Is it Safe to charge Note 2 with other device's charger...?!?

My Note 2 charger says....
Input : 150-300 VAC 50-60Hz 0.35A
Output : 5.0V = 2.0A
Can i charge it with with following chargers....?
1. Note 1 Charger
Input : 100-240 V 50-60Hz 0.15A
Output : 5.0V = 1.0A
2. Iphone 3G Charger
Input : 100-240V 50-60Hz 0.15A
Output : 5V = 1A
3. Logitech Harmony Remote Charger
Input : 100-240V 50-60Hz 180mA
Output : 5V = 1A LPS
So can i Safely charge my Note 2 with any of the above chargers ? Or will charging with any charger Harm/Damage my Note 2's battery/internal components...?
Thanks.... :fingers-crossed:

As long as the Amper on the charger you use is lower than 2 there is no risk.
Voltage should always be the same or else it will damage your phone. (5volts = USB standard voltage)
If you use a 2,5 A charger the note will charge faster but will heat and damage the battery.
If you use a 1 A charger the note will charge twice slower than with the 2A charger but this charge will last longer because slower charging gives a little better battery life When I charge the note on USB 2.0 (0.5 A) / 3.0 is at 0,8 ampers it takes a whole night to get around 90% but my note lasts usually a little longer than when I fastcharge with the stock charger (one gets lazy to charge when a battery lasts so long lol...)

You can in theory use those other chargers but the charge time will be significantly slower, probably double the time. I used my nexus one charger which I use to charge everything in my room and I got an error message saying that I needed a stronger charger. You may get that message as well on those 1A chargers. I have been successfully been able to use my 1.8A blackberry charger with success though as well as my 1.5A griffin at work but I shorted the pins on the cable I use on that charger.
Like I said you can maybe use those other chargers but you may get a power message. You're best off with the stock charger.

use everything. "Just don't use LG chargers"

From what I understand through research, It doesn't matter at all. Stay around the official amp voltage range. If it is a bit high, the phone will regulate how much power it draws from the charger. If it is a bit lower, then expect slow charge.

Why not?

I am using a Galaxy S III charger, I guess I am not causing any harm with that... ?

You can use any charger that outputs at 5 volts. Even if the charger is 5 volts 10amps. The phone will only draw as mu current as its built to draw and no more than that.

Been using my s2 charger since I got my note 2 with no trouble at all. I also sometimes use my HTC desire charger and again no trouble here.

Hmm I thought changing the voltage makes the difference in how much power it draws (and puts into the battery) and the amp rating is how much power the charger is meant to give. So if the phone uses up 2 amps at 5 volts, then it could overheat a charger rated at 1A at 5 volts.
That's how powering something like LEDs works. If an LED is rated at drawing 700 ma at 3.3V, a power supply rated at 3.3V and 700 or higher will work - it could be rated at 2,000 at 3.3V and the LED would still draw 700. If you raised the voltage to 3.7V, then the LED would consume more than 700mA and would be brighter, if it's made to take the higher voltage.

This is correct. As long as you are using a standard USB charger, which will output 5v, you will be fine. The amperage will determine how fast your phone will charge. A charger with an output of 0.5A (500mAh) @ 5V, which is equal to 2.5 watts, will charge your phone slower than a 1A @ 5V (5 watt) charger.
No need to worry about hurting your phone with a higher amperage output. Your phone will only use as much current as it can handle. If it is rated to draw 900mAh @ 5V, doesn't matter if the charger can output 1A, 2A, or 5A, the phone will only draw a maximum 900mAh.

I bought some Palm microUSB charger during their liquidation. These days I dont even open the chargers for any phones I buy. Infuse, Xperia Ion, Focus, Exhibit, Note 1 all of them charge fine with it.

Hi
If the voltage output of a charger is less than 5V (let's say 4.5V), will this hurt the phone & battery?

Note 2 isn't that picky on charger.
I have several off-brand 5V 2-3A chargers and all of then just work fine.

Glad I'm not the only one using a random charger... The ones phones come with, the cords are entirely too short.

This is exactly what I am going to say.

Yes, its perfectly safe. I've used my iPad charger to charge my note 2 before, because it charges at 10 volts intsead of 5 so the phone charged faster.

I use whatever charger is available and fits. Have for YEARS. You guys worry too much about crap. It is just a phone, if it breaks, I'll buy a new one. Never had a problem though.

Using other device's charger is usually OK. But...
- An iPhone charger will work but because apple doesn't use the same standard to signal a USB charging port, you will be limited to 500mA (i.e. slow).
- Using another phone charger most of the time but because they are usally rated 1A instead of 2A it will charge slower.
The Note 2 seems to be quite picky about chargers and cables, for example, I couldn't get a full charge with cheap micro-USB cables from eBay and my old Nexus One charger. The best IMHO is a quality 5V charger that does at least 2A and follows the USB charging port convension of shorting D+ and D-.
More than 2A is not a problem because the device will only use as much as it needs. However if it is less, as the phone will try to pull 2A, the voltage will drop bellow the acceptable threshold. Usually the phone can adapt by charging slower but for some reason it didn't work with my Nexus One charger (1A).

any benefit using 2amp charger ?

Hi, im just wondering is there any benefit using a 2amp charger on the htc m8 , faster charging ? i know HTC are gonna release a faster charger which is 1.67amp , is it just the amp or it has some feature Quick Charge 2.0 built in you cant get with other chargers ?
the HTC One is rated to support Quick Charge 2.0 capable of accepting up to 60 watts of power – an increase of almost 100% compared to phones with Quick Charge 1.0. The 1.5amp charger bundled with the HTC One (M8), however, does not support Quick Charge 2.0. HTC is planning on releasing an optional 1.67amp charger accessory that will come with the technology later this year
Thanks

Yeah, it will charge a bit faster.

I've used the 2.0A charger that came with my Galaxy S4 and didn't really notice the phone heating up to unusual temps.

You can use a 10A charger if you have one (and it works with your power outlet), the phone should never draw more than the maximum it draws.

I originally used the charger I got with my M8, but then switched to a 2.5amp charger. According to GSam, my time to charge from around 80% to full is around 15 mins, but with the original charger, it was around 30 mins.
So from my experience, it does charge faster. From what I have read about QC2, the technology is in the processor in the phone. The charger can be any type, as long as it is able to deliver up to 60 watts.
See here - http://www.zdnet.com/qualcomms-quick-charge-2-0-offers-75-percent-faster-charging-7000026519/

The tech is actually in both the phone AND the wall charger:
From http://www.qualcomm.com/chipsets/quick-charge
"While Quick Charge 1.0 rests in the devices only, Quick Charge 2.0 resides in both the device, offered as a standalone IC solution or as part of the PMIC (power management integrated circuit) of Snapdragon™ 800 processors, and in the AC/DC wall charger."
The one you link is worded a little ambiguously:
"Qualcomm hopes to take things further by integrating Quick Charge 2.0 technology into standard micro-USB AC/DC wall chargers. These chargers will look and work like standard chargers, but will be able to deliver Quick Charge to compatible devices."
I tripped on it a couple times when reading it too, but it's implying that the tech does not currently reside in standard chargers, since they're still working on integrating it.

guess i will get the HTC fast charger when out and i bet we should get compatible quick charge 2.0 chargers too
Thanks

The amperage of the charger makes no difference, the device will only ever draw the power it requires to charge, no more. so a 5a charger would be no different to a 2a charger if the phone only draws 1.5a for example. find out what the device needs to charge and get as close as you can to that size for protection reasons

Yes, it will charge it faster. I used my 2amp charger and it did charge it faster. The phone may have some protection built in to protect the phones hardware. But the battery can handle much higher charge rates and the battery shouldn't start heating up till 20-30 amps. Yes, that's right.
I use Li-poly to race electric RC's and we charge them up to 50 amps. This charger will --->http://www.hobbyking.com/hobbyking/store/__46368__iCharger_308DUO_1300W_Dual_Channel_8s_Balance_Charger.html
Most people only charge at 5-10 amps, but to get peak performance, you will need to create a bit of heat and that doesn't happen till 20-30 amps.

Since I jumped from my old note 3tothe m8 I was able to keep the charger and it's a 2A one. Will I get the full 2.0 benefits with it or must I wait for the HTC one?

You will get whatever amp the M8 can take. i assume its 2A
I have a 2amp charger and i use it for my M8. i only see about a 30 min different from using a 1amp charger.

Its not just Amps, quickcharge 2.0 Also bumps up voltage. I tested multiple combinations with my htc one M8, here are my findings:
Quickcharge 2.0 18W Aukey (with regular micro usb cable): 9v/1.1A (~10w)
Quickcharge 2.0 18W Aukey (with data cut off cable): 5v/1.52A (~7.5w)
Wall 5v 2.4A charger: 5v/1.52A (~7.5w)
Stock 5v 1A charger: 5v/0.99A (~5w)
Car 5v 2A charger: 5v/1.3A (~6.5w)
some old 5v 700mA charger: 5v/0.7A (~3.5w)
MacBook Air USB port (2013) (with regular micro usb cable): 5v/500mA (~2.5w)
MacBook Air USB port (2013)(with data cut off cable): 5v/1A (~5w)
Ipad charger rated 5.2V/2.3A : 5v/1A (~5w) (no clue why its so sucky)
Also I noticed m8 once connected to charger (non Quickcharge 2.0) slowly increases charge current. if voltage drops below 4.92v it drops it back to these fixed values, whichever is immediate lower: 3oomA, 500mA, 700mA, 1A, 1.3A, 1.42A. 1.52A
these values are as per multimeters.
my car charger is tricky, it sometimes just falls to 1A instead of 1.3 as it border lines V to 4.92 while at 1.3Amps. (it is rated for 2.4A)

Car Charger For Nexus6

Hello,
I have the following charger in my car. Can I use it to charge my Nexus6 ?
It has 10 Watts per port, 2 X 2.1A, 5V (voltage not sure).
http://www.belkin.com/my/IWCatProductPage.process?Product_Id=652450
Please suggest.
Thanks.

Why do you think you couldn't use it?

I thought of checking with you, if the output of that belkin (current, voltage etc.) matches with the Nexus6. I understand that the phone will draw only the current that it needs (1.6A) from the charger. But not sure about the Voltage. It doesn't show the voltage in the specs also. So is the Nexus6 support all ranges of voltage - 5V, 9V and 12V ?
Please suggest.
Thanks.

Well if it is a standard USB connection on the charger and works with other devices, you can bet that it is 5v.

Yes, mostly. I have this charger with me and don't want to buy another one, and I have 2 phones to charge while travelling in the car.
One question: Whether the Nexus6 support all ranges of voltage - 5V, 9V and 12V ? I have seen them printed on the inner side of the Turbo Charger. But want to know more about how it works.
Thanks.

The 9V/12V on the standard charger are for Qualcomm's Quick Charge. The phone will charge from a standard computer USB port outputting 5V/500mA (albeit very slowly) if you wanted to. The phone will draw as much power as the charger can output for a given voltage, up to the limits programmed into the kernel for the charging chip. Either the charger or the phone could be the rate limiter, but any charger that you can have a microUSB connection to plug into the phone should work.

2.1A charger

Hey!
Is it OK to charge my nexus 5x with 2.1A wall charger?
Or it will damage my battery in the long term?

The ony problem is that it will most probably charge slower.

No it will not, the max Amps a USB A -> C connection can get is 2.4A, you're safe as long as your cable is compliant
Sent from my Nexus 5X using Tapatalk

Its fine, the nexus can't draw more than the charger can give, as long as the charger has the correct fail safes. Been charging mine with a old xperia 1.8 amp charger.
If it is a cheep wall charger don't bother trying, unless you have fire damage insurance.
If you're still not sure download ampere from the google store, get the pro version. After set it to display the current in the notification bar

Charging nexus 5x with 6p cable/wall charger

I got a new nexus 5x and I don't have the original wall charger.
I was thinking to charge it with the cable/wall charger that came with my 6p.
I was wandering weather it would be safe to charge with the 6p charger and if there are any differences between the two chargers.
Thanks.

They should be the same.

I am currently charging my 5x with my 6p charger with zero issues.

I had to borrow a coworker's 6P charger for my 5X and I charged to 100% w/ no issues.

I sold my 6p but kept the charger. used and compared it to the 5x's. they charge at pretty much the same rate. it just depends on thermal throttling and heat on how fast it charges. all good and nothing to worry if you ask me ☺

Look at the "what's in the box" in the Google store for the 5x and 6P. Both have the same 15W (5V/3A) charger listed.
There is no difference between the chargers.

So as long as the Watts, volts, amps are the same I can use any (non cheap) wall block? I have TONS of Samsung wall blocks and just bought 4 USB type c to a cords...still only have 1 wall block. Can I use the Samsung blocks?

Take a look at the article below. Yes, you can. However, it won't charge as quickly if it's a Samsung quickcharge charger. What really matters is that your cable is compliant. There has been enough talk on this board about that already.
Personally, I have four different chargers that I use. All work well.
1) The original one that came with the phone.
2) An old 1A charger from Samsung (non-quickcharge). Doesn't charge quickly. I use it over night.
3) A wall outlet with a 2A USB plug built in. Charges pretty quickly, but not as fast as the original charger, which puts out up to 3A.
4) iXCC dual usb 4.8A 24W car charger. Puts out 2.4A to each port and charges my phone almost as fast as the original charger.
