Anyone know the actual amp rating of the charger for the Note 10.1? I know it's higher than 1.0, but I haven't been able to find the info online and I don't have my cable with me.
It's a 2 Ampere charger to the note.
2 amps, and the tab must see approximately 1.2 volts on D+ and D- or it won't charge.
As a result, 2.1amp iPad chargers will NOT work without modifications.

I have both a Nexus One and a Kindle Fire. Both devices use Micro USB for charging and I'm currently using the wall chargers that have come with each respective device. The Nexus One's charger has an output of 5V, 1.0A. The Kindle Fire's charger has an output of 5V, 1.8A. Is it safe to mix and match these device's chargers? The higher current rating of the Kindle Fire's charger won't kill the Nexus One, will it? Furthermore, I've been looking into a single charger that will be able to charge both devices. I've been looking into a charger that has a 5V, 2.0A output. Will this charger be safe for both devices?
Thanks.
I have used my HP Touchpad's charger which is 5V 2A output on my phone and it charges it just fine without damaging it. I think the phones regulate the charge going into them and it doesn't actually take in the full 2A.
Being an Electronics Engineer i can confirm, It is safe to use, . the current consumption within the amp ratings (max it can supply) of charger is the basic funda.and you can connect if you have 10A rating charger too..but remember the voltage should be 5V only. its must
I concur, don't wanna let the magic blue smoke out:-o
P.S. get a wall charger, they're grrreat!
Thanks everybody!
Can I use an Apple iPad charger to charge my Samsung Galaxy S3 Mini (GT-I8190)?
Input: 100 - 240V ~ 0.5A (0,5A) 50 - 60 Hz
Output: 5.2V ⎓ 2.4A
It is a genuine charger and I tested it for a few seconds, it charges, but it takes a few seconds for the phone to say "Charging" from when I plug it in. Should I be concerned? Also the output voltage is 0.2V higher than the normal 5.0V USB charging voltage. I know the amperage doesn't matter, I'm just concerned about the voltage and the compatibility of this Apple charger.
Any help will be greatly appreciated!
I use the same charger and i've been charging my Note 3 and Note 2 previously with it without any issues.
Thank you!
Thank you very much for your help!
Seems Qualcomm which charge 2.0 not working with Mi 4 original cable anyone suggest how enable fast charging on Xiaomi mi 4.
If I'm not mistaken, you need a charger with higher outputs then the standard wall charger shipped with most phones. Just a guess though seeing as my Xiaomi Mi 4 charger is a five volt charger.

My charger say Output 5v=2A/9v=1.2A/12v=1A i dont know if that whats needed but it charges very quickly.

5v is the voltage standard. What you want is AMPS. ALWAYS select 5 volts.
Computers (USB 2.0) can output maximum 0.5A (500ma) at 5 volts, while USB 3.0 can output 900ma or 0.9A.
Most MicroUSB chargers output anything from 1A to 3A+, with 1A and 2.1A being the most common.
So while a 1A will charge your phone a X percent per minute, a two amp charger will charge it at almost double the rate (not exactly, but close enough).
I do however (and I stand corrected), recommend not to go too high an amperage, while your phone my not get damaged, slow and steady charging is better for the battery than high current, quick charging.
Some phone, like my Galaxy S5, requires a 2A charger, but other phones may not like it.
I think it's always enable ...
Can we use this USB to fast charge our Note ?

It's a charger that will charge fast simply because of the high amperage. I believe, and trust me I could be wrong, the fast charging capability has to do with the plug's output. Your typical outlet plug is 5v, anywhere from 500mah - 2.x amp. The higher the amps, the faster the charge. If you look at the fast charging plug, you'll notice it's 5v 2.1amp OR 9 volt 1.67 amp. I believe the ability to fast charger comes from the higher voltage capability. So while the 2.4amp charge rate is good and will charge fast, it's not the fast charging like using the higher voltage Samsung plug.
Why do I get such wildly different charge currents into my tablet (Galaxy Tab Pro), depending which similar USB cable I choose?
The most extreme example is one that allows .28A to charge my tired tablet whether the cord is plugged into a wall wart or fast charger or basic linear 5 power supply. That same cord will pass 2.4A @ 4.9V from the fast charger into a resistor.
I gathered up all the USB charging cords I could find at home (8) and tested the current thru each when charging the tablet. Most passed a fraction of an Amp but 2 allowed nearly 2A.
I assume the tablet adjusts charge rate depending on something (I don't know what), so I repeated the test into a 20W rheostat, increasing the load until the volts drooped to 4.9V. On this test most of the same "wimpy" cords could pass over 2A.
What explains this difference in similar length USB-to-micro USB cords?
I started this test because my tablet wasn't 100% after an overnight charge.
