I've been using a mix of old and new USB cables for charging and have noticed that some micro USBs from my Blackberry days will charge the TB but VERY slowly, even using the wall charger.
I want to order some more fast charging USB cables, but how do I identify the difference? What IS the actual difference between the cables?
Thanks!
Usb charging is normally slower than AC wall charging. Most cables are designed exactly the same but some chargers are suited for more amperage per hour. I'd recommend downloading the app -"battery monitor widget" and plugging in your charger and seeing what type of miliamp per hour rating you're getting off of that particular usb port. If the port is in front of the computer, normally those get slightly less voltage than the main ones in the back. Also If you're rooted make sure you aren't on an old outdated kernel that has trickle charge coding thats messed up. I normally get 500-800ma/h based off the AC wall chargers, and anywhere depending on what computer (Work vs Home) USB ports anywhere from like 150-350ma/h. Hope that little tidbit helps.
It is a bit complicted.
When you simply apply power, the Thunderbolt (and most micro USB phone) charges at a slow rate. I have measured this at around 350ma max on the Bolt. This is mainly because the USB port power standard on a PC is 500ma max. They need to stay under that.
By the micro USB standard, if you tie the two USB data lines (D- and D+) together, then the Thunderbolt goes into a fast charge mode. I have seen around 850ma max. You can place a piece of aluminum foil on the charger end (large USB) to short out the two center pins only and switch it to high rate.
Some cables tie the two wires together. Those are fast charge only cables that you can't used for a USB connection. Some chargers tie the two wires together. So they fast charge with any USB cable.
What gets complicated is that of course the charger needs to be capable of about 1 amp for the fast charge to work. AND, some cables use such small wire diameter, that they can't carry the high current rate. I have a couple of cheap cables that even on the fast rate, only carry around 300ma.
AND, if you have time, charge at the low rate. The battery and phone will run cooler, and the battery will last longer. My overnight charger is the lowest rate that I can get by with. But I need to use a super high rate when using the GPS on my motorcycle to keep up with the bright screen and such.

I did this for my CaseMate battery backup and was able to get 800ma charging from it...
If you are just looking for a good car charger, i highly recommend the Motorola Rapid Charger from amazon, they are about $5 shipped. Those charge at the AC "Fast Charge" rate.
converting usb standard to fast-charging
Basically, the cable that came with my tablet, which allowed fast-charging, crapped out. I bought what I thought was the same cable and it still didn't work the right way. In searching through the forums, a a phrase hit me... two-pin fast charging cable. Seeing that, I took a small knife and a pair of needle-nose pliers and extracted the two inner pins( data pins) from he USB side of my cable. The cable, without the data pins, became a dedicated fast-charging cable. I have done this process with three cables so far to see if it was a fluke and every one is capable of fast-charging. I hope anybody that has been hitting the wall on this, reads this, because I was getting very frustrated with the convulated answers some people were giving to address this (especially from Munich!). Try it out, you can bury me in ashes if it doesn't work for you!!!
It's not the cable, it's the brick you're using. My nexus 7 charging brick has a higher output than my tbolt brick, so I use my n7's to charge it in a fraction of the time. Never rely on your computer's usb port to charge your device especially if it's your daily driver
I am looking for a really long charging cable. I know about mediabridge, however I am looking for something longer. It needs to be minimum of 8ft. It needs to be a high speed charging cable. Data is nice but not necessary. HTC's OEM cable is amazing, but I need a cable which is at least 8ft. I have looked at previous forums for this and have not found anything, that is why I am posting. PRICE IS NOT A CONCERN, I'll pay $20 for such a cable, it just needs to be good and high quality and have rapid charging. Thanks.

Plenty on Amazon. Lengths usually go 3, 6, then 10 feet.
I see a few for 5-8 dollars with prime.
Could also go go monoprice.com
Seems like you didn't search very hard.

You really gotta search some more. Amazon has GREAT cables, but mediabridge is probably the best. I have a few of these myself. How are you saying that you need longer cables? Mediabridge has a 10ft cable and you said you only need a 8ft one? Also, rapid charging is mostly a concern of the charger itself and not the cable (unless the cable quality is absolute crap).
Yeah it may be easy to find long cables, but it's not so easy to find ones that charge as well/fast as the short, authentic HTC ones. I'd also be interested in this - did anyone already buy and experience a quickly charging, long cable?

Placebo. Wires don't charge faster or slower. You might have a better connection or so with a gold plated connector, but it's no different if the wire is from china or if it's an authentic HTC one. There is LITERALLY no difference between the original HTC wire, the mediabridge 10ft wire, 6ft wire, or the coiled 2ft wire all of which I own at least when we're talking about charging time.

There is a difference. My eBay 6ft wire charges about 3-4x slower than the authentic HTC one. 8-9hrs vs 2-3hrs is no placebo.
My bad, I should clarify. There is no difference between real, quality usb wires. Like I said, you brought a crappy cable from eBay. You can google this if you're so inclined. There's no difference between two real usb cables. Also, "real" usb cables often have the usb certification logo on them.
Tldr; buy from a reputable seller that has good reviews. Should be little to no difference in charging.
Protip: Don't buy usb cables longer than 16ft
That's better - I didn't know there was such thing as USB certification. Basically don't trust eBay unless the product is genuine/expensive. Better off going to some big-name company like best buy.
Years ago people were wholly convinced that every and all cables are the same, which is just not true. Somehow some knock-off cables have some slow charging wires or whatever. Don't know how or why, but just a warning that if you buy some random cheap cable off eBay, it might not work nearly as well as a genuine product.

Technically speaking, it all depends on the materials they used and how the wires are enclosed. I would say most of the cables you see are indeed pretty much the same, but I generally do buy things from eBay. It could've just been a fluke. I haven't had to change or buy new usb cables in a while, but in no way would I recommend getting a big-name wire like monster or whatever from your local electronics shop. Amazon should be fine if you read the reviews.
I also recommend Monoprice.com's cables. Variety of cable lengths and great customer service. No point to risk and sift through random eBay or Amazon offerings.
Monoprice 10ft 28/28AWG cable. Using the stock HTC charger. No difference in charging time.

Never cheap out on chargers, been hearing shocking stories lol. Use the USB with the HTC adapter provided. I got a 10ft tangle-free micro USB and works great.

Some USB Cables, while charging (on the same Adapter) generates an note on the screen... that the charge is very slow...
in addition I tested a few USB cables that do charge...but do not transmit data properly...
the Original HTC that came with the phone is some how unique....

The original cable is not unique. It's just a normal microUSB cable. There are charging-only microUSB cables (often included in external battery chargers) and there are also badly-made cables, but the One's cable is nothing special.

Like I said, placebo. All certified wires that charge + usb transfer should have very minimal differences. You either get crappy cables, or you don't. The only problem I've ever had is the connectors falling apart. Never had a usb cable that charged my phone slower using the same adapter and I've had quite a few different cables from eBay, Amazon, etc.

You'd think people would realize why this is important. Imagine how many devices you would eventually kill with wires of varying draw.

People just like to see things that aren't there. Some people just want to convince themselves that the shiny gold plated, carbon fiber monster cables are worth the 5000% or whatever ridiculous markup.

Better check a 5pin USB cable vs a 4pin USB cable... that's probably your problem. I got that all the time with my crappy rosewill cable once that I bought from newegg.
4pin vs 5pin makes a huge difference... especially when an OEM charger is at 2mA rating

I have been having trouble recently with my galaxy s3 charging extremely slowly. Every since the OEM cable broke, I have tried to find replacements that charge at 1amp. The only cable that does this is the monoprice premium micro usb cable 6ft, but it breaks quite easily. I have also tried the 28awg 6ft monoprice cables, which were pathetic and charged at 100ma. This was all plugged into the OEM 1a wall charger fyi.
I have heard that the 24awg cables with ferrite core charges at a full 1 amp because the cables are thicker, but what I don't understand is that the OEM and premium monoprice cables both charge at 1100mah but are really thin compared to even the 28awg cable. The OEM and monoprice cables don't have specifications printed on them. I had always thought that generic usb cables were the same as OEM cables, and would charge at the same speed, unless there's something wrong with my micro usb port or phone.
I have tried looking for solutions but the answers on most forums are people asking why their phone charges slow when it is plugged into a usb port, and everyone just replies that the usb port output is limited to 500mah, but I am using the oem ac adapter and it's still slow. Only the premium monoprice cable charges full speed but its very poor in quality, the rubber cable separates from the plastic micro usb head, and it breaks. I have had 3 of these premium cables break in less than a weak and only 1 of them works, for now.
Is it my phone's micro usb port? I tried charging it using CM10.1 as well as Touchwiz 4.1.2, but they all charge slowly from the generic cables so it can't be the rom. I don't remember having any of these problems when I first bought the phone on ICS, and I don't see many posts on slow charging.
Is there a cheap, reliable cable that charges at a full 1 amp out there? Most people I've seen had suggested monoprice cables but their 6 foot micro usb cables have changed recently and are really, really bad. I guess the ferrite core cable might work, but I have yet to try it, and I am not fond of the idea of a thick 24awg cable and a big ferrite core sticking out of my phone.
First of all, do you have Galaxy Charging current app? https://play.google.com/store/apps/details?id=com.abmantis.galaxychargingcurrent.free - I think it's free for N2 and S4, but you have to pay $0.99 for S3 (I use it for free on my N2, but a buddy of mine had to pay to use it on his S3). That app will give you an idea of what's going on. You can also check out Charging Doctor I reviewed here: http://forum.xda-developers.com/showthread.php?t=2451375
Second, charging speed is a combination of both a charger and a cable. The only way to guarantee full 1A/2A output without high resistance which contributes to a drop of charging speed is to use thick wired cables like 24AWG as you correctly pointed out. But with wall chargers - just because they state 1A you will NOT actually get 1A due to efficiency losses. You know how your charger gets warm? That due to AC/DC conversion inefficiency which results in drop of speed and release of energy in a form of a heat. I personally don't trust labels on cheap chargers and also over the time even an efficiency of a trusted converter will go down. I have reviewed a lot of Anker batteries and chargers (check out review link in my signature), and those are the one I highly recommend.
What I would recommend getting one of these trusted 2A chargers and use 24AWG cable and check it with Charging Current app. If you are still seeing a very slow charging speed it means your micro usb connector is wearing off or loosing a contact with a main printed wiring board (pwb) inside of the phone.
I bought Blitzwolf 3A USB-C cable which I am using in my car with Android Auto & my HTC 10.
While I am switching to 1+3t I am thinking if I can still use same cable for Android Auto+charging in car
Any ideas?
The cable should be fine, but it will be trickle charge. Only the dash chargers provide quick charging.
I got this one for $6 on Amazon and it's Benson approved. I also brought a few Otium adapters, which sell a pair for $7 and of course Benson approved. They are so small, so I just have them all over the place. One in a bag, one in the bedroom, one in the car, and one in the office. If anyone found a good Benson approved USB-C cables that sell in packs with at least one 6ft, please share.
I bought a pack of these: https://www.amazon.com/AUKEY-Adapter-Type-C-MacBook-Google/dp/B01ANLA6OU/ref=sr_1_5?ie=UTF8&qid=1480436320&sr=8-5&keywords=usb+b+to+c+adapter which work ok and I didn't have to buy all new cables, at least for now. I will eventually get a new cable though.

These allowed you to trickle-charge via standard microUSB, correct? I have a 3T on the way, and I don't look forward to being chained to one charging cable.

Yes, they work fine. Description states it also has a 56kOhm resistor to prevent damage, but I don't really have any way of testing. I generally only use it as a backup at this point.

I had a Oneplus One and the only thing that broke on it was the charging cable, so being tied to one cable gives me pause.
Always go for high-quality well known and reviewed usb-c cable's. As dash charge uses 4 Amps+ you will definitely need a high gauge cable (thicker copper wires) to safely carry that amount of current. Tell tail signs of cheap cables are obviously slow charging but the worse case is a buildup of heat and short out of the cables. Braided also tend to have higher wear and fraying resistance. I went for one of these Anker PowerLine+ USB-C to USB

Yeah I just got one of these but Dash charging doesn't work. Might buy an extra from oneplus and reverse engineer and make my own.
I did discover the 1+3T slurps 1.5A (voltage drops to 4.6V)out of my desktop-PC USB2.0 socket when no data-connection is provided, and nicely reduces the current to 495 mA when connected to USB.
This with original dash-cable and Legion meter. I did not try for long though, as my mainboard is only rated for 1A.
From a good high current (IKEA) 3 x 2.1 A adapter it also takes 1.5A, with no voltage drop. So it looks to me that the phone is charging with 1.5A unless a dashcharger is directly connected, or reduced to 0.5 A when connected to USB.
When connected through my Legion meter, it will charge with 1.5A even if connected to a dash-charger.
From the cable-tables, you can select AWG 23 for 4.7A, AWG 27 for 1.7A and AWG 32 for 0.53A, so there is quite a difference

If you want to be able to quick charge you will be tied down to the stock cable. I have an abundance of USB-C cables that I used to use with my Nexus 5X (charged at 2.3A on average) and none of those cable come close to charging the OP3T at 4A. I usually get around 1.4A when using 3rd party cables.
Gor this one in AliExpress, dash working and fast delivery to Spain https://es.aliexpress.com/item/100-...-Flash-Charging-USB-Wire-For/32708785156.html
I bought this before 3 months https://www.aliexpress.com/item/Ori...32695530105.html?spm=2114.13010608.0.0.nTY2Iz support dash
Also seeing about 1.5a while using high quality cables and powerful charger...tested using Ampere. Just glad that this is my first android phone that I don't need to charge throughout the day.
Previous phones: mytouch4g, s2, note 3, note 4, note 5.... Never really put the 6p through its paces.

Yes, my first time with USB-C connector.
1. important change in my first answer - change "mini" to "micro". (I keep confusing the 2 in my speak! I have tons of "A to micro" cables lying around to charge things like my cell phones etc. So I got and ordered adapters which go micro female to C male. I have no idea if they will be problematic.
2. been lazy so finally ordered a couple cables on ebay with description "USB-C 3.1 Type C Male to 3.0 Type A Male Sync Data Charger Fast Charging Cable" - the important thing for me being the 3.0 type A. Even though realistically, I believe we are only using 4 conductors on a regular-speed power charge or data xfer. But the high speed charge probably uses more, but that's a separate cable attached to the wall wart charger.
3. as to them frying things , i googled and found many many many reports about that one incident. I actually expected more. What you could do to minimize this is eyeball connectors before you plug them in, and possibly shut phone off (and unplug charger) and plug C connector in to phone just to make sure it slides in easily. I believe the only USB connectors I have ever had problems with were very recent: micro male attached to the end of some cheap 10-20$ "endoscopes". Really had problem getting them in to my Moto G3, but no shorts.
Lightening can strike anywhere and anytime. We can just do our best to be careful!
Certainly I'll let you know my experience though I have yet to see the phone hit the post office.

I have not do very thorough reading, but from what I gather, the issue with USB-C is the potential for USB-C device (maybe 3 amps) to pull more current than the USB-A port can supply (most likely 2 amps), thus frying the USB-A port
A USB-C to USB-A cable that has 56 ohm resistor will avoid this issue by forcing the client (usb C device) to draw as much power as the host (usb A port) can supply

Thanks for this. A close read of that indicates to me that there is going to be a ton of arguing over what is safe, and some burnt out 5v power rails in some, especially older, computers.
The mention of 56Kohm resister in cables has caused some cable sellers to advertise that, but having that, in and of itself, I believe doesn't do anything - you need load balancing circuitry in both the phone AND the charger to utilize it.
I read this quote with amusement "A good cable uses a deep-draw extrusion method that produces a Type C plug that is a single piece of metal and does not have a visible seam on one side of the plug,". My phone came with a factory Motorola hi speed charger that is rated for 5v 3a (15w), and it's C plug has just such a "bad" seam. So many people make such blanket statements that simply are not true.
I looked at one of my wall-wart chargers(this particular one is stamped Samsung) and it is rated at 5v, 0.7a (3.5w), so it's a good bet that if I plug my old A to micro to micro-to-C adapter to phone, that nothing bad will happen. Another one (Moto) rated at .8a. A 3rd one that came with my Moto G3 is rated .55a .
1)So if one goes to ebay and buys a wall wart rated at 5a and uses old cables and adapter to plug it to a Moto Z, what will happen? Dunno!
2) I have had my Moto z plugged very often to my computer with just such an arrangement and have not noticed any "fast charging".
I have a huge 850w PSU in my computer, but that does not mean that all that amperage available on the rail is permitted through the USB connection. Intel offers some ideas and I would bet that most current mobos have such limiting circuitry: I am sure older (than 10 yrs?) do not, or at least not as effective.

The phone also has smart limiting circuitry, but of course I don't know what it is.
Am I more in jeopardy with an old A to micro cable with C adapter, or a new A to C cable. Dunno. Certainly any wall wart should be from the/a phone mfgr, or rated below an amp or so. I don't know if you can make this phone fast charge for 30 min if it's rated for 3a, without an official charger. The remainder of the charge time is governed by the phone to be at a much slower rate.
With this new phone, I have yet to connect it to a wall wart other than for 5 min to the official one just to make sure it worked, and I don't recall any high speed message. It winds up getting a 100% charge just by being plugged into my computer since I am doing file transfers and the like.
As to the plugs themselves, you can run much more amperage through an A (few wide conductors) than a C (many very thin conductors).
A very great deal is being made of this one incident. It is hard for me to understand how a different cable can burn out a computer. You can run 10 amps through any cable (though it will get more than a tad warm!), but amps in a cable is not a problem. It's the governor, or lack thereof, in the source (wall wart or computer) and the target (phone or another computer). If the computer presents a short circuit to the cable, something will surely fry, but no device, these days, should ever do that.
A cable (they all are made in China, but there are many factorys there with widely varying QC), with an M stamp on it or not, is still just 4 wires in a sheath. If it is poorly made, or the connectors at the ends are poorly made or poorly attached, there will be trouble.
Okay, that's enough words for this post, but, for sure, this topic will be around forever!
EDIT: C type connectors have been in use on phones for years now. Why have we not heard of any phones destroyed???????

Thanks for this. A close read of that indicates to me that there is going to be a ton of arguing over what is safe, and some burnt out 5v power rails in some, especially older, computers.

Certainly a good read, and another perspective on this matter!
I can't argue with anything you said
I am also in no position to offer any additional opinion, since I don't know squat on this topic. My first USB C device
But you do touch on an excellent point: not a whole lot of reported issue with damage related to USB C.
As statistics goes, 1 sample is not representitive
It is a data point, and that's a fact, but you can't draw solid conclusion from 1 incident

On the other hand I will try to get a 4-5' cable that supposedly has 56Kohm resisters in it...

Actually for possible protection of my old wall warts. If I understand correctly, using a 56Kohm cable keeps current low (slow charge). I'd hate to think what my wall wart would look like it my Moto z tried to pull 3 amps out of it!!!
EDIT - It also just seems a prudent thing to do...
Do you have any preferences?
I just ordered these on ebay: "USB C Cable (2-Pack 6ft) Anker PowerLine USB C to USB 3.0 Cable with 56k Ohm Pul"
