Hi, I just lost the charger of my Galaxy Note but I have a charger of my last Galaxy S2 which still works fine but it has only 0.7A output. I remember Galaxy Note comes with a 1A output charger.
So is it safe to charge my Note with that S2 charger which has lower output A?
Thank you guys!
The worst thing that could happen is that it'll charge slower. But there is no risk on charging with that charge.
It's completely safe. It may not charge as quickly, but it's okay. To my knowledge, you could even use a 2 Amp charger without issues if you wanted.

Hi! I have a Note 10.1 wich cames with an 2.0V charger (instead the N7000 1.0A charger), what could happen if i charge my phone with the 2.0A charger? Will it destroy my phone? Reduce the battery life or something? Futant55 compared the Note1' 1.0A vs the Note2' 2.0A in his N7100 and the 2.0 charged one hour faster than the 1.0A. Thanks!

it will charge the battery faster but in long term reduce the life of battery and may also damage the micro usb port.. they are made for certain voltage only..
Dont do it! I did just that, charging galaxy note n7000 using galaxy note n8000 (10.1) charger, its really fast at charging, very convenient just to bring one charger. After 2 month, my n7000 start to flicker whenever it drains under 20%. since I was using otterbox, never realised the battery is already buldging, even the battery door not holding to the case!.
Come to think of it, i think maybe my board is also faulty after using the n8000 charger,
Guys,
Is it safe to charge the gear (on cradle) with the Galaxy Note 3 charger - rather than using the charger gear was supplied with in the box?
There is a difference, Note 3 Charger is 5V, and Gear Charger is 4.5V.
Its headache to carry both chargers when im travelling...
Thanks!

my gear charger is in my computer usb
so there is no difference really, the internal componants in the gear and note3 change the voltage to 3.7 volts anyway
usb is a standard and should be 5volts, or between 4.5 and 5

I haven't tried it but have read that higher amperage chargers like the Note 3's don't charge the Gear 2. Devices only pull as much amperage as they need so I don't think it will hurt. You might want to wait for an expert to chime in though.
Its the amperage you have to be concerned with. Most, if not all of the newer devices these days have smart sensors built-in, so higher amperage will not be an issue, the gear cradle will only pull what is needed.
If the charger cannot meet the specified amperage, ie lower amperage, the device will charge much slower, but it will still charge.
The voltage is not that big of a concern, most chargers have anywhere between 4-5V specification.
devices only take what they need *laymens*
devices only draw as much current as they need
a 315mA battery will not draw 5A of current
im a electronic engineer
Thanks a lot for your feedback guys!
I've tried to use my samsung 2.0amp charger and the watch won't charge. I have to use 1 amp charger or lower to work

I charge my gear 2 using my note 3 charger. Works a dream. Like was said before the battery on the gear will only pull what it needs.

has anyone noticed that the note 4 charges in about 1 hr to 1.5 hours max to fully charged? i have or is something up for it charging so fast?
Standard feature on the Note 4. If u look ad the adapter it's putting out 9 volts.

do you think we will see problems in future with batteries needing to be replaced sooner because of this fast charging
I turned off my fast charging option.
Yean I appreciate the superb fast charging. Is it bad to use my older note3 chargers as spares on the go?

It's not bad at all, you can still use any cell phone charger to charge the Note 4
just like we have done when we had the Note 3.
The thing I am wondering about is if can safely use the new Note 4 wall charger
to charge other peripherals like mice, keyboards, wireless headsets and so on.
I used to use the samsung S3, S4 and note 3's wall charger to charge lot's of things.

The batteries are chipped. Phones are chipped. And even the adapter has a chip. You can use your note 4 charger to charge any device. It just won't give the full output as other devices will tell it not to. etc.etc.
Thread moved to Q&A where it should have been posted originally - please post in the correct sections, thanks.
Hi there guys, today a friend of mine will bring me my Galaxy Tab S2 that she bought for me. What would be the recomended first charge time for this? I've tried to find that info in Google but no luck at all.
Don't know if the battery effect/memory effect affect this Li-Ion batteries and if I have to leave it charging long after getting the "%100" battery charge or just unplug it right there...
i left mine on to drain it completely, and it took between 4 to 5 hours to charge to 100% while turned off, using the stock Samsung 5V 2A charger.

Thanks for the post. Finally I got it to %30~40 and left it charging up turned on but with wifi off with the stock charger connected to the wall.

This is not required or advised with modern batteries and devices.

Now I have a doubt. I've the original charger and one original charger from a Samsung Galaxy 3 I think.
Tab S2 Charger
Input: 100-240v
Frequency: 50-60Hz 0.35A
Output: 5.0v = 2.0A
Galaxy S3 Charger
Input: 100-240v
Frequency: 50-60Hz 0.15A
Output: 5.0v = 1.0A
According to what I've read, you can use another charger that gives the same or less output but it can't have more. In this case the amperes are less so it will take more time to charge, right?
I'm asking this cause this to know if it's safe to use this other original Samsung charger or not.
You can use any charger with it. The Tab S2 only supports up to 2A so it won't take more than that. I tried charging the tablet with my Nexus 6 QC 2.0 charger and it performed the same as the stock 2A Samsung charger. If you use a 1A charger, it will work fine but it will take twice as much to charge.

As far as I know it's not recommended to use charger with more output voltage than the original. For example I've a Galaxy Note 3 and the Output is 5.3v instead of the 5.0v of the Tab S2 charger. That can cause trouble according to what I've read.
There are many things that are not recommended. That doesn't mean they won't work or that can cause damage or problems. It's just a recommendation. Like I said, I have used several different chargers, and they all work just fine, as long as they are 5V/2A. All genuine "Turbo" chargers scale back to the usual 5V/2A if the device doesn't support Turbo charging, which is why the Nexus 6 charger (and any QC 2.0 charger) works with the Tab S2.
If you use a charger and/or cable combination that outputs 500 mA or 1 A, it will display an X in the battery icon in the status bar and it will charge very slowly, or not at all if it's turned on and in use. For example, the micro USB cable that comes with the Google Chromecast has a resistor that caps the power passed thru the cable to less than 5V/1A so that cable won't work, regardless of it being connected to a 5V/2A charger.

The idea, regardless that if it charges slower than the original, is that the other charger doesn't cause trouble nor damage in the tablet. The Samsung S3 original charger 5V/1A will only charge slow but won't cause trouble, right? The Galaxy Note 3 with 5.3V could cause trouble/damage.
S2 must be different to the Tab S then as I've been using my chromecast charger and cable and a 700ma Samsung charger for the past 12 months no problem, admittedly usually when it's turned off.
I have no bones about using whatever charger I have to hand as long as it's 5v or thereabouts.

You'd be hard pressed to find a charger that outputs it's exact specifications. The circuitry in modern devices can handle these slight differences as it's an expected tolerance.

Didn't know that modern tablets could handle those differences between 5V to 5.3V. And to be honest and didn't want to take chances so I preferred to ask here.
The good thing is that I've now two chargers in case of need.
Thank guys!
The Chromecast charger and/or cable will work with the tablet. It will just charge a lot slower, and if the tablet is powered on and being used while charging, it will actually be discharging because the charger won't charge the tablet because it will be draining more power that it's receiving.
The 5.3V or 5.1V it's more or less not important here, as the tablet won't accept a charge higher than that and tolerances, etc... And if we're talking about branded chargers, those are usually good with their specs and can scale down accordingly. Cheap, non-branded ones are usually OK but your mileage may vary.

Can you help me with some other doubt that I have? My version doesn't have IMEI, that's normal right? Only LTE has IMEI?
I bought a HEYMIX 45W GaN PD Wall Charger, 30W USB C Fast Charger, Max48W Dual-Port Quick Charger AU Plug, Compatible with Galaxy S21/S20/10, iPhone 13/12 Pro Ma (thats a mouthful) for this tablet but i have an annoying issue since I started using it. I have constant popups showing the charge %
I have tried a couple different cords. I thought it might have been Gauge Battery Widget so I installed Battery Reborn and no difference
Is there anyone else with this issue that can help please.
Many thanks in advance
Same thing used to happen to me on my Tab S7+ when connecting to a non Samsung charger. Try the original charger or a high wattage charger. On my Tab S8 Ultra I have no issues when charging with a 65watt Oneplus charger.

To clarify - there is no "original charger". Samsung doesn't include chargers anymore. I suppose you could mean one that Samsung sells that's aimed at using with this tablet, but wow they're expensive and limited (one USB-C port) for what they are. Looks like Samsung is out of stock of both colors - no idea if you can find them elsewhere.
I haven't been actively using my Tab S8 Ultra enough at the same time as charging it so I don't know if I would experience the same thing. I do have the recent Anker 3-port 100-watt charger for when I have to charge fast (at 45-watts), but I haven't had a need to do that yet.
Thanks for that, the company I bought my charger from sent out a 65w charger and it works great
