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

Bought this off the global auction site. It arrived quickly enough but the battery was totally dead which should have been tye first warning sign. Charged it up from the mains and it produced a bad electrical shorting smell but did charge to 100%. Tested it by running my 50w router and it gave an impressive 250w which is not bad for a 268wh device. However my next test was to charge it from a solar panel. I used a 200w panel which the manual said was the max. It is winter here in the UK so the panel maxed out at 110w, we'll within the specs. The device charged to 90% and then just stopped. At this point the AC input and output ceased to function and the ups and ac lights were flashing. The DC output was still working so it became apparent that yhe inverter had blown BUT was still drawing power. The next day it was totally dead and wouldn't charge. I sent it back for a refund. My advice don't bother, there are better options out there and STOP believing the YouTube reviews.

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..

This BLUETTI EB3A is a great little power unit from a well-known brand in the industry. I have the bluetti AC50S power station and 120w foldable bluetti solar panels from a previous indigogo campaign, and they’ve run great for about 2 years now. This new addition has a smaller battery at 268 Wh than the AC50S (~500 Wh), and to be honest it is quite small, BUT this unit has a bigger 600W inverter (300W on the AC50S). The smaller battery is actually great for carrying around the house, carrying to the beach or picnic spot, etc. The batteries are the heaviest part of these power units, so less battery actually means more portable. This isn’t the unit to backup your fridge or freezer at home for long power outages, for that you want a large and heavy unit that won’t be portable. For this unit, portability is amazing. My girlfriend can’t carry the heavier power units, but this EB3A one she can carry around the house no problem. We had a short power outage and she was able to use this for a light and to keep her phone and laptop charged so she could continue working and keep her phone charged for a wifi hotspot. Also, it’s a pain to carry the big heavy ones for a trip outside such as a picnic or beach day, and so most times I leave them at home. With this unit, it gives me enough power to keep devices charged at the beach or park, run a small fan, provide light, and even run small appliances for short times (bullet mixer smoothy at the picnic!). Take a look at my photos and note that at the BOTTOM of the box under a piece of foam is the power cable. DO NOT THROW THAT OUT. This also came with as solar connector panel.

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

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。

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. ;)
