Has anyone heard of a wireless Quick Charge 2.0/3.0 external battery? If yes, please post where this can be bought.
Here's a wired one:
https://www.amazon.com/Anker-PowerCore-Qualcomm-Backwards-Compatible/dp/B01CZV9FUW
You could fashion a wireless one by attaching a QC wireless charging pad, but it would be incredibly energy inefficient due to increased heat loss. Why bother?
I've got one and I highly advise against it.
1) It gets REALLY hot, it can't be good for the battery.
2) It's considerably slower than cable.
3) You won't get as much high quality batteries as there's less competitors making them, the best batteries are not wireless.
I hope this helps.
http://www.banggood.com/Qualcomm-Ce...t-Power-Bank-With-Power3S-Tech-p-1062286.html is one I just bought - only got it yesterday but very nice build quality and my Note 5 registers it as a fast charger.
I was hoping there would be one selling in the market, but judging from your replies, i guess not.
There are actually those selling QI-enabled external batteries, that got me into thinking that QI-enabled Fast Charging should be possible.
RAVPower Wireless Charging Pad with 5,000mAh External Battery Pack for Samsung Galaxy S7, S6, Nexus 6 5 4 7
Even samsung is selling a QI enabled External Battery Pack for Note5.
Samsung External Battery Pack for Note5
I guess i will just make one. Thank you for informing me about the heat issue, perhaps a silicon or ceramic plate will be sufficient to insulate the battery from the heat.
Still, if you encounter any wireless QI Quick Charge external battery packs, please do post.
I don't know about wireless. Seems like a good idea but I would think it would be very inefficient.
I have the Anker PowerCore+ 10050 and I love it. It works so great that two of my family members got the same one. Highly recommended. I have to admit it does get hot sometimes but not to where I've ever thought it was "too hot".

Hi Guys,
Anyone tried Solar Powered Battery Chargers?
Looking at this one here :

I'm looking fior the same. I bought recantly GOAL ZERO Nomad -7. Instead of charging it drains the power of my Note-2. I guess it is because of the non-standard pin-out (11 pins), so this is the one I would definitely not recommend.

I haven't seen any positive reviews about any solar powered chargers. The problem is that you need to apply voltage (bias it) in order for it to work. Like those solar power panels on the roof of people - if you loose a power to the house, they will not work So they might be draining instead of charging lol!!!
Don't know for sure how it works and if it works and how efficiently. So if anybody has any real life experience, please chime in. Most of the big name external battery vendors don't want to carry this product. I only seen it on ebay and Aliexpress.
I personally haven't tried one. From what I've seen about them, they're very fast, and can be nick-picky about the angle to the sun. On top of it, you'll probably need to check what's the output versus what the phone needs to change.
I think you're probably better off finding some kind of crank mechanism and use that to change the phone. Plus, you'll get a little work out too; you'll live longer to enjoy your phone, 8)
I have a voltaic that I use when camping or on extended hikes. It comes with a 3000mah battery. I haven't used it on the Note2 yet, but used it a lot with my Fascinate. The battery works fine as backup power, though it charges slowly and the phone pretty much has to be off for it to be effective. It takes most of a day of full sun to recharge the contained battery. It's ok if you're going to be away from power for a week, but for less than that I think just an extra battery or two fully charged would work better.
I think we just need to find or build one that supports 2.1 amps (ideally) but anything over 1amp should do something.

I have one I found at Best Buy a couple years ago. It's a single amp box, so charges my Note II very slowly. I've used it on my bike when I'm out on rides. I have a mount for it and my phone. While riding, I use bluetooth headphones. It does work, but like someone else said, there needs to be one with 2.1 amps.
I as well have a Nomad 7, but mine charges my note without issue, although I will admit, it is impractically slow.
I bought this couple of months ago, charging the phone is a wii bit slow but it works like a champ!

I wouldn't mind if the solar power was a "backup" to a regular external battery, but if all it did was solar I wouldn't be interested.

WICKED... just stumbled across this on ebay. If you are a roll your own DIY type and want to charge a rapid charge device like Note2 or a tablet or something, this might be a great thing to look at.
http://www.ebay.com/itm/DC-DC-5V-36...018?pt=LH_DefaultDomain_0&hash=item2c700c47c2
I, personally, don't like the mini-usb connector... seems kind of goofy. I'd prefer just two wire terminals to connect solar panels to.
But yeah, if you've got high voltage solar setup... e.g. anything between 5V and 36V and want to have a clean, regulated 5V usb compliant output, this would likely be your guy. I'd also want to make sure it really does work with note2 - in terms of negotiation of currents higher than 100ma. YMMV FWIW
AND if you don't need note2/tablet 2A...
this guy seems like about the right fit.

I had a previous model of this unit which was at the old "slow" charge rate and was so pleased to get the new and improved version. They even fixed the few issues I had with the older version. This model has the charging cable in back instead of sticking out the side, the LED indication light is much dimmer, although larger, which makes it easy to see where to place the phone in a dark room and not act like a flashlight while trying to sleep.
The display angle is acceptable, it works well through a case, although I haven't tried a Defender case yet and the fit is more secure than even the Samsung charger..
The unit uses a microUSB connector and a 2.1A adapter, not included.

To anyone thinking of wireless charging for our device - I advise against it. Not only will it charge rally slowly compared to the standard charger - it'll generate a tonne of heat and kill your battery rather quick.
I use a cheap chinese QI pad and it doesn't get hot but I discovered you need to switch off fast charge (under battery) and it works fine. Granted it charges at a rate of 20% in 30 mins but for overnight it fine....mine doesn't seem to get hot or even warm.

I have used wireless charging since the Nexus 4 and never had any trouble with reduced battery life. Nexus 4, Galaxy S4, Note 3, Note 4, and Note 5. Except for the S4 which I returned to switch to a Note 3, the battery life is about 20 to 24 months with little or no reduction in usability. When I get a new phone I hand the old one down to my wife and other family members, and I have ordered the new batteries when needed.
Hello everybody and happy new year!
My original super fast charger which came with the phone won't magnetically charge my note 20 ultra
with the charging cable which I used with my Samsung note 8. I already ordered new pd 60w quality cables+new pd magnetic adapters.
Since I did not find any information -Do I have to buy new magnetic tips (which are stuck in the phone) or can I use the same tip which I used with my note 8? Are there any differences between tips?
Thanks for your help.
Eran
P.S - I am using my Samsung note 8 charger with the magnetic cable adapter in the mean time. The only problem is the slower charge....
If the previous setup didn't work for the new phone, you'll need the new tips too, most likely.
However, especially at the 25W fast charging speeds of the phone, I'd recommend you steer far, far away from magnetic chargers. Sure, it sounds like a nice idea, reducing the stress on the USB port, easy tear-away charging, and so on, but since most of these chargers are incredibly low quality, with bad contacts, you can expect a lot of loss, which manifests in the shape of heat. I remember with my Note8 I did the same, and the phone would get uncomfortably hot - and that was only 15W. Imagine what 25W would do.
The only magnetic chargers I trust are the ones specifically made and tested for the device - e.g. Apple's (old) MagSafe on MacBooks. And even those had heating issues.

The super faster charger doesnt play nice with alot devices iv come to find. I had an issue using a 2 in 1 charger/ aux adapter. The charger kept connecting and disconnecting. It seems to be some thing special to that brick specifically. Especially since its a 45w charger and I tried a ravpower 45w charger and it did not super fast charge my phone. Soo, yea. Super fast charging will only happen by way of samsungs official charger... which doesnt like alot other add-on devices (dongles, magnetic tips, ect).
Hi guys,
I've noticed Samsung S21 ultra supports 15w wireless charging - I was just wondering if all 15w wireless chargers were compatible? Or whether they specifically have to support "Samsung fast charge 2.0" - like the official chargers?
Wondering what others have bought? Let me know! Thanks!
I've been doing some research, I know that Samsung devices are supported by QC 3.0... but just wondered if this is true for wireless charging? Will generic 15w wireless chargers work? Would be much cheaper!
While generic 15w chargers will work, there are other factors that needs to be considered. Such as what kind of brick you are using with the charger and things like how thick the case you are using.
Sammy only have one 15w charger and that is OG stand. The other sammy fast wireless charger is 9w (input still requires 15w though)
Can't comment whether which 15w is reliable or not as they are 3rd party and varies from company to company.
A fair point. I guess if you use a QC 3.0 brick with at least 15w output - with a 15w wireless charging pad it should theoretically work then?
Be interesting to see which ones people find works for them!

Probably works but wireless charging is inefficient and needlessly raises the battery temp which is detrimental to its longevity in the long run.

An 8 W Samsung wireless charger does not heat up the S21 ultra more than the 15 W charger I have (this cames with my Note 9). I would think a 25 Watt charger would heat it up more. The reason I bought the wireless charger was for my Note 9 and now the S21 ultra is that my Note 9, despite considerable babying, is showing some issues with the socket (it often will show cable charging instead of fast charging and despite changing cables, cleaning out the socket with compressed air and a toothbrush etc). So yes, in general you are correct but socket wear must not be discounted.

I hear what you're saying about the port. I do a lot of partial midrange charges so 3-4 times a day isn't uncommon.
The biggest thing is not to hit/drop it when a cable is connected.
Battery or port assembly the phone needs to come apart...
I have a couple of these wireless chargers. Mine are an older version that don't have a USB plug at the charging pad (mine has a non-removable wire from the pad). I can't seem to find specs on their site now, but when I bought mine they claimed they were 15w. I only bought them for how they look. I personally don't care how fast they charge, I prefer slow charging for better battey life, I'll use wired chaging when I need something faster. I have fast wireless charging disabled on my phone. But I just checked it, if I enable it, it does say "fast wieless charging" on the sceen when I place it on the pad, and the time to full charge is a little quicker than with fast wireless charging disabled. Still not as fast as wired though.

So the best way to check this is to download Ampere!
Grab it from Google play store, install it, and then open it while you are charging the phone on different wireless pads.
You work out the Watts by using;
Amps x Voltage
Let me know how it goes!
Hello! I'm looking for a wireless car charger for my Samsung Galaxy Note 20 ultra. My Baseus charger (on the screenshot) broke after only a year of usage.
It has 10w output and so when the navigation is on it only helps keep the charge.
Sometimes Xiaomi 20w car charger is recommended but according to reviews it still chargers Note 20 Ultra with 10 watts, 20w is only for Xiaomi charging protocols.
Can you advise me a charger that is compatible with and can charge the device with more than 10w?
Just look in Amazon, there's a lot of them that offer different watts for charging, not expensive either unless you go with name brand
I am looking for one as well. I have two scosche magicmount chargers that are fast charge. The 9v 1.67A or roughly 20 watts, but these will only charge the new note 20 ultra at 10w. From what I can tell they start off fast charging then the phone stops them and only allows the 10w. I took one of these apart along with a Samsung branded fast charger, the biggest difference I saw right away was the samsung charger had dual coils. So I think that may be the difference the phone recognizes because the voltage and amperage are the same.
I'd like to find one that has the same or similar magnetic mounting system. Its mostly a matter of convenience but also I have used clap ones before, not all were wireless chargers but the manual one often broke on me and the one automatic one I have has a touch button on the side that is very sensitive, so it often releases when I don't mean for it too.
@adj998 Yes there are plenty on Amazon, but unfortunately it seems Samsung has deemed this single coil wireless chargers as inadequate and disables fast charging on them.

How has this Xiaomi charger fared? And how fast does it charge the N20 Ultra? The one I have doesn't charge the N20, just keeps it at a constant level but the same charger does charge an S7 and a Note 9 much faster (so probably coming up against the Sammie 'lets annoy customers by making them buy only Sammie wireless chargers' issue!). I have tried moving the phone up/down a bit to see if that's the issue but no luck.
So, looking to get something that charges faster and will get this one if it does so. Anyone else have the Xiaomi charger and is happy with it?
I am still happy with it, it charges my s23 ultra fast, the screen says fast wireless charging so, it is still good.
