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"
regards

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).

charging rapidly with aukey quickcharge 2.0 wall charger and type c adapter

so this combo is working for me:
http://www.amazon.com/gp/product/B010UT6Z3Q?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s01
http://www.amazon.com/gp/product/B00W98IQ5M?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s00
the latter also allowed me to fastboot oem unlock.
so battery is at 59%, homescreen says 14 minutes till full.
cheers

can you please check with Ampere or GSAM for the charging speeds that you achieve?
does the device say fast/rapid charging?

Interested to hear the results from Ampere or GSAM as well

i cant get a good handle on how ampere works. it keeps measuring, takes forever, and fluctuates a lot.
with the aukey combo, i got 1830/2050mA @ 4.14v, at 53%, 37.7c
took it off charge for a while and tried again with the stock charger:
with the stock charger, i got 1850/1860mA(min/max) @ 4.159Vat 61%, 30.7c
I will try again at 50% today if I have time but I am pretty pleased with my little aukey combo. It was cheap.. I got it when there was a 7 dollar coupon floating around.

Yep that would be the one. charging at 1800mA is not the fastest that the phone can charge at though. I'm going to hold off for the ones that enable the full speed of charging

For 7 bux I think it's still a good deal for someone who doesnt have a spare to use

From the product description, you are only going to get 2A out of the charger. 5X doesn't do QC2.0, so you will only get the output at 5V, which for this charger is 2 amps.
Specifications:
Input: AC 100-240V
Output: 5V/2A, 9V/2A, 12V/1.5A
Dimensions2.69*2.05*0.87in)(68.5*52*22mm)

But some Aukey chargers with AIPowertech like this one "charges all non-Quick ChargeTM 2.0 phones and tablets at their normal speed (up to 5 volts / 2.4A Max)with AIPower Tech Technology."
I've got the charger, just not the cables... so haven't been able to test.

I tested Aukey PA-T2 wall charger QC2.0 port ( orange one) on a Sony Xperia Z3 compact tablet
I recorded charging current up to 2.7Amp with the Aukey USB cable and up to 3.0 Amp with the Sony USB cable !!!! far more than the 2.0 Amp level current Aukey specifies......
The voltage - current output test show that the voltage stay in the 9.0V range with current up to 2.4Amp then fall down very quickly. It seems that the voltage stay at a value enough to deliver up to 3.0 Amp charging current to the tablet ....
Detailed test are here (http://78michel.unblog.fr/?p=860 in french....)
Current values where obtained from BMW recordings

LOL, thanks... but that doesn't really help this 5X cause. Given that there is no quick charge on the 5X, it'll remain at 5V. The question is whether it'll pull more than the 2A or 2.4A specified on these chargers at 5V on a 5X.

Aukey quick charge 2.0 behave like a standard charger when connected to a non QC2.0 compatible device. The output voltage will stay to 5V so the current level will be very sensitive to the quality of the USB cable and limited by the maximum current the device will afford.
In practice it is very difficult to reach 2A charging level ( even if the charger is able to deliver such current) with a voltage output of only 5V , due to losses in cables and connectors
From my experience the higher current charging level I obtained was with a Samsung wall charger refence EP-TA10EWE which deliver an output voltage of up to 5.5V at 1.9A ( nominal voltage is claimed at 5.3V)
I got 1.7Amp charging current on my Nexus 5 while with the Aukey QC2.0 the current was only 1.1 Amp in exactly same conditions ( these recorded data are also reported in my blog .....in French.....)

Thanks, didn't think to look at the link.
I wonder how older phones like the NA Galaxy S3 and Nexus 4 that both have QC1.0 ([email protected]) compare to the charging of the Nexus 5.
I'm curious as to how you did your testing, as I'm going to try my own testing once my cables come in. Did you drain all your phone's battery to 0 before performing each test? Phone airplane mode vs off? I also think that all tests must be done in relation to time, especially since the charging profile changes as the phone charges. I'm also curious as to how the non QC port on the Aukey performs, since it's spec'd at 2.4A @ 5V.

All tests are made with battery drained to zero before starting , and a complete charge is done in each conditions. That way I can check that the full charging time is logically related to the recorded current values. The current is recorded during the complete cycle at a frequency of one value per mn.
The air plane mode was off.
Aukey QC port and non QC port are slighly differents when connected to non QC2.0 devices :
QC port delivers 5.1V in open circuit, the voltage encrease to 5.2V at 2.2Amp, on the contrary the non QC port delivers 5.2V in open circuit and decrease to 5.1V at 2.2Amp. I did not test them at higher current level.
I did not tested Galxy S3 or Nexus4 , but I beleive that a charger like the Samsung EP-TA10EWE will deliver them the maximum charging current they are programmed to accept, as obeserved for the Nexus 5.
I got the same charging current curve I recorded with Nexus 5 and Samsung EP-TA10EWE, with other set of charger and cable. This means that this charging curve is defined by the Nexus 5 inner program , not the charger characteristics. The problem is that we never know which is the max current curve internally programmed for each smartphone...... so it could be a long way to find it.......

Official Xiaomi"s super fast 27 w charger

its a QC 3 certified charger and A2 supports QC 4+ right?
so wether it takes 9v 2a (18w) or 9v 3a (27w) to charge
https://store.mi.com/in/item/3192900008
and also want to know is it safe to use moto's turbo charger because its output is max 15w

In general terms, V×A = W. Now, voltage is pushed and current is pulled. So it doesn't matter what the Amp is, what matters is that the Voltage should not exceed the max specs. That is why Oppo's VOOC chargers are best suited. They keep volt at 5V while increasing the ampere to 3/4 Amp to increase Watt without damaging the phone.

Qualcomm's quick charge technology is backward compatible. So a QC4+ supporting device will happily work with a QC 3 charger.
Also, QC 4+ technology is design to withstand upto 20v and upto 4.6Amps (not at the same time) and at the same time QC 4 and 4+ are no different the specifications there are same there is only some internal changes.
QC 4 achieves 27w not via the QC technology but it uses USB-PD which is a universal technology released on 2012 and unlike QC it's not proprietary Qualcomm's tech. USB-PD for our device works in the range of 3-11V and 0-3A.
Also, charging current and voltage is controlled by the device, not the charger. You can safely charge your phone using a MacBook charger which can provide upto 60w of power and it won't harm your phone.
#tldr : yes it's totally safe to use any charger with your phone. Unless it's not a cheap one which doesn't comply to basic quality standards you are good to go.

Hello
Can i use the samaung 9v 1.5A for my xiaomi mi a2 because phone came with 5V 2A , can this samsung original charger damage my phone ?

Using Power Delivery (USB type C to USB type C, 18w) charging

Hi guys, can we use 18w Power Delivery charging (USB type C to USB type C) on our Galaxy Note 9? As far as I know (read in GSMArena), Galaxy Note 9 only supports up to 15w charging.
Thanks

Yes, you can... but using usb type c it will not fast charge the N9 i.e the voltage stays at 5V and does not increase to 9V, although the current can go beyond the stock 1.67A.. close to 2A using some cables.
PD power adapters are the future due to universal compatibility. For example, I have one 60W PD power supply with an additional QC3.0 port; this allows me to charge my laptop at full stock speed and my N9 at full fast charge mode using the QC3.0 port.

Great! That means the PD will adapt to the N9's maximum voltage and current. I was just afraid it could mess up my N9. Thanks for the info!

I'm returning to Texas Thursday from an international business trip; will order one when I get back.
Thanks,
Joe

I purchased it and have been playing with it.
1) It is small. Fit in the palm of you hand small. Easy slip into a pocket while travelling small. Similar form factor to the old Samsung lightning chargers -- they are rectangular while it is square, but similar volume.
2) I don't see that it is faster than my existing 65W PD/PPS. Both give a max of 7.2A @ 4.1V -- but it could be cable limited. I have three supposed 100W / 5A cables. If you add 1A for the discharging load (Ampere reports 1A is discharging when unplugged), it's providing ~ 34W. But that's using Ampere which tells me what the state of the battery is, not what the actual current/voltage from the power supply is.
Overall, I'm a little real-life disappointed that I don't seem to be seeing 45W charging, but think it is worth the $30. If you have 30 min between flights, it can definitely top off an empty tablet battery.
Take care,
Joe

So I've been on several flights with this small charger. It is now my go-to for travel. What I like is that it charges the tablet so fast I don't feel bad disconnecting and charging my phone or ear buds for awhile. It only takes a few minutes to top up the tablet battery back to full. And no problem running on 240V power.
