[Q] why lg charger charge twice faster than tab s charger? - Galaxy Tab S Q&A, Help & Troubleshooting

i have lg pro 2 charger and it charge my tab s faster than the samsung charger
why is that?

check the V. My Note 2 charger charges slower because its 5.0 V, but the tab S is 5.3 V. Lg charger might be more.

yea you are wright so is it bad to use the lg charger?

lg v is 5 only can this damage the battary?

What you really need to compare is the current output (Amperage) output of the two. 5V or 5.3 will surely be OK. I think the Samsung wall wart is 2.1A your LG wall wart is most likely higher than that and this is really why it charges faster. It might not be good for the battery if it's too high. I don't know what the limit would be....

thank you pro

Your samsung charger is broke if the lg is Truely 2 times faster.

no not broke i tried 2 samsung charger and the same
lg charger was charging the lg pro 2 from 5% to 100% in one hour maximum

Please post the model number of LG charger.

lg travel adapter MCS-Q4UR

Bre careful i recomend u dont use another charger for ur device

How long take you charge from 0 to 100%?
Voltage is not responsible for charging time, but current. Samsung genuine charger has 2.1A current, but galaxy tab S gets only about 1770 mA (1,77A) maximum current (I measure this using voltage/current multimeter).
I have many chargers, and any of them (despite some of them have over 2A current) gets maximum current to galaxy tab S about 1.77A.
I also have I9300, and custom kernel (Boeffla, you can select own charging current from 0 to 1600mA), but i9300 takes maximum 920 mA (I don't know why they develop thi function to set current over 0.9A). Setting current over 920mA nothing changes.
I have to add, that very important is USB cable. Device can test the maximum current of charger, and when cable is not ok (for example cable is very thick) device can use a smaller than charger maximum current. You have to notice, that cable can works OK (transfer and/or charging) but can charge smaller than maximum current. Unfortunately on non-rooted devices you cannot see charging current (on device, of course you can use external multimeter)
I have many USB cables, and some of them on original samsung charger uses about 0.5A what is about 3x smaller current.

buying new sgn charger

Recently, my sgn n7000 charger(1yr old) got damaged.
I am looking to buy new charger of same model, but after searching a lot, i coudnt find a new genuine charger online, most of them are boxed and loosely packed.
i got some gud deal for a charger but its 700ma, it will take a lot of time to charge..
While searching, i got at these product
http://www.ebay.in/itm/Buy-Online-S...?pt=IN_Mobile_Accessories&hash=item3384a4ebb8
but on the samsung website, the note n7000 is not in the compatible list.
i wanna know, will it charge my note properly or not. Will i t damage my battery..!
or else pls give some link whr i can get genuine charger.

The charger looks like an indian version of the one my daughter received with her galaxy s4. White is the colour of her phone and the colour of her charger, it also was 5v at 2A. To my knowledge the charging of the battery within the phone is controlled by the phone and as long as it is supplied with its minimum requirement of 5v. it will charge at whatever current it can within the control of the power management in the phone.
Hope this helps ? I did look at the samsung website in india and they had power units for sale. I dont know where you are ?
Samsung India has 700ma chargers listed..
And do u charge ur note with that one..? Us thr any problem.?
charger
No mine is a 5v 1A samsung charger. I also have an incar charger which is a standard usb charger for any make of phone and that supplies 5v at 1A. I also have a Yiboyaun unit from china which charges just the battery, I have 3 additional batteries I use and charge with this unit from china. I have had this setup for more than a year with no problems.
You can charge N700x with the Note 2 charger (which puts out max 2A). It charges slightly faster than the original Sammy 1A charger/cable. It's perfectly safe because the phone will not take in more current than it's configured.

If it charges faster than 1A its not limiting the input. The note 1 battery is made for 1A chargers. Using 2A will limit the life span of the battery.

Can I charge my GN2 with Nexus7's charger?

The problem is that my GN2 is charging very slowly with the original charger (>4-5 hours). I tried to chardge a LG phone with it and it says "Slow charging due to low current over TA/USB connection". I have a nexus 7 tablet and its charger has the same specs: output 2.0mA, 5V. Is it ok to use it for my GN2?
As long as the charger's voltage isn't higher than the stock one's (5V), you can safely use it. In case of higher current, for exp. 2,5A, your GN2's battery probably loads faster, but may also heat up or even break (worst case).
I'm using different chargers with 5V / 2.0A for my GN2 too and it's never been a problem.

[Q] E975 charger limit on amps?

i am thinking about if my E975 is limited when it comes to how many amps it can charge with bcs i recently brought a 2A charger also tried it out on my Google Nexus 7 2013 and i don't feel like it charges that much faster then my original LG charger with a 3meter flat OEM kable.
the charger i brought is said to charge with 2A while the original LG is only 1.2A shouldn't i be feeling a difference?

No, you shouldn't. You can plug it into a 10 Amp charger, but the phone will only draw the amount it needs. Remember, it's not the charger pushing the current to the phone, it's the phone pulling it from the charger. The charging current is determined by the phone - each Li-Ion or Li-Po battery has a controller curcuit. The important thing is for a charger to be able to provide what a device wants to draw - otherwise, it would charge slowly, or not at all. So, a charger should be rated for not less than X Amp. More amp rating won't hurt, but it won't increase the actual current...
oh this is very useful. I also had the same question.
mine came with a 750mA (.75A) charger. As I left my charger at home during the holidays, I had to make due with one that I bought from a nearby tech store. I was very happy with the charger that I bought as it charges my phone really fast. I found out that my new charger was also a 2A model.
so I guess, in my experience, I noticed a big improvement in charging speeds comparing the 750mA with the new 2A charger. But I guess coming from a 1.2A charger, it only makes little difference.

Galaxy Note 3 or iPad Air Charger

hi. the battery charger that i got with my LG optimu G Pro is ****. its just now that i checked that i have been deceived
its chinese copy and its only 0.2A charger...
now i know the reason why my phone charges soooo slow...
anyways. i think Note 3 and iPad air charger are 2A and 2.4A. so can i use iPad or Note 3 charger to charge my phone? will that be ok?
any one here using that?
thanks
Use OEM LG charger with 1.2 output. I am using LG G2 OEM charger and it charges very fast! But not sure it's compatible completely

If youre tech savy you can make your own,you just need a switchmode 5v regulator (they usually put out up to 3 amps) and you put a resistor across the data pins (i think 100 ohm) and itll charge the phone as fast as it can safely charge. I made my own charger for the car and the phone gets fully charged in about an hour and a half. (With screen on and playing Bluetooth music). Other wise if you buy a charger, get as many amps as you can. Atleast 1.5+ . and to make the phone charge in AC mode if it only says USB you need a resistor across the data pins.
Thats funny... my G Pro came with a 1.8a LG charger, my G2 came with a 1.2a.
Yeah you'll be fine. The "extra" amperage in the charger is available capacity that your phone can draw from, it will regulate itself but that can also depend on the charger and how they pin the USB. Its different than if you have extra volts (like a 10vdc charger which would provide too high of a voltage and damage electronics). I usually charge all my phones at when I get home with my wife's iPad charger super fast. Likewise you can use your LG charger to charge the iPad but will be slower since it has less amp capacity to supply. Part of the reason they provide the bigger charger is to sustain battery level while using the device (It should be large enough that the battery doesn't drain while your using the device while plugged into the charger).
Most computer USB ports typically provide .5a of power and will be your slowest charging option, at best you get a newer laptop with "high capacity" ports and it provides only 1.0a.
I've been using an iPad 1st gen charger with GPro since day one, been working flawlessly for 4 months now. Charges fast.

Is it safe to use my original charger to charge a LG G3 or S4?

I got a original charger and was wondering if it's safe to use it on a LG G3 or Galaxy s4 since it's higher voltage?
If it plugs into the device it's probably fine.
The amps are what to look at. Not for the device but for the charger.
One might say output 2a whatever. Amps aren't pushed they're pulled. If the device doesn't need 2a it will draw less. If ya plug something in that draws more than the charger can supply it'll start overheating.
But yeah it's fine to use. Little low on the amps at 1.35 I know my stock samsung chargers are 2+
