- In this video I modified the usb port (for data usage) in herman kardon speaker became a charger port. With this modification, we can charge the speaker using usb port and cable. Awesome :)

Thanks for this. My battery wouldn’t hold charge anymore. A new battery fixed the issue
Even my battery goes off after few seconds of playing.
Should I replace my battery?
Hello, the battery in my Harman Kardon (exactly the same model) has yet again lived its life. This is becoming too frequent. If I need to modify it to work directly with DC supply through a 5V input, any suggestions? Where I stay, I don't find the 3 pin 18650 battery easily available and then trying to see how I can mod. I can get 18650 batteries but this has 3 pin connector with a thermistor likely. Any suggetions else on how to run this with a single 18650 battery with two pins? Thank you
Does that 5V USB chargerboard downgrade to 4.2V witch is the right charging Volts for this battery?
The original charger IC of the speaker accepts like 4-20V as well so theoretically it should be possible just to add a jumper cable on the main board from the USB 5V to the charge IC. Never tried it though. But I added an extra battery last time I took it apart.
ive got everything apart and solder ready I wanna to try it but I don't know where to connect from point a to point be can u explain so I can try it thx?
Exactly what I wanted to do! Thinking of securing second battery to case with hot glue. dont want it rattling around in there!
One of the two speakers is give another sound..How can i change that one please. I love the speaker thou
So I got all the way to removing the usb charger but I am not a techie person just pissed my speaker isn’t working anymore - so anyway - I have three colored cords red brown and black - can you give me the dummies version how I make this one piece so I can move on to next step ? Assume I remove the white end and then strip the wires back? But I have no idea how to add those to battery… help
Excuse me, there are two plugs on the back of the device. One is normal plug and the other is mini usb. I charge the battery with the normal plug, but I don't know what mini USB is. Hello.
Donde consigo el cable adaptador?
Yeah great video. Try putting in a double fustash hangup adapter, changes the ballgames
Yeah, and a single mustash bread is as good to!
Um, where is that Mario music playing from?
Didn’t you have any problem after a while? You are charging the battery with 5v instead of 3.7v which many times can be really bad for the battery.
They are afraid of constant charging. I put out the battery on my Onyx 4. right after the warranty. The device was charged all day long, for 5 days. Accordingly, the battery is damaged. It is necessary like this: I charged it, and immediately turned it off. Well, to the full try to discharge. Sounds silly, and the super engineers did it. But the column sounds SUPER.
Hago el mismo prosefimiento y todo me trabaja nenos la nemoria
im guessing you lose the full power output for good, right? because the reason for such a higher voltage charger isnt just to recharge battery, its to give out max output at 60 watts. when used as portable only gives out half potential.. riiight???
Yes, that is true
I just switched out the battery and it still doesn't work when you unplug it . So I guess it's the cord
Good
That's great to know. What was the final result? How long it takes to fully charge the battery? Did you utilize same USB port hole? Thanks dude
honestly i never check it. sorry.

Boss panu malalaman kung nagchacharge yan,
Did you do this because the power cable stopped charging the device?
nope, actually i bought it without power cable. so i have to find a way to turn it on.
Mine doesn't show signs of charging when charger plugged in ... Anytime I on will keep blinking and off
Where did you find the lithium charger at
toby baca please where do I buy this board to charge? And How do you fix this board in the back cover of speaker?
My friend a pack of ten on eBay it's a micro USB power supply
And pretty much the video covers the repair really well you just need the part is all
