Here is a question for someone who understands electronics better than I . I bought a dual port USB car charger that supposedly puts out 2.1a per port. It charges my devices but slower than expected so I am doubtful that it is delivering the promised amperage.
Is there an easy way to measure the amperage either at the charger, the end of a USB cable or better by using some app installed on my Tab?
Here is the link to the device on Ebay. http://www.ebay.com/itm/251037335263?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
Thanks in advance.

The original Samsung Wall charger gives 2 amperes, The Double off yours!

Already I have gone through 3 car chargers for my note 2 cheap ones and a Samsung charger none work well charging. The best one was the OEM Samsung but there must be a broken wire in there cause it charges then stops i move the cord and it works again. So I am looking for another car charger that actually charges and wont break in a month. Please post your opinions and links to the charger you refer (with best price of course ).
Here's what I use. About the best for any normal use. Had it since launch and so far so good.

Anyone get "MTP initialization" when using the moto rapid charger? How do you get rid of it?

Just ordered the car charger off Amazon for $7.00 http://www.amazon.com/gp/product/B005DCCCTW/ref=oh_details_o00_s00_i00 will try it out. I'm still interested if anyone recomends any other car chargers.

Open up the charger and solder the middle 2 pins together. Or short the data cable.

Rather just buy a charger that doesn't require Modding.

I could have sworn it didn't happen at first. But now everytime it does that. And it charges so slow that its not even worth being charged. I've tried both ports in my car as well.

I've found that stock micro usb cable or any other micro cable combined with 2.1Amp(ipad) car charger worked best (faster/rapid charge)

I would recommend this charger definitely. Charges 2 smartphones, 1 iPad plus my note, or just my note.

This really is the best option (but I WOULD NOT SHORT THE CABLE). I downloaded an app that measures incoming amps and tried several car chargers. Most of them only output .5 amps. You are better off buying a car charger for the iPad (2.1 amps) or modding a normal charger as suggested and using any data cable.
I use a modded Power-Bolt charger with a retractable USB cable. This combination takes up the least amount of space and rapid charges my phone even if I'm using Google Navigation at the same time.
The Note comes with a normal USB cable and a shorted wall charger. The Note knows to rapid charge when it senses the short.
Rather than butchering either of my Kensington PowerBolts ......yet I chose to use Current Widget to measure output of basic Samsung microUsb car charger. Depending on battery level it registered over .9A at times yet on 2 hour ride last week w/ Google Maps it wasn't enough. I use ProClip device mounts, but for the hell of it bought Samsung's car mount today to see output of its included charger. Top measurement on 80%+ battery was 1.092A ?????? I'll let battery drain down and report back....

I actually just use a cigararette lighter/USB converter and use a USB/micro USB cable and it charges just fine.

If you do decide to butcher your PowerBolt, you won't be dissappointed. I'm getting over 1 amp now regardless of battery life or Navigation. It's a bit tricky with the PowerBolt Duo, but you cannot tell it's been modded.
You have to peel off the top sticker, then unscrew the top. I did not have a torx driver that was small enough, so I just drilled out the torx screws. Then you remove the top, disassemble the charger, and solder the two inner USB leads on the 1 amp side only. Reassemble the charger, add a drop of glue to attach the top, and put the sticker back on. Now I can charge my iPad3 and my Galaxy Note at the same time, while they're running.
I own both the single 2.1A port and the Duo 3.1A. What are you getting out of 2.1 ports? I don't remember getting over .992A with it. Am I wrong to expect closer to 2.1A?
I didn't look under decal yet, but own mini torx set.
Even though I own ProClip mount I bought Samsung Car Dock on sale at CompUsa to see what charging output the included charger produced and Current Widget measured 1.059A while battery was at 73%. It's the first time I remember getting over 1.0A
Where to buy the OEM charging cable for Note 2?
How can you tell if the cable is capable of 2 Amp current?
Here's an OEM charger and cable on Amazon, probably find them on ebay too.
http://www.amazon.com/Original-Char...ords=samsung+oem+charging+cable+galaxy+note+2
Its the charger that needs to be 2A capable, rather than the cable. Any decent USB cable should do.
I ordered this one, supposed to be here Monday, will let you know how it does.

Charger showed up yesterday, according to battery monitor widget. It's putting out as much power as the original. It is a knockoff brand though, the printing on the charger doesn't match the original, all the text is the same, but it's a different size/color. If it continues to work as it does now I'll be happy with the purchase.

I've never owned a wireless charger. But from what I saw from looking in the forum for my nexus 5. They take much longer to charger. In fact it goes usb 3.0 (fastest now) at like 1 1/2 hours or so, then micro USB at like (3 hours), then wireless charging supposed to take double the time of micro USB. It more for over night use not a quick charge. Hope it helps

With the included AC adapter, the S5 can charge at up to 2.1 amps or so. USB 3.0 maxes out at 1.0 amp, and wireless chargers are about 0.7 amp. The slowest is really USB 2.0, which is only like 0.45 amp.

A good and essentially correct summary. But there are exceptions and cavets.
While most USB 2 ports are rated at ~ 0.5A it varies and newer notebooks in particular may have USB 2 ports capable of 1A +.
Most AC adapters (aka travel adapters ) are typically, either 0.7 or 1A. But a decent full size AC adapter will be ~ 2A.
Also note that the phone will limit it's current draw when using a standard data cable so as not to overtax an USB port. To maintain a maximal charging rate when connected to a high capacity USB 2 port or USB jack on an AC adapter, a "charging" or power cable should be used. A charging cable has the two data lines shorted, to let the phone know that you are (ostensibly) connected to a high current source, rather than a standard USB 2 port.
And wireless chargers vary substantially in maximum output current from ~ 0.3 to ~ 0.9A. Most are also sensitive to ideal positioning. A randomly placed phone may charge at a substantially reduced rate, due to the reduced coupling efficiency of a random orientation.

So if I plug my wireless charger into the white plug in adaptor that came on the charger that came with my Gs5 new that would give me maximum output voltage to my wireless charger?please correct me if Im wrong. Thanks In advance!!!

I got my phone today, and one of the first things that I did was test all of the Chargers.
My first thought is that the one plus cable that I bought is very high quality. Every charger that I tested, it charge faster than the cheapo ones that I bought on Amazon.
However, what I've been consistently surprised with is that using the same cable this phone charges faster on a Qualcomm quick charge 2 charger than it does on a standard USB charger. I've tested this with all sorts of Chargers around my house and I'm consistently seeing around 1500 when connected to a quick charger, and only a thousand when connected to a standard charger.
The USB C charger that came with the phone is significantly faster. However I wanted to share this so that for those others who bought all sorts of Qualcomm quick charge 2.0 Chargers, don't throw them out. They're still better than a regular charger.
Yeah on a good USB 3.1 cable (nice and thick) with my standard quickcharge charging block (7 ports, 60W total IIRC) I get 'charging rapidly' and it charges better than 1% a minute - about the same rate my N5 did on a much smaller battery. I've still not taken the google charger out of its box yet.. Need to get around to testing it even if I can't see myself using it.

I am curious as to what "standard" chargers you are using. I have a wall charger rated at 5v 2.1a (non-QC) per port and a car charger rated at 5v 2.4a (non-QC) per port, and both of those charge at 1500ma. Is it possible that your "standard" chargers are only rated for 5v 1a output?

Bought that one though still waiting on my phone. Like that it has micro USB too for other devices. Charges my HAM2 very fast.
Your results have nothing to do with them being QuickCharge bricks, I have a inline amp meter and I can get 1.5 on any brick with an amp rating high enough, not just my QC bricks that I was using with my Moto X. At least people will know if they have a QC brick they'll get at least that though.
I didn't know this thread existed. I'm getting what I think is pretty poor performance from the stock 6p charger. Please see this post:

Hello if anyone still has this phone do you have the same issue I got this phone last week (it does what I want and I am 12)it would not charge from a outlet but if I plug it in as a USB on my Wii it charges but it is so slow and I can't find a fix for it

This cable fixed it for me, buy a couple just in case the cable begins to fail (which they do). This cable increases in charge & charges to 100% fast while hitting the hotspot hard.

Try this charger too, it's 2.5 Amps vs the stock 2.0 Amps Charger, so using the above Premium High Quality USB Cable & This charger will ensure very powerful charging rate.
