will a Razr wall charger work with a wizard?

[justyntime]

They have the same connection dont they? What about current, amperage and all that good stuff?

[victoradjei]

We can deduce from the fact that they both can charge on your pc USB slot that their individual chargers are of same polarity and COULD be interchangeable. A quick check on my collection of chargers that charge also on USB is: K-Jam 5v 1.0 amp max, Atom 5v 1.0amp max, Jabra 800 6v 205mAmp 8) Check with your razr charger and interchange the chargers at your own risk :lol:

NO NO NO NO NO NO NO NO NO

Don't do it, I had somebody who had been charging there Compact with a razr car charger and now it won't charge at all. There appears to be some difference somewhere. Don't even risk it.

It wasn't the fact that the car charger was for a RAZR, the problem was, it was probably a generic charger. I fried a brand new iPAQ with a car charger I bought on eBay. I learned my lesson...

The *OFFICIAL* Motorola RAZR charger is rated less than the Wizard. Both the RAZR and the Wizard can charge via the USB. Both have the same pin outs. If the RAZR charger were rated higher than the Wizard, you should be concerned.

I've been using a RAZR charger since I got my K-Jam in (when was the very first shipment?) and it charges fine every time.

The ratings on my Motorola V3 charger:

Input: 100v-240v ~ 50/60Hz 0.2A
Output: 5.0V - 550mA

If someone can explain how why the RAZR charger is bad on the Wizard, I'd love to know why.

In fact, Nokia sells two different chargers. On some phones, they come with a standard charger. But you can buy a "fast" charger for the phone and the only difference is a higher AMP rating. I used to work for Cingular and have seen personally the same phone ship with both chargers...

Power supply

The USB connector provides a single nominally 5 volt wire from which connected USB devices may power themselves. In practice, delivered voltage can drop well below 5 V, to only slightly above 4 V. The compliance spec requires no more than 5.25 V anywhere and no less than 4.375 V at the worst case; a low-power function after a bus-powered hub. In typical situations the voltage is close to 5 V.

A given segment of the bus is specified to deliver up to 500 mA. This is often enough to power several devices, although this budget must be shared among all devices downstream of an unpowered hub. A bus-powered device may use as much of that power as allowed by the port it is plugged into.

Bus-powered hubs can continue to distribute the bus provided power to connected devices but the USB specification only allows for a single level of bus-powered devices from a bus-powered hub. This disallows connection of a bus-powered hub to another bus-powered hub. Many hubs include external power supplies which will power devices connected through them without taking power from the bus. Devices that need more than 500 mA must provide their own power.

The max that the USB port can put out is 500mA. The V3 charger is between the USB port and the official HTC charger.

USB: 500mA
RAZR Charger: 550mA
HTC: 1A

Don't buy a generic charger. Buy a name brand charger...

Also, for more details about the USB pinouts than one man can digest in one sitting, read that entire Wikipedia article. I did... wish I hadn't.

the same discussion is going on over at hofo or ppcdubai, forgot which one, but thers several posts with "I know someone that...." or "my friend did..." and devices ended up being fried. well i'm telling you from first hand experience. about a year ago I bought a belkin razr car charger from walmart and i've been using it on my jam and now my k-jam and my battery and device aren't damaged. I don't know the rating on it but I suggest u check the rating of anything before u plug your device into it.
also that car charger didn't charge my sp3i, just to let ya'll know.

[McHale]

That discussion at HOFO was a question that *I* originally asked back in December. I just posted the same information over there about 5 mins ago.

Buying chargers for 4.99 on eBay will kill your device every time. I learned the hard way. If you buy a name brand product, your fine.

Specs says it's OK. Experience with a name brand charger (your belkin and my Motorola) says it's OK.

But like I said above, if someone can point out a hole in my logic, please tell me. I've been wrong before but I don't think I am on this one.

Motorola branded AC charger, rated for 550mA current
Generic car charger for mini-USB, made in China eBay, no specs.

Both work fine with my Razr V3 and my Qtek 9100. Bit of a risk to use the car charger, but it's worked well with the Razr. Agree completely with McHale, your logic works fine. If your AC converter and DC power source are up to USB spec, you should in theory be able to charge both devices.

The unknowns are the custom circuitry the cheap converters use to "prevent" overcharging. Some have simple diode rectifiers, some have weak op amp current sinks, etc. Basically, some of these overcharge circuits don't work at all and you get a fried device. You get what you pay for, usually.

Hi

I have 2 phones - an O2 XDA Mini S (a K-Jam) and a Motorola Razr V3. I use the Motorola chargers, both wall charger and car charger, every day for both phones and have done so, without problems for months.

nope, doesn't work. Simple as that.

I have both, I tried - used one at the office, the other (razr) bedside. The charge light comes on, then goes out in five seconds.

Every once in a while, it actually would charge... finally gave up and got rid of the razr charger.

[shaunconn]

Hi

It definitely works for me - I have actually never used the O2 charger; I use the Motorola wall charger at the weekends and the Motorola Blue Car charger every morning.

That is the only way I charge my O2 XDA Mini S - so it obviously works in my case!!

I have been using my Razr charger (car and home) since I got my KJam a few months ago. I had a surge and my official charger was fried in a surge.

The only problem I have had was when I completely drained my battery (GPS software that prevented power down) I was not able to bring my KJam back to life with the RAZR or USB charger.

I connected my KJam to a friends official charger for a couple of minutes and it was fine.

I bought a new charger from Expansys, but I still use my RAZR chargers as well.

[McHale]

I don't understand the reasoning, but you can not charge the phone via the USB unless it is on. Since the RAZR charger is basically the exact same specs as a USB port, same rule applies.

If the battery is dead, there's no way to turn it on for it to work.

At least that's my uneducated guess.

But like I said, I've been using the RAZR charger since the end of December and have never had a single discharge or any other problems.
