during these scheduled and unscheduled powercuts. The following features caught my eye on this unit: * Fast AC charging: I completely drained the power supply to 0% and then charged it to 100% in just over an hour. Fast charging is important to me as it means in an extended power outage this unit could be recharged from a generator or a car quickly. * 100w USB-C port: This unit offers a 100W USB C port (instead of a 60W USB C port that most the others do). This is great for charging Laptops quickly (although you do need to use a 100W USB-C cable to get all this power) * The option to connect Solar Panels to the unit and charge it from the sun (I haven't tested this feature yet, but I just really like having this option) The Bluetti E3BA is a very practical and convenient power bank/supply. It delivers up to 268WH of energy/power to your devices. Assuming an 85% efficiency, this is enough energy to recharge a powerhungry 16" Macbook pro (100WH battery) a couple of times, or the smaller Macbook Airs (50WH battery) around 4 times, and the biggest of phones iPhone max battery (~17WH) ~13 times. I tested recharging a 16" Macbook Pro's empty battery (100WH). It used 45% of the E3BAs total charge, which is what I expected. Bigger units with more battery power are available, however with more batteries comes more weight, and these portable generators can get very heavy. This unit is small and light enough to be carried around and moved without having to worry about hurting your back (old person problems!). Its convenient weight and size also makes it easier for casual use, like easily taking it outside to the park, beach or garden. With a 600W maximum draw on the AC side, this unit is *not* suitable for powering electric kettles, portable induction hobs, hairdryers, or anything else that uses lots of power. Even if it were to power devices like this, they would drain the battery very quickly. This device at this size is more suited towards gadgets and laptops rather than power hungry stuff. It also has a nice clean app for checking the current status of the app and for doing firmware updates. The app does not force you to create or sign in with any accounts, which is nice and refreshing these days! Overall I am very happy with the peace of mind this device provides, and I look forward to my next scheduled or unscheduled power cut knowing that I'll be able to keep my laptops, phones and internet hotspots going all day (and then some) with this device.

I work for a tier 1 supplier to automotive companies. This was purchased as a possible power supply/power stabilizer for electronics that goes into our test vehicles. We need a source for clean, and stable DC power to run a small system in our car, and one that flies over voltage dips if the vehicle stops and starts the engine at a stop light. I read quite a few reviews here, and checked some of the reviews on YouTube, and this looks like a good candidate for us. It is surprising that nobody talked about charging the EB3A with DC (like from a car), while feeding "12 volt" DC power to loads. It would seem that this should be expected functionality, and it looks like it is. I tested it with a lab power supply, feeding power into the 8mm DC input while powering an industrial computer from the EB3A "car lighter" DC output measured at 13.4 volts. It's clear that the DC input is an MPPT input, which is typical of a solar charger. My lab power supply maxes out at a 3 amp output, but when I vary the voltage on the supply, the EB3A will allow the voltage to climb. When changing the voltage, the current drops down momentarily, but it always figures out that the 3 amps is the most that it can pull from the supply. So the charging watts will go up and down according to the voltage that I dial in at the power supply. This is what MPPT does - it figures out how to get the most watts out of a DC power source, such as solar panels. Pretty cool!!!!!! I love that I can shut off the DC lab power supply, and the computer connected to the EB3A will continue to run without any interruption, as expected. An AC cord was plugged into the AC input while the lab supply was feeding in DC. It's very impressive to see how it combines input charging power from DC and AC at the same time. While playing with this, I loaded the app onto my Android phone. It was super easy to pair right from the app. Its a very well designed app that displays AC and DC power coming in and also AC and DC power going out, with battery charge level in the center. I was happy to see that the Bluetti app keeps the Android screen active. So if you want a full-time display that doesn't go dark on you, use the phone app, and find a beater phone that you can dedicate for that purpose. Once the EB3A battery was fully charged at 100%, the current draw on the lab supply dropped down to 10 mA. The app showed 0 watts of PV input. The AC input showed 16 watts coming in, equal to what the small AC load was pulling. Finally, I checked the DC output with my scope to see if I could see any major noise on the output. While charging with DC and outputting DC, the DC output is very nice and quiet. But when AC in and AC out is on, the DC lights up with noise if there's no load on the DC. But when I connect the industrial computer to the DC as load, it quiets down quite a bit - maybe the computer power input is filtering out the noise? Anyway, I observed no functional issues with any connected devices indicating any kind of malfunction due to noise in the power supplied by this guy. My only gripe so far is what everybody complains about. The EB3A display always shuts off after a minute or so. I can see doing that if it's running solely on the batteries, but if it's receiving input power to charge, then the display should stay on. Even more irritating is that you press the LED light button to re-activate the display. But if you press that button twice, and are looking at it, you will get blinded by the light. Overall, I am super impressed by this incredible little power system. It is an amazing little bundle of power.

My uses cases were initially as a on the go small charging device for car camping and keeping a 12v rv style refrigerator running. Recently between 12/16/25 to 12/19/25 I used it as an inverter/ups to keep the home refrigerator running. Its now making a buzzing noise while charging and it doesn't hold a charge as well as it used to. I've used this nowhere near the advertised charging cycles. pros: -Inexpensive -worked well initially -light weight and portable -bluetooth integration to control from an app remotely and check on system -multiple different outlets appropriate for car camping or on the go cons: -Failed when I needed it the most -Issues with holding a charge. Sometimes it would go from 50% reported power to 0% -Makes a buzzing noise while charging now -The screne will stop working you can't turn on AC/DC. The only way is through the APP -Received several notifications stating that there was inverter overload but power in/out was never over 500watts
