Introduction: 100% Working USB Charging Adaptor for Creative ZEN V Plus MP3 Players

Here i will describe what you really need to charge your ZEN V plus with every 5VDC power supply!

1. You need the following parts:
- a Mini-USB connector with 5 soldering pins inside from a standard USB-A to Mini-USB cable (see picture 2)
- for the complete adapter a Mini-USB plug (see picture 3)
- a 470 Ohm resistor (SMD (code 471) or metall film because they are smaller as standard resistors)
- soldering implements

For myself i've made an adaptor (see picture 1, 4 and 5) to use my motorola RAZR power supply (see picture 1).

On the pictures 6 and 7 you can see that the (my) adaptor works!

To use this adaptor on every PC/Notebook you need additionally such an standard USB-A to Mini-USB cable (see picture 2).

Step 1: This Is Picture 2:

An standard USB-A to Mini-USB cable:

Step 2: This Is Picture 3:

Mini-USB port

Step 3: Second Version That Works: (i've Not Tested It, It Comes From an Universal Adaptor for the ZEN V Series)

The second version uses 2 resistors, 1 kOhm and 2kOhm!

In this wiring diagram you can see, how the both resistors are connected:

Step 4: These Are the Pictures 4 and 5:

Picture 4 is from inside the Mini-USB plug

Picture 5 is the complete adaptor with heat shrink sleeve on each connector

Step 5: These Are the Pictures 6 and 7:

In picture 6 you can see the motorola RAZR powersupply, the adapter and my ZEN V plus in charging mode.

In picture 7 you can see my ZEN V plus too in working and charging mode.

The Second version with 2 resistors, 1K+2K work for my ZEN V plus.
The 470ohm version does't work

thanks you so much, i was make it complete

Hi!
I stumbled upon another possibility to make a Zen V load (at least my one does) when I opened a very, very cheap charger. It had the D+ connector (green cable) connected to GND (black).
I tried multiple setups and ended up with this. Note that it isn't standarts compliant unless you remove the resistor (but then of course your Zen won't charge any more ;). Use it on your own risk ;)

Well, shorting the 'green' wire on an ATX computer power supply causes the power-supply to turn on. I have seen a lot of these 'homemade' charging schematics on the internet, and am at a complete loss as to why anyone is 'powering' the data +/- pins (pin 2 & 3). You are putting power into your data ports...where pin 1 and 4 are all you need to power. Then again, I am not familiar with many of these specific devices being 'charged', and so a trickle feed to the data ports may be required to cause the device to accept a charge. I see this as highly unlikely, but not definitive.

Keep this in mind, that a computer does NOT output data or power to pins 2 & 3 for any device, once it is connected, or data is being transmitted; however keeping it plugged in will charge it.

I do not recommend powering against your data-pins. I have blown up more than one motherboard circuit due to 'accidental' powering of the data circuits. Last note: test your charge circuit WITHOUT powering pins 2&3, before adding that 22k resistor circuit shown in the diagram above...most devices will charge with only pins 1 & 4 in the circuit.

I just noticed that your diagram is 4-pin, above, but if the zen is taking a mini-USB plug, then actually you are dealing with 5-pins. Now it makes sense. The 4th pin (beside pin-5) is not a redundant pin, but is used to tell the device if it is a controller or a peripheral. If power comes through pin 4, then the device knows it is a peripheral, and acts like one...hence, it knows to take a charge. Now it makes sense why you are using a small trickle through the 22k resistor circuit...you are fooling the 4th pin into seeing a trace-voltage, so that it knows to act like a peripheral and take a charge from the computer.

SIMPLE! Ok, makes sense. The Zen is actually 'computer saavy', and with the mini-USB plug - it isn't just there for looks, it is actually taking advantage of the 4th pin signalling to prevent 'surge' or 'amateur' tampering...like building chargers without understanding the charge circuit requirements. Interesting...

I did the first mod with 470Ohm resistor between 1st & 4th pin today. It works flawlessly with Zen V Plus (2GB, latest firmware) and some no-name USB charger, rated at 1000mA. Thanx to luemmel, you saved me a lot of money and effort trying to find original charger. :)

I would like to propose another way of doing things using previous comments
of  LUEMMEL and NERGAL8 that I used. Instead of modifing a cable I modified the USB CHARGER. I opened a USB charger, one of those commonly sold everywhere, and I disconnected the WHITE and GREEN cables from the output, so only the RED and BLACK cables where left connected (the two outer ones +5 & GROUND), then I soldered a 470 Ohm resistor between the BLACK and GREEN pins of the usb charger (the one next to the black pin). The system operated normally on my ZEN MOSAIC. I found this way easier and can be used on any car usb charger too.

Have you been thinking, how does this work with the PC with same cable without these resistors?

Isn't it clear the data signal (pins 2 and 3) are used with PC? There is no signal number 4 in the bigger USB connector. There is only two data, +5 and GND.

The signal 4 is defined as "ID" in the standard (http://en.wikipedia.org/wiki/Universal_Serial_Bus)

Have you tested grounding or +5 (susing resistors) with data signals?

I HAVE THE ZEN MOSAIC 8 GB I TRY MOTOROLA CHANGER TO CHANGE IT DID WORKING. SO I TRY THE ONE OF THE SOLUTION, BY MOVING THE RESISTOR IT WORK'S BUT I DON'T NO IF IT WILL CAUSE ANY DAMAGE TO THE ZEN MOSAIC.
