Thanks buddy! I checked my laptop adapter with my multimeter and got 0.L which means it probably has a broken wire.

I thought my dads speaker died but it was just the power supply. Very, very nice to know 👍🏼

I’m literally diagnosing my Jbl extreme speaker 😂 .. never had a power adapter die in my lifetime but I think it’s a first now !

@@5abivt it's incredibly easy to throw away something that has no problem at all, knowing how to diagnose those things is something really, really good! Now I have curiosity about all the other electric things in my house 😅

@@matheo4712 indeed !! This speakers worked great and talking to the wife.. couldn’t believe that it’s been like 8 years already .. seemed like 3-4. It’s always been taken care of I usually listen to it in the garage when working on cars. I have a digital voltmeter that I wasn’t sure was reading correctly but I brought the Adapter to work and tested it and same thing.. it’s putting out like 40 milivolts so I can order up a new one. Hopefully it’s my issue too glad you got yours working ! 👍🏼

@@matheo4712 wanted to update that is was my power supply in the end ! Both batteries charge well with a new psu. I’ll be taking the Jbl one apart to see if I can find where the issue occurred ! 👍🏼👍🏼

Question. What does it mean if power adapter is working but after having power for 20 minutes it starts humming loud and then if shake around it’s cable the humming cuts in/out?

Two adapter each 5 vdc output check out okay. Only one powers on device. I presume problem is in pin connection inside device. Will change pin connector.
