Take the battery tube off and check and make sure you removed the clear “tiddly-wink” from the recess in the driver. When you screw it back in for charge some blue lights at the switch will light up. The adapter will get warm but charges well. You will see the regular battery display moving up 3.4.5 then start over. When charged the display shuts off.
I am soooo glad I figured this out on my own :partying_face:
It’s charging now, and yes the power supply is hot.
I feel like a fool for this happening to me, I KNOW better!
But with the problems with the power supplies and the problems with unscrewing the battery while it was on, I made up my mind I was NOT going to mess with this one.
At all.
When I first unboxed it, it wouldn’t turn on. That should have been the clue, BUT
I recently got some Makita Li-ion drills that came with the battery packs installed on the tool. Usually they are packaged separately. The batteries have battery gauges built in and coming out of the box they read dead. Manufacturers always ship new batteries at about 3.6V per cell. When I put them in the charger, they instantly “woke up”
I had that in my mind when I first unboxed this light. The battery pack was shipped half full but in a “Coma” until it first hits a charger.
I was wrong
Tiddly Winks!
I suspect all will be fine now, have to wait 3 hours, 10 minutes to fully charge up
^ Well that’s good news… But what on earth is the display saying then? Nothing in the manual about it?
There is nothing in the sheet of paper you get with it about any of this.
The display is now as leroycp described.
What a surprise, the supplied charger just quit after the first hour.
I am continuing with the Fujitsu…………………
With so many failed charger mentioned here, why are you still surprised? 
Because I’m special, and it could never happen to me…………… :innocent:
I cut the cord of the original charger that blew and used it to check the current draw while charging.
1.91A.
That means the supplied charger is too weak.
I would think at a 4A charger is needed. The Fujitsu laptop charger I’m using now is rated at 4.22A.
I will let Banggood or Imalent know about the charger, but I don’t expect a replacement. That’s why I went ahead and cut the cord.
I know I can get all the laptop power supplies I want in the recycle bin.
Does this adapter compatible with DX80?

Okay, so now we know what it does when the charger is plugged in with no batteries, or no battery contact.
It seems that it can not be disassembled.The initial 5 minutes of charging was slightly warmer.I do not feel the need for cooling.
But although this is already broken 
The second one arrived today, but it has been broken since the beginning :rage:
At 19V, please select this type of plug.
As for the charging indicator,I think that it is OK.It reminds me the Sony SBH50 Bluetooth which I have,which when in charging condition has a indicator with the same movements.It shows the current situation and the maximum where it will go, when the charging is finished.
Edit.
As for the light,my jaws are still open.WOW.
Why? You had the light in your mouth for some quick close-up work? 
Congratulations on winning the IMALENT lottery. I am losing twice :partying_face:
In the story of gearbest I heard before, IMALENT seems not to be very cooperative with sellers.
I am relieved in this case like a problem only with the AC adapter. (The dchomak video was horror )
There was a reply of DX80 from BG.
They asked if the problem is only with the AC adapter or whether the AC adapter has failed due to a problem with the main unit. I think that the matter of my9221 has also heard the same thing.
1. Does the mode button on the unit function?
2. Can you charge with another AC adapter?
As just confirmed on the taschenlampen forum, the dx80 was measured at over 31,000 lumens and 5000k temperature. Not surprised. It was a beast when it tested it before mine blew up. Fix the electronics problem, Improve the switch and include high quality charger and this flashlight would be perfect. Waiting to hear back on my warranty replacement.
Link please
Too bad no throw candela number yet.
