[Q] TYLT Vu car charging

Hi,
I apologize if this has already been discussed.
I just brought a TYLT Vu wireless charger. It is a very nice product, but with one major drawback that really put me off.
It doesn't have a microUSB port. Main reason I wanted that is to use it with my car charger. Is there an adapter that'll allow me to do that? It doesn't make sense to spend $30 on a car inverter.
Otherwise, from the official website, it says it needs Input: 12V / 750mA.
I know that the car batteries give a little over 12V. Can we somehow take direct input from that? Like cutting the provided charger and soldering the pin directly to the 12V car input? Will that work? What are the concerns/issues/problems with this?
BTW, the small pin type adapter, is it the same as old nokia adapter? I have one lying around somewhere. I can search by tonight, but if someone can confirm it before that, that'll be helpful. I can just cut the wires from that and not damage my original adapter.

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!!!

wireless charging solution thread

As we all know, the new Zenfone 2 is missing wireless charging capabilities, however there are multiple solutions to enable wireless charging on basically any phone.
Example is http://www.amazon.com/BEZALEL®-Wire..._1_4?s=wireless&ie=UTF8&qid=1432149451&sr=1-4
It is a cover with a Qi receiver built in, which connects to the charging port and it also provides an independent micro usb port as a part of the case.
The absence of wireless charging in Zenfone 2 is a deal breaker for me ( don't judge) and as soon as an appropriate case is available, I'll get it and the phone as well.
Please post your findings here.

Would love to use wireless charging but using a cover like the one posted is out of question.
I love the slim form and feel of this phone. so i will have to live without QI and other solutions.

This will occupy the mUSB port but would probably be the best current solution.

That's pretty cool. I like wireless charging because I'd rather not wear out my micro usb...but that setup kinda marries you to wireless charging all the time. I'd have to rig up wireless charging in the car and at work...not just at home. You use something like that?

Not sure if I'm going to stick with the ZF2, so I haven't gone out and done all that yet but qi adapters are pretty cheap now for both home and car. How effective some of the car ones are though are another story. iOttie has two models out now that look promising for the car.
There may also be the possibility of placing those adapters into a separate case just meant for wireless charging... remove the case if you need the mUSB port.]
Or... if they do release new back covers... get one that you install the qi adapter in and then one that you won't have the qi adapter in.

WHYYYYYYYYY
Why did Asus decide not to include the qi pins in the back ((((((((((((((((((((((((((((((((((((((((((((
>_<
what to do :'(

Here's a teardown: http://www.myfixguide.com/manual/asus-zenfone-2-teardown/
You could solder the DigiYes posted earlier (http://www.amazon.com/gp/product/B00HI8JYFE) onto the usb board. Or you could probably just jam the wires into the connector for a non-permanent solution. The pictures of the DigiYes are a little conflicting, but if it does have leads for the data pins, you'd be best off omitting them (you'll be limited to 500ma qi charging).
This is of course assuming there's enough space to wedge the DigiYes between the back cover and phone.

Which goes back to my point. Why did Asus purposdely omit to include QI/wireless charging pins on the back? It would had cost them hardly anything extra at all, and users could just have changed back cover to get wireless charging...

That one http://www.amazon.com/BLUBOON-Unive...2630&sr=8-2&keywords=qi+wireless+charger+1000 is 1000mA, if it does make a difference. But a case integrated receiver would be much better solution, if ever.

I bought that model. I have a Qi charger (used with a Nexus 5) hooked up to a 2A USB Adapter, and it barely charges the Zenfone. I do not recommend. Maybe a 2A receiver would work better.

It's ridiculous.... why did asus decide not to offer a wireless charging solution similar to the previous samsung galaxies/lg.
Have the pins for charging on the back, and let the user change the case to a qi receiver case or add a qi receiver pad inside. this is honestly the only thing that disappoints on this phone (((((((((((((

I just received mine and there is enough space in the back cover for the receiver to fit in, albeit with a small bulge. It does show my phone as charging even when just held up to my Moto 360 cradle; whether or not it's charging, however, I have no idea.

Thanks for trying. Did you actually solder or just plug it in the usb port? If you plugged it in the usb port, does the cover close without damaging the cable?
I'm asking because if that works, we could potentially design a slightly thicker but hollow back case that could hold NFC and the wireless receive without unnatural bulges.

It closes fine but there is a bulge and the cover is left slightly open.
Here's my solution. Doesn't look good but functional.

Yeah I judge, wireless charging its just another feature. A small battery, a slow processor or low memory now that's a real deal-breaker since your phone wont last a day, apps will run like hell and you will always have to micromanage just for things to run properly.
I'm way more pissed off at this phone not having a removable battery, not just because its a real deal-breaker during travel where I will be forced to lug around one of those brickish power banks but because Li-ION batteries have the lifespan of a mosquito. I already had 2 phones like that and the result was always a massive pain in the ass to deal with.
I rather buy a case with an extra battery than this thing

Three pins USB Board?
Hi there
Maybe some one knows, what are those three pins on the USB board, that are accessible without disassembly phone?? That should be connectors to charging instead of usb socket?

I have a qi charger built into my car. I do not like aftermarket charger added to the phone. So this is a deal breaker for me and will not consider any phones without buildin qi charger.

Looking to buy this phone and own a quick charging card like this. Is it possible to slip the card under the back cover (without a case) or will it cause it to bulge in too unsightly a manner?

It can but causes a gap near the usb port that I could not close. I would've run it inside if it didn't do that.

The speed of charge is 350 MAH ?? Is to slowly (USB PC charge normally 550 MAH)

Charge N7100 through wireless pins, but with wires?

Hi All
I am currently in the process of installing my Note 2 into my car as a permanent fixture for media and sat nav. It is now flush mounted in fibreglass in my dashboadd, charging through USB and audio through 3.5mm. I want to use my UCA202 DAC which will allow better sound, but crucially allow me to mix my main phone audio through it for handsfree. For this I need to be able to charge and use OtG at the same time. This I know has been done to death, but what I haven't seen follows...
It is known that you can retrofit an inductive coil for wireless charging but it's slowslow. My question is, has anyone tried hard wiring 5v from a USB cable DIRECTLY to the 5v pins inside the back.? Is this likely to work or will the hardware specifically expect to see resistances etc associated with a coil? If it does work does it fast charge? If over 500ma?
It doesn't matter if it looks dirty because it'll be hidden behind my dash. Just curious if anyone has tried it before I try and send my phone up in smoke
Cheers

Sorry can someone please move to Q&A. Not been here a while and didn't see the button. Ta

I don't think so. It is limited to 1A tops i think (can go higher, but 1.2A is already dangerous.), so Your best call is to get an OTG Y-splitter which lets you charge + otg at the same time, but i can't tell You im 100% sure about that (about 95% sure it will work, since my multimedia dock is basically same thing, but along with MHL and audio jack.

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.

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.
