Power Supply

#1
Hello all ...
Just a quick question please
I have two minix neo u9 devices , it seems I misplaced the one power supply , I know it uses a 5vdc 3amp power supply because that is what the one player use that I bought new
The other power supply I have is 12vdc 1.5amp , I do not know if it came with that second hand player that I bought and If I have been using it all this time?
I am just afraid now if I plug it in something bad will happen to the player
Do you guys think it will work with the 12vdc 1.5 amp power supply ??
Thanks in Advance

NO!

Never connect over voltage power units to devices. That is a total killer. Over amps is fine, over voltage is not!

You need a 5 volts Direct Current with at least 3 Amperes!

First I must say, I would never knowingly connect a higher voltage!

FYI As far as I'm aware the U9-H does have power input protection. ie: if you connect a higher voltage it will know (Power LED Red) It shouldn't cause any damage.

The device will not function though!

You need a 5V PSU but I believe you can "get away with" less amps than 3A. I was told that the 3A was to power external USB devices. So if you aren't using any heavy powered USB devices and have a spare 5V 1A or 2A PSU with the correct sized tip (the bit that plugs into the U9-H) then it should be fairly safe to try it on your U9-H. The only thing to be wary of is the polarity of the tip but most PSUs and the U9-H use the tip outside as ground and the inner part as positive (5V in our case) since this makes it safe to hold the outside metal of the tip on your hands. However, there is always an exception to the rule!

Thanks for the reply....
I did try that 12v Psu and like Villa said there was n blue-purple(ish) light so yeah it has overvolt protection
I found another psu 5vdc 1.5A and it is working as it should , I am not using external drives and thanks I checked the polarity with my multimeter , I once blew a power supply on a laptop because of wrong polarity ...
I have two U-9H players and a U-1 , To be honest I think it is one of the Best players out there talking about the U9 , it plays all my files perfectly never a sync issue , The HDR works ,Dolby Atmos work , True HD work ,I only bought another player because of Netflix and DSTV(Our satellite company)which do not work on the U9
Thanks

My best use of a 12V PSU on an Android TV box was to plug it in to a cheap Android TV box thinking it was a 5V PSU. Needless to say it didn't have over voltage protection and that was the end of that TV box. I wasn't too bothered as it gave me the perfect excuse to upgrade to a better one (my U9-H)
