I've googled it and I'm getting very mixed opinions. Most say 2.1 of course is faster for charging. I am led to believe that because even the box to there car chargers say the same.
I would like to disagree but need help understanding why. Maybe I'm wrong and I have a faulty charger.
My charger has two ports. One is 1amp and the other is 2.1amp. My 1amp side seems to actually charge my phone faster than the 2.1amp side. Also with 2.1amp while in listening to music through Bluetooth using GPS and navigation all at the same time, it tells me my phone is dying faster than it's able to charge. With the 1amp side I'm able to hold a steady charge sometimes going up at least 2 percent during a 30 minute drive.
What's your opinions? This isn't the iPhone or Samsung threads so I'm sure we have some of the smartest guys/girls here on xda

It should be a no brainer that a 2 amp charger will charge your phone faster as opposed to a 1 amp simply because one has more output than the other. But I believe that because of the smaller battery the phones have, they need a smaller amp per second of charge. If not then it may destabilize your battery.
Thats just my two cents though. Dont quote me

HTC put a limit on how fast the phone can charge. The chipset supports rapid charging but at what cost (of the battery)? So to be safe HTC disabled that feature of the chipset. So even if you plugged it into a 4 amp USB connector, you are not going charge any faster than say 1 amp. Don't know what the specifications are on the optimal amperage...

Using a higher amp charger cannot damage the battery. The phone will only pull as many amps from the charger as it needs (probably 1.5 amps max).

Htc one battery originally is charged by 5V and 1A charger; Can 5v. and 1.3 A damage the phone?
One thing that nobody here has mentioned is the possibility that your charger might have been wired wrong and the side that charges faster is actually the 2.1mah connection instead of 1mah.
With all of the chargers from everywhere in the world that we get them from and they are supplied from, anything can happen that We don't expect.
Maybe you might want to get it tested with an OHM Meter to verify which connector is the Higher and which is the Lower.

The only thing that is different (as far as the phone is concerned) is whether it sees an AC style charger or DC style. No matter what, the phone will only pull what the charging circuit "says" to pull.

For some chargers, sometimes the 2 Amp port appears to be using the Apple protocol for USB power, so that port will only provide 0.5 Amps to most other devices. And when the1 Amp port somewhat over delivers, and can source 2 Amps if nothing else is connected and 1.5 Amps if the 2 Amp port is sourcing 0.5 Amps for a non-Apple device. Thus some chargers can support one high power non-Apple device (in the 1 Amp port) and one lower power device (in the 2 Amp port). FYI I use this charger bought on Amazon---Avantek. Worked really well, versatile and low profile.

You can charge. It is the voltage that must match (and for USB it is standard and equal 5V) And the wattage of the supply(charger) should be greater or equal to the device's wattage.

i don't know about that. i just plugged in a 22,000 watt 5V supply. the phone exploded, blew out two windows of my house and the battery is still lodged in my ass. do you think i need to go to the ER?
If I use the power supply from HTC the touchscreen's response is bad. Drawing gestures on my lock screen doesn't work good. But I'm using if for over a year now, and had no problems. Guess it could be worse for my battery.
Shouldn't be too hard!

Play with it a while and see if things improve or get worse.
Were you using the OEM charger AND cable? The $1 chinese cable I used with the OEM charger had mine charging to 100% in 16 hours +
Make sure you are using the OEM Charger & Cable.
Also make sure you use the mains and not a USB port, I tried using a USB port on my mains and charging was like 1% per 30 mins, plugged it directly via the AC adapter in and started going up 1% per min.
I am using the charger that came with my Nexus One at the moment. It seems to work fine with all my other phones, does the N7 need more power or something?

It's not irrelevant. It means the 2A charger can source up to 2 amps if needed (which obviously it does need).
A tablet has a lot bigger battery and draws more current then a phone, which is why it has a bigger charger. If the charger can't source enough current to overcome the rate that the device uses power, then it won't charge or will take forever.

The stock 2A charger does it in about 3 hours and change from full drain power down to full charge.
Both of you are right, not the irrelevant part mind you but the part that it is enough and it may not be.
It all depends on what the tablet is doing at charging time. If it is off and the leakage current is low (as it should be) then most any 5v transformer will do. It will just take longer to charge.
HOWEVER if the transformer is not able to feed the N7 with more current than it needs to operate, on or off, sorry it won't work, no charging for you.
Now shake hands and go play outside.

No problem. I didn't mean to get snippy either, but I'm having a sh*tty day. ..To get back on topic, being an amateur radio operator, I have to have a little knowledge on electronic theory. My original response wasn't really to debate whether 1A is actually enough to charge an N7. My post to the OP was pointing out that he is in fact using a charger rated at half the amps of the rated charged of the N7, for whatever the reason it isn't working, and it also seems instead of trying the correct charger, he came directly in here.

The transformer is a source. It doesn't feed or force, it gives what is demanded by what it connected to it, as long as it's not over what it can handle (2A max rating) - in which case the coils of the transformer will get hot, possibly melting off the clear enamel insulation of the coils until you get a short and sparks flying out of your outlet, and pop a surge protector (hopefully)
edit: well unless it has some over_current protection built into it, or a fuse, in which case it would just die and not charge anymore :laugh:
edit2: But as just lou said, try the correct charger.
Another problem from using too low of a current transformer is you could put too much stress on it, and then it's voltage regulation circuits don't keep a nice clean steady voltage, and instead you could get spikes or noise, and that could lock up your device too. Of course this is just all possibilities, but to rule out variables it's just easier to use the correct charger
If the Nexus tablet requires 2 amps, then it will pull upto 2 amps. If it's doing this from a 1 amp supply, then the 1 amp power supply will overheat and possibly break. Amps can be larger than needed, but make sure voltage is correct.
Can someone tell me if the Htc One charger is the same as the One S please.

Careful. HTC does something funky with the wiring in their chargers and phones such that, when using a non HTC charger, the phone will only charge at 0.5 amp, vs 1 amp with an HTC charger. Net result is that your phone will take twice as long to charge with a non HTC charger. There are several threads on this subject, and I've observed it first hand on my One. The non HTC charger shouldn't hurt your phone though, only your patience...

I don't think the problem is at HTC but the charger you might have. I have successfully charge @ ~800mA (1000mA = 1 Amp)with different chargers ( Asus charger, Samsung charger and a newer palm charger). My new blackberry charger can charge @ ~600mA.
If I use my older palm charger, my Nokia charger, my old blackberry or a dollar store charger, it will only charge @ ~3xxmA.
If you read the spec carefully, you will see most newer *smartphone* charger max @ 1A, and older charger max @ 500mA. (or my BB charger max @ 800mA. )
So it's OK to use non HTC charger, just be sure to read the spec and find one charger =>1A.
Hope this help.

That is correct, usb specification is 5v, with 500mA (0.5A) maximum, hence the modified cable you refer to. The simplest way if you don't wish to modify cables is to buy HTC car charger

The charger *should* only provide 2A if the device (phone) request it.
Just thought I would chime in on some observations here. Long story short, when I bought my HTC One, I left the charger in the box and continued to use my multi-port USB charger with 3x1A ports and 1x2.1A port.
When connected to the 1A port, I found it quite strange that my phone was taking 4 hours or longer to fully charge. Also observed the same thing when connected to the 2.1A port. I was thinking that something was up with my phone somehow limiting the maximum charge current.
Anyway, I read a suggestion to use SystemPanel Lite to check for USB or AC power connected and sure enough it was reporting USB power. I remember the case with my Xperia X10 where you have to short out the two middle (data) pins on the cable or in the charger so that the phone detects that it is being connected to an actual charger. I tested it with my old Xperia charger, another generic USB charger, and the HTC charger and managed to get SystemPanel Lite to report it as AC connected.
But here is the interesting part. I have a car charger rated for 1A. Initially it never worked with the Xperia X10 until I opened it up and shorted out the two data pins. It has worked ever since. However, when I connect this to my HTC One, it still reports it as USB connected.
This has got me thinking that there maybe something more than just shorting out the two data pins for the HTC One to detect that an actual charger is connected. Just some food for thought.
Don't tell me HTC pulled an Apple and we have to buy only HTC chargers to get full speed charging? Does anyone have a confirmed non-HTC car charger that reports "AC" charging in SystemPanel Lite?

As per my post, I tested a generic USB 1A charger (it's at home, but it was one that was supplied with a Netcomm MyZone) and with my stock Sony Ericsson USB 700mA charger, both of which reported as AC connected. There has to be another way that these can be detected as chargers other than a simple short of the data pins.
Tested not to work so far has been an iPhone charger, Amacrox AX025-TACH1, Philips Power Bug, and two generic USB car chargers both with the data pins open then shorted.
Non HTC charger plugged into wall reports ac power. Proof

I am talking about all chargers in general. OEM chargers are better than the belkins, tankers and whatever. I read a couple very good articles about how good or bad chargers are. The ones that come with our electronics are usually the best. USB cables vary, sometimes even within the same models. The Samsung and apple chargers are really the best value when you consider longevity, heat, reliability and some other factors I am not qualified to explain.

for what it's worth the oem samsung galaxy note 2 charger is pretty fast for me a 2.1 amps. I even bought a second one to have for up stairs in my house.

I heard that. Gotta use a Samsung cable though to get the full benefit. Haven't found another cable that will let it charge full blast yet.

is it safe to charge with more than 2 amp ???
i dont think its safe

Yes perfectly safe.
Amps (current) are drawn/pulled, not pushed. More amps in a charger just means your phone can draw more without burning out the charger. It does not mean that the charger pumps out more than your phone can handle.
Volts are different. Too much or too liitle volts are harmful but all usb chargers are the same 5v so don't worry about that.
Lastly, unfortunately the different manufacturers have created different special schemes to trigger or allow devices to exceed 0.5 amps (to prevent a high draw device from trying to pull 2.0 amps out of a 0.5 amp usb port and burning out a usb port or possible even all usb ports on your expensive laptop!)
So, merely having a charger that says 2.1A on the side isn't enough by itself. You will still need to try differnt cables and try different models of chargers and even different kernels if you are rooted, or refer to reviews where the reviewer covered this explicitly instead of just saying "It worked great" which is a meaningless waste of everyone's time.
For instance there was another thread about chargers where they found that on a 2 port model that has one port labelled Apple and another labelled Android or just unlabelled, they found that they actually behaved different. The Apple port was 2.1A and the Android port was only 1.0 or 1.5A, yet a GN2 charged faster on the Android port. Because the GN2 didn't recognize the Apple port as being capable of high current, at least not with a standard cable, and so the GN2 was only pulling 500 or 700 ma, while on the Android port it pulled 1.0 or 1.5A.
So you really need reviews and testing that takes all this into account and specifies actual charging times and that make and model of the usb cable used etc. Or just buy the official stuff from Samsung which is all garanteed to match and work as expected without having to know all that unsuspected stuff.

I have quite a bit of cells and tablets, who doesn't, but I also have quite a few rc cars and helis. All the battery's we are using are Li-on although I use a ton of lipo (lithium polymer) on my rcs. Ive built packs, soldered connections, I charge 6 batteries in parallel, etc. I have a 530 watt adjustable 18 Volt 30 Amp PSU connected to a 400 watt 18 volt 20 amp balance charger. Granted if your not in the rc world this would be overkill for sure just to charge your cell battery. Point is you can charge any, repeat any Li-on or lipo battery at 1 C. . 1C is the capacity of the battery. All of my lipo rc battery's can be charged at 5C. That means 5 times the capacity of the battery. In our case the note 2 battery is 3100 mah or 3.1A for short hand notation. So if you have a big enough charger like I do, you can safely charge it at 3.1A in an hour. Some of my bigger packs are 6S 30C 10A packs. That is 22.2 volts 30C discharge rate and 10Amp or 10000 mah capacity and 5C charge rate. If your not familiar with the above jargon no matter, the OEM Samsung charger with the OEM usb cable that comes with it puts out 2.1 or 2100mah per hour or 2.1A . Our stock OEM batteries are 3100 mah or 3.1 A. So they will fully charge in about 1 1/2. Ive timed it several times and that is pretty accurate. This is with the phone being off not on while charging. It will take a little longer with the phone on while charging, about 2 hours. Hope this helps.

hi Joe , could you add some pics and diagrams . Thanks
Pics for what? Do you mean my lipo charger and PSU or the samsung oem charger? And diagrams for? Ill help, just not sure what exactly you want.
Using CM10.1 (06-14 nightly) on my One (International), connected to a Belkin 1A USB car charger with a decent quality USB cable. The phone discharges slowly in general use, and quickly when using GPS. Looking in battery settings it shows "Charging (AC)", which would suggest that it's drawing the full 1A for charging. I didn't notice this problem on stock Sense, although it's been a while since I used that.
Has anybody else seen anything similar on their One? Is there any useful information I could get from a logcat to give to the CM devs?
Thanks in advance,
Jon
OK I checked on stock and it does drain similarly. Should I just get a more powerful charger or could I have a hardware problem? Tried with 2 different 1A car adaptors.

Have you got a clamp meter or know someone who has one? That will tell you how many amps are going into your phone. It does sound like the charger though as your charger at home should be similar voltage/amps to the car charger only the AC charger needs a transformer and rectifier to step down the voltage and change it from AC to DC, car chargers just step down the voltage a little (12v-5v) so require little additional size. Probably easiest to swap out the charger, they're pretty cheap

I think you need a bigger charging maybe the charger is not able to provide the needed ampere.

Thanks guys. I've ordered a 3.6A charger which had reviews saying it worked well for high power usage Android devices. So hopefully that'll sort things out. I'll post back my results.
OK, tried with the new charger and a good USB cable, and all is well. Even with GPS and Spotify running together the phone still charges slowly.

It's probably not about the Amp rating of the charger. You probably had a cheap charger unit that couldn't deliver the amperage the phone needed either cos it was using cheap parts or something. A proper 1amp charger will still do as well as your new 3.6A charger

Yeah that makes sense. I just thought that if I got a massively over-specced charger then it would at least manage 1A Would have expected the Belkin one to work properly in the first place but never mind.
