What charger amperage does the LG G2 Support? - G2 Q&A, Help & Troubleshooting

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

Galaxy Note without original charger

Hello to everyone!
I have one simple question: do I risk something if I charge the Note with another charger than the original one?
I don-t know, but I think no.
I charged many time my note with htc charger and gs2 charger.

I almosr never use the original charger. I use the charger that came with the bluetooth headset and everything is fine
It doesn't matter what kind of charger you have. The only thing you must look at is the voltage of the source (5V DC) and it must be a micro usb plug

im using my old htc hd2 charger as the samsung one seems to have packed up and isnt charging properly
The easiest way to charge your Note is of course via a USB>Micro USB cord plugged into a laptop or PC (where you are guaranteed the voltage is correct), however if you are using a generic or knock off wall wart charger than provides a micro USB connector there is some small chance that it will not charge your Note.. look for the charging icon and if its not charging, toss the charger and get another.
There is no specific risk to the device, provided that it (the charger) has a micro-usb intended for charging generic devices..its just that some modern portable devices have a stricter requirement (tighter tolerance) for charging voltage and simply will not charge outside that voltage range.. my BB9930 does exactly this..

Since all micro/mini usb chargers have the same voltage, and vary only in the power output - the only problem you could face is slow charging, or no charging at all if the charger doesn't have enough juice. But it certainly won't harm the phone.
I'm using my old Nokia N900 charger without problems
I'm using an old HTC mains-to-USB and a Nokia microUSB cable...
My stock charger has a slight squeal, so I usually use the charger for my BB Curve 9300. Does totally fine.
My Note was purchased from expansys UK but shipped in from mainland Europe. As it was to be sold in the UK, expansys had to supply a UK adapter rather than an EU one ...I received an HTC adapter with my phone. At first, I was worried, but discovered that it works beautifully with my Note. Charges faster than generic Samsung chargers too! You should be fine using another standard charger

For the first 3 weeks I was using a blackberry (original) Bold II charger.
I noticed charge time was too long. And maybe even battery life was shorter.
Im not 100% sure about the second statement but the first is confirmed.
When I started using the Note charger it was faster. Not super fast compared to iPhone or iPad but faster than using the Bold charger.
I never use my samy charger..Im using my DHD charger..no problem at all..

Most modern USB chargers should be fine (I use my old iPhone charger for the Note, for example.) Watch the power output though - some tablet chargers are rated at 2A+ and that could overdrive your charging circuit and cause damage. If you make sure your charger is about 1A (and 5V, obviously) then you should be fine.

Well emuX said it all!
1A of output and 5V and you are fine!
Actually the charging current is limited by internal resistance of the battery, so the battery effectively "accepts" charge. Charging current is not "pushed" in by the charger...
obviously a charger from say a BB is likely to be current limited and so longer charging times would be expected, but an iPad charger will work fine.

I wouldnt worry too much, I charge my note with my iPhone charger purely because the USB port faces a different way so I can actually fit it on my plug extensions without loseing 2 sockets.
Pretty much anything with an output of 5Vdc and a minimum of 1A will do just fine.

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.

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.

Third party chargers for the N4

Ive noticed the stock wall charger delivered with the Nexus 4 is rated at 1.2A, 5.0V. My old phone had a micro usb charger at 0.8A, 5.0V. I imagine the N4 will charge on the lower rated charger, but would take longer. Isnt the standard usb rated at 0.5A? My desktop PC has a new Asus board that has the Charge+ 3X Faster Charging, which I would guess means the usb can pump out power at 1.5A. Looking around for a car charger and additional wall charger, I imagine the N4 would be fine with a higher and lower rated charger? Or should I stick with 1.2A or less? Ive seen car chargers at 1.0A, 2.1A, and 3.0A.
the n4 will only take the current that it needs. a higher Amps- rated charger won't hurt it.
i use a 2.5A portapow quad output charger, the extra power of which enables the charging of multiple devices simultaneously.
I bought this charger for s2 when I had it.. and sold the phone immediately. However I still have this charger. Now what I want to do is, keep one charger (stock) at home and the other (Nokia one...which is also Original) at my workplace. I want to know, is it compatible? As the manual say, u shouldn't use 3rd party chargers. So I want to know your expert opinions "before" start using it on N4.
Thank you
I use my old blackberry + LG car charger
^ You think this would go fine with my N4?
The Output/Input is all same.. only 160 mA is diffrent from the Stock charger. So I don't really know.

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.

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.

Well, I don't think Motorola really advertised "Turbo" charging for G4 Play.
They advertised something else. Here's what it says on their site:
Moto G Play works with the 10W rapid charger (charger in-box), which gives you 5 hours of battery life in just 15 minutes of charging.

The fact they package with a low spec charger in a $150 box is not a concern. I own dual and quad chargers I carry for phone tablet BT etc.
The question is a specific charger able to charge faster? I looked at the one supplied and it seemed to imply a 5V input then as much Amp as phone can take, which is usually about 1-1.5A til 85%.
Turbo, is I think like QC, it increases the voltage at low battery charge, such a charger would show say 12V or 9V output.
Is there any good charging app to watch what the phone is doing? I have iSmart, QC 2.0 and QC 3.0 devices I can test on.

The way I find best is to not use the phone and use a stopwatch and measure at 15m intervals.
It does take days to be ready with a low charge condition.
App I have used is Ampere but I find it unreliable as the act of using the phone means heat throttling down the charging speed, if you don't use the phone then Ampere sleeps and doesn't monitor.
From what I understand, it does support it but you have to buy an additional charger.
It definitely does some kind of fast charging because my Anker Powercore+ 10,050mAh power block charges it incredibly fast. I don't know what other charging methods the Anker does beyond qc2.0 since I have had the Anker less than 12 hours.

If this behaves like osprey (which I expect - I haven't yet examined the kernel), the hardware doesn't support the Qualcomm high voltage quick charging, but it does support regular charging up to 800 mA. The weak 550 mA charger bundled with the North American variants will not make the most of it, but a 1A charger or better should get full charging performance.

So does this mean the 2.0 A bundled chargers are bottlenecked, like they support 2.0 A and the phone supports only till 800 mA...am I thinking correct?
My XT1607 US unlocked retail version came with a 5V 550mA labeled charge plug. I used a cable and power plug from another device that rated at 5.2V and 1.35A and it drew about 1.4A from it. Then I dug out another USB adapter rated 5.3V, 2A . It consumed 1.78A and it was 80% charged at the time. That would make for some much faster charging than the original plug. Wouldn't matter much if you just plug it in overnight to charge.
Anyone confirm if the it supports QC 2.0? Only thing wrong e phone is slow charge from supplied.

Logic fail. The supplied charge is feeble like 0.5A so anything like 1A or 2A is better.
That does NOT mean turbo is supported.
When I plug my G4 Play into my Anker 4 port power supply and then into a kilowatt meter, it draws 10 watts. If we work it backwards, that's 5v and 2 amps (however, need to account for line loss, transformer loss and other losses). A watt is a watt, doesn't matter what the voltage or amperage is, as W = V x A.
This phone charges much quicker than my old Moto G second gen, which would take close to 2 hours to fully recharge. I have had this phone recharge in as little as an hour from around 30%. It's a shame that the SD 410 chip supports QC 2.0 but Motorola didn't enable it. It seems to have QC 1.0 (which is the 10 watt, 5v @ 2amp rating).

Regular USB is 2A 5V 10W.
https://en.m.wikipedia.org/wiki/USB
Standard USB 2.0 is 500mA
USB 3.0 is 900mA
There is a new subset standard called USB power delivery, it's used for newer devices.
Quick charge 1.0 was 2 amp at 5v.
There's a little more info here. https://www.easyacc.com/media-center/quick-charge-3-0-vs-2-0-vs-1-0/
These phones charging at 2 amps is technically quick charge, whether it's the 1.0 revision or not is really down to licensing and stuff. They don't charge at 2.0 speeds unfortunately. Even though the chipset supports it.
