HTC AC Adapter

Anyone know how to get my hands on a second HTC-brand AC Adapter for the EVO that plugs into N/A wall outlet? (MODEL TC U250)

Would like to know this as well since it works reliably and is high power.

I like the HTC branded one too for it's power and size but here is a really good travel charger to consider.

It has a battery built in so it can also function as a backup battery when you're traveling and need a quick charge. With a 25% off for being a premier customer it's $29.99.

I'm pretty sure I saw some on Amazon

I found a kit for the iPod and iPhone that provides a 5V/1A car and home charger that allows the device to work properly (no wonkiness with the screen). They're both USB plugs and then you plug in a microUSB cable that you've provided (it comes with an iPod cord). The phone doesn't unfortunately recognize them as anything but USB BUT they are higher current so they should charge faster than the typical devices.
It's made by Philips and says "Fast charging at home & in the car" on the front. The part number is DLM2264/17.
This is the same thing on Philips' website (though on this link it's branded DLO and the one I bought is not).

I believe it was $35. I found it at Staples.

i was looking for one too and found this seller on ebay: http://cgi.ebay.com.au/HTC-Desire-O...Accessories&hash=item255c9d25ac#ht_2798wt_733
they are OEM HTC models and dirt cheap (US $9 inc. shipping). just placed an order!

Enjoy waiting on that ac adapter for a month.

I've gotten two from Florida, took three days:

I bought this one, got it within 3 days. I am thinking about buying another one just to have.

Qi Wireless charging

Im not sure if there's been a new development on this or not but I didnt get find anything.
These Qi Receivers like:
http://www.ebay.com/itm/New-Qi-Wire...S_Cell_Phone_PDA_Chargers&hash=item4ac6c3197e
http://www.ebay.com/itm/Qi-Wireless...S_Cell_Phone_PDA_Chargers&hash=item1c3375487b
The qi wireless charging mod seems a little too complicated. Now that we have these receivers has anyone tried fitting one to the S2?
I know they arent made for it and there are special connect points in teh S3 S4 and the such but cant an end be splayed open and put in between the 1st and 4th connectors where the battery makes contact with the phone? It would be a little difficult to force fit it but it would be snug and not likely to move and fits over the battery well. Has anyone tried any of this?

Qi Wireless Charging
Hi, I just bought a Qi Wireless charger & Charging Cover and its pretty cool! I bought it from the Bitmore UK site.
They have a wide range of Qi (wireless charging) Devices and the one I bought for my S3 is universal. You can charge any qi enabled devices on this pad.
Just search for: BITMORE Qi Charger

Wireless charging

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!!!

[Q] AT&T Note 4 support qi charging?

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.

Is there a way to add wireless charging to this device?

Whether it be an internal wireless receiver or external usb c receiver. Most external usb c receivers are at the minimum 3.9" tall which seems to be the issue.

You can, but...

You can get an Ultra Thin USB-C Qi Wireless Charging Adapter, and you could install it on the phone and keep it hidden and in place by getting a Razr phone case. I plugs into the USB-C charging port and the thin flat ribbon cable has a 90 degree bend to it. I used this coil adapter before on a convention smartphone years back, the only drawback is that your USB-C on the phone will be occupied by the coil. Wireless charging is slower than traditional USB-C charging.
Cheers,

I'm aware of that but the issue is most of these are at least 4" in height which would cover the fingerprint sensor.

Find the shortest version, and if need be you can cut it to streamline it.
The ribbon cable has some flex to it, and if you use a heat gun you can bend the flex cable like an accordion to reduce length. You could also diminish the height of the coil pack by cutting it. Since the phone has a glass back, and your "sandwiching" it with a case, there is no fear of creating a short when charging.

Wouldn't cutting it cause it to malfunction? Also, do you mean use a heat gun to fold it in half? Do you have illustrations?

I think he meant to cut the edge to make the fingerprint reader completely clear, but not to cut too much to avoid the coil, and I'm assuming he meant to fold the cable in half.
Another point besides the charging speed is the heat that the coil produces.

Just a few questions. Where can the wireless adapter in this picture be purchased (link)? It looks like the usb dongle is too long to fit properly on the phone since the adapter is shifted below the fingerprint sensor. Does this wireless adapter work good on the device without overheating?

Link does not open... Please supply some info to find it

I see this for Barbuda nut only comes with lightning connector... would need USB-C ＆ only 5v so... I would still buy one at that folds its level because I don't really care if it's fast charges because I leave the thing on the stand overnight and it may actually be better for the battery to slow charge.

I played around with this as well. I was able to trim the one I'll link below to the right size. The key is to not cut the coil, the rest seems like it can be cut without a problem. In the end I didn't like not having access to the USB-C port. But it was a fun pandemic project.

As for the one I cited above with lightning connector... maybe someone here knows how to suggest they make one for USB-C ??

I'm a little late to the party here, you can solder in a wireless coil to the inside of the phone. The best coil I could find is this 7.5W (5V 1.5A) coil. There's a 10W (9V) option, but it would require addition circuitry to use in a phone.
The external plug-in solution is by far the easiest option, but it has too many flaws: blocks usb port, protrudes too much, fragile- must be kept inside a cover to protect it, most put out 2.5-5W, and it looks horrible.
Heres the link for the internal coil. If its unavailable at the time of reading this, on aliexpress, search for "7.5w wireless coil".
https://www.aliexpress.com/item/1005004119996834.html
And here's a youtube link showing installation. You can skip half of it. aim is to tap it to the ribbon carrying the charging from the usb.
It does require some understanding of basic circuitry and soldering... not for everyone.
Ive just bought the new Razr 2022, and will be installing it on that.

Just keep in mind that the RAZR has two batteries, and getting it apart isn't for the faint of heart.
It's also one thing to get apart, and another thing getting it back together..
Just advice, but definitely watch anything you can get your hands on before tackling, and good luck.
