Yes the firmware is updated on both units. The shipping label that Bluetti send Amazon for me to use to send it back says From:______________________________
TO: BLUETTI POWER INC
6185 S VALLEY VIEW BLVD STE D
LAS VEGAS, NV, 89118-3918
Then the barcode.
When I had my problems with the solar panels arriving broken, Amazon also refused to replace it for me and told me I needed to contact Bluetti directly. So looks like YMMV. That was contacting them within an hour of the package arriving at my door.
If they sent you a shipping label to use, then why are you stating you have to pay for return shipping?
If Bluetti sent you a shipping label, that’s pre-paid, man. All you have to do is pack it up and take it in, they’ve already paid for the shipping. Amazon just wasn’t on top of the details would be my bet. 
EDIT: Looks like Scott beat me to the punch on that one!
Another thing - when I had to return my solar panels, I just snapped a picture of the drop-off receipt the UPS store gave me when I took it in, and they had the new set on the way to me within a day of that, didn’t even have to get back to them first. Easy as pie.
This is not a pre-paid label, UPS will not take it without me paying for the shipping !
Here is a copy of the instructions. See the part I must pay !!
Cut this label and affix to the outside of the return package
Well that’s surprising for sure, I don’t think I’ve ever seen a company send a non-paid return label. That’s super weird.
I agree. Look at the items Bluetti is now selling on Amazon. Nothing about returns if bad. The ad for the EB3a has changed from the time I bought and what Amazon is printing on the Ads.
As I said - reach out to customer service.
But I have never seen a UPS label with a barcode that has not been paid. Are you certain it’s not prepaid?
Enter it into the UPS website and see what it says.
The barcode is just the RMA # not a UPS tracking number. DxW3…RRMA
I suggest you contact the after-sale support email first, It seems they are paying more attention there. GOOD LUCK!
Thank you all, Bluetti connected me after all your help and I can ship all the units back at their expense… Thanks a lot.
The problem with the EB3a is the AC output turns off randomly in the UPS mode. My fix is that if ECO mode is off, the AC output must stay on until the battery goes to zero. That is how a UPS mode works and Bluetti needs to fix their software. I would be glad to buy the EB3a if they fix their software.

When I bought my AC200 I purchased it from Amazon figuring if I had an issue I could just use them for the return but I received a notice that if I needed to return it I would have to go directly through Bluetti. I think I didn’t realize this until I already ordered it otherwise it may have changed my reason to use amazon. Thankfully I haven’t had any issues. I have saved my box this entire time Just in case. I’m sure the day I cut it up and put it in the recycle bin will be the day I need to return my Bluetti.
@hey, Is it in Standard mode? Mine did the same as yours in Silent mode, but has not failed, even when I cut input power, as long as I am in Standard mode with ECO off.
Good question, I tried it in standard and Silent mode. It failed in both modes, it runs my internet switch and other things about 25 to 40 watts varying. The AC output must stay on if the UPS mode is worth anything.
This is the exact same issue I’m experiencing. Latest firmware (v.11 ARM, v.10 DSP) and the AC Inverter randomly shuts off regardless of the load, even if the load is well under 600W. I did several extended tests with a pair of laptops and a lamp to maintain between 20W and 95W continuously but the AC Inverter claims it’s overloaded randomly within 12 hours.
My unit has stayed in “Standard” mode with “ECO” disabled throughout testing. The UPS function is unusable if the inverter doesn’t stay powered on. Even if I run it just from the battery, the AC output shuts off randomly, turning off downstream loads. I’m not convinced this can be fixed with further software updates so back to Amazon it goes.
I was able to generate a pre-paid shipping label to return the unit via UPS though Amazon’s return process. Pre-paid label says it’s heading back to an Amazon Return junction.
My first EB3A fail about two months ago when I was running solar and AC together so I sent is back and Bluetti sent me another EB3A. I put an external fan on the EB3A and AC output has stayed on for the past 4 days. Now I disconnected the external fan today and I will see if it fails. I will keep you all informed.
For what it might be worth, my experiences with using my EB3A as a UPS:
it is currently ‘hosting’ – acting as a UPS 2/for a Desktop PC power requirements are somewhere in the range of 75 to 80 wants (an AMD Ryzen 3600 Processor with 32 GB of RAM) ‘on average’ PEAKING at around 135 wants. ALL THIS is what computer NEEDS. Because of inverter losses, ON AVERAGE the draw shows up on both the display and the android app at around 100 W.
AS THINGS CURRENTLY STAND: my EB3A IS WORKING AS IT SHOULD as a UPS. I DID HAVE SOME PROBLEMS WITHIN THE FIRST WEEK AFTER I GOT IT trying to use it as a UPS. It seemed to run just fine for four or five days and then I woke up one morning and found that the computer had shut down overnight AND THE EB3A BATTERY WAS ‘100% FLAT’. AND I had a lot of problems trying to get it back up and running again… A LOT OF PROBLEMS. For a start, the unit would or at least was very reluctant to ACCEPT A RECHARGE. I left it plugged in seven or eight hours with no indication that it was recharging. (I recall wishing that there was some way to REBOOT the thing because I figured that would solve some problems…).
In the end, because I was/KNEW that there were a couple of firmer updates available WHICH I HAD NOT ATTEMPTED TO APPLY YET, I took a chance – even though I had some turns because the battery was ‘flat’ – that I might ‘brick’ the unit – I decided to install the updates using the app on my cell phone, ‘holding my breath’.
Well, the updates installed properly and the unit began to charge up FINALLY and VERY FAST, I MUST SAY – VERY IMPRESSIVE.
However, my problems did not completely go away – AT LEAST ‘INITIALLY’. I can’t remember what they ALL WERE at this time, though I had documented my experiences and had a number of back-and-forth communications with blue Eddie about the nature of the problems – but one of the weirdest problems seem to be that – while up and running as a UPS, IF – JUST FOR EXAMPLE – you touched/BRIEFLY PRESSED any of the other buttons to – say – turn DC outputs on or off OR EVEN TURN THE LIGHT ON THE UNIT ON, the EB3A WOULD SHUT DOWN! Causing the PC to shut down as well.
DUH! THAT SHOULD NOT HAPPEN, obviously.
Now I’m not sure what happened BUT that particular problem seems to have – and I must reiterate – SEEMS TO HAVE – extent self/gone away (though I haven’t tested it extensively but… More later…) And the unit has been functioning – as long as I’ve left alone and not attempted to do anything fancy with it yet in terms of dynamically turning things on and off and adding various loads to it – AS IT SHOULD AS A UPS.
After I had install the updates and got the unit recharged and managed to get it – apparently – which I confirmed – operating as a yes on this desktop PC in question, I ran a TEST by disconnecting the EB3A from 120 V AC ‘holding my breath’… AND NOTHING HAPPENED – which is exactly what should happen – the desktop PC in question stayed up and running.
‘As fate would have it’, at 3 AM the following morning we had a thunderstorm and I happened to be awake at the time (family dog/border collie climbing into bed with me because she is terrified of thunder!) and while I was awake, I noticed a brief power interruption – perhaps two or three seconds before the lights came back on – and I kind of wondered… If my PC had stayed up and running. The following morning when I checked, IT WAS (still up and running).
Since that time, we had a second power bump during a thunderstorm and again, the EB3A worked as one would expect it would/should.
SO, where do things currently stand with me/my EB3A?
Well, I have pretty much left alone AND NOT ATTEMPTED TO TINKER WITH IT for fear that turning the DC outputs on-and-off and/or the light on-and-off might trigger a shutdown… HOWEVER, I have done it – both – a few times and for whatever reason, this time around… (The only reason I have the DC outputs turned on his so that I can lay my cell phone down on top of it for inductive charging. However, I have turned the light on the EB3A on-and-off a few times AND the outputs on-and-off a couple of times also with no real effect. I am reluctant/have been reluctant to play around with it too much because if the unit shuts down, it takes the PC down that is hosting as well which is inconvenient; however when time permits, I will experiment around with it some more. As things currently stand, CURRENTLY STAND – IT SEEMS TO BE WORKING NORMALLY/as one should expect).
I WISH THERE WAS A WAY TO REBOOT THIS THING! I have a feeling a lot of these problems could be made to go away if one could just reboot it. I tried pressing and holding various available buttons simultaneously in different combinations and was able to get some interesting screens/displays pop-up but I don’t know what the heck they mean.
So again, for what it’s worth – those are my experiences. ALL IN ALL – I AM CURRENTLY SATISFIED ‘ENOUGH’ with the unit I purchased – while I did anticipate using it for more than simply a UPS, it’s UPS functionality (in combination with its overall features and capacity and fast charging and so on) WAS THE PRIMARY REASON I PURCHASED IT. In my opinion, assuming it can work as a UPS properly/should – it’s a ‘no-brainer’ for anyone looking for a decent capacity UPS: perhaps two hours of run time in the event of a power outage ON A DESKTOP PC, WONDERFULLY FAST CHARGING (when mine was flat, it went when I attempted to recharge it from 0% to 95% within an hour! And reached 100% within about an hour and 15 minutes) PLUS A BATTERY WHICH SHOULD NEVER, EVER HAVE TO BE REPLACED. EVER!
If only I hadn’t had the problems I encountered… However, we shall see – I originally intended to purchase two units but decided to purchase only one and perhaps a second before the special introductory price offer was over but decided to delay purchase of a second or possibly a third one, all to pretty much use as a UPS. (Another intended use as a UPS I have in mind is to use it to host a small 12 V DC COMPRESSOR REFRIGERATOR that I keep in my vehicle. That unit pulls only about 165 W hours every 24 hours and so one of these units should be capable of EASILY POWERING IT FOR A DAY AND ½ – or at least 24 hours. I could avoid inverter losses by using the DC operational mode of the refrigerator and that would be just wonderful… To have a 12 V refrigerator in your motor vehicle to keep drinks cold and stuff. Those things are really neat actually – from room temperature, they cool down inside to normal refrigerator temperatures in the mid 30°F range within about 15 minutes, AND they can even be set to operate as a FREEZER… Ice cream on picnics, anyone?
Again, if I don’t have any more problems with it and it operates as it should or at least as I think it should, I will definitely purchase a second and possibly a third (or even a fourth!) later this year. Probably around I would anticipate the Black Friday sales that occur in November these things will go on sale/there will be deals again…
In closing, for what it’s worth:
In this mode, in which it must meet a power demand of roughly 100 W from the PC – the unit is normally completely silent except for ‘every few minutes’– say every three or four minutes, I haven’t tried to time it – the internal fan will ‘kick on’ and run for perhaps four or five seconds – not long at all – to do some cooling of the inverter I imagine. HOWEVER, the noise is not bothersome at all! I sleep in the same room with the unit and don’t even notice it/ever hear it turn on and off unless I am right at the computer AND my EB3A is sitting right on the corner of my desk – very convenient for inductive charging of my cell phone.
Hope my experiences help/provide encouragement/consolation to others who have been having problems. I would say “Hang in there”. I’m pretty sure Bluetti will fix the problems…
Wish list
And finally just one thing I thought I would mention: I happen to have a ‘right angle’ computer power cord around that I swapped in and I’m using with my EB3A. There have been complaints about the fact that the AC charging ports – the 120 V one – is on the front of the unit. I ‘get it’…, And I agree. However there are right angle power supply cords available – you can buy them on Amazon for under $10 I think, and they definitely help. About the only problem that they might cause is the fact that want to be one of those individuals who would like to simultaneously charge the unit from solar, the right angle plug would get in the way… But heck you can have everything…
Ship it back brother , whats the problem?
