Bluetti EB70 Portable Power Station Review ⚡
Obviously, a lot of the people that are going to be interested in this are maybe going to be using this for, like things like outdoor camping, obviously off grid type of situations, i’m going to talk about mainly about the way i’ve been using it. In terms of my fpv drones charging up a lot of small batteries, you know batteries like, for example, cameras, small drone batteries, etc. That’S going to be the primary focus for at least my review now. I’Ll talk about all the specs and everything that comes with this particular one. I think the biggest difference on this particular power station is that it comes with a different battery chemistry than some of the other ones you’ve seen out there. This one comes with lithium iron phosphate batteries and the main advantage of that one is going to be more charge cycles, so they’re, claiming up to 3 500 charge cycles up to 80 percent, so compared to a lot of other power stations out there. This will probably have a lot better longevity. Also, the chemistry is more stable, so less chances of battery fire there’s a lot of also important over current protection over voltage protection in the unit itself. So we’ll take a closer look at all of the available inputs and outputs on this particular device, as well as pros and cons and the things that i like, and i don’t like about it. Okay, so in terms of everything you get with the package, you get the power station itself.
You do get an external power supply um that you have for ac charging up the internal battery. You do get a cigarette lighter adapter. So if you want to charge it off your car uh car battery, it’s um, this is cereal adapters, for that takes about seven to eight hours on 12 volts three to four hours on 24 volts depends on the voltage system of your dc battery and your car And then you got your solar panel cables here. These are some mc4 connectors. They do have a 200 watt solar panel that they sell separately, but it’s currently not available. If it comes available later i’ll link it down in the description. Unfortunately, i won’t be able to test that. I think i can show you how this works with the panels. I’Ve got with the eco flow that i got in a previous video that i reviewed a couple weeks back. So looking around the unit itself uh on top here, you have uh, basically a wireless charging pad for, like phones and stuff, i think it’s up to 15 watts. Pretty nice. You got just foldable handle which does make it a little bit more compact and easy to carry it’s a very rugged handle this whole the whole build construction. This is very nice, it doesn’t feel cheap at all. It does feel pretty solid. The screen here is kind of simple, so you have basically wattage on your input and your output, so it shows you what kind of power usage you have.
The battery indicator here is a very simple five level battery indicator from like 20 40, 60, 800 percent, and it does not show you uh individual percentage, which is, i think, uh disadvantage. I think, in my opinion, got a light here. A few different levels of brightness, plus your sos and then last hour, the fourth click – will turn it off. The input here is up to 200 watts max so it’s 12 to 28 volts. I heard it will go up to 30 volts before it shuts off, does have a built in mppt solar charge, controller, so uh it does it’s. I think, with that it’s a little bit more efficient in terms of how it charges off of solar and if you do charge off the solar they’re, saying it’s, also similar to charging off a car battery around 78 hours. If you have the maximum 200 watts of power now, of course, you know solar isn’t going to be up at the maximum all the time, so uh it’s, probably something somewhat less and since it’s 200 watts max. If you want to run panels in serial or parallel, you probably aren’t going to be able to if you want to charge up the internal battery faster on solar, so it looks like 78 hours is going to be your best bet or maximum ability on solar. For this particular power station now moving on to the dc output section here and turn this on, so this little button turns on the screen the screen times that, after about a minute to save battery, you have two 100 watt, usbc type connectors here: power, delivery, 3.
0. So you can power up and charge a pretty modern laptops that will charge off usb c up to 100 watts. So things like macbook airs, Music, lighter, you know, windows laptops will up 200 watts will charge off of the usbc and of course, you can charge up a lot of other things off of the usbc as well: two old style, five volt, three amp usb a ports. Here you have your uh 12 volt, 10 amp uh, 55 21 barrel connector ports here. So if you have devices that can charge off of a barrel port a barrel connector, you can have these two available. Only up to 10 amps same with the cigarette lighter adapter it’s 12 volts up to 10 amps, so these are limited up to 120 watts the maximum power output on the dc here. So if you want more than 120 watts of power or yeah, if you have more than 120 watts of power, you’re gon na have to use the ac side, which will go up to 700 watts of power. There’S a built in 700 watt inverter inside here. For these four ac outlets, so you have two on top here with the little spacer here for the third prong and then two standard, two two prong ac plugs just powered up turn that on there’s a little light here, it’s not that easily seen it’s, very dim And it’s kind of a white color but uh i wish it was a little bit brighter so it’s hard to tell if it’s, actually on or not the inverter in here is a pure sine wave, inverter, now i’m kind of wondering why they didn’t include the ability To do the internal charging with the uh internal inverter, instead of using an external inverter to charge the batteries uh that’s, how? I think that they would, you would do it with some of the other power stations out there.
The uh ac charger is actually built in and i believe, they’re using the exact same inverter that is actually built into the units it’s a little strange that they’re using a separate external power supply for that maybe they’re trying to save weight. It is um a couple of pounds for that, perhaps maybe that’s. Why? Because maybe you would leave that at home and then you could just plug them in at home when you’re charging it now. The thing about the external ac power, brick is that it is always on when you plug it in so you plug into the wall, turns on and there’s an internal fan, that’s on all the time, it’s very loud, approximately 58 to 60 db, pretty annoying it’s louder Than the fan that’s in inside the power station now, when you’re powering up stuff from the power station and you’re drawing less than 100 watts of power, the internal fan on the power station does not turn on so it’s, completely silent, which is nice after you exceed About 100 watts, it will turn the internal fan on and it’s, not as loud as the external power supply. Brick it’s it’s, quieter, it’s, not as noisy it’s like around 40 48 45 db somewhere in there, so it’s not too bad. Now the thing about this inverter here that’s on the ac output section, it is 700 watts max and they’re saying it can burst up to 1400 watts, but i’ve found the um way it works on the um.
Basically, the burst output is a little unusual um for some devices. It doesn’t do anything like it doesn’t work at all. I tried it on a heat gun that will draw about a thousand watts and it wouldn’t even power it up at all um. I know that, like the eco flow that um river river station river river, pro, i think was what’s called the one i reviewed previously. It would actually do a little trick where it would uh allow the amperage to remain high but reduce the voltage to basically keep it within the the range of the inverter. But this one doesn’t seem to do that, so you you’re what you’re going to be using this for is going to be kind of hit and miss some of the higher than 700 watt devices will work and some of them may not work. So, generally speaking, i would only recommend this, i think, for someone that’s going to be using this on lower power usage, so nothing like microwave or like a stove like electric stove, anything that’s going to be drawing a lot of power like way over 700 watts. I wouldn’t recommend this at all, but for me, for my purposes it seems fine if you’re gon na be charging a lot of smaller devices, uh it’s, totally fine uh. You know if you’re drawing less than 700 watts. This device will work great for you now considering the efficiency of the conversion here.
So basically, the internal battery here is 716 watt hours that’s. Why it’s fully charged capacity is with what it’s rated for now? I found that, depending upon what you’re charging up so, if you’re charging up a lot of really small batteries, for example, the efficiency conversion is a little bit lower versus say if you’re just doing like um. If you just want to test the efficiency of the internal components of this particular power station, if you’re just testing that on the bench in the laboratory setting you’re, probably going to get about 85 to 90 efficiency in terms of the amount of energy, you can extract Out of this power station out of the 716 watt hours, but if you’re charging up a lot of smaller batteries, obviously you’re limited by not only the efficiency of the components inside this power station, but also the other devices that are charging there’s always going to be. Some amount of losses whenever you’re charging other when you’re, basically charging batteries from other batteries and it’s no different in this case so i’m. Finding that when i’m charging a lot of smaller batteries on this one i’m getting roughly 75 to 80 percent efficiency. In terms of what i’m able to extract out of this power station, which is not surprising at all, i mean that’s actually better than expected uh. But if you’re charging like say larger fewer batteries with larger batteries, then i think you’re going to find that it’s going to be a little bit more efficient.
Now, for you guys that are charging up fpv drone batteries uh, i would recommend sticking to the 700 watt ac output here, if you have, if your charger has ac a bit of availability, if you’re charging off of the cigarette lighter adapter here or the barrel, plugs You’Re limited to 120 watts, so if you’re charging up a large 6s battery and drawing like a lot of amps, what you’ll find is the power station will basically cause a fault. You’Ll get a message on the screen here, so you should. You have a short and then the dc output will shut down and then you’ll have to basically turn it off and turn it back on to reset it uh to turn it back, basically to basically turn the power station back on um. So you have to be careful on how you set up your charging, so i got a 6s battery it’s going to be drawing about 25 volts and you know divide that into 120 watts minus some efficiency losses, you’re looking at about a maximum about five amps. If you go above five amps uh, what you’ll find is you’ll, the power station will shut down. It’Ll, draw it’ll be drawing more than 120 watts more than this dc output can handle and you’ll just basically trip the internal short circuit control meter inside here, and it will shut down. So if you want to draw if you’re going to be charging up big batteries at more than 120 watts, you’re going to going to be limited to the ac outputs over here at 700 watts and obviously like, as i mentioned before, if you go above 700 watts You’Re going to probably run into some problems: okay, so now in terms of like the overall weight of the unit it’s about 21.
5 pounds by itself, throw in the external um ac charger, it’s a that’s about two pounds about 23, a little over 23 pounds, total weight To carry around it is definitely heavier than the power stations that are based on lithium ion chemistry, so the lithium ion phosphate. I think that’s, where you know that’s the trade off you’re, going to make so you’re trading off a more stable chemistry for additional weight and also long a long, basically a longer lifetime for the power station. So you’re going to be able to use it for many more years compared to power stations based on the lithium ion battery chemistry. But then the advantages, conversely, is that you’re going to get faster charging like the lithium ion ones and charger charge up faster. But you know the the lifespan of those particular power stations are going to be shorter because you’re, basically stressing out the batteries quicker on those types of chemistries all right. So i am uh plug i plugged in the solar panel that i got from ecoflow. It uses the same mc4 connectors and you can see i’m drawing about 102 watts of input, which is you know, obviously half of the 200 watts max on here – and this is a 160 watt panel. So i’ll just show you here running the cable around the side of the car up here these are the mc4 connectors and then this is the panel up top put on the roof of my car here, because i wanted to get the max.
I guess that basically sun’s almost directly overhead it’s a little bit off center, obviously not exactly directly overhead, and this panel i found is not super efficient, it’s, rated 460 watts and it’s pretty much maximum brightness right now and and i’m only putting in 100 watts. For this panel, so obviously i don’t have the of the blue blue yeti version of their panel. That says suppose it was 200 watts and that’s one that they would recommend for this one. I don’t know if you’re going to get a 200 watts on that one, but at 100 watts it’s half of the 200 watts max so charging this up on solar it’s going to be probably double the time now. I am kind of close to the top of the battery here, so it might be limiting the amount of power coming in because uh, if you’re at the, if you’re in a lower state of charge, it could be that you might get more power inputs. So it could be artificially limiting the amount of input power based on the state of charge of the battery here to protect it, so that i’m not 100 sure as i’m suspecting that’s, probably the case, because i think when i plugged this in on the ecoflow, i Was getting more than 100 watts on full full sunshine? It was like uh, i think when i was testing it was closer to 130. So i think i think that it is actually limiting it based on the state of charge it’s around between 60 and 80.
Here it doesn’t actually show you the exact percentage, it’s kind of unfortunate okay. So what do i like, and what do i like about this power station – the fact that it’s got this lithium iron phosphate battery chemistry does give it a long life span. I would say 30 40 percent, more than ones based off of lithium ion chemistry. The downside is that it does charge up slower and there’s a lot of limitations in terms of power, input and output to protect the batteries. But that gives you a the power station. Will last a lot longer for you, so if that’s more important, then that’s going to be a pro? Some of the cons, in my opinion, are the 120 watt limit here on the dc output. Here on the cigarette lighter. I tend to use this more on the road with my lipo chargers and i mostly charge up small batteries so it’s, not that big of a deal but every once in a while. I want to charge up a large battery and i’m limited to about five amps power jaw, whereas it can go 12 volts and up to 10 amps on here, but if i’m trying to charge up a 6s battery at 25, volts it’s drawing more you know close To 200 watts and that’s going to be too much for this. I do like that. It does have the two 100 watt um usbc power delivery, ports here, so they’re, just one that’s a nice feature and then you do have extra ac plugs here.
You know four, which is quite a few and up to 700 watts. Now, obviously, if i want to charge up bigger lipo batteries, i can use the ac output here on 700 watts, but that just means i have to carry around another, basically an ac to dc power, brick for my lipo charger to access that extra 700 watts, which Is extra equipment i would rather not have to carry around, but apparently, if i only use this one use this particular power station. I’Ll have to do that for this one, so it’s a little bit of a downside for me now this is a fair bit: heavier uh 21 and a half pounds plus the power brick uh closer to 23.5 pounds. So yeah. You know if you’re looking for something, lighter that’s going to be a downside for you uh, but you know that’s that’s, the trade off you get for going with the lithium iron phosphate. Chemistry does come with a two year. Warranty um, i think a lot of other ones only come with a one year warranty. So if you’re looking for something that’s going to have a longer warranty period, then obviously the two year warranty is going to be a pro for you. I don’t like the the screen here: uh it doesn’t, give you individual percentages for the battery and not a lot of information here on terms of input output, obviously it’s very simple and basic, but mostly this not being on here in terms of individual percentages, is a Downside for me the thing that about the the buttons here you know um, if you press it turns the screen on but, for example, on the ac side, it actually turns off the ac, and you can’t see the light.
Turning on enough but i’ll turn on and off over here then uh press it again, and then it turns off these plugs here so uh. I i usually, i think, if you press this, one it’ll actually turn off the power to these plugs. So if you want to see the screen again, i recommend not pressing this one. This will actually power off this section. If you want to see the the screen again, you just press the dc button here now if the thing is like it’s currently on, but the light isn’t very bright, so uh it’s hard to tell that it’s actually on. You have to look at very, very clear closely and it’s actually drawing power right now, so you might leave it on inadvertently and i don’t believe it has a timeout feature where it’ll actually shut off, so you have to actually press and hold, and then this light Should go off here, yeah, so now it’s actually off so we can tell is uh. If you press the button, the screen will turn off much quicker. You can see that that that means it’s actually off if it stays on. Obviously the screen stays on and the power station is powered on anyway, that’s gon na do it for this video um. Hopefully this will help you guys out in terms of making a decision whether this is the right power station for you or not.
