Can I charge NExus 7 with a 5V 1A charger ?

Bought my Nexus in the US this summer, really enjoy this little beast.
I have a question regarding charging. The provided charger is a 5V- 2A charger but a US one. I have at home a HTC one X charger which delivers 5V - 1A. Can I use this charger ? What is the difference between 1A & 2A ?
Thx, Yves

I don't see how less amps would hurt it. It may not register a charge, or charge very slowly. I would wait for another opinion.

2A will charge faster than the 1A charger. That's the only difference.

OK, thank you

On the flip side, can I use my N7 charger to charge my mobile (SG2)?
My SG2 charger is set for 0.7A, while the N7 charger is set at 2A.

Mine charges with the USB cable i use to transfer files, which is about 500mA. Works but slow.

checking around the net, that's what it say.
the USB port have a maximum of 500mA i believe. And i did noticed it tend to charge more slowly. While the provided Asus charger with USB port on it, it have 2000mA (or 2A). So i guess the Nexus 7 is made to be able to support up to 2000mA, while it will charge more slowly when connected to a computer's USB port.
I took out my PSP and its charger recently, and this charger is also 5V, 2000mA, except it's a round tip made to fit the PSP charging port.
I do have another 2000mA charger, it also have a round tip, luckily it fit on my Ainol Elf II tablet. I got this charger/power supply when i bought my HDMI switcher, it work without it, so it was sitting there for all this time, unused.
i'm gonna try charging it with the provided Asus charger now.

Yes. Your phone will not charge at the same rate as the N7, however.

[Q] Note 4 Car Charging?

Hey guys,
I just plugged my note 4 into my car charger (anker charger, oem note 4 cable) and couldn't get it to charge. It charges my note 3 no problem.
I also have no problems charging my note 4 with wall chargers.
Any help?

I've got the "Anker® 18W / 3.6A Car Charger with Built-in Micro USB Cord for Android" and it's actually CHARGING my Note 4 when using GPS navigation and playing music! My Note 2 wouldn't charge, but it would hold charge under the same conditions.
What model charger are you using?

I actually can't find it on the charger itself or even Amazon. It's relatively new, I thought it was a 2.0/2.1 amp charger (2x USB). Definitely Anker though.

Are you using both usb's at the same time? If so, it's splitting the power, so you'll get a slow charge.

Sorry, I should have specified - the only thing plugged into the charger is my Note 4.
Shoot, maybe I just need to grab another charger. Thought I made a good decision with that Anker.
Thanks for your reply by the way

If you get the one I listed, it works for sure. Great charger and it's been the only one my wife hasn't been able to destroy. :laugh:

Will the car charger also do the 50% in 30min charging ?

Doubt it. You need a special charger for that.

Hmm.. this mentions rapid charging, I wonder if it's as fast as the wall charger
http://www.samsung.com/us/mobile/cell-phones-accessories/ECA-U21CBEBXAR

The only chargers that work with the new fast charging technology are ones that are purpose built and have the ability to switch between 9V and 5V,they are quite uncommon.

I have this charger http://www.amazon.com/gp/product/B00D82O68Y/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
and it charges my note 4 while running Waze and tethering my Radar Detector via Bluetooth (which also uses GPS)....and it charges my wife's S5 at the same time

Using an afer market 2.1a charger and an S3 cable, charges just fine.

I believe Samsung has stated it's a 9v charger instead of the conventional 5v charger.

Did some more research and found this:
http://www.incipio.com/chargers/car-chargers/quick-charge-2-0-single-port-usb-charger.html#
From the Engadget review, "I clarified with Samsung that it chose a proprietary solution instead of licensing Qualcomm's QuickCharge tech, but it insisted that you could still use QuickCharge 2.0-compatible chargers to achieve the same results."

[FAQs] Smart Phone : Galaxy Note 4- To use fast charging, what kind of charger should be used?
Fast charging uses battery charging technology that charges the
battery faster by increasing the charging power. The Galaxy Note 4
device supports Samsung’s Adaptive Fast Charging feature and
Qualcomm Quick Charge 2.0.
To use Fast charging on your device, connect it to a battery charger
that supports Adaptive Fast Charging or Quick Charge 2.0.

USB type C to USB A fast charging?

Are USB type C to USB A cables capable of fast charging? Or is USB type C to USB type C the only way of getting fast charging?

You can get somewhat fast charging on an A to C cable theoretically, up to 2.4A, however as USB Type A isn't rated at 3A you won't get the full speed of a true Type C fast charger. I found with many Type A 2.4A chargers though that none say fast charging, but that may just be because I'm using the cable that came with my 6P.

I bought this cable and plugged it into a USB 3.0 port on my pc. It delivers just as much juice as the stock charger. The two both charge at the same rate.
Updated. I'll add that USB 3.0 is capable of delivering up to 5 amps with the right cable.

I have the Play store Google cables and they won't rapid charge with my car rapid charger , but the Type-C to Type-C google cables will with same charger . So I'm thinking no but I don't have a AC rapid charger to confirm .

A USB 3.0 port on a PC can only deliver up to 900mAh. The stock charger is 3000mAh.

That is a big difference in mAh. It does rapid charge pretty fast though when plugged into my pc. It did not rapid charge with the cable Google provided though. I had to buy the joto which I showed above.

Does your phone say rapid charging? What does Ampere show as the rate of charge?

Before the car was broken into I had a Belkin 4 port charger and the A-C cord delivered fast charging just fine, the one it came with AND the third party cord I ended up using also, have a couple of Yoozon branded cords from Amazon

I have a-c cable, and tried charge it using a 2.0a power bank. It says charging rapidly. Is it save to charge this phone using power bank?

Yes. It says rapid charging. I'm not home now but will check what it says it charges at. I did grab a screen shot yesterday though. You can see by "USB debugging connected" that I am in fact plugged into my pc and it says rapid charging.

Connected to pc I get Max 1050 mAh. On stock charger I get 1850 mAh Max. So the stock charger will be about 40% quicker than USB 3.0. Guess one could just buy a USB C 3.1 pci card if they need it as fast as the stock charger

The stock charger is 3000mAh, so depending on how low your battery is (it charges at a higher amperage at a lower battery, and slower as it gets close to full), you would likely see 2500-3000mAh when charging a nearly empty battery, which would be 3x faster than a computer USB port. I'm not sure why it says charging rapidly though, that should only happen if it's above 2000mAh or so.

Maybe an extra pin being present tricks it(wild guess). I did notice the fluctuations in mAh and am glad to know that's normal . One thing I noticed in the app ampere is it said the port was capable of delivering 1800 so maybe it's just reporting wrong in marshmallow.

Any issues with using Samsung USB C cables/chargers on V20?

With all the returns and obtaining of phones I've amassed a nice stockpile of Samsung fast chargers and a few Samsung USB C cables(and adapters).
I've read before that USB C allows for non standard use of cables by manufacturers so I'm wondering if anyone has tried or knows if it will be an issue using the said chargers/cables (yes I know the Samsung chargers are only QC 2.0 spec).
I have a QC 3.0 car charger I got from Aukey during a sale. I have some Aukey USB A to USB C cables too that work fine with my Note 7 too.
Trying to see if I need to slowly replace my Samsung chargers with official QC 3.0 wall chargers (will need at least 2)

Here at work I am using my Note 7 charger setup. Left LG flat cable at home.

Thanks for the reply, that puts me a bit at ease. I'll probably still get some QC 3.0 wall chargers but wait until I see a sale from Aukey for one.

Sorry. Side question.

It's adaptive fast charger and does either 5.0v @ 2A or 9.0v @ 1.67A so 10w or 15w respectively

All QC are backwards compatible. QC 3 will know you are using QC 2 and charge at the rate of QC 2. If you use a QC 3 charger and have a QC 2 device the device will only draw QC 2. So you have nothing to worry about as long as they are QC compliant

OK.... so i wanna know is it bad if i charge this phone with samsung adaptive charger ? and what about AUKEY USB-C Car Charger with 5V/3A USB C & Quick Charge 3.0?
My another problem is when i use oem charger my phone getting really hot like the back panel 110 degrees till almost 90% and then start cooling down, but i dont have this problem with samsung charger and my phone still charge pretty quick.
is anyone has the same situation?

The phone uses USB-C power delivery for charge spec. QC3 chargers don't work at all on my PH-1, seriously charges at .5amps. You're fine to use the Samsung charger or any other adaptive charger like Ankar power port chargers, they work fine.
Not sure about your phone getting hot using the stock charger though, mine doesn't do that.

So the phone will charge with an old USB Type-A charger and a Type-A to Type-C cable? What if it's not a QC3 charger like my Anker PowerDrive 2? I've read that some peoples phones charge slower than it uses power when using older chargers, but then some people say they charge ok, slower, but not that slow.

Yeah the power port chargers work just fine. Just not QC3 chargers, in my experience.
