Usual Car charger vs. USB Car Charger

It is not a secret, that charging over data cable is slower, rather than over electrical plug. I think it is due to USB max current is 500mAh, while my direct charger output in 1000 mAh.
I wondering if the same is relevant to car chargers. I'm having the one of so-called USB Car Chargers, which has the USB plug as output, than you connect it to your phone thru the data cable.
If I buy a usual mini-usb car charger, would I get any benefits in charging speed?
Thanks.

usb max current is 500ma on the spec, you can draw much more than that over the copper.. as long as it's not being regulated by "compliant" circuitry/drivers, you should be able to draw 1000ma

Ive been looking into this tonight, and I checked my GF's iPhone wall charger (which is basically a wall USB charger) and it outputs 1000ma as well, and ive found a few usb car chargers putting out 700, 800, and even over 1000ma... only problem i have is i need it to be compact... i currently have a 500ma one in the car but that didnt seem to really charge the phone...

The reason I am asking is similar:
When I am driving with gps and 3G turned on my phone is never fully charged. In fact, it seems it even uncharging a bit. I am wondering if the same happening with usual mini-usb car charger.
And if I want to buy new on ebay, they never specify the mAh parameter.

I bought a 1000mAh USB car charger for a couple bucks at monoprice.com.

Good car charger to buy? Phone dock?

I heard there is a difference between car charger. Some charge faster than others. I just bought one off ebay for 5 bucks. Damn thing charges maybe 10% after 30 minutes in my car. My nokia n95 car charger changed the phone from dead to full in 45 minutes and that battery lasted the same if not longer than the nexus one.
Also which phone dock should I buy, now that you can't buy a google/htc dock. I want one that is visually appealing.

This Motorola charger has been great. I can't remember how much its rated, but I think around 850mH.

Use this one too and love it

i use Griffin's. it has 2 usb, so it's good for charging my ipod and n1 at the same time. the bad side is, i think it don't have enough energy to charge my n1. it only slows the batt consumption. i use it a lot when i go for travels because i use my n1 as gps.

It makes sense to get the official N1 car dock. It's a sweet dock that can also be used to plug the charger directly into the phone.

I love my N1 car dock use it as a GPS and mp3 player. Charges ok while I'm drive and using all the features.

Is it ok to use a car charger rated at 1.2 amps? Do we need exactly 1 amp or 960 m amp?

The phone draws whatever it wants. The rating on the charger just says what the charger is capable of outputting. The official nexus car dock, for example, uses a cigarette lighter adapter which is rated for 2 amps while a usb cable plugged into your computer is only rated for 500ma.
The problem with buying 1A car chargers is that the phone may not know how much it can draw and will default to taking just 500ma. Every charger has some sort of way of telling the phone what it can supply, such as shorting out the 2 signal pins or putting a resistor between them. every manufacturer has it's own standard and it's a guessing game as to whether it will pull 1A or 500ma. Iphones, for example, will not draw any current at all unless it sees the exact set of resistances across the 2 signal and ground pins which is just silly.

Qi charging

What Qi-charging options are there for the xperia Z5?
Any chance that Sony will release something similar to WCR14, or are we stuck with fitting generic receivers between the phone and a case?

As I know, z5 doesnt support wirelless charging out of the box

Yeah, exactly, no support for wireless charging. However, Sony has released cases with built-in wireless charging for earlier models of the Z-line
and I was wondering if anyone knew if they are going to release a similar solution for the Z5 Compact.
At the moment it seems as though the only viable option is to install a qi-receiver bought on ebay or a similar site and pair it with a case.
Not so bad i guess, since it probably is a hell of a lot cheaper and you get to choose whichever case you want.
Awaiting my Z5C now and will update when I have installed a qi solution.

That is impossible becouse that cases before have connection over magnetic charger and z5c dont have it.

Okay, bummer..
I thought they might solve the problem of the missing magnetic port by using the micro-usb connection..

Just wanted to confirm, I purchased a Qi Wireless Receiver that connects over USB - no dice. They don't have the "teeth" that microusb ports have and due to the water proofing the port doesn't turn on.

Just wanted to post to say that this is wrong. What it needs to work is a connector has the data pins to be connected so that it shows that it's capable of outputting higher than 500mA. I'm using the Zoer receiver that has that and it works fine. Amperage is between 260mA to 770mA depending on the qi charger that I use.

no, not really. This qi definitely works.

You just need one with 4 pins instead of the cheaper 2 pin ones. I have one which definitely works. Unfortunately, xdadevelopers doesn't let new users post links for some reason, so I can't help anybody with the link to the one I use. I spent a lot of time working out what to use and finally went into a 'retail store' to test the one I ordered before ordering my own z5 compact. If anybody wants the link to the ebay item, just email at [email protected]. Make sure you choose the 'A type' for the z5 compact. Works a treat. There is a lot of confusion about qi on the z5. Some people are saying that it is because of its waterproof attributes, you can't do it. Not so. This works perfectly and once on, can be used with any QI standard charging mat.

Guy, anyone tried with the quickcharge wireless pad yet? By the way, do we need to have quick charge supported receiver coils in order to use the quick charge charging pad?

I've never seen a quick charger receiver? I gave up on this in favor of quick charging at lunch

For those that have gone down this route a couple of questions please:
1) How has the QI receiver lasted if the phone is submerged? Did it just need rinsing in clean water and drying out or was it screwed?
2) Is there a maximum thickness to the case which I should worry about?
3) What sort of time does it take to charge up?
4) If I'm playing music or video will it charge quicker than I'm draining the battery?
Thanks!

I just got this one:
ASIN=B01E15W2ZA
and it works good with my Xperiy Z5 Compact. It charges with about 600...700 mA, something les than with a normal charger, but absolutely enough for my purpose - modt of the time I just want to recharge over nitght. It goes up to 100 %.
The included power bank feature can also be used via Qi, but probably smarter it to use it with a cable to not waste Your capacity as heat.
By the way: Even NFC works through the receiver!
But still I folded the receiver cable twice to position the receiver on the lower edge of the beackside of the phone. This way I avoid the risk, that NFC sensitivity gets reduced and I can line up the phone better on the charger, because it must lay quite exact on the cross.

i have qi charger for 5c and it works. i order plate fro qi and qi charger from ebay. just this qi sticker must set under some case. another way it is possible to broke it.

Can you get an magnetic power cable and adapter for the 10.5" ???

I have seen them for the S2, but the S2 has an flat edge as far as i can see where the microusb sits, when on the 10.5" the edge is angled.
This will eliminate wear and tear on the microusb port once fitted, and you can connect the charging cable to the tablet with your eye closed, just about anyway.
Has anybody see one, below is an link to the S2 version XDA page.

To charge my Tab S 8.4, I use one of those two-piece magnetic charging systems. In my case, I use the system sold as Wiskin and other names. You snugly insert a tiny adapter into the Tab S's micro USB port, then charge it with a special cable that works just like Apple's original magnetic charger. It works great. I have five of these cables: office, kitchen, car, bathroom, and beltpouch. The system claims to charge as fast as 2.4 amps, but I suspect my Aukey 2.4A smart AC adapters are throttling that because I've never seen a charge rate beyond 1500 mA, even when the Tab S's screen brightness is set at 1 percent and the tablet is idle, drawing 300 to 400 mA.
I also use one of the adapter inserts in my Sony Smartwatch 3. I plan to use a third in my VicTsing bluetooth headset when the headset arrives.
Having ruined two Sony phablets by physically inserting and removing standard cables, I absolutely love these magnetic chargers.
The charging cables are available in different LED colors. The first cable I bought uses a blinding white LED, even when it's not connected to any device. I keep it in the bathroom, where it doubles as a night light! The second adapter uses a soothing green LED; prettier and more soothing than white, but it, too, illuminates even when not connected, giving you no way to confirm with a glance that your Tab S is charging. The third through fifth use a soothing red LED that's normally dark but illuminates when charging. That's more like it. The red ones were claimed to turn green when the device is fully charged, but mine don't. Oh, well. I've also seen, I think, blue LEDs, or green-changing-blue, or red changing to blue. Check Amazon and eBay.

oh.. this is nice features... i wonder if i can find it in my place...

Just received my magnetic adaptor and cable, as can be seen from the photo in the previous post you get 1 cable and 2 microusb adaptors, It take quite a bit of force to insert the adaptor into the micro usb on my 10.5" but this is so it does not come out easily, it does come with a tool to remove the adaptor.
I have the "Samsung Galaxy Tab S 10.5 Inch Unicorn Beetle Pro Full-Body Protective Case" on my 10.5" and the magnetic cable works fine with it, there is just enough space, and the port cover almost totally closes, good enough for me, all seems fine on day 1
My 10.5" seems to charge at full speed with this cable, the cable end has an charging led on it, I dont know if this goes off as i rarely charge my tab to 100% to preserve the battery.

It has a little bit to spare as far as sitting in the holder goes. It works for me, I've had complements on it, although it *is* cheap, because it is clear it does not look cheap, it comes off easily and suits my purpose.

I simply use one of these with a QC2 charger plugged in. It is technically for the M8, but the M9 fits as well. It also has a removable insert to allow for a case as well. Search around, it was only $16 when I bought it.

The problem is that these docks have its own condensators etc. (lets say power supply) which normally don't let "pass" the voltage of QC2. QC2 goes up to 12 V, the normal docks allow only 5 V.
Are you sure you get QC2 voltage with this dock?

Why would they bother with that? It would cost more.
Out of curiosity I just cracked it open. Nothing but a wire connecting the female plug with the male plug. I haven't put it to the test lately but it would charge quicker than the standard charger when I was using it frequently.

Great to see, thanks a lot.
Maybe some do it to be sure that the phone gets the right voltage with a wrong or damaged power supply, or if the power supply is included there is more space in the dock. I don't know but had some that are only for 5 V (also stood at the power port).
