charging note with 0.7A instead of 1.0A

I've got my note today and the charger has output 5V and 1.0A
My galaxy s charger has 5V and 0.7A
Can I charge the galaxy note with the galaxy s charger? I know it will take longer but beside the charging time is there any other downside? can i damage my battery?
thx for help
I think you might mess up your battery stats if you used the galaxy s one first, but i think if you do the first 5 chargers from flat to 100% to get them right no reason why you couldn't use the galaxy s one. After all usb charging is slightly less output than mains.
thx alex

I use my GS charger most of the time
I dont notice much difference in charging time.
ONLY charging time is the diffrence. most noticable if gameing, navigating or streaming music via 3G+bt at the same time.

POWERBANK for S7 EDGE with FAST ADAPTIVE CHARGING SPEED

Hi all,
I want to buy min 20000mAh capacity powerbank for me and my wife's S7 Edge phones and capable of fast charging both S7 Edges simultaneously.
I already bought Anker Powercore Elite 20000mAh ( https://www.anker.com/products/variant/PowerCore-Elite-20000mAh/A1273011 ) but, it does not charge them with fast charging !
I tried many cables (all of them orginal and official) but the results are the same: "cable charging" !
So, can anyone suggest me 20000+ powerbank with fast adaptive charging for S7 edge for sure, even better if real user with real experience?

Thanks. I checked it out but not enough for us :/
Also, it is surprising that Xiaomi can support fast charge for Samsung S7 Edge but Anker can't !
Mine was Anker Powercore Elite 20000 and had 3 usb output, total 6A. If 2 phones charge at the the same time, 3A for each.But still says "cable charging" :/
My orginal samsung fast travel adapter is 2.1A and says "fast charging"

Are u sure the Anker that u bought is fast charging support ? Try with different cables bro. I will check for a 20000 mah MI PB and give u link
Your Anker powerbank doesn't support fast charge.
Samsung fast charge work by increase voltage from 5V to 9V but lower current from 2.0A to 1.67A, which give the total power of 15W (9V×1.67A) up from 10W (5V×2.0A)
So for powerbank to support fast charge, it must be able to output 9V.

So if that is the case, is there any product or a brand that you can suggest with 20000mAh ?

Thanks for the advice.Yes i checked that out also and it supports quick charge only if 1 phone is charging.
But i decided to buy Xiaomi Mi ( 2nd Gen) Powerbank 20000 mAh. It has also QC 3.0 and almost half price cheaper. I read the comments about it and most of the users are happy.

Any one with Galaxy S8 Active, what is the charging rate in mA?

Hi all! I have a Galaxy S8 Active which runs T-Mo firmware and is used on T-Mo network. The phone has latest August patch installed. Could anyone please tell me what is the charging rate measured with Ampere or similar app? I don't have original charger and cable at the moment, but I do have compatible chargers such as Anker 5 port QC 3.0 and 1 port of with PD which is 3 Amp. I also tried Pixel 2 charger, another Microsoft 3.0 Amp charger. All of those chargers provide about 970mA which is the max I have seen. The rate doesn't go up. The lock screen shows as charging fast
It depends on the charger. I measured with a USB tester the charge rate with two SONY chragers and, while one charges at 0.9 A, the other one does it at 1.5 A.
The capacity of the battery seems to be 2400 mAh with a brand new one from 2017

Nexus 4 charging rates question.

Hi there. I was curious for those of us who still use a nexus 4
What charging rates do you get? The maximum i have ever gotten is 850mah via main wall socket with an official Qualcomm quick charge three one. even just a cheap charger i have around gives the same maximum charge limit
At 50 % charge it tells me an hour and a half to full. Its a long time
My cable is rated to 1500 as another phone hits 1350mah charge. With the same chargers
Please do let me know what you've gotten and if its more.
Also if any of you have exact quick charge 1 specifications, let me know. Or specifically how it works.
I used ampere to check. I know that fast charge is only for usb.
I use a 3rd party charger and Max charging current is ≈860mA

That seems about on par to what I've always had. I've seen mine hit 870. But not often. I guess thats just the maximum of qc 1.

Third Party Fast Chargers for S10+

Is it safe to charge Galaxy S10+ from a third party fast charger I was reading somewhere it's not recommended to charge Galaxy phones from any other chargers which is weird, can anyone confirm?

You can use it but must be same voltage and ampers its recommended. If you example use charger with higher voltage phone can't charge with that voltage and will be charged it with default voltage and ampers i personally use qc 3.0 charger with output 5A or 9A and with one usb port which have output 3.4A and i use usb TypeC cable wich have possibility share power with 3.4A

Can you please share the charging speed difference between the stock and Anker Charger...?

I dunno how to exactly measure it but as far as I am concerned its charging at a same speed the stock does.

Oddly enough... I have a Huawei Supercharger around (the 40w one) and it DOESNT fast charge my s10+

Exactly that's the thing with this fast charging phenomena you never know what will fast charge your phone especially Galaxy phones but finally I am glad I got Anker one :good:
