Searching for dual qi wireless charging pad

Searching for dual qi wireless charging pad - General Accessories

First I thought to buy the Google one, but it just to small, and I need 2, for nexus 5 & 7, then I thought, why not to kill 2 rabbits, with 1 bullet, and buy a dual charger, the ZENS looks good, and big, so tablet not look out of place, any other recommendations?

You are not seriously considering buying that dual Zens charger for $100+? That is WAY TOO overprised. I just recently reviewed a single pad one from ravpower (search through a link in my sig) for $35 which you can just take side-by-side to make a dual one for much cheaper, and also will publish another review of DX.com small qi charger (the size of glass coaster) for $20, so it's even cheaper. Both were tested to work great with Nexus 7, and in my opinion a better alternative. Plus think about it, an individual qi charging pad (beside being cheaper), will guarantee 1A of charging current. With a dual one, I seriously doubt you will get evenly distributed 2A current split into 1A feeds, so you will end up with $100 big pad, slower charging, and no flexibility for a small traveling companion.
In my opinion, if your budget is $100, just buy 2x single pads similar to ravpower (you can find it on amazon or ebay from other sellers even cheaper, probably under $30), and tape them together for one pad that will cost you < $60.

I contacted ZENS, and they told me that, it do work with nexus 5 & 7 at the same time, I don't know the tech specs, so I'm waiting for reply, from them.
Also, my problem is the size if current single pads, and I don't need a travel solution, just good charger for home use only, they just too small, not in terms of, that they not work, but it not looks good with tablet, as they made for smartphones, the ZENS dual, at least have size, also, it not like those cheap Chinese one, it has multiple coils, and that important to know when talking about cost, also, I don't care to spent 100$ on it, because more and more devices out, with "qi", so it will be used with other devices, It's like laser printers, they cost more than inkjet, but they print and print more with one toner, so if you buy something, that will be used for long time, just buy the best you can,or at least with a good value for long time. As for the charger, I think it has 2-3A input, but has some circuit, that allow only 1A for each device...but not sure about it

Zens Wireless Charging Kit

Saw this article this morning. Thought I'd share it.
http://www.phonearena.com/news/Samsung-Galaxy-S-III-wireless-charging-kit-introduced-by-Zens_id32935
Won't be coming out until September, for about 85 USD, but at least there will be options.
Does anyone know how much the official one will cost?

anyone know how wireless charging compares to outlet powered charging as far as strength and charge time?

$85 to me just seems ridiculous for a wireless charger when the technology obviously doesn't cost nearly that much. I think even after these official setups come out that I will stick with the palm touchstone conversion if I decide I want to do wireless charging. Even if I mess something up I can buy and screw up 8 of those before I even get close to paying $85.

I agree, the touchstone cost less, but with the touchstone charging rate is only 500mAh which has slow charging time.
I'll like to see the official one first.

The Qi standard offers a maximum of 1A in low power mode but a lot of the ICs on the market (TI) only support up to 500 mA. 500mA is about half of dedicated wall charging one I believe and the same as when you plug it into your PC to charge.

I plan on modding a case to do this. I am currently looking for some schematics because I have a feeling that this was provisioned in the design of the phone.

1A is more like it,the SGS3 has a charging rate of 1A through the mains.
i'm not in a rush for one so i'll see bother before I decide.

I'm not too sure myself, but I've heard some people say it takes longer and others that say it takes just as long. I know when my husband had the palm pre and would use his touchstone it really didn't seem to be a very noticeable difference in time.

Does seem a little pricey, but would love to pick up one for my desk at work, grab and go when I go out on the floor.

It's new technology(For phones at least) so obviously they gonna rip off the early adopters, I mean I bought one for Nintendo DSI for £3 which has identical technology to what they put in that so I'm gonna take that apart and if it works just buy a cheap battery cover and stick it together.

If it is qi or compatible then the energizer charging pad will work. It is well worth the money imo. I used it with tbolt every night , before my slim, lean, toned s3 arrived. Now I just can't decide whether to ripe one of my spare tbolt qi doors apart or wait for factory s3 qi door.
For what I've seen if the palm is so easy why not use the "proper" dock and hack a tbolt or similar door.

Hopefully this combined with the Verizon version that someone posted some photos of will put some pressure on samsung to hurry up and release the official one...

Sonof the zens unit is $85 then the official Samsung one will be $100or more.

still no word on the wireless kit?

For overnight charging, this is a good thing - extends the life of your battery. The higher your charge rate, the less your battery will ultimately live. The performance of your battery overall will degrade. Slow charging is a good thing.
If you want a fast charge, just plug into a USB cable if you are in a pinch.
Also, I read in the Galaxy Nexus threads (where the Palm Touchstone mod originated) that there's a software mod they are applying to increase that rate up to be nearly as quick as the 1A charger. The same type of mod may be applicable here.

I just got my ZENS+Shield kit for the S3 that has the protective shield instead of the OEM-style backing. I'm loving it!
Previously I had been using an OEM back with a Touchstone wireless charger installed in it, but I really wanted to have my elago slim hard case that makes the buttons recessed. I made an ugly hack that made it work most of the time but I hated having to fiddle with those Palm Touchstone chargers and making it align to the magnet.
Sometimes my cat could get annoying and just nudge it or maybe the phone would vibrate enough from alerts, it would get into this "charge-discharge" loop state that can't be good for the phone, sometimes even fully lose contact. It was just not very reliable -- I found myself sometimes just plugging it into USB to get a better charge.
The ZENS wireless back fits really well and provides the backing I wanted. I wish the texture was a bit more grippy but it's not exactly slippery. It's on-par with the stock grip. It's a bit heavier and slightly more bulky than the elago case but that's because it provides a bit more protection and has a rubbery pad for some sort of shock protection.
The charger is great too. I can put the phone in just about any position and it'll charge. They even brag it'll charge if you put it on a high volume speaker in the instructions (but it may take up to 2 mins for it to "negotiate" in that case.) It seems to charge faster than my Touchstone.
It's Qi standard so I should be able to use it with any charging pad. I was shopping for a second charger but the 3-position Energizer looks much too big as does the Duracell and the single position Energizer is slanted and I've read some people have issues with it sliding off. I like that the ZENS charger is flat and the size is nice, so I ordered another.
There's one downside to the ZENS charger but I think other chargers (except the Palm Touchstone) suffer the same problem: they do not use USB as a power source. My ZENS charger uses some ugly wall-wart. Also it's a bit more expensive.
