Hi all,
Can I please get some advice from someone who might know better than me. I have been using the following charger on my travels to charge an iPad and Samsung galaxy nexus at the same time:
http://www.amazon.co.uk/Skross-Char...?s=electronics&ie=UTF8&qid=1342643375&sr=1-23
I've just plugged my nexus 7 in on its own and I get nothing.
I didn't think the nexus would need a higher amp than the iPad? The Asus plug that's charging the nexus says its 2amp and the travel charger says its 6.5amp. Am I being amazingly blind or stupid here?
And if I need a new travel charger for my trips into Europe can I have some advice on what to buy before I buy something else useless.
Thanks all!

Nexus 7 trouble with other chargers
I see the same issue.
The Nexus 7 charger lists: Output 5.0V===2.0A, Nexus 7 will charge.
iPad 2's charger shows: Output 5.1V===2.1A;Max 10Watt, Nexus 7 will not charge,
Philips universal charger: Output 5V===2A; Max 10Watt, Nexus 7 will not charge.
Blackberry phone charger Output 5V===500mA, Nexus 7 will not charge.
Blackberry phone charger Output 5V===700mA, Nexus 7 will charge.
To answer the OP: The Amazon product page clearly states Output 5.0 VDC / 1000 mA max. N7 needs 2000 mA (2A). Derping in public again. Don't mind me. :silly:
To add to the list:
Samsung Galaxy Tab 2 7.0 Charger: Output 5V ⎓ 2A; Max 10Watt, Nexus 7 will charge.
XtremeMac IPU-IH2-11: Output 5V ⎓ 4.2A (2.1A per port); Max 20Watt, Nexus 7 will not charge. (Galaxy Tab 2 7.0 charges though.)
The N7 seems very picky about chargers, unfortunately. My XtremeMac is now powering my charge cables for my wireless mouse and keyboard, freeing up 2 USB ports, so not all is lost I guess.
I have a 2.1a car charger, but it doesn't charge it.

EDIT: Interesting. It will not work on the car charger wiht my "charging only cable" which has shorted out datapins to register as an AC source. But, it does charge on a normal USB cable.
I have a tf201 charger (here i refer to the usb block, not the cable) that seems to super charge the nexus 7, that is to say, very fast. The tf201 charger is 18 watts. Also, I have noticed my usb 2.0 ports on my desktop will not charge the n7, but my usb 3.0 ports will.

I started a related thread asking if anyone has examined the proprietary aspects of the charger here:
http://forum.xda-developers.com/showthread.php?t=1780211
Basically, we should be able to build (or eventually buy) some type of adapter to enable proper charging with any 2A charger after we figure out exactly what the charger is doing. I wouldn't be surprised if all Asus tablet chargers already worked properly without an adapter.

This answer is clouding up a lot of legitimate discussions. The current rating doesn't matter to this conversation at all. If the current is above 0 the device should show the charging icon. If not, there is some other problem.

You are correct that my remark about the OP's charger's current was not a valid point. I have stricken it from the record.
That said, some serious weirdness is going on with the N7 regardless. On the XtremeMac charger the N7 will charge. But incredibly slowly, and the battery status reads as discharging, even though the line on the battery graph is rising. I don't even know where to begin in trying to explain that.

Agreed. I bought a pair of dual 2A chargers and neither of them will charge it at all (no charging icon). I tried shorting the data lines and still nothing. The dual charger that came with my Razr will charge it slowly (about 16 hours from 0 to 100%). My old 700ma Blackberry charger works just better than anything other than the OEM charger. Frustrating and I don't want to keep ordering different chargers with my fingers crossed.

I don't know what a XtremeMac charger is, but I'm assuming it's for charging an iphone or ipad or something? the Nexus 7 and the apple products don't share the same charger design, so the Nexus is probably only drawing 500mA while charging from it.
You can also add the MonoPrice 8856 charger to the list that do not work with Nexus 7
Mine is charging with Galaxy Nexus 5.0v 1.0A charger.

I have two chargers that work.
1: Nokia 1.2a fast charger
2: Blackberry 1.8a charger
both have integrated charging cables, which are 6ft in length.
The Asus transformer prime which is a USB charger with proprietary cord also has something weird. Other USB chargers with the same power specs connected with the Asus USB cable won't charge the prime. Or they charge where it literally takes like 24 hours to reach 100 percent.
There's something different in that Asus power plug on both devices it seems.

I'm not sure what It's output is but the standard Verizon branded micro usb charger does a great job charging my N7. I think they for sell around $30 in the VZW stores tho.
The 1.0a charger that came with my LG Revo works great, almost as fast stock. I bought 2 extra of that charger on amazon about 9months ago for under 10 for the pair.
Also the charger for my old Droid (.7a iirc) works as well, but it's slow as hell with the screen off, and barely keeps up with just web surfing.
The Charger with the HTC Desire seems to be charging - though slowly as its a 1A charger.
Does anyone know whether the International Samsung Galaxy S II charger works?
The TF101 charger works great, and fast too - about 1% a minute.
My Samsung SG2 (i777) charger seems to work with the N7
I have read countless threads and looked at many chargers and I just can't seem to find a 2a car and a 2a home charger. I just ordered this charger and this cable and it just doesn't work above 700ma. When I use the stock cable I get to 1300mah for a sec and then about 900 steady. This is on both ports. Someone please help me before I lose it! The only one that works at 1500mah is the cable and charger that came with my phone.

Thanks in advance.
Well, I can say from repeated certainty that this 6' cable charges at the same rate as the stock cable but is actually nice.

Also, my Qmadix car charger with dual 2.1A ports does very near stock AC levels when charging 1 device. My results are in the mega 2A car charger thread, but that's a spendy charger.

I saw a cable at Best Buy which is pretty nice, it has El Wire that flashes quickly(battery at 0-65%), slow (battery at 66-99%) and turns off when the battery is full. Would that cable be okay to use to charge my phone?

I have a cheap gas station 2 port usb car charger rated at 2amp for one port and 1amp for the other. Works great and I think it cost maybe 10 bucks. My phone charges at well over 1300mah in the car using a cheap usb cable I got at walgreens or some ****

I'm also looking for 2A replacement... How's the charging time compare to the stock Note 2 charger?
how do you measure the output while the device is charging? Is there an app to test how much juice is coming in real time?
I use a 2A HP Touchpad charger in my living room and a T-Mobile branded 3A dual USB charger in my bedroom (see links below). The T-Mobile charger charges my Note2 from 9% to 100% in less than 2 hours when I only use 1 of the USB ports. I'm not sure what the rate is when both ports are used. I've had this for a couple years and use it to charge (individually and simultaneously) my phones and tablets without any problem.

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)

Dies anyone use the Anker 5-Port USB C as a charger for their phone? Is it capable of charging rapidly? As fast as the original LG charger?
Sent from my Nexus 5x
I actually have one of these and the PowerCore+ 20100 USB-C, which I highly recommend. I feel like the 5-port charger charges the phone a few minutes slower than the LG, but the rapid charge still works. If you need a battery pack the PowerCore+ can charge my phone at least 5 times on one charge. I charged my Nexus and 2 iPhones the other day and it only used 30% of the battery.
I use the 5 port charger to charge my phone, my Nook HD+, my 3DS, Microsoft Band, and my battery pack, and it still does rapid charge.
I finally bought the Anker 5 Port USB C charger and I can definitely recommend this one as it charges my 5X at almost the same speed as the LG charger. Plus,I can charge my other usb devices simultaneosly
Sent from my Nexus 5x
I don't have the version with the C port, but I do have a couple of the Anker 5-port chargers. Using a in-spec USB C to A cable, I get 2.35 amps out of the 5-port charger hooked to my 5X. The OEM charger is rated 3.0 amps, but I don't have a tester for USB C. I would assume it is close to that 3.0 rating. Either way the Anker is pretty close so charge time will only be slightly longer.
I have some more test results in my Slow charger thread.
Overall I'd say you can't go wrong with Anker products. I've now used their chargers, hubs, and card reader. All their products have been quality pieces.
Anker is great.However I do not need a charger like that as all my devices will be scattered on the desktop.I bought a great 4-port USB Charging Station from "ipely" on Amazon. .My honey 6P,iPad3,Kindle,bluetooth headphone could be charged at the same time and everything organized.That is great I think.
