I'm interested in the OP6T, but the proprietary fast charger is a problem.
Above the extra cost for replacing all my existing chargers, there is the issue of size and weight.
In my computer bag I have a dual-port charger with one port with QC fast charge for my Samsung phone, and one high-current regular for charging tablet or other things. In my suitcase I have a 6 port USB charger with two QC fast charge ports and 4 others for charging miscellaneous devices.
Fast charge is important in the travel scenario, as often there is a short time available to recharge devices while changing flights.
I have searched for a multi-port Dash-type charger and cannot find any. Only one of the ports needs to be Dash fast charge.
All I can find is single port chargers. Not really appealing to have to carry a separate charger, and then have to find two outlets, or carry an outlet strip too.
Has anyone found a Dash Charger with more than one USB charging port?
I don't fast charge any of my devices, including my 6T, however I will say my 6T draws the same amount of current from any charging brick I plug it into as my tablet. So it will charge pretty fast still plugged into a higher current charger, despite not being hooked up to a Dash charger. Just remember there are limits to what a USB cable can handle.

My question is "are there any Dash chargers with more that one port?", but you do bring up an interesting point.
My understanding is that Dash Chargers put out 20W (5V at 4A). Can you quantify "pretty fast"? Do you have a USB current meter? If you plug your 6T into a standard (non-Dash) charger or a battery pack, how much current will it draw at 5V?
For others - I'm still looking for any Dash chargers with more that one port....

I have a USB car charger that doesn't seem to charge as quickly as I would like it to. I say that by comparing it to previous phones and the rate at which they charged when plugged into it.
I read that you can short out the Belkin or Griffin USB charges to make it look like your phone is plugged into the wall. I'm not agains doing this because i like to tweak.
The question really is, I see that Proporta has a 4000mA (2000mA per port) dual port USB charger available. Will this allow my phone to charge like it's plugged into the wall or will it still "look like" I'm plugged into a USB prot charging?

Not exactly sure what you're asking, but I assume that you mean that a wall charger charges the phone faster than a car charger.
Unfortunately, I don't know if this is the case. USB is a universal standard with specific power requirements. Although there are medium and high power chargers out there, I would be reluctant to get something so extreme. I think USB calls for 500 mA standard, so I'd be careful using the charger you mention. You might want to do some more research on it, or contact the company about it.
I'm not an expert but my opinion is that usually USB-Wall charger supplies up to 1000 mAh (written on power supply transformer) while the USB-OutPC is only 500 mAh, in fact, I've noticed that the full charge of my Titan takes double the time if charged via PC.
Not sure about the amount supplied by cars USB adapter.
...my two amperes...
Some of the chargers accomplish support for things like the iPad 2 by shorting the two USB connectors. Some advertise things like 2000ma, but fail to deliver much more than 500ma. I am not sure if this is due to the choice of shorting out the data connectors to trick your phone in to thinking it is plugged in to the wall.
Back in the WM 6.5 days, you could accomplish this at the phone driver level and did not need to modify your chargers.
I would not worry about trying something rated higher as your phone would regulate the current. I personally intend to do my experimentation by shorting out the cable rather than the charger (cables are more easily replaced). Unfortunately, there is no app for WP7 that can measure the charging current, so the only way to do this scientifically is to use the battery status app and measuring the charge rate over time.
If you do the mod, post back and let us know. When I get around to the USB cable experiment, I will post back as well.
I've got around 4 different micro-USB AC Adapters that I have lying around. One is the OEM Lenovo, One is OEM Samsung (i777 charger + Samsung Micro-USB cable), one is a multi-USB port AC adapter with a micro-usb cable, and the last is an iPad 2 wall charger with a micro-USB cable.
ALL of the chargers except the OEM Lenovo ones don't charge my tablet. When It's plugged in, for a couple of seconds it says Charging (AC), and then it just switches to discharging. I've tried all the aforementioned chargers and cables in different combinations, and the ONLY ones to work correctly is the Lenovo combo.
Is there a specific reason to this? Also tried all 4 cables connected to my PC.. They all don't charge efficiently at all.
look at the Voltage and Amperage of the adapter !
Lenovo use 2A if I remember well, the other use only 1A
quyTam is correct... most USB chargers are between 500mA and 850mA. The dual battery design of the tablets requires a min of 2A to charge correctly. This is why most computer USB ports will not charge the device.
However... the changer isn't the only thing restricting the power. The cable you are using can also effect power. Not all cables are created equal.
I stopped by Staples just after getting my tablet and picked up a 4 port 2.1A USB wall charger. It will charge my phone, Bluetooth, and tablet. There are also really nice 2A "extra battery" devices out there that allow you to a charged battery with you that will power and recharge your device.
I also recommend the dock for the tablet... it has a 65w power supply and charges the tablet in a 1/3 the time then the usb chargers.
where to get a charger
i tried 2Amp chargers....didn't help/
my brother says:
"the pins are slightly different/off/longer/shorter/what DID lenovo do here?"
as a safety i bought:
http://www.ebay.com/sch/?_kw=886605022780&_clu=2&_fcid=100&_fvi=1&_localstpos=&_stpos=&gbr=1
just in case...
it costs an arm and a leg for a microUSB charger, but not charging the device for a couple of days would cost me more :S
just another things that makes the TPT slightly less then perfect

Charger
I use a Dell Axim x51 charger and an LG cable from an old phone. Seems to work very well and eBay prices for the charger are less than $4.
http://rootzwiki.com/topic/8523-rev...arger/page__st__40__gopid__448194#entry448194
In my experience a 1A charger will also work. Nothing less than 1A will do anything.
I keep my Lenovo charger in my home office and use a 1A phone charger next to my bed for overnight charging.
I too have a 4 port mains to USB charger: 2A but I thought it was distributed to the 4 ports. If all were being used then each port would only be .5A.
Will have to try it out. If it works it would lighten the travel load of chargers.

That's for sure. I thought the dock was a waste of money until I forked out on Amazon. Saves so much time it isn't funny....

The tablet needs to see 5.3 V, when using >500mA.
Already thinner USB-Cables increase the voltage drop
so the thinkpad wont charge, even with the original charger.
It may have less to do with your charger than with the cables. I bought extra long (6 and 10 ft) USB cables for charging phone and my TPT. The 28AWG of any length won't charge the TPT. The 24AWG 6 ft and 10ft cable *will* on a 2A charger. I haven't tried other combinations. I believe it will charge on a 1A charger as well, but would likely require the larger 24AWG cable.

Design Flaw in Thinkpad Tablet prevents Landscape Mode Charging for Developers
I actually sent my 1838-22U in for service, thinking that there was a hardware problem preventing charging while connected via USB. At first I had noticed that while connected directly to a PC via USB for development purposes (no docking station), the unit indicated that it was charging. However, it seemed to be discharging faster than it was charging and slowly worked its way down to unusable. Lenovo Tech Support indicated that they had heard of this happening, and that I should send it in to have its system board replaced. I sent it in only to find that all they had done was replace the battery and reload the firmware. I did notice, however, that when I connected the USB cable, it appeared to go into charging mode for a couple of seconds then switch into discharge mode. I asked Tech Support about this and they said they this was actually the way it should have been behaving all along, and that this was by design.
The User Manual (see attachment) states only that it might not charge, and that it will only discharge if the tablet "exceeds USB 2.0 power limits" (i.e. 500ma).
Well, the Thinkpad Tablet seems to be pretty good at doing that.
Here's where I present to the development community a conundrum. How can one develop in landscape mode while charging (even slowly)? In portrait mode, one can use the accessory docking station, which uses its own charger and charges through the proprietary connector next to the micro USB port, while separately allowing the USB to be used for data. In landscape mode, there is no such option. I will accept that the unit may draw too much current to charge well via a 500ma USB data connection, but then Lenovo should provide a optional charger that connects directly to the same proprietary connector used by the docking station. This is done elsewhere. For instance, Motorola realizes that the Xoom draws too much current to charge via a USB data connection, so they don't even bother with it - they provide a dedicated charger connection and charger.
==UPDATE== 25-May-2012
SOLUTION FOUND
The solution to using a data connection and charging the Thinkpad Tablet at the same time, without relying on the portrait-mode-only Dock Station, is to connect through a powered USB hub which supports the USB Battery Charging Specification (with a Charging Downstream Port). The specification provides at least 1.5A, which quite handily satisfies the Thinkpad. I found such a hub, the GWCTech HU2V40, on Amazon for $15.99.
If you get this model, note that only one of the 4 ports can be used for high-current charging. It includes a tiny "Smart Charger Adapter" but which appears to block the data connection (at least when when used with the Thinkpad). In other words, ignore the little black passthrough adapter included with it, and plug directly in as you normally would. The instructions don't explain the purpose of the passthrough adapter.
Hi everyone!
I just wanted to ask this: I just bought a 90W charger for my laptop. It is a "Targus Compact Charger for laptop and usb tablet"
It charges my laptop and also has that usb port which charges through a cable, compatible devices. Only that on that usb port, it says that it charges 2.1A, which is a lot. My phone charger does only 550mAh.
So the question, shouldn't I charge my phone through the adapter?
Thanks in advance!
Anyone find charging the Z3TC painfully slow? It takes me 6+ hours to get to full charge using the magnetic connector. Is it faster over USB? Is there anyway to see how much current is actually being drawn without root?
I'm charging using a USB wall wart, 5V/2A rating.
while charging, go to settings/about tablet/status and look what battery state is saying: "AC" means normal charging while "USB" says usb charging. The latter often is usualy limiting to 500mA. This would mean that your wallmart charge or your cable has the connectors wrong so that the device thinkgs it is on a normal pc-usb port.

3:50 for me to fully charge on magnetic stand.
magnetic charging
I also experience the same thing with the magnetic changer but when I use USB it does change it faster
I've noticed that as well! That it takes over 6 hours to charge up. It's very mysterious as to why though. I have the usb cord connected to a 5v/2a rated wall adapter, that takes forever to charge it with. Anyone know why or how to get it to charge faster?
So I ordered a bunch of stuff from ebay and amazon and am going to try a few things over the new few days to figure out the slow charging
1). charge using 5V/2A wall wart through a "charging" micro usb cable. This is one where the 3 data pins are not connected, only the 2 power pins. I have a rooted htc one m8 that can measure the charging current and will make sure this setup is capable of >500mA charging
2). same as above but use a micro usb to magnetic port adapter
3). charge using the official DK36 charging dock(not designed for the Z3TC as far as I know, it came with my xperia z2 phone, but the tablet fits in it and charges)
Since theres so many links in this chain(wall wart, usb cable, dock/mag port connector) I figure its worth seeing if one of them is a weak link
So I've been able to test out this nice USB car charger from Choetech Official with Qualcomm 2.0 charging capabilities. And I must say this lil thing works very well. Charged my Nexus 6 up from 15% to 73% around 45min. It's a well built charger that has smart technology for recognizing what kinda devices you have plugged in.
Has a dimmed LED that changes from blue to green when you plug up a fast charge device.
It's a dual USB port charger.
Input: 12-24V
Output 1: 5V 2.4A
Output 2: 5v 2.1A/9V 1.7A/12V 1.3A
I really like this unit. Works better then the crappy one i used to own by Qmadix. That one always seem to stop working after 2 weeks of use.
[Quick Charge 2.0 Car Charger]CHOE 30W (with Most Powerful QC 2.0 Port) Dual USB Car Charger with Micro USB Cable(White) https://www.amazon.com/dp/B00YX7Y3G8/ref=cm_sw_r_other_awd_GxKlwbPTT27F2
PS. the Choetech C0046 does come with nicely built 3ft USB cable.
I received this charger couple weeks ago and have been using it. The charger arrives in a nice package with the standard accessories. Inside it has the charger, the usb cable, instructions manual, and a pamphlet that ask if you're happy with the product or not. Pretty standard nowadays. I got the black charger but they also offer it in white. The charger is shorter than my other ones which is a plus for me. I don't like them to stick out of my car port since it's really close to my shift knob. The charger comes with two usb ports. 1 is for quick charge 2.0 for some phones like my galaxy note 5. The other is a normal port that charges pretty fast too, up to 2.4 amps. You can use either ports to charge your devices and they will charge to the max allowed but if you have a quick charge 2.0 enabled device, it's best to use that port. They colored the port blue for fast recognition which is nice. I don't have to fiddle around with it while I'm driving to figure out which port it is. The quick charge can charge my phone from 50% to close to full in about 45 mins. It takes longer if the phone is being used. I use the charger daily during my drive to school. I always charge it up to 100% before I head to class so it can last me all day. I was worried that by using quick charge so often, it would deteriorate my battery life but I haven't experienced that yet and hope I never do. When I use the charger to charge 2 devices, they both charge at their max. My phone charges with the quick charge while the other phone charges with the other port and it doesn't affect each other, which is very good. I really love this charger. If Iphones had quick charge, I would buy this charger for everyone in my family.
Choetech also was nice enough to allow me to test one of these charger for them.
I found it to be an excellent charger.
I have copied my review from amazon here for the fine folks here at XDA.
I will try to answer any questions you may have, just post up a reply or send me a PM.
--------------------------------------------------------------------------------------------------------------------------------------
This is a great little charger, and I do mean little.
The size actually surprised me a bit considering this is a 4 port charger.
I expected this to be a huge block sticking up from my 12v car port, but it actually is a nice small charger.
I have 2 port chargers that are bigger than this is, enough about that, on to the review.
Looking in the package you will find:
The Choetech 4 port Quick Charge 2.0 certified charger
3' USB cable
Instruction manual
The USB cable is one of the best ones I have received with a charger in a while.
It is not thin and flimsy like you usually get.
The charger itself is made of a nice gloss black plastic and looks and feels like it will hold up well to years of abuse in your vehicle.
This charger does support Qualcom Quick Charge 2.0, meaning that it will auto adjust voltages and amperage to best charge you compatible device as quick as possible.
In testing I found this charger to be able to charge my LG G4 and Samsung Galaxy Note 5 in about the same time as my other Quick Charge 2.0 certified wall chargers.
This will also charger non Quick Charge 2.0 certified devices at the maximum rate they will allow.
I tested my LG G3 that is not Quick Charge 2.0 certified and will max out at 2.1a charge rate.
It got 2.0a charge rate from this charger which is great.
There is also a blue LED on this to help you find it easier in the dark.
The LED itself is dim as to not be distracting,
I have attached some pictures showing how small this charger is and me using it to charge multiple devices including 2 phones and a GPS unit.
I have had zero problems with this unit and am glad to have it.
I would recommend this to anyone with a car or truck and either multiple devices they need to use daily or a device that is Qualcom Quick Charge 2.0 certified.
If this review has helped you at all, please click thanks below to let me know.
I received this at a discount in exchange for an honest review, this does not change my opinion of the product in any way.
Hey guys,
I got to use this charger too. Having 4 ports, one with quick charge was really handy. I was able to charge my Nexus 6, Nexus 9 tablet, and an iPhone 5S all from the same charger without having any drop off in charge rate from any of the devices I could measure with Ampere (Nexus 6 & 9). Overall, there isn't much more to say that the other guys above didn't say.
Other thoughts:
It's really small. This thing packs a lot of power for its size.
It is scratch and finger print prone, but I plan on leaving this in the car all the time; so that doesn't really affect me.
The charging light changes color based upon normal charging (Blue) versus quick charging (Green)
NOTE: I was given a discounted product in return for an honest review. All opinions and statements are my own
I grabbed the 2-port charger at 10 bucks a couple of weeks ago at Android Police.
I wonder why there aren't dual QC 2.0 ones out there.

probably grabs too much power and the design to make that might be too complicated without having some power fall off? Personally, my phone is the only QC device i'd worry about and the rest could take the slower charging. But that's my 2 cents.
I have this charger, too, along with a number of other CHOETECH products. Their quality is top notch with affordable pricing!
I have this charger in white so it sticks out surrounded by all the black leather in my car, but that makes it easy to spot and I keep the white charging cable in the quick charge slot so I know which to use when my phone is low. It doesn't seem to charge fast while the phone is in use, but it does charge quickly if you just leave your phone idle and let the charger work its magic.
Even you didn't have a quick charge device, it's handy to have a two port charger. I'm happy with that product.

Am waiting for my new Pixel phone when i got i will fill this thread by all the tests
It doesn't seem to support qualcomm's quick charge even though the chip has qc 3.0 capabilities. It uses USB c fast charging with Google's 18w charger.
No chance it will support Qualcomm Quick Charge as that technology breaks USB-C requirements.
No quick charge....
Is there anything wrong with using a QC2 charger with the pixel? I have one in my car from my old S6 and just swapped the cables. Seems to charge quick and without issues but I hope I'm not doing any unseen damage.
I was charging with the main google's 18w charger using the 'otg' and the usb 3 cable and the results was from 0% to 100% ~1.20hrs and just removing the otg from the charge and using the usb type C on both side the charge from 0% to 100% was ~40min..
Hi,
I will get the phone in the next weeks and i'm still trying to find good 3rd party charger as pixel in my country is sold without the original one.
Any good 18W chargers that you know that might work?
