Hi all.
What is the recommended voltage and amperage output for a car charger for my NS?
I got an aftermarket one here that is 5vdc/500mA, but my NS gets really hot while charging with this one.
Thanks

The NS will get hot while charging, especially if it's being used at the same time. It's normal.
You definitely want more than 500 mA though. The NS can easily draw more than 500 mA while in use. 1A car chargers are easy to find and will work much better.
5V is a requirement though. That's standard USB voltage. The voltage doesn't change from charger to charger.
1A. Great, thanks for the response.

Was wondering whether there are things to watch out for when considering wireless charging. The charger supplied with the phone is a normal one as far as i know. Are there any drawbacks when using any wireless charger? Is the hp touchpad touchstone compatible? Any info will be much appreciated

they generally charge slower. maybe twice as long(or a little less than twice as long)
The touchstone probably won't work - it's not Qi compatible.
If you're using the Nexus 4 wireless charger, the good news is that the 5 doesn't generally slide off.
Hey guys!
I've got a Samsung S Charger Pad (Model: EP-P1001EWE) and i am not sure if i should use it to charge my Nexus 5.
It's an inductive charging Pad.
Will it ruin my battery or isn't there any danger?
Facts:
- It does charge
- There didn't come an actual charger with the Qi Pad, so i am running it with my Nexus 5 Charger (which can be plugged into the pad by micro USB)
- My Nexus 5 Charger has an Output of: 5V/1,2A
- The Qi Charger says: Input: 5V/2.0A
Thanks for your help!
The Samsung charger pad uses the Qi standard so you should be fine. The output and input voltage of the charger match so that's okay, but since your charger supplies a lower current than the Qi charger takes, it might charge your phone slower than it should.

The original Google Qi Charger has an input of 9V and 1.8A.
Does that change anything?

The Qi output should be the same regardless so you should be fine.

So i can buy a charger with the right output (matching the Pads input) and can use it as normal?
Sent from my Nexus 5 using xda app-developers app
Yep, although unless the pad is currently charging your phone noticeably slower than it takes to charge it by cable, it might not be worth bothering.

It does charge pretty slow... So i ordered one! Thanks for the help! I'll be telling you guys if it was worth it

I bought a dual usb car charger from eBay that is supposed to output 5v 2A on one socket and 5v 1a on the other, but while leaving it like that in my car it still drains the nexus 5. Tried to only have the nexus 5 connected to the 2A socket aswell but still discharges over time.
What can be the issue here?

Probably either a bad USB cable(s) or chargers that are not putting out the amperage as advertised. There are a couple posts you can find in the accessories forum that show the effect of low vs high quality USB cables. Summary: there is a big difference.
I've personally been on the hunt for good cables and charges for a while and recently bought a car charger that charges while I listen to music and use Waze while driving. Very happy now, we'll I am, my wallet isn't.
Try current widget while hooked up to the charger. You can test how many amps you are drawing.

It may be like the post above, drawing USB charge. I think I read somewhere there is a mod to enable fast charge.

Tried some different cables in the truck now at lunch, the ones I used before got minus even while charging, these were cheap flat cables from China, tested with an Asus one i had laying around and that gave me ~700+ mah. So from -70mah to +700mah is quite the difference just by switching cables.

Samsung offers two wireless charging pads. One is mini and the other is standard size. Is it just the size that is the difference? Does one charge faster than the other?

It looks like the mini only does 1amp charging while the standard does 2amp charging. In short, the standard will charge your phone faster.

That's totally lame. I was going to get the mini just because it looks better and more professionally styled. But I guess not anymore.

Where did you get that info from? In the description of the mini one it clearly states is comes with a 2A charger!
My understanding is that the mini is a new model released with the S5 whereas the other has been around for at least a year now.
Even if it comes with a 2A charger it only charges at 1amp. It's a limitation of wireless charging

He said one charges 2A and one charges 1A. Is that even possible?

Even if the charger is 2amps, it will only charge at 1amp wirelessly

Well that kinda blows. And makes wireless charging a whole lot less attractive.

I guess that sorta makes sense. I figured I'd use it more like drop my phone down to charge up a bit real quick before heading back out the door. Kind of a busy life style type thing.

Ya, it's not good for that. It won't charge it as fast then

The S5 has more than 2 points of contact for the wireless charging back. Not sure if it is for nfc, but maybe the doubled the charging capabilities by having two separate charging coils?
Edit: This is my first post is 5 years, I feel like a lurker.
The power of pad doesn't matter, the coil from the back of the case is the charging source. So for s4 note 3 it's 650 mamps and the new one for s5 is 700 mamps( if i spoted right in the pictures). The difference is in aspect and size only.

Are they up to 1A now? Last I checked, there wasn't a wireless charger anywhere that charged faster than 850mAh. Which is only 30% as fast as the USB 3.0 charging of 2500mAh.

If you look at pictures the S5 official wireless cover charges at 760ma.

1amp is theoretical charging speed.
Just like how the phone stock charger is 2amps, it will max out at around 1.8 amps

crazy deal alert!!!!

$5 each and if you buy 3 or more, you get 25% off, so I got 3 for $11.25
Here is a review of it
http://unleashthephones.com/2013/01/26/nokia-fatboy-wireless-charging-pillow-review/
Get them while they last!!
I have three wireless chargers. The small original Samsung, one Nillkin and a noname. I am using the original charging back from Samsung. I am very happy with the small original Samsung charger. The S5 gets much less warm than with the both others and it stops charging at 100%.
I had it on the Nillkin over night and the next day when it has been at nearly 100% already in the evening it was extrem hot at the morning and still charging but it showed 100% but not the full message at all. Very suspicious. With the noname I very often have the wireless charging detected message when it comes over 9x% so it looks as if the charger often "looses the connection" to the wireless charging back cover.
The original small Samsung charger says 5,3V and 2A on the back and it loads at maximum wireless power with the original back cover and the original power supply. For me this is the best combination. The only thing is, that you cannot use the S5 very well while charging because of the small charging pad. I most time take the charging pad with the S5 in one hand so it cannot tilt.

3 coils vs 1 coil.
3 coils is better with cases and easier to place the phone on it.

Both samsung charger are 1 coil.
3 coil offer a wide surface detection, but does not mean it's better that a single coil charger.
