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:
http://www.yesdepot.com/product/ud0520.html
I've ordered from them and the service was OK. I haven't seen the item available anywhere else.

USB/AC detection?

Hi,
I saw while using Tbattery 0.56 that when I plug the original AC charger that the S/W (Kaiser) detects it and therefore he pulls more current from the charger.
When I use USB cable, its detects "USB" and takes less current.
now for my question, I have a AC charger from Parrot and when I'm connecting it the device acknowledge it as a "USB" not "AC charger".
Does anyone know if there is an Hardware pin in the mini USB that notify the kaiser wether its USB or AC charger ?
Regards
Nir

Hi Nir
I don't have a Kaiser, but on my prophet I've had quite the same problem.
The USB / AC difference is about the current...
On my USB charger (able to charge any USB device), the current is 0.5A
On my AC charger, provided with my prophet, the current is 1A.
As a result, when my battery is completely drained, i'm unable to charge the device via a simple USB charger. I've got to give a kickstart using the AC charger.
Hope this helps.
David

I have diamond. same 'problem' (or more of a protection from current overdraw) here.
Actually the original ac adaptor shorted the USB data+ and data-
So you'll have to modify your 3rd party USB charger by connecting the center 2 pin of usb jack. you shouldnt do this on pc or laptop as this will render usb connection useless if it doesnt fry your devices.
Do it on your own risk!!

ohms law state
amp == volt / resistence
usb is spc'd volt == 5
max amp == 0.5
AC have a much higher max amp limit then usb
so the internet resistence of the pda set the pace
and it can it seems draw a lot more then usb is spc'd to
so it's not something the device actively does it just
try to draw as many amps as it's spc'd to
resulting in ac charger charging faster then usb

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 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 3.0 Charging

The Note 3 is the first phone to come with USB 3.0 support, the cable and connector are up to spec.
What I'm wondering if this helps with the charging speed, as the wall charger doesn't seem to be with a USB 3.0 connector.
Does anyone have any insight to this?
Sent from my SM-N9005 using Tapatalk

The wall charger has a 2Ah power output while a pc usb 3.0 port has a maximum output of 900mAh. If you use an USB 2.0 port it's only 500mAh.
The best way to recharge the Note 3 is to use the wall charger.

From a dedicated charger the final charging current is normally determined by the PHONE + CHARGER based on how the phone "recognizes" the charger as good/bad (and what battery level you already have + how warm the battery is) and how much power the charger can provide. I believe the max that I have seen on my Note 3 was 1800 mA (which worked with both USB3 cables but also with some good USB2 cables).
From a PC the charging current is the result of a more complex negotiation, the phone can still have "the last word" but it can not go over 500 mA on USB2 or 900 mA on USB3.
Somehow related - please note that on USB3 DATA you STILL need to MANUALLY enable USB3 mode EVERY TIME YOU PLUG TO THE PC. Even if enabled the mode will be reset to USB2 in 10 minutes and lost if you remove and plug-in again. That being said on my Thinkpad I have not seen it charging over 450 mA even when on USB3 under Win7 (but the speed difference exists, so USB3 is correctly triggered).
Also please note that the life of the battery can be heavily influenced by the charging current - the smaller the charging current the more cycles the battery will last on the very long term. Also high temperatures are pretty bad for the battery. So if you are in no hurry it is always better to charge with a small USB2 current that is guaranteed to not go over 500 mA.

Maybe I wasn't clear enough, I'm wondering if the wall charger is utilizing the USB 3.0 capability, and if there's any advantage of using the USB 3 cable over a regular micro USB cable.

No, there is not. The Note 3 has a USB 3.0 port, but it is only faster for data transfer. Charging is done at 2.0 speed, not 3.0. Regardless of what you attach it to, it charges just as fast as a 2.0 device.

What if you used a USB 2.0 cable with the 2Ah AC adapter? Would it still charge in "USB 3.0" mode and not give you a message to use a USB 3.0 cable?
I have my old 1Ah car charger and when I use a USB 2.0 cable, the phone says to use the USB 3.0 cable for faster charging.
But, looking at this pinout:
http://commons.wikimedia.org/wiki/File:USB_3.0_Micro_B_plug.PNG
It seems like only the USB 2.0 section is providing the power?
It's utterly confusing. Would be nice if someone who really knows this stuff explain how it works?

What's strange is that I have a car charger that is 1.0Ah. When I use a USB 2.0 cable, the phone tells me to use a USB 3.0 cable for faster charging.
When I use a USB 3.0 cable, the message does not appear.
But I'm thinking that the car charger can only put out 1.0Ah regardless of the cable that is used?

Does the S8/S8+ support 5v/3A charging?

Wanted to ask before I consider returning the charger I got
I tested this car charger
https://www.amazon.com/gp/product/B01E764DXM
Using this
https://www.amazon.com/gp/product/B01MT8MC3N
Results were
Using USB A to USB C cable - screen off 8.98v/1A-1.67A(amps varied during the 100mA test I did) - phone read Fast Charging
Using a USB C to USB C cable plugged into the USB C port - screen off 5v/1.8A steady (zero fluctuation) - phone read Cable Charging
Now the charger says it is capable of 5v/3A output out of the USB C port but that's not what I'm getting to the S8, which makes me wonder if it's a limit placed by Samsung software to not go for higher Amperage (and therefore more wattage)
When I look at the estimated charging times, the QC (USB A- USB C) is usually 10 min faster than the USB C charging

9x1.67 is the max the phone supports, on 5v you might get 2a tops, looks like the usb-c port on that charger doesn't support 9v for some reason.

Has anyone found and tried USB-C cables that support high-power 5a and for sale in the USA? https://www.startech.com/ca/Cables/usb-c/usb-c-usb-3-1-cable-power-delivery~USB31C5C1M
