[Q] Charge with 5V/2A..?

Hi guys!
I have recently bought a Nexus7 tablet which has a 5V/2A charger .
Can i charge the i9305 with the Nexus charger (5V/2A) or it will cause problems..?
Thanks in advance!

I'm not sure of the voltage of the I9305 but the more volts = faster charging but hotter and hotter means a shorter life for the battery but it should be fine, I would trade it for faster charging. For amps, I have no clue and please correct me if I'm wrong anybody.

I'm pretty sure that you are saying the opposite way.
You can use more Amp but not more voltage.
More Amp - charges quickly.
More voltage - could blow your device.

AW: [Q] Charge with 5V/2A..?
In principle, the battery would load faster at higher charging current when the battery is capable of fast charging. If not, could reduce the battery life. I believe according to the charging control of Samsung, a current limiter is installed that can always draw only 1 amp. So it brings no benefit to using the charger of the tab. It may also be that the charging control of the current is limited so that is not loaded. The phone should not be harmed.

Should be fine for short term use.I've used half amp one amp and one and half amp car chargers wouldn't go any more than two amps no need to..may degrade battery a little so what there cheap enough to replace lol..easy peasy.. I live in tents an caravans 24/7 use leisure battery's not problem with amps just volts..bless solar panels..

The phone take what Amp it needs.. No more than its made for. 2A is only what the maximum out is for the charger.
You could make a charger with 50A, the phone still dont take more.
The volt is the value that need to be fixed though.
All phones charged via a usb needs 5V, no more, no less.(Usb =5V allways) Most batterys now days is something like 3.7V. Correct me if Im wrong.
Any way, you need a couple more volts in the charger than the battery to charge it.
Answere=Yes.. go ahead and charge.

I have had an HTC HD2 and used it's charger to charge my SGSII and now my SGSIII.
The time taken to charge with that is about the same as the SGSIII charger.
The charging circuits on the phone are smart enough to know that you are charging from a mains' adapter instead of an USB output from a computer and thus adapts the current draw from the system.
I previously did tests on the HD2 regardsing charging times and even with bigger supplies that the 1A one from HTC, it did not charge any quicker.

That charging circuit is made to cooperate with the battery and the rest of the phone.
So only difference you will notice is slower charge time if you are using a to weak charger that cant deliver the right amp.
As mentioned earlier you could use a 50A charger with out any faster charging time. Amps is allmoust of no interest if its not to weak.
Look at electricity as water. Amp is like how many liters of water a sertain pipe could deliver. Volts is more like how strong the flow is. To mouch pressure will destroy the flower. But with Amps you could pretend that the flower demands a certain amount of water and it will not suck more just becaus it could get more.

hilarious jab at samsung

Idk if this is just for the vzw version of the g2 but anytime i plug it in to one of my samsung chargers that came with my galaxy nexus (when on the stock vzw rom), instead of going to slow charge mode it says something along the lines of it being a substandard charger and that i should plug the cord that came with my g2 to charge it safely then cuts the power. Has this happened to anyone else using samsung chargers? Or could it just be that it really did dectect something wrong with the 2 particular samsung chargers i tried?

The actual charger that comes with the G2 has integrated QuickCharge 2.0. Hence why you will notice much, much faster charge times.
Not many other chargers and phones have this capability.

I get that with a BlackBerry charger, too. It has to do with the amperage output.

Yea i get that its faster w the stock charger what i was saying is that normally you get a notification when using a non stock charger that its in slow charge mode but with all my samsung chargers it wont charge at all, it shuts it off compleatly. I thought it was a Samsung specific thing but apparently it has to do with certain amperage outputs it wont let the phone charge with

You make it sound so special
It's nothing more than a high output charger. Plug it in an Ipad or > 2.0 AMP charger and it will charge just as fast, without the fancy "2.0" technology

Ohhh so thats why it charges so fast! Mine gets 15% up in literally 15 minutes lol. I go bed 21:45, at 22:00 its already beeping that its full back from 85% xD Great stuff really:good:

Yeah idk it seems like it does charge a lot faster, definitely a lot faster than my S III

This phone is stupid with chargers.
I have a dual charger, 2.3 amps and 1 amp. It fast charges on the 1 but complains about the other.
It complains about an HTC cable and cuts charging, but will charge normally when simply unplugged and plugged in again.

any benefit using 2amp charger ?

Hi, im just wondering is there any benefit using a 2amp charger on the htc m8 , faster charging ? i know HTC are gonna release a faster charger which is 1.67amp , is it just the amp or it has some feature Quick Charge 2.0 built in you cant get with other chargers ?
the HTC One is rated to support Quick Charge 2.0 capable of accepting up to 60 watts of power – an increase of almost 100% compared to phones with Quick Charge 1.0. The 1.5amp charger bundled with the HTC One (M8), however, does not support Quick Charge 2.0. HTC is planning on releasing an optional 1.67amp charger accessory that will come with the technology later this year
Thanks

Yeah, it will charge a bit faster.

I've used the 2.0A charger that came with my Galaxy S4 and didn't really notice the phone heating up to unusual temps.

You can use a 10A charger if you have one (and it works with your power outlet), the phone should never draw more than the maximum it draws.

I originally used the charger I got with my M8, but then switched to a 2.5amp charger. According to GSam, my time to charge from around 80% to full is around 15 mins, but with the original charger, it was around 30 mins.
So from my experience, it does charge faster. From what I have read about QC2, the technology is in the processor in the phone. The charger can be any type, as long as it is able to deliver up to 60 watts.
See here - http://www.zdnet.com/qualcomms-quick-charge-2-0-offers-75-percent-faster-charging-7000026519/

The tech is actually in both the phone AND the wall charger:
From http://www.qualcomm.com/chipsets/quick-charge
"While Quick Charge 1.0 rests in the devices only, Quick Charge 2.0 resides in both the device, offered as a standalone IC solution or as part of the PMIC (power management integrated circuit) of Snapdragon™ 800 processors, and in the AC/DC wall charger."
The one you link is worded a little ambiguously:
"Qualcomm hopes to take things further by integrating Quick Charge 2.0 technology into standard micro-USB AC/DC wall chargers. These chargers will look and work like standard chargers, but will be able to deliver Quick Charge to compatible devices."
I tripped on it a couple times when reading it too, but it's implying that the tech does not currently reside in standard chargers, since they're still working on integrating it.

guess i will get the HTC fast charger when out and i bet we should get compatible quick charge 2.0 chargers too
Thanks

The amperage of the charger makes no difference, the device will only ever draw the power it requires to charge, no more. so a 5a charger would be no different to a 2a charger if the phone only draws 1.5a for example. find out what the device needs to charge and get as close as you can to that size for protection reasons

Yes, it will charge it faster. I used my 2amp charger and it did charge it faster. The phone may have some protection built in to protect the phones hardware. But the battery can handle much higher charge rates and the battery shouldn't start heating up till 20-30 amps. Yes, that's right.
I use Li-poly to race electric RC's and we charge them up to 50 amps. This charger will --->http://www.hobbyking.com/hobbyking/store/__46368__iCharger_308DUO_1300W_Dual_Channel_8s_Balance_Charger.html
Most people only charge at 5-10 amps, but to get peak performance, you will need to create a bit of heat and that doesn't happen till 20-30 amps.

Since I jumped from my old note 3tothe m8 I was able to keep the charger and it's a 2A one. Will I get the full 2.0 benefits with it or must I wait for the HTC one?

You will get whatever amp the M8 can take. i assume its 2A
I have a 2amp charger and i use it for my M8. i only see about a 30 min different from using a 1amp charger.

Its not just Amps, quickcharge 2.0 Also bumps up voltage. I tested multiple combinations with my htc one M8, here are my findings:
Quickcharge 2.0 18W Aukey (with regular micro usb cable): 9v/1.1A (~10w)
Quickcharge 2.0 18W Aukey (with data cut off cable): 5v/1.52A (~7.5w)
Wall 5v 2.4A charger: 5v/1.52A (~7.5w)
Stock 5v 1A charger: 5v/0.99A (~5w)
Car 5v 2A charger: 5v/1.3A (~6.5w)
some old 5v 700mA charger: 5v/0.7A (~3.5w)
MacBook Air USB port (2013) (with regular micro usb cable): 5v/500mA (~2.5w)
MacBook Air USB port (2013)(with data cut off cable): 5v/1A (~5w)
Ipad charger rated 5.2V/2.3A : 5v/1A (~5w) (no clue why its so sucky)
Also I noticed m8 once connected to charger (non Quickcharge 2.0) slowly increases charge current. if voltage drops below 4.92v it drops it back to these fixed values, whichever is immediate lower: 3oomA, 500mA, 700mA, 1A, 1.3A, 1.42A. 1.52A
these values are as per multimeters.
my car charger is tricky, it sometimes just falls to 1A instead of 1.3 as it border lines V to 4.92 while at 1.3Amps. (it is rated for 2.4A)

HTC Rapid Charger 2.0

Just found out HTC is going to release a charger that will charge any snapdragon 800 and above HTC device; 60% in 30 mins. I may actually get that depending on the price BUT then again I hardly ever need to charge my device more than once a day unless I didn't charge it overnight.
Also Motorola has a quick charger too. Not sure if its faster than the HTC one BUT it is compatible with HTC devices.

I wonder how much faster does it charge than the note 3 charger?
Sent from my HTC One_M8 using XDA Free mobile app

One thing to keep in mind though, charging the battery that fast can actually decrease the battery's life span. a healthy recharge would be a slow one. Yet i can see why some people would need a rapid charger.
This topic should probably go under the accessories.

I agree 100%, its a simple fact in all battery's, faster charging means also less capacity from each charge and faster draining of battery and also shorter battery life in general..

From what I understand, this is not just a case of throwing more voltage and current up it.
The QC2.0 chargers are different. They utilise technology within the charger and the phone, I'm assuming to distribute the voltage and current in a stabilised battery friendly way. You can use a 2a charger on any device and it'll charge a battery quicker but risk reducing battery life. These QC2.0 chargers only charge Qualcomm devices rapidly. So they have to be different to regular chargers.
I'm lead to believe they kick out 9-12v at 2.1a.

I'd assume HTC would work on trying to not weaken battery life span while charging at quick speeds.

It doesn't matter what software/hardware configuration is in it, as long as it's the same lithium polymer being used it will still be susceptible to stresses like deep discharges, charge voltage, temperature and load currents.
Also, the 60% in 30 min refers to Qualcomm's benchmark tests with a 3300 mAh battery. The M8 has a 2600 mAh batt.

100% in 30 minutes.... I'm drooling. For those long double days.

Yea your right. HTC said 40% faster charging.

It's quite a nice idea for people who travel a lot and always be on the way. I feel satisfied with my OEM though, charges a full cycle in 2.5-3 hours and I usually charge it at night so it's not a hassle

Does anyone know if there is any substantive data on whether chargers utilizing quickcharge 2.0 do, in fact, reduce overall battery life? I could see this being useful in some scenarios, but I like the battery life on my M8 and do not want to do anything to jeopardize it.

Not until end users have done extensive testing. Qualcomm and handset manufacturers and accessory manufacturers are hardly going to advertise this information.
I personally do not believe it will affect battery life drastically. As I said before, it's a technology utilising chips and software within the charger and handset. It's not like shoving a 2a or greater bog standard charger up it.

BUT then again phone companies like to make your phone die quicker so you can buy their latest device. I don't HTC would do that so I believe they would try to make the battery stay the same length of time.

It's just been rumored throughout the years. It's like how some companies like Version (rumored again that most people believe) force some manufactures to not have an sd card slot or something like that so people can use cloud storage which means using more data and possibly going over your monthly limit and paying extra per month for overages. Don't know how true it is but all this rumored.

Wife just got a Droid Turbo...I'll try to remember to do a test in the morning and report back...

I use my Samsung 5.3v 2a charger...I go from 0 to 100% in 2 hours that saved me over 30 min charge. Time...

Can you get this Rapid 2.0 charger by HTC is it out yet? HTC site says out of stock but I didn't know if it was even available yet or if anyone else had it. I tried to google it and couldn't find it anywhere. Someone at work stole my original HTC charger that came with my M8. I know HTC does there 50% off deals too alot on Tuesdays.

Any charger that has Qualcomm QuickCharge 2 built in.
They are a little bit more expensive, but are worth it in my eyes.
They charge a lot quicker than normal chargers as the charger monitors battery temp and delivers maximum charge without stressing the battery.
I can charge my phone from under 10% to charged in 2 hours and it's not even warm.
When I plug the phone into my PC at work it gets really hot and I'm sure that's not good for the battery.

It CAN be charged by any QC 2.0 charger but you won't get any out-of-the-box. The standard charger is EP880 paired together with EC803 charging/data cable. My original charger stopped working after just 10 months and now I'm using Blitzwolf BW-S2QC charger.
But it's true - quickcharging a phone does not even make it hot or anything like that. Unless you start using it but it's my case
I recommend buying QC 2.0 charger.

Be sure the cable you are using supports quick charge 2.0 as well
