I was looking for a wireless qi receiver to wireless charge this phone. I read some reviews online about some qi receiver charges so or got hot fast while its charges.
Any of you use or used wireless qi receiver to wireless charge this phone and works fine without getting the phone hot while charging?
the galaxy A50 does not support wireless charging.
I got one from Wish and it's support up to 1A current. Unfortunately it's not enough because the phone is discharging. With A3 2017 the receiver works well.

Wireless reciever not the pad.... maybe you know it as a usb c to coil adapter.

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.
---------- Post added at 05:45 PM ---------- Previous post was at 04:57 PM ----------
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

Anyone using wireless charging on the MI3? It's only possible with a receiver, btw, it's not built in.

I am curious has anyone tried using a wireless charging add on and know if it works properly?
I'm a writer for Qiwireless.com and I use my Mi3 with a universal wireless charging receiver to charge it.
I saw something here: facebook.com/MiuiCzechSlovakXiaomi/posts/10152284167068959
Manufacturer named Lencow doing this type of chargers for MI's. You can find the net for the price.
is it for real that mi3 supports wireless charging??

Note, WITH a receiver. A receiver is a piece of hardware which sits under the base of the phone, and is connected to the charging circuit. Just google the term.
You'd have to be really motivated to take your phone apart, just to attach that. Without considering the space that module would need vs the available space inside the phone, which is pretty slim to start with. Actually with a metal phone back, I believe the module would have to sit outside of the phone, between the plastic cover and the back - so the phone back would not be flat.
I have had a Nexus 4 with wireless charging for the last 2 years, and I rarely use the wireless charger I bought:
- charges slower than a wall charger
- if you pick the phone up - as we all do - you stop charging and additionally multiply the number of charging cycles.
Cables are not as cool as a Qi pad, but a Qi pad also needs its cable...
Anyway, out of the box, the mi3 doesn't do wireless charging - just confirmed that with my wireless charger
stupid!!! pls improve yourself bout the 'Electronic Science and Technology' knowledge~ don't ask such an idiot question!!!
Hey all,
For those who got their Note 4 early from AT&T did they pull a fast one like the LG G3 and rip out qi charging pins in favor for powermat?
Thanks!
My understanding of qi with the note4 was that it only was available with the optional case, and it's not built into the phone.
Wasn't built into the s5 either.

Can someone with an att note 4 pop in a qi receiver and see if it charge up? I have a bad feeling they went pma just like the g3.
It's Qi charger. I don't have the adapter yet, but others have pointed out that the contact points on the back match the Qi specifications. I just got my Note 4, and opened the back, and indeed the contacts are identical to my wife's S4
Just because it has the Wireless charging contact pickups, doesn't necessarily mean it will work with Qi. The LG g3 had the same contact pickups, but at&t disabled Qi charging at the hardware level, and made those contacts only work with pma charging receivers.
let say wireless charging works, will it still take advantage of the fast charging feature though?coz I don't think so

NO, wireless charging is a Lot Slower charging than with your USB cable and AC adapter for Fast Charge.
It supports Qi. I bought the official samsung back. I use it with a Qi charger I bought off amazon. Works great but due to bulk, limits my cases.
Wireless charging can be done if you buy a wireless charging battery cover and these have them built in also. A cheaper route is just buying these little wireless recievers and stick them in, you can get them cheaper on ebay (but my work computer can't access Ebay sites).
Wireless charging IS slower than normal charging, its all about convenience. I have a few around the the house and a couple at work. Most output .5 - 1 amp range compared to 2+ amp chargers and the included adaptive fast chargers.
The links are for example only, not telling anyone to buy anything. Hope this helps.
Hey guys,
Since the OPO has NFC I'm assuming wireless charging will work... What are some good and cheap wireless charging options?
Thanks!
NFC and wireless charging are two completely different things. You could add wireless charging via a universal QI receiver but that's it

Ohh didnt realize that! So would I just need a QI receiver and I can put my phone on it? Or do I need a special case for my phone?
You need a wireless charger receiver, you will lose the USB port, when you want to use USB you will have to take the case off and take the charger plug out.
Since it's pretty thin you can use any case, or none (Maybe not metal cases).
You also need a wireless sender, this is the pad that the phone sits on.
Notes: Since these are only 500ma (have not found a pad > 500) and with less efficiency (so its actually less than 500ma), it will take a very long time to charge the phone. I dont even know if its able to keep up with the power requirements of the phone if it's in use.
Powerbot chargers are supposed to put out 1000mah. I think its partially dependent on the actual charging cord plugged into the qi charger though

that is true. all parts need to be compatible to get a decent charge rate. i had a charger that put out 2amps and a cord that supported it too but most receivers put out 500-750mah which results in a slow charge. and i havent found a decent receiver yet either. Most of them are really finicky and need to have the phone placed just right on the receiver for it to charge.
Highest possible wattage for wireless car charger? All I see is 10watt. No 15watt+?
All the wireless car chargers seems to only have 10watt for Notes, looks like 15watt for LG phones. samsung makes a 15watt wireless chargers stand so thought this would be possible for car chargers.
has anybody seen a wireless car charger that will charge a note 10 with more than 10watts?
thanks in advance

Hey .. I tried some of car wireless charger with 15 W .
There is only one working well for me .. it's giving me fast wireless charger when it connected .
But you have to buy also car charger which is support QC 3 to deliver that power to wireless charger.
You can find it in Amazon : CHOETECH 15W Wireless Car Charger Mount,15W/10W/7.5W Windshield Dash Vent QI Fast Charging Phone Holder Electric Auto Clamping
i believe the xiaomi wireless car charger does 20 watt max. Check it out on amazon

well the charger is 20watts, but it won't charge the note 10 at 20watts
so 52$ to do what a $15 charger can do
