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.

How to know which chargers/cables are compatible?

I had an HTC Thunderbolt before I got the LG G2, so I had tons of $5 USB micro cables and wall/car chargers sitting around. Well apparently none of those cables are compatible with the G2 and when using the USB cable that came with the G2 with the car chargers I have(the $5 ones from Frys) it only "slow charges".
If I get some cheap cables/chargers from Frys or Amazon, how can I know in advance if it is compatible to allow the standard charging capabilities of the G2?
Thanks,
Craig

I'm getting the G2 in a couple of weeks and I have the generic T-Mobile car charger. I can only hope it works because it's the only one they sell.
eta-On the T-Mobile site it says it's compatible. I guess I will find out soon enough.

How much Current does your car carger supply? Most car chargers are around 0.5A. I think the G2 needs something like 2A in order not not "Slow Charge". The G2 has a fast charging rate.

I'm pretty sure it's a .5A.
BUT what about the cables? it wouldn't even work at all with any other cable besides the one that came with the G2.

It should be 5 volts, 2 amps.
From the AnandTech review:
The G2 can negotiate a 2A charge rate on my downstream charge port controller and charges very fast in that mode. Of course the PM8941 PMIC also includes some new features that Qualcomm has given QuickCharge 2.0 branding.

You should also be safe with chargers rated above 2A, as long as they are 5V. The device will only pull as many amps as it needs.

I think that only applies to Verizon phones. I think they do something to make other chargers not compatible. I have had that issue with different phones throughout time and everytime it was always a Verizon phone. Never have I had that problem with any other carriers phones. I could be wrong but Verizon always does extra things to their phones to be a pain in the ass so its not impossible.

european open has this, too, no org htc or logitech or samsung cable is willing to give its juice through, or better, lg ignores it

Actually, I have the Verizon G2 and can attest that NONE of the gazillion USB cables I've had for various purposes over the years (including my Galaxy S3 and S4) will allow for the Fast Charge feature to work with this phone. They only support the slow charge, which pulls only about .5A of current, even if using a 2A charger... Further, I have several cables that dont allow ANY charge whatsoever. They charge my S3 fine (also Verizon), but when looking at battery monitoring apps, they only show as USB connected, but still are discharging..
I'm actually trying to find where I can buy a USB cable that will support Fast charge as I lost my original one... Any one know?

The BlackBerry q10 charger and the nexus 4 usb cable combo is what I use. They charge the phone just as fast, if not faster,than the stock g2 ones.
The only time I get the slow charge notification is when I use my pc to charge the phone.
LG G2

Who is your carrier?

The Verizon model detects anything other then a USB 3.0 charger and forces a slow charge (500mah).
Only the Verizon does this. Only the included cable works. Its not the bricks but the CABLE. We are discussing this in detail in another thread.

Have Fast Charge Working
I have the Verizon version of the LG G2. I have found a couple of ways that it will fast charge. I have been able to use a Nexus 7 charger and USB cable. Also found a car charger that will fast charge: GT Max USB car charger that has both a 2A and 1A USB ports. But it will only fast charge with the heavier USB cables. With the lighter cables (USB sync cables) it will slow charge.
Also found an app called CurrentWidget that will show the battery charge rate. This has been very helpful in determining the right combination.

My N7 charger works but only when using the stock cable. In fact, fast charge (ie normal charge) only works with the stock cable. I have not found another cable that fast charges.
My car has the data pins shorted and will fast charge, but actually doesn't charge at all. A 2 hour drive and my battery was actually lower while on the charger. Goofy.

What charger amperage does the LG G2 Support?

I know the stock one that comes with it is a 1.8A charger but what is its maximum?
(The iPhone 6 supports 2.1A for example)

Hello,
I recently bought a car charger giving 2.1 A and it works perfectly.

Ill pick up a 2.1A, from what I can tell most flagships support up to 2.1A so its probably no exception here

Never got higher than 1.6A even with different 2.4A chargers. G2 full charge always took around 110 minutes.

How are you measuring your charge rate (power/current)? Just because the adapter is capable of sourcing that much current doesn't mean the phone is capable of sinking it or putting it to good use. USB 3.0 charging ports can source upwards of 2-3 amps

[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

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."
Also from http://www.samsung.com/sa_en/support/skp/faq/1063730?CID=AFL-hq-mul-0813-11000170
[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.

General Nothing phone not working with samsung charger

Have a Samsung fast charger, as soon as I connect the nothing phone to the fast charger, it says rapidly charging then instantly says that it's not charging, works with Google's stadia charger but not samsungs.
I'm also going to try my other samsung charger to see if it's just an issue with that specific charger

I don't know anything about Samsung chargers,but are they PD- chargers?

It says on the output it's 9.0V = 15.0W or 5.0V = 10.0W, but even after the update it still charges normally

The Samsung 45W Super Fast Charger 2.0 (EP-T4510XBEGGB) UK plug works fine with Nothing Phone 1.
But if you go and have a look on Amazon there some decent 45W and above PD3.0 QI4 chargers cheap enough, if that helps you.
