HTC Fast charging ?

Hi,
I just stuck here, cause I found a thread about fast usb charging. But there is no answers or solutions.
I have many htc devices. It seems that some of them has a problem with 3rd party usb chargers.
My most used device is Universal. It suck a lot of power. THis one doesn't enable usb charging at all, until you put it in sleep mode before pluging the charger.
Anyway, the same issue for Kaiser too.
The problem is, that it doesn't matter how much current is the charger able to deliver. They just use some kind of recognition of original chargers.
What I already measured: Original charger and universal running => takes 1200mA. 3rd party charger or my 5A PSU => Universal/Kaiser sucks just 500mA.
This is fast/slow charge. I found here discussion about 4 and 5 pins shorted??
But WTF which 4 & 5 pin?
http://www.tracyandmatt.co.uk/blogs/index.php/2006/09/10/htc_hermes_usb_connector_pin_config
According to this pinout. It would be 2 GND of Audio side? I'm not sure that original charger use extUSB audio side to charge...? It also could be D & A pins, but I'm afraid to connect 5V to Data- pin.
Anyway, someone here have to know it.
If not, in a few days I'll try all possible combinations and post the results.
Thanks
Shef

I'd also be interested to know about this. When I charge my TYTN II via USB, it takes much longer to charge than if I charge it via the mains charger (I prefer USB since I travel a lot and it's one less charger I need to carry around).
Better still, is it possible to buy a USB cable that will charge at the same rate as the mains charger rather than messing with a USB cable with the associated risks?
Best,
Gary.

a usb port only supplies 500ma, while the wall charger does 1200ma as the OP has measured (although it says 1A at the back of the charger). changing a cable is not gonna superpower up your usb port.

unless maybe you get hold of a forked USB cable, like the one that Seagate Free Agent drives come supplied with... you know, 1 mini USB splitting halfway down to two normal USB plugs.
Worth experimenting with, do you think?

good call.......with a little googling i came up with this
http://www.universaluk.com/acatalog...2_x_Type_A_to_mini_B__USB_2_0__1m__Lindy.html
tried ebay, my brief search came up with lots of unrelated results, so i gave up

I got one of those leads, came with my portable 2.5" hard drive. Just tried the lead on my Tytn 2 and it does charge almost as fast as the mains plug

Success
Ok, so, I tried to experiment.
Here you go.
Usb simple cable 480ma charge.
The same result with Motorola charger.
Motorola charger pins A and B short circuit - 890mA.
That's much better, althrough I suppose it can suck more current then 890mA, but it's significantly better.
THere is also pins data+ and data- short circuited (I don't know if it has effect, but I can't disconnect it in this connector).
Apparently NC (not connected) pin on our pinout schematics definitely is connected.
With % of charged battery it suck less and less current....I suppose it's usual, this should be even driven by ROM.
So, update your cables
It works even with car charger, so no more charger problems...
Shef

Just to be clear - you took a Motorola USB cable and shorted pins A and B (which are which by the way?) and it provides a decent current....
How do you short the pins? I've looked in the end of cable and I can hardly see the pins, let alone short them! What's the trick here or have I missed something?
Thanks,
Gary.

Also interested in how to short the pins. I use Navizon, bluetooth HSDPA tethering, and iGuidance while on the ambulance and even my iGo 3A max rated charger can barely keep up because the tilt wont accept all of the available current.

So have anyone found a way to fast charge our ppc through usb??

Yes, that is correct. Short pins 4 & 5 (4 is normally NC) to enable fast-charging. If you do it correctly, the phone shouldn't pick up tethering, and therefore should not say "PC Connected" or the like..
The TracyAndMatt pinout is wrongly numbered. The pin assignments are correct, but the number/letter scheme they used is incorrect. True ExtUSB pinout translation to their pinout is as follows:
T & M Real ExtUSB
-------------------------------
Pins E D C B A = 1 2 3 4 5
Pins 1 2 3 4 5 6 = 6 7 8 9 10 11
The way I remember is that the corner opposite the angled one is where pin 1 starts (where E is on the T&M pinout) - and they go like most IEC-standard connectors, in a clock-like circular numbering scheme.
Here's a better pinout: http://pinouts.ru/PDA/htc_extUSB_pinout.shtml
Hope this helps!

its the milliamps that is the problem even doubling up with a y splitter does not do much Find a charger with the most milliamps for a faster charge 1.2 amps works best and as far as i know no usb port puts out that much even if they are wired in a series. Many try to sell lower amp chargers they dont even know about it at att. if the screen is off they will charge but not well these phones are energy hogs. I must have at least twenty chargers and messed around with them... the original or one of highest amperage works for me.

Check winhlp.com/node/855 for the answer.

Is it possible to get one of the 'fast charge' enabled USB cables on eBay or elsewhere? I am not keen on doing the mod described.
What is the maximum mAh recommended for HTC devices? Is it still 1.2 A or more?

Check http://winhlp.com/node/855#qaes for the only buyable solution I know, besides compatible chargers. Your best bet is probably the original HTC charger, available for roughly $10.

There can be no recommended maximum mAh. There can only be a required current, which differs from device to device. Check Ohm's Law. The device determines how much current it draws. If the charger cannot deliver that current, then the charging process can fail in various ways, all undesirable.

USB to Power Outlet adapter?

Where can I buy more of the little adapter that you plug the USB cable in to, then plug the adapter into to your wall power outlet?
I'm planning on coupling it with this cable: monoprice!com/products/product.asp?c_id=103&cp_id=10303&cs_id=1030307&p_id=5459&seq=1&format=2
My Incredible charges MUCH faster when plugged in to a power outlet than it does when plugged in to USB.

I just bought two off of Ebay that I will be trying out. I will let you know if they work which ones they are. I do know that the one from Monoprice.com doesn't work well so I would avoid that one.

Ok I got a few of these:
http://cgi.ebay.com/ws/eBayISAPI.dl...&_trkparms=algo=LVI&its=I&otn=2#ht_500wt_1182
"PLO" brand "Powerbug" - meant for GPS devices but they work perfect with the incredible. 5v, 1A, 5watt (same as stock HTC charger). I got two at $8 each so not bad. They are nice looking compared to the generic Monoprice usb charger.
EDIT ** Don't think these have as much power as the stock charger. Spare parts states "Charging (USB)" when using these, so it's like being plugged up to a computer. Still a good deal at $8

The usb to wall plugs from monoprice are no good. I ordered several before I knew better. None of them worked properly...or for Any longer than 20 minutes.

Have you actually got it and tried it and it works? I did a search on Best Buy's website and they have them but they're $27! If yours works, I'll snag a few off of ebay before people realize how useful they are and jack the price up.

Powerbug description says mini-USB, Incredible uses Micro USB B...good luck. Let us know how they work...

I use a Boxwave Versa Charger. Plugs into mains or into car DC power outlet.

It sure does, however, if you take a look at the picture, its simply a USB slot that the mini-usb cable plugs into, which means that any USB cable could work as the OP asked about. I'd say this would work well. However, I grabbed http://www.griffintechnology.com/products/powerduouniversal and it works great and I can just move my cable from my car to my house and have power everywhere.

don't buy aftermarket USB A/C adapters unless it's just for an overnight charge. You can't use the screen when using an aftermarket adapter. It's quite annoying. every single touch screen phone I have had has this problem.

Yes I bought two and both of them work fine. Not sure if they charge as fast or not as the STOCK charger, but they are rated the exact same. The only thing I don't like about them is they have a blue light around the USB port. I found those at $8 each which is a lot better than paying $30 each somewhere else. I found these in another thread and the person was finding them even cheaper at some discount store I had never heard of. I'll leave one at work, one out in the garage or somewhere. The HTC charger will stay in the bedroom.

That's not true. While the monoprice wall charger DID have a screen issue, the screen works perfectly fine with these chargers. And I used all kinds of chargers with my previous HTC Touch and never had a screen issue.

I have several aftermarket USB AC heads that work just fine with the Incredible. All of them purchased some time ago.

I've been using my old iphone power blocks without any problems, though its only been a couple days if charging.
Depending on the price, you may be able to snag some fairly cheap with all of the companies that make cheap iphone/ipod accessories. Unfortunately I have enough power blocks so I don't have a need to buy/test any others.
I would be curious about other peoples experiences though.
Sent from my ADR6300 using Tapatalk

I have some Ipod AC adapters as well. I was thinking they'd be safe to use since lower amp for the Incredible... but what of the reverse? Can you use the Incredible AC wall block safely on other devices? It's 1A instead of the .5A for Iphone/Ipod.
I'm trying to travel with less charges!

Nexus 7 Car Charger

I was just wondering if anyone here has spotted a Nexus 7 car charger? Does it not matter if it's not specifically made for the Nexus 7? I'm trying to find one to buy online and I'm having some troubles. First post here I think I came to the right place though. :laugh:

Clicked thanks on accident lol. Any USB car charger should work, but I would make sure you grap a 1 amp one just so it has enough output to charge the tablet at a decent rate.

probably better with a 2amp one. samsung makes one for the tab2, about $12 on amazon, and just use your own microusb cable to connect to it.

Yup, go with a 2Amp one. Most of the cigarette lighter usb chargers are 2.1A.

Avoid the cheap Chinese 2+Amp car chargers, they can be so badly made they cause enough interference to wipe out your FM radio.
/edit 1Amp will be fine but don't go lower, the N7 would likely burn it out.

FYI I tried a 5v 1a wall charger and my gnex7 said f u wouldn't take the charge. 2a or nothing I say

Do you already have the Nexus 7? If so, can you take a look at the charger and see if rated at 1A output and/or try to charge it with a charger that came with your phone?
I am just curious if it can actually charge with less than 2A. The charger listed in the Play Store outputs 2Amps and I thought most tablets require 2A to charge.

Still waiting, should only be a couple of days now though...

I know this is something most people never do...but if you read the manual for the Nexus 7 it says you can charge it on a standard USB port with the Nexus 7 in sleep mode (no doubt because the power draw is much less). Standard USB ports are typically .5A...sometimes less. I would say that's the actual minimum. For the fastest charging 2A is what you want though.

The ASUS charger that comes with the N7 is rated at 2A (10W). I tested an old BlackBerry 0.85A (~4W) micoUSB charger and it seemed to work fine and the N7 didn't complain though I didn't do any scientific tests against the charging rates.
The 0.5A (2.5W) chargers probably won't even charge the unit if you're actively using it.
Cheers,
Kermee

Yeah...read my previous post...the manual says you can charge on a standard usb port (0.5A sometimes less) but only if the Nexus 7 is in sleep mode...ie you're not actively using it. If you can't charge it while connected to USB and it's in the sleep state...then your usb port is probably a low power USB port (<0.5A).
For those looking for a good backup battery charger for it...I recommend this one: http://www.amazon.com/gp/product/B005NGKR54/ref=oh_details_o05_s00_i00
works perfectly with my Nexus 7 (just make sure to use the correct USB out port on it as only one of them is 2A)

DealExtreme Charger
Saw this one on DealExtreme, even come with cable:
http://www.dealextreme.com/p/car-ci...-port-for-google-nexus-7-tablet-146751?item=8
Will be ordering will update when arrives. Also they're carrying Nexus 7 Cables in Pink, Green and Orange.

Was using a Sprint micro-USB plus charger (model PVX8823) with attached cable and standard USB port for 2nd device that I was using for my phone. Output is 0.65Amp which isn't sufficient and will slowly drain the N7 battery while in use. ~$35 at Sprint retail store. Wouldn't recommend for obvious reason.
Fortunately, had a spare Motorola SPN5400A 1Amp I bought with some screen protectors from Amazon because it was cheap like ~$5. 1Amp is sufficiently to maintain the charge while in use at near worse case running 3D games like Dead Trigger, Shadowngun, etc. So, 1Amp is minimum threshold.

You need a charger that:
1) Is capable of 2A (1.5A may be sufficient, 1A is a little too low)
2) Shorts D+ and D- together - This rules out most iPad chargers.
If it says it is made for iPod/iPad it will not work without modifications or adapters.
Samsung tablet chargers will work.
If you take an iPad charger, open it up, and short D+ and D- together, it will work.

So are any of these confirmed 100% to work? the one a few links back (GTMax) says works with iphone, and I thougth that meant would NOT work with N7. So I am confused on what will work, and I am already on my 2nd Nexus7 being I blew out the USB trying a bunch of differnt chargers for the car.
I would like something that is small and can have multiple USB plugged in, but not a show stopper, just hope to find something on Amazon (Prefer Prime) so I can oder with my case today. Really want to use this in the car more (GPS\GoogleMusic..ect.), but with no power not a great option.

Charger Behaviour for Nexus 7 on Griffin Dual USB PowerJolt

I have this Griffin Dual USB PowerJolt Car Charger and its been working perfectly on all my devices, Playbook, Blackberry 9900, Samsung Galaxy S3, iPhone 3G, iPad 2 and many others but for some reason, this charger just don't want to work with my Nexus 7. I don't know why its so picky and wondering if you guys could help me identify the problem and preferably with a good working solution.
I tried opening it up and follow the advice from http://www.amazon.com/gp/customer-m...m_ciu_pdp_images_0?ie=UTF8&index=0&isremote=0. Both pins are already been soldered together but the Nexus still isn't charging!!
This makes me wonder where's the USB standard? How are some device / chargers so picky? What did the manufacturers do to prevent charging on other devices or charging through a non compatible charger?

Thanks a lot. I did read up all the posting regarding the USB charging issue on the N7 but I still can't find the answers. I read about people having the Griffin PowerJolt and not able to charge their device.
After downloading the Battery Monitor Widget and plugging to my Griffin PowerJolt (short D+, D-), the device is charging (estimate: 384mA) but still not showing as charging. It shows Discharging and Unplugged. I don't think its the USB cable since the cable works on my PC.
So what causes this issue?

It doesn't matter why, just that your Griffin does not do a good job of charging. If you want more either buy oem or any charger designed to work with Samsung, those devices should work better.

Yep, the Nexus 7 is picky. No question about it. But your chargert *does* charge your Nexus 7, the Nexus just doesn't indicate it's charging.
Personally, I bought two KMASHI chargers from Amazon. It's a 5V 2A charger and it works great. Charges at greater than 1Ah and the N7 indicates it's charging. Won't charge an iPad but it works for me. The one I bought is http://www.amazon.com/gp/product/B008XQYH1G but it shows as unavailable now. I suspect the other KMASHI chargers will work the same, though.

It charges it but its slow. Being rated at 1A, its can only charge at 300mA+ so its rather disappointing plus the charging isn't consistent. Sometimes when I plug in, it will charge, sometimes not so its another disappointment. But I guess I quickly adapt it and don't bother too much now.
I can still use my in car Head Unit with a build in USB port. At least I am getting 400mA+ and it shows as charging so I am ok

Ive been recommending this Sprint 2A dual usb charger to everyone. Its a OEM charger so you can expect a high quality product that works as it should and it puts out the required juice to rapidly charge the N7. It also has the added benefit of doubling as a wall charger. Ive had mines for about a week so I can confirm it does indeed work! http://www.ebay.com/itm/130712043019?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649#ht_1459wt_1399

Hey All.. I looked forever to find a solution. The Targus 2A car charger has a small (3") adapter cable that comes with it purportedly for Galaxy Tab. That little cable with the data wires shorted on the device end allows the N7 to be charged from ANY 2A car charger. I'm using the adapter with a Scosche dual 2.1 Amp Car Charger

Edit: I just built a usb cable with the data wires shorted on the Nexus end (cut, strip, short micro usb end green and white, remake connections red to red and black to black, insulate splices individually, wrap all in electrical tape or heat shrink for strength and beauty) and it works with all chargers. Took about 20 minutes.

I had to try to connect the charger to my phone using a standard female USB-A to USB-C adapter and it worked perfectly.
So to answer your question, "There is, sort of, just buy the adapter you need and use that [emoji846]"

Looking for something I can use with longer existing cable. Don't understand why they supplied charger with attached cable. My S3 Frontier charger has socket.

I think that I read somewhere that the reason there is no plug supplied with the charger is that "most people have lots of chargers already". But also I guess it is a way for us to hand over even more money.
I have not tested this fully but I bought a new, third party, charging cradle for my Gear S2 watch and I would guess that stand should be able to charge the watch 3 also as it is a bit bigger than the original Gear S2 cradle.
Tho I have not really looked into the specs either the S2 cradle or the Watch 3 charge pad.
