Wizard Car Charger

So I visited my local Walmart and discovered a car charger, designed for Blackberry 6200 through 7500 and Motorola RAZR series phones.
The connector is the same, mini USB B.
$25,000 Question: Can I use this to charge my TMO MDA? Same connection, just worried the voltage or wiring might not be the same.

The AC chargers that came with my Razr and MDA are the same voltage-wise (5V) but not the same Amps.
MDA is 5V 1A, Razr is 5V 0.5A, they are not the same
However, it shouldn't damage the battery, just charge slower.
Just so you know, USB ports output 5V at 0.5A as well.
Edit: Sorry, I realize I completely changed my post, but didn't want incorrect info out there.

Thanks...I figured that, but was just making sure.
I got it in case of emergency...I almost always charge via USB; just leave it plugged in all day.
But you never know.....
Thanks!

Don't expect it to charge if you battery is below 30-20% charge. I'm not sure why this is an issue but it has bitten me in the rear once already.
Does anybody know why it's a problem for "less-than-1amp" chargers to charge back from the low threshold?

boxwave.com sells a 1 amp car charger. It has a USB port, so you just use it with any cable that normally plugs into a USB port. Since my Globalsat GBH-820 BT adapter came with a cable with large USB at one end, and _two_ mini USB at the other end, I can charge the GBH-820 and my 8125 at the same time.

That's not true,... if you use the VersaCharger like I do. This is where I learned of the "charging only" cable that Boxwave sells (how conveinent) and then they sell a Sync/charger for USB only. I have a Boxwave VersaCharger that I can't use without buying their "cable" to make it charge the 8125. I found this out because I have a Belkin retractable sync/charge cable that doesn't work with the VersaCharger as I had hoped. The cable that you have may work with 1amp charger but it probably won't work with theVersaCharger.
What is the output on the "min-usb" connector end of the cable? This sounds like the cable that I need for the 2 devices that I use.
...I wonder if they are putting some electronics in the cable connector...?

I bought the bundle that had a car charger (I have the regular; not the high output; not the Versa) and two mini-Sync (retractable) cables. I got caught by the fact that one of them is "charging only" when I was trying to use the "charging only" cable between my laptop and my TI-84plus calculator. I switched to the mini-USB cable that came with my calculator, and it worked fine, as did my phone with AS. That's when I looked closer at the two mini-sync cables and noticed that one was for "charging only". So, that mini-sync cable (the charging only) stays in the car, and works fine for charging my phone or my GBH-820. The really odd thing is that the "charging only" cable looks "thicker" than the one that works for syncing. Maybe lower gauge wire to help the higher current flow easier.
I have also used my other USB-miniUSB cables with my car adapter. E.g. the cable that came with the phone, the cable that came with my TI-84plus calculator.
My Bluetake headphones came with their own USB cable that has, for lack of any better term, an ultraminiUSB (or some kind of proprietary connector, cause it's not marked with a USB symbol like the other cables) plug at the end. I just plug the regular USB end of that cable into the car charger, and it charges the Bluetake's just fine.

Excellent car charger for Wizard
I have purchased and used the "Ecovell 4x USB" adapter on both a Wizard and a Universal. It provides a 2 Amp output which is equivalent to the AC adapter and works with any mini-USB cable. It will charge a Universal from absolutely dead which I have not been able to do with any other adapter. Here is the link to the item on Yes Depot:

I've ordered from them and the service was OK. I haven't seen the item available anywhere else.

Fast USB Charging on O2 XDA Mini

HI Friends
Do you hv any software to carry out fast USB Charging option, to charge my XDA with same speed as done by AC Adapter...
I have seen that other WM2003 models has this option.... like in HP 6515..
Thanks
Manmohan

Interesting... I've got a desktop holder which has to modes: charge-only and normal sync/charge mode. I wonder wether charge-only mode "enables" fast charging or wether the AC adapter does something special...

If i'm not mistaken, the typical USB port outputs 5V of power at 500mAh (milliamp-hours). And in my case, my shipped charger outputs 5V at 1000mAh . using the supplied charger would charge my Magician twice as fast compared to the USB (explanation below). I think even USB2.0 ports still give out power at 500mAh.
The Magician's battery is rated at 1200mAh. Charging through the PC's USB port would take roughly 2.4 hours. Using the supplied charger, it would take 1.2 hours. Simple equation for charging is, battery rating (mAh) divided by charger rating [so that's 1200mAh/500mAh for USB]. Disregard the voltage for now unless you plan to make your own standard/portable charger. Rule of thumb, refrain charging the battery with a higher mAh rated charger.. It will damage the battery in the long run.
Hope this helps. Cheers!
Although if you could somehow control charging via software that'd be a nifty tool...

i doubt it since max current USB can provide is 500mah as any more would damage the port and probably the board.

Hello
Yup, jedhonx your right! Its the amount of power supplied! There is no way that you could use a software to charge the device in USB at faster rates.
The only way it could be thought of is like, if your device processor is running at certain spped, it consumes some power. When it runs at lower speed, it consumes lesser power and so if the software could make your processor run low or to shut down other programs maybe would show you an incresed speed of charging!

One of the following three thing WILL happen if ALL of them...
1-Fried Motherboard
2-Fried Battery
3-Fried Device
The first can happen because the USB ports will send energy to each other, the other two because voltage WILL duplicate... Think like this, when you have a device that uses "normal" batteries like a remote or a portable cd-player that uses two or more 1.5V batteries they use it because the device works with 3V (2*1.5V batteries)... Hope I made myself clear, because my english is quite rusty...

Well if you link USB ports to increase voltage it's true that it'll probably kill the mb. But linking 2 UBS connectors to increase amps is no problem and often done. You end up getting 5V 1A output. You could even link more ports to further increase the maximum supplied amps, alltough I never tested more than 3.
Linking 2 ports in a way that increases amps will NOT fry the mb, will NOT fry the battery and will NOT fry the device.
I'd say give it a try and see if it charges quicker.

Actually I think it depends on how many separate USB chips are connected to the USB ports. On one chip (or better say channel) can be more than one port be connected on the computer (like with a passive hub). In that case, connecting two USB cables in parallel doesn't change anything. Otherwise you could connect the cables in parallel and simply get more current at the same voltage (not to mix up with setting batteries in serial).
There are USB chips on the market that supply more than the specified 500mAh, but I suppose the Magician itself detects a USB connection to the computer. I remember that the first ROMs could only be loaded by USB chargers when Pin5 was connected to Ground, which was never necessary when a real USB connection was established to the computer. USB connections to the computer only use 4 Pins. This tells me that the Magician distinguishes between a connection to the charger and a connection via PC USB and limits the power drain correspondingly. If that is the case, connecting a cable with two USB ports doesn't help, it's still recognized as PC USB connection by the Magician.

it maybe OOT, but still relates. my magician can only be charged by usb cables. wont work on ac adapter. it has been going for few months and it really bugging me since it takes 4 hours to charge through usb cables.
i did try hard reset and no change .

HI Friends
I appreciate that you are trying all your mind to find the solution..
I believe that O2 provied AC Adapter wont pass additional current to screw up the battery life as it is provided by O2 Manufacturer itself. If Adapter takes 2 Hrs to completely charge the O2 Mini, then this can be done by USB cable also.
Also if you see in any other PDA running windows mobile 5 you will see an option of "fast USB Charging"..
It means that it can be done, but we need to find out how it can be done.
Thanks

Car Charger?

Does anyone have a confirmed working car charger for this phone?
My motorola car charger that I used for my GNex and GS3 isn't fully compatible with the G2. I get a message saying "slow charging" when I plug it in.
What do you guys use to achieve full charging speeds?
I realize there's a Q&A forum, but since this is directly related to accessories, I wasn't sure if it was better suited for this forum.

Nobody has a working car charger?

Both of these work for me.

the powerjolt is much more low profile though

That's just a generic list. The G2 requires a hi power charger

The powergen dual port works great. It has two 2.1amp USB ports, one that works with Android, and the other with Apple products (when using a data cable --> detecting USB vs AC charge mode). I have custom USB cables where I shorted the data pins so I always pull at AC charge rates regardless of the port type. In any event, this charger should provide you with the same capability as the OEM wall charger.

I have a 2amp car charger and it works fine, no message about slow charging.

the issue im runnin into is find a usb cable that enables fast charging
i have a dual usb car charger that put out 2amps per usb but cant.find an aftermarket usb to micro that can support more amps (fast chargin)
the oem lg g2 cable works...as well as the nexus 7 cable
i got this cable but doesnt charge more than 1amp

To short the data pins, I actually cut a USB cable, stripped back the insulator, re-soldered the +5V and ground wires, soldered together the data pins on the microUSB side of the cable, and stagger cut the data wires on the other side. Prior to the re-soldering, I slipped some shrink tubing on one end of the cable to re-insulate everything. Not for the faint of heart.
Background for those that don't know... Typically, Android phones look for little to no resistance on the data pins to detect a high current charger. Any other load triggers USB mode since most PC's are only designed to supply 500mA via USB. I assume this is a safety issue to prevent overdrawing a PC's port. Apple operates differently. They look for some nominal resistance as USB and switch to fast charge under open or some higher resistance. Most chargers >500mA are designed for the iPhone market unless they explicitly state other compatibility. Therefore, the data pins are floating. Any charger can be used at its max rating if you trick the Android phone with the homemade cable described above. Of course, then it becomes a power-only cable, useless for data. Clearly, OEM chargers for Android phones short the data pins internally so your OEM cable can be used with a wall charger (fast) or with your PC for data connections and nominal (slow) charging.
So the powergen mentioned above has two 2.1A ports, one labeled NA (non-apple) and A (apple) so you don't need to worry about mix-n-match devices and cables. Any USB cable will fast charge on the appropriate port. With my homemade cable above, my Galaxy Nexus will fast charge on either port.
Fast forward to the G2... Just got it yesterday and while in the car, I noticed my homemade cable only permitted SLOW charge on either port. Huh. Kinda a head scratcher. I ran in the house and got the OEM LG cable and both ports worked with FAST charge. So I tried one more thing, I grabbed a regular USB cable and observed the following: the phone went into FAST charge on the apple port and SLOW charge on the non-apple port. I can only assume that LG is detecting fast charge in a different way. The fact that a standard USB cable doesn't work with the data pins shorted at the charger but the OEM cable does makes me think there is something about LG's cable that allows it to pull max power from the charger. FYI, I plugged the OEM LG cable into a 850mA Motorola AC charger and it registered as SLOW charge.

I have pretty much the same thing, had a cable that would only do slow charge, so I stripped the wires back, and on the micro usb side I cut the green and white(data) and twisted them together. Now its fast charge no matter what charger I plug this cable into.... not sure why urs isn't....

My AT&T branded charger doesn't give me the slow charge notification.

Yes, but its not a 2 amp charger. We want a bigger fast charge vehicle charger...

I tried the USB plug in my car (Scion 2012) and two different Belkin cigarette/USB chargers today. The USB and one of the Belkins gave slow charging. The other Belkin did not -- worked fine. They were supposed to be identical, but I had suspected one was a fake. Guess I was right.

I just use the usb cable that came with their phone and plug it into my auto usb or the car's 110 outlet.

USB C cable question

Just wondering before I buy a oneplus 2 does the cable work on every other USB charger plug like all android phones? I'll have to order a non UK plug but if I don't even need to use the supplies charger and can just plug the cable into another one it'll be perfect

It should work, though charging speed may vary and might cause eventual damage to the OP2's battery.

Yeah seems to work on any that I have tried. I have tried it on at least 5 different chargers with different USB leads and a Type C adapter for the leads. Just varies the charging times.

USB Type C for Nexus 6P

Quick question for you.
I've just ordered a Nexus 6P and will have to change all my chargers at home and at the office.
Of course I'll only use cables purchased at the Google Store or cabler reviewed by Benson Leung.
What about wall chargers? Can I use 3A USB Type A chargers or should I upgrade those as well?
Thanks and sorry for re-posting. I just haven't found antyhing about the bricks. Only the cables.

A charger with a Type-A socket paired with a spec-compliant Type-A to Type-C cable will be able to provide a max of 2.4A of power. The only way to get more than 2.4A out of a Type-A charger will be to use a non-compliant Type-A to Type-C cable. In reality though, few chargers out there will actually give you 2.4A.
A charger with a Type-C socket and a Type-C to Type-C cable can do the full 3A while following specs.

Ok, but will the use of a compliant (Google) A to C cable and an old 1A-2.4A charger damage either my phone, the carger or the cable?

No, it won't. Googles cable is safe to use.
Googles A to C cable is properly designed. If you use a complaint cable (correct 56k ohm resistor) your phone will see it as a legacy charger and pull what the power brick allows it to pull.
Whereas, a non compliant cable (non 56k ohm resistor) will read as a USB 3.1 type C to type C cable to the phone; so it may (will if it's low on power) try and pull 3A out of a cable and power brick that don't support 3 amps.
