Hello all,
I am trying to figure out which is the fastest charger, wired or wireless for the Nexus 5. To do this, I suggest we gather measurements about the charging speed for the phone charging when it has less than 75% charge.
My results are the following so far:
T-Mobile dual usb wall charger 700-800 mA
this ebay Qi charger [1] 200-300 mA
[1] http://www.ebay.com/itm/Wireless-Qi...l_Phone_PDA_Chargers&var=&hash=item51b121c146
Note that the T-mobile dual USB charger was the power source when using the Qi charger and the same microUSB cable was used in both cases.
Does anybody have a wired or wireless charger that can charge faster?
Also, I am using the Elixir 2 app to measure the mA, is there an alternative that does not require the screen on (I feel that it may affect the measurements)?
The one that outputs more mah will charge faster.

They're both awful outputs u need at least 1000 mA / 1A output. You can damage the battery with underpowered charge rates
Also that eBay link states 1A output in the description

Guys, for the wired chargers, we are not talking about the STATED MAXIMUM OUTPUT here, we are talking about the output IN PRACTICE. Most chargers are rated for instantaneous output (it can output 1A or 2A or whatever is listed on the charger, but only for a millisecond, then the rate will fall off).
Please use the app and let me know what your rates for wired charging are (not that the rates fall off when the device is charged more than 75%, so try to test when the charge is lower than that). I bet the rate you find will be lower than 800mA, but if this is not the case, I am curous on the charger and cable that you use.
As for the wireless charger, I know it is very very bad, am trying to return it.
A poor/cheap usb cable will make a massive difference too. I once had a cable that wouldn't let more than 384mA through it!

Exactly! This is why I picked the cable I am using now, but I could not get over 900mA with this combination of cable + charger. The Charger is a T-mobile dual USB 3A charger and in my opinion it is very good.
The stock wired charger is rated for 1.2A and actually charges at just over 1 A. The charging chipset in the phone limits charging to 1.5 A max.
The nexus wireless charger charges at 750 mA max. Bad positioning and cases will reduce wireless charging efficiency though.

I've noticed that during wireless charging my phone will charge at 500-600mA up until 85-87% and after that it will charge at 300mA to 100%, so make sure when you are testing to test at lower battery capacity. Also, try wireless charging from a USB port of a computer, I've noticed that I got better performance form USB port than from 2A touchpad charger.

Wired charging is always going to be faster than wireless charging. Wireless charging on the Nexus 4 Orb takes about twice as long as charging via the supplied wired charger with the Nexus 5. Technology is going to have to advance quite a bit before wireless charging eclipses wired charging. There is an inherent inefficiency with wireless charging that wired charging does not have.
i bough one of those white, skewed ones off ebay for 10€ shipped and am pretty happy with it!
Another qi charger. However, this charger is built with 3 coils instead of the standard 1 coil. This technology should negate the need for the phone to be placed on a "sweet spot" as seen with most other qi chargers. The only other charger I know of that has this technology is the TYLT VU which is a universally admired qi charger, but pretty expensive. Has anyone purchased this charger?

Can anyone recommend one? Or does it even exist? I can't find anything online.
Thanks
There is a 5v 2amp wall adapter - http://www.amazon.com/gp/product/B0...kCode=as2&tag=dcre-20&linkId=DB5ZD4J34NIWRZUR

From what I have seen and read, the most a Qi charger will output is 1amp
That link I posted is for those who have low amperage and having issues with Qi charger.
I was looking for a qi car holder, tho recent feedback on different models suggests 1a qi is not enough to actually charge the G3 while using satellite navigation software, due to the drain from the gps/screen/CPU. I found that using an old 0.8amp USB charger in the car lost a similar 5-ish% an hour when used for sat nav as when using an in car qi.

As hot as the phone gets on a 1A Qi charger I think you'd just be asking for a fire at 2A. I haven't found one either though.
I have this one and it's working perfectly.

we are talking about the Qi charger aka wireless!
I've been doing some extensive digging for a 2a Qi system myself. The highest available system is unfortunately 1a. BUT... In order to get the 1a, not only does the charger (transmitter) need to be rated for at least 1.5 - 2.0a output because of poor efficiency, but your receiver in your phone needs to be rated at a 1a output. This is why you see several people who are only charging at 600-700ma. For my Note 3, I have found a 600ma, 700ma, & finally a 1a receiver coil. The Samsung charging backplate is actually only rated at 600ma. Just make sure you look before you buy. I bought an Itian A6 charger combo and it only has a 600 also, but the transmitter I believe 1.5a. I'll just have to pick up another coil once my charger arrives. Damn China Post takes forever.
Anyway, hope this helps answer your questions. Wireless Consortium approved a medium voltage guideline and I just read that they have come out with a Qi system that is 97% efficient. Our power demands just need technology to catch up.

The heat is due to the inefficiencies, most Qi chargers lose 25% of the transmitted energy, which ends up being the source of heat. The newer 97% efficient chips will be much cooler. Also a good receiver coil is thermally protected and will shut down the charge at a threshold temp. The quality of the receiver coil is the most important part of Qi. But don't forget, charging any battery rapidly will cause heat as well. There was a news story about 2 months ago of a kid who slept with her phone under her pillow and caught fire from improper ventilation. If your phone is heating up that hot, you may want to remove any case it's in. Charging up with Qi and a metal backplate isn't exactly the smartest thing to do either.
Yes it does exist

well I'm also on a similar hunt..
the closest option i found was the google qi enabled pad for 50$ rated at 1.8A out
and not too sure about this because the website doesnt say much but the samsung one is 2A
Oops didn't see Qi Charger :X
According your description I don't think it exists. I believe the charging power not only depends on the charger, but also on the Qi receiver in your phone. If the receiver doesn't take more than 1A, then the charging speed would not have any difference regardless of you're using a 1A or 2A wireless charger.
Does anybody know what the stock LG receiver is rated at

I think the 2A refers to input, the output might be 1A also

My qi charger is a generic cheap one, its rated at 2 amp in and 1 amp out. I presume it only delivers 700mah cause of how inefficient wireless charging is, I was under the impression 1 amp was that max qi standards could handle at the moment?
Basically, if you want a reliable and fast charge then you can't beat a wired connection. I don't understand really what difference it makes from plugging in a cable on the bottom to placing it on a Qi charging mat/pod. From what I have read, wireless charging is not really good for ur battery and should not be a substitute for a wired charger.
If you get a good 2A charger it will charge the phone in about 100 minutes if you are not using it.
Did someone try Samsung S6 Qi Wireless Pad with LG G3?
I'm considering to buy it but saw on Samsungs website that charger is 2A and it is not recommended to use it with lower amp adapters because it may damage it....
The G3's 1.8A...
Will that adapter give any harm to Qi Pad?
Thanks for any reply
that"s why i find wireless chargers gimmick
why should i put a 2a charger in the QI charger too fùking output 1A why...
i have a wirless charger and its anoying cause u need to put the phone on in the right way. and it charger so slow i mean if you put your phone on the wirless charger pad why not take the usb cable and put it in... to get 2a fast charging. (and use a reversible micro usb cable)
Try qi infinity

dodocool Wireless Charger, Fast Charge Qi wireless Charging pad for Samsung Galaxy S7 / S7 Edge / Note5 / S6 Edge+ and All Qi-enabled Devices Black
I have a few Qi wireless chargers and a Qi enabled device (Nexus 6) but never use them mainly because they charge at a very slow rate but this dodocool Wireless Charger has Fast charging mode (Output 10W Max) which uses Quickcharge 2.0 so if your device has Quickcharge capabilities you will be able to take advantage of but if not the Standard charge mode (Output 5W Max) for standard Qi-enabled devices will also work. I can say I now use this wireless charger as my primary charger and even use it in the car and I know that sounds odd and did to me also at first after reading it in product description but the charger itself first off is angled downward which helps you to view your screen and most importantly the charger base has 2 silicon rings around it, one on the top and one on the bottom which help secure the charging base while sitting in care and the silicon ring on top of charger not only helps secure phone while on the charger but also protects phone from getting any scratches or wear marks. I must say I’m very impressed with the overall function and looks of this wireless charger and highly recommend it. As a special gift to my Facebook/Twitter/G+ and YouTube friends here is a 30% off Code to use at checkout from my friends at dodocool.

I'm looking for something other than the stock charger that will charge my Pixel just as fast as the charger that came with it. I've tried a few but none have come close to the charging speed of the OEM charger. Are there any specific chargers that anyone would recommend over others. Especially if it's a fast charging wireless. My old wireless Samsung charger wouldn't work at all.
iPad pro 2018 replacement charger should hit the same speed since it's USB-PD 18w
