[Q] 2A charger under $20?

I recently bought the official s4 qi charger using the 50% off code. I forgot to purchase the required 2 AMP charger to power it (I didn't notice that wasn't included in the package). Since I don't have an S4 (I'm going to use the charger for my Nexus 7 FHD and my S3) I'm trying to find a 2AMP charging block/cord that I can trust.
I hate to start a new thread about this, but I searched all over Amazon and XDA and the best solution I could come up with is this:
http://www.amazon.com/gp/product/B0...PWYPY7NWWHH&coliid=I321ZTUWIDWWO3&me=&seller=
I'm confident this one would work, but it's cord is connected to the brick and it's black and not white. I would prefer to have a separate brick so I could use a white cord to match the white s4 qi charger on my desk.
There are MANY solutions out there but each one I've found has mixed reviews when it comes to Android products and some even mention catching on fire! I hate to go the non-OEM route... but signing up for another account on Samsung's site and paying shipping and tax again will bring my total close to $28 dollars. At that point I might as well return the charger and just eat the shipping cost to return it.
TL;DR: Does anyone use a non-OEM charger that was under $25 with their S4 qi charger and can verify it doesn't catch on fire???
Thanks!

Currently using Monoprice 4 port wall charger ($7.80) to handle the charging of several peripherals at once. Note that only one port is rated at 2.1A/iPad compatible, whereas the other three are regular 1A USB ports.
Same deal but with two 2.1A ports and two 1A ports: $15.25.
Just one 2A port: $5.56.
Monoprice FTW

Some are on backorder.

A review from that listing "

Hmm then i suggest get the original charger with cable, coz i have seen if i use any other cable s4 charges pretty low around 900ma if original cable then 2A definitely because its takes lot of time otherwise.

If you order from amazon make sure to change the seller to a reputable dealer. I got one from seller1on1. The cable was shorter but the current was the same as the oem one

I've had great results with the rocketfish charger. under $5 at amazon.

Don't forget that our S4's have the 11 pin micro usb connector. I used an older 5 pin one and wondered why my 2amp charger took forever to charge my phone, rather than the 1.5 hours it normally takes to fully charge.

The extra pins are only for MHL.
The stock charger has 4 visible pins.

Wireless charging.. Good or bad?

So I figured a wireless charger will prevent my otterbox from stretching out and all. What ive found to be a pain in the ass compared to all videos ive seen. Every one people just throw the phone on top. Comes on charging. My phone complains for me to center the circle on the screen with the dot in the center of my QI charger.
Anybody else notice this? Or is the droid maxx just a pain in the ass to wireless charge?

I think it's a good idea. This is the reason I bought the Palm Pre

I dont like wireless charging too much. Jt wasts energy and isn't much "stylier" than charging it in a dock.

Its nice but I prefer to charge via wire my s4 stock charger charges at 2 amps a second where as the wireless charger only charges at around .5 amps so instead of taking around 2 hours to charge it would take around 5 hours .

Hi, I think there are a couple of technical specs being quoted.
. . . my s4 stock charger charges at 2 amps a second . . .
Click to expand...
Click to collapse
I think you meant the charger rating is 2 amps. Battery has a rating of amp/hr, but not chargers. They are only rated at amps. E.g., if a battery is rated at 60 amp/hr, and it is flat, to fully-charge using a 2 amp charger it will take about 30 hrs (30 * 2 = 60). That's only theoretical because other factors take into play: the condition of the electrolyte, the physical condition of the battery, the performance of the charger, ambient temperature and humidity, etc.
. . . the wireless charger only charges at around .5 amps so instead of taking around 2 hours to charge it would take around 5 hours. . .
Click to expand...
Click to collapse
If charging at 2 amps take 2 hours, then charging at 0.5 amps will take 8 hrs (2.0 / 0.5 * 2 = 8)
In the above examples, I am assuming that the battery and charger Voltage rating is the same.
Just clarifying.

I want a spot in my car where you set your phone and it wirelessly charges while playing your music via bluetooth and doing calls/texts via bluetooth and voice. Set your phone there when you get in the car and it is fully powered, charging, and ties into everything. It needs some mechanism to keep the phone there (some sort of clamp?) and be positioned well for GPS usage.
Wireless charging will be awesome once there is a standard and it starts getting built into things like that.

seems to be a good idea so far i like it

bad idea

That's the one thing I wish my phone had. Want this feature very bad.
Not to even mention for the no wear and tear on the Charging Port which can be a weakness.

which devices supports wireless charging

It charges my phone slowly.
Stock charger takes 2.5 hours and wireless chargers takes 3-4 hrs to charge full.

Think of it as a transformer with the primary and secondary coils not firmly attached to each other. It's no more dangerous than any AC adapter. Of course, if they decided to make these chargers to work at a distance, there might be some risk. (shades of Tesla!)

I totally agree, there should be thorough study on the electromagnetic waves not affecting the memory cards and the volatile storage inside the phone... might result in data loss?

charging galaxy s4 i9500 with 2.1A and not 2(stock)

http://www.ebay.com/itm/3-1A-Dual-U...S_Cell_Phone_PDA_Chargers&hash=item565a917530
hello
My stock charger is us for galaxy s4 (samsung regular charger)
and then I found this (link above) with 2.1A
is it matter charging via 2.1A and not 2A? what is the different? it will charge faster/slower?
thanks

In Stock kernel there is current limit 1.9A. So everything above it, will be the same as 1.9A.
In reality, you will find that even 2.1A charger doesn't supply even 1.9A. Chinese charges definitely don't supply current thay claim. And beware of them - you may fry your device by such cheap charger.
Also, it heavily depends on USB cable as well. It has to be very short and very thick.

I have a Mediabridge car adapter that has a 2.1 amp charger on it. When I charge my S4 with it it barely charges faster than the 1 amp charger does. I think it charges at either 1.3 or 1.7 amps, sorry can't remember exactly.

I don't have the equipment to measure it exactly. So what I did was charge my phone from 50% for 40 minutes on my stock Samsung wall charger and then recorder the percentage it increased. I then took that number and assumed it was charging at 2 amps and used it as a baseline. Then I did the same test with my car adapter and recorded the results. The I figured out the percentage difference and came up with me estimates. I just don't have the data in front of me anymore but I remembered it being somewhere between 1.3 or 1.7.

Chargers, power supplies, etc, don't "decide" the amps that go to a device - the device "draws" a certain amount. Just because a lamp is plugged into a 20amp circuit in your home doesn't mean 20 amps are going to be shoved through the bulb.
So if, as sorg says, the phone is only going to "ask" for 1.9a, you could plug it into a 5 amp charger and it would make no difference.

You already got your answer above.
No, your phone will NEVER charge faster than 1900 until a developer comes along and figures out how to hack the system to allow this. And it would be a potentiallly STUPID idea to charge faster than Samsung has deemed safe.

powerbank 2A output bad for phone ?

What's the side effect of using 2A output powerbank on the cellphone ?
From my experience, the output of cellphone adaptor usually between 500mAh-1Ah. Well, except phone with bigger screen (which i don't have).
What i notice is, the back of the phone are usually hotter compare if i charge my phone using phone adaptor or via usb.
I am kinda worry with this excess heat. Heat is not good for electric components.

It will shorten the lifetime of the battery

What about a phone that's designed for 750mAh and it's being charge with 1.2A powerbank ? Since the common minimum powerbank output are 1.2A.

Even that would be harmful there are 500mA powerbanks available which would be ok

What about the opposite. 1.5A capable cellphone that's being charge with 750mAh charger ?
I think it would be fine. Just the time it needs to charge the phone is longer. What do you think ?

That would be perfectly ok, you're right it just takes longer to charhe

it does not work with my touchpad (HP). If i not charge with 2A output is no charge

Charging cord?

Is this thing a joke? It's barely 3 ft long. How the hell are we supposed to use this effectively and safely without it falling on the floor plugged in and crack the screen? It barely reaches my bedside table.

Buy another charger? I use the blackberry playback charger personally long cable fast charging and pretty cheap to buy.

Adjust accordingly. Just know that if u do replace the cable or use another charger, the charging rate won't be as fast. See https://forums.oneplus.net/threads/oneplus-one-charging-cable-alternative.68517/
But I completely agree, it should have been longer. I just adjusted accordingly and all is good now, the cable should have been at least 6 ft.

I have no idea about that, maybe someone else can provide input on that. I do love the fast charging rate on the phone though, I'll even pay OnePlus $5-10 to have a larger usb cable with their special battery juice.

Yup I know how you felt.. I used the blackberry folding charging for my N5 and it charged super quick and the cable is super long.
The blackberry folding charger was 1.8A.

I thoroughly recommend the blackberry charger. It has to be this one:

Should be able to grab it from your location too. A lot of sellers sell this particular charger. It's got a 6ft cable and charges quickly. I've replaced all my chargers with this one and it works a treat.

http://www.amazon.com/s/ref=nb_sb_n...ng charger&sprefix=blackberry+folding+cha,aps looks like they became more expensive, I paid $5 for 2 back when I bought them.

I got some off monoprice for $7.

Glad I found this thread. I never even took the stock charger and able out of the box yet. I have a generic usb cable plugged into my iPad charger. It took almost 8 hours to go from 3% to around 80%. I think I am gonna start using the included charger now.

If you're looking for a longer alternative, this one will charge at the same rate as the original cable.
