The BLUETTI EB3A Portable Power Station is a must-have for anyone who needs reliable power on the go. I’ve used it for outdoor events, small worship gatherings, and even emergencies, and it’s always been a lifesaver.First off, it’s super compact and lightweight. You can easily carry it around, and it’s perfect for outdoor use or quick setups. Even though it’s small, it has a 268Wh capacity, which is enough to charge your phone, laptop, or even run LED lights or fans for hours.The best part is that it has a bunch of different output options. You can use USB-A, USB-C, AC outlets, and even a wireless charging pad. So, you can use it with anything you need. The LCD display is clear and easy to read, so you can always see how much power you have left.One of the coolest things about it is how fast it charges. You can charge it using AC or solar panels, and it charges really quickly. The built-in MPPT technology also makes sure that it charges efficiently from the sun, which is great for people who are eco-friendly.Overall, the BLUETTI EB3A is a great portable power station. It’s reliable, well-designed, and it’s worth every penny. Whether you’re camping, hosting events, or preparing for power outages, this little powerhouse will be your best friend.

Everything works as described. Quality build and materials, and design. Charges really fast, holds charge “forever”. Quiet and cool operation. Relatively light. Love to know my e gadgets are available whenever I’m off grid.

Buenísimo, pero no incluye el cable para conectar al carro.

中古品と言う事で安く買えました丁度軽くて使いやすいと思いますただカーアダプターがオプションなのでべつに購入しました中古品でも展示品が何かで使用感は無く綺麗でした

After using the BLUETTI EB3A for a couple of weeks, I can confidently say this little power station punches above its weight in terms of versatility and convenience. I initially bought it for weekend camping trips, but it’s quickly become my go-to power backup at home, and I’m really impressed with its performance.The EB3A is compact and easy to carry, which makes it ideal for travel or storing in a small space. Despite its portable size, it packs a solid 268Wh capacity and offers various charging options, including AC outlets, USB ports, and a 12V car outlet. The layout is intuitive, and each port is easy to access—even in the dark with a flashlight, which I had to do on a recent trip. The USB-C port, rated at 100W, was a real bonus because it allowed me to charge my laptop much faster than expected, making it a surprisingly practical work solution on the road.One of my favorite features is the EB3A’s fast charging capability. With dual input, I was able to recharge using both AC power and a solar panel simultaneously, which was a game-changer when I needed power quickly. Even just using AC, the recharge time was impressive, taking about an hour and a half from near empty to full. The solar compatibility also means it’s great for extended trips where outlets aren’t available—ideal for anyone who wants a truly off-grid experience. When charging directly from my SunJack 40W folding solar panel, the unit charged from 85% to 100% in an hour and a half.If there’s one thing to be aware of, it’s that the fan can get a bit noisy when the unit is charging or under heavy load. It wasn’t much of a problem outdoors, but I could see it being a slight annoyance indoors, especially in a quiet room. That said, it’s a minor issue considering how well it works overall.Overall, the BLUETTI EB3A is a well-designed, efficient power station that offers a lot of versatility in a small package. It’s durable, charges quickly, and provides enough power to keep essential devices going through camping trips, road trips, and even the occasional power outage at home. For the price, it’s hard to beat the combination of portability, functionality, and ease of use that this little powerhouse offers. Highly recommended for anyone looking for a reliable portable power solution!

Ok so I tested out the device because there’s a few reviews that had some negative things to say about the features.1) Some say that it was not charging via solar, so I immediately went out side on a partly cloudy day and with a 100watt panel, I was able to get up to 70watts, of course it varies but this device worked amazingly.2) some say that the UPS feature doesn’t switch fast enough, I booted my router and modem up with this, when I unplugged the AC, we did not lose internet, so this did not “blink” like in some reviews. Also, so far it’s going strong in UPS mode without the “blinking”. Note pass through works but you can’t overload the device when plugged in, has to be same load as when using the battery.3) quick charging: using solar I was able to go 75 - 98 in just over an hour / AC charging even faster4) also note that if you charge via DC, you can also pass through with DC connected… basically using solar to charge the unit and any devices plugged into the USB5) just wish there was an option to change the LCD screen to stay on.6) testing out how much it discharges when not in use… will update later.So far VERY good generator, get one if you can find a good deal!————UPDATE—————Ok so this is not a reliable UPS. 2 days in, I had the error inverter overload three times (see screenshot). Each time it powers down until you reset the AC output. This happened 3 times unexpectedly with a small load of 45W (router and modem). I have since unplugged everything from it. Again, I didn’t purchase for the UPS function, it was just nice to have. If you are getting this for the UPS, I would recommend you pass.I would strongly suggest NOT using this for a cPAP set up, this could turn off randomly. The advertising for using this device for cPAP is inviting a huge lawsuit. Bluetti, I hope you can update this with a firmware update!

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.

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. ;)
