Yesterday my light that worked for the last 2 month connected to the AC turned of suddenly and the Display on my EB55 showed “SHORT” on the display. I unplugged the light and throw it out.
Then I’ve tried to tun on the AC Output again to charge my DJI drone but the AC keeps showing the SHORT problem.
What can I do? Is there a way to restart / reset the EB55 completely, is the AC part of my battery dead now? Is the a fuse I can change on my own?
The unit is 1 month old it would be sad to not have AC anymore.
Any ideas what I can do ?
Read the fing manual doesn’t work in this chase because there is not a lot of information there.
Try holding down the AC power button for 5 full seconds until you are absolutely sure the main power has shut down. Then…try a re-start and see if that solves the issue. If not, try to charge the EB55 for a few minutes and see if it accepts a charge. If those two things do nothing, I would contact Bluetti Service.
I’m having the same problem as described in this post. Is there any update on how to fix it? I made a video to demonstrate the “Short” problem I’m seeing for AC power on my EB55.
Here are the main points:
The unit charges fine
The 2 DC port areas work fine
AC doesn’t work - the “Short” error appears when the AC button is pushed
The “Short” error disappears when the AC button is pressed a second time
resetting by pressing 2 buttons at the same time for 5s doesn’t help
I received this unit just less than 2 months ago, and was very happy because Bluetti provided a new unit as a warranty replacement. I’ve been using the unit regularly since then, although I haven’t used the AC for at least a week. Then today I tried to to use it (to recharge a shaver, which I’ve charged before with the EB55 without problem) and noticed the “Short” problem.
Hey @T_o_n_y ! I personally LOVE that unit and its been my “go-to” for our day trips for nearly 2 years so I am sorry to hear of your issues with the eb55!! First off, to reset the error codes, you can just turn off/on the output, and it should clear them rather than the 5-second press or whatever. But yea it looks like there definitely is something going on with your AC inverter. It shouldn’t be throwing that short error with nothing even plugged into the ac outputs like that. I would go to this page and submit a request, and @BLUETTI_CARE will do what they can to get you taken care of promptly!
Make sure you upload that video and I would just copy/paste exactly what you showed above to give them as much details as possible.
I agree about the EB55. For me this has been a great unit, and I’d go further an say Bluetti customer service has been great as well. My first unit developed a problem with the power-in charging port and I learned from that experience how important it is to protect those ports. I wrote a 5-star review after Bluetti shipped me a new unit at no small expense.
But with this AC “short” problem I’m puzzled. I use those ports rarely, and they are also quite sturdy and since they are buried deeper within they seem quite protected. I certainly can’t see how I could have done any damage to them. Further, the device I was trying to plug in today is one I’ve plugged in before and it draws extremely little power. No idea why there is this problem this time.
Thats great to hear about your positive experiences with the support team. They have really stepped their game up this past year or so which is awesome to see. & Yea thats a rare one to see pop up for this unit. And SUPER unfortunate that its happening on an already replaced unit… so sorry @T_o_n_y… I definetly dont think I would want to take you to vegas or the casinos anytime here soon… Thats some rough luck!
@BLUETTI has your ticket tho and will respond soon to get things remedied for you asap. Keep us posted man!
Cheers!
