Quick Charging USB Adapter... Any thoughts?

I am considering buying this usb charging adapter cable to help speed up my charging rate at work where I don't have an AC adapter and my work computer's usb ports are conveniently placed. From what I have read, normal usb charging maxes out at 500ma, but can be increased if your usb port has more juice if you short the data wires, which will tell the phone to grab more power because it thinks it is plugged into an AC adapter.
I have found this adapter http://www.dealextreme.com/p/usb-data-charging-extension-cable-for-samsung-p1000-black-91141
it is meant for a galaxy tab, but From what I see is that it has a switch that either allows data / slow charge or allows quick charging. I have purchased a few of these already because I'm assuming it will still work with my galaxy s2.
I'll let everyone know how it goes, but does anybody see a problem with this or think I'm going to fry my phone for any reason?
Thanks.

very interesting, heck it's only $3 bucks, might as well just buy it and find out
yes, charging via USB port sucks, it's too slow at 500 mAh
if that does the magic trick, by shorting it and making it believe it's an AC then it'll be nice, and it can pull around 1000 mAh off the USB port (depending on your computer mainboard)

Id be curious to see if this actually works but i see no fault in trying it

Only the Galaxy Tablets have this limitation (they cannot be charged at all via computer usb only via their "special" wall adapter) so the adapter won't do anything for a phone. The adapter works on the tablet because what the adapter is doing is shorting 2 pins on the USB cable to fool the TABLET into thinking it is on the AC adapter "specially made" for it.
As long as you plug the phone it into a self-powered usb port (ie: a hub with a power brick) you will get max current the phone allows. The adapter will make no difference on the phone because the phone CAN charge off the PC port while the tablet cannot. It won't hurt the phone but it won't help it either.

Thanks for the info on the galaxy tab, however I disagree with you in your opinion that an adapter that shorts the data wires will not help the phone to charge quicker.
It seems either the devices or android system itself limits charging to 500ma so it does not damage the computer, the phone itself knows that it is connected via usb, and will state "Charging: USB Plugged"
If you let the phone think it is connected to an AC adapter, it will allow the battery to accept whatever amperage you throw at it, and you will see that the system states "Charging: AC Plugged"
Obviously there are two modes of charging going on here.

Has anyone tried this yet?

I have found that using the Galaxy Tab chargers works the same way. They have a 2amp output vs the .5 amps that most blackberry chargers and USB use... It shortens the charge time significantly.

Charger considerations
Hi,
I need advise for the following:
Charger A (Li-polymer battery) output : 5V, 1A
Charger B (Li-polymer battery) output : 5V, 500mA
Device input: 5V, 750mAH (Li-ion / Li-polymer)
When using Charger A, some people comment that it will limit the current of 750mAH for the device and the device's battery should be fine since both the charger and device are at 5V. However, some people comment that this will shorten the battery life of the device since it will perform a 'quick charge' using 1A.
When using Charger B, some people comment that the device will draw more current than it can deliver and causes it to heat up and reduces the charger's life. However, some people comment that Charger B will extend the battery life of the device since it performs a 'slow charge'.
I also read that USB pins on the charger denotes if the charger is a PC or a dedicated charger. If it is a PC, the device will limit the drawing current. If it is a dedicated charger, the device will draw more current to charge itself.
I am confused as to who is right and which charger should i be using.
Can someone enlighten me ?
Thank you very much.

Automobile Quick Charging Solution

What is the best solution for quick charging the Galaxy Nexus in an automobile?

I have started to use 12-220 volt converter so I can use wall chargers.

I have bought a few of the low profile car usb chargers but they were never recognized as an AC charge. Come to find out, it was the USB cable. I bought a usb charging cable from Amazon last week and it goes in the USB charger and the phone does not think it is a USB charge. I have not timed it but it is recognized the same as the wall charger.

+1 .. this solution has been working great for me, as well.

I've been getting 2.1A car chargers (look for ones for the iPad), most of the ones I had prior to this were 700mA or so and they can't keep up with my 1A phones. Be careful of dual port chargers advertising 2A, they may only be 1A each and may be "optimistic" about that rating. And don't worry about getting one rated for too much current, the Galaxy Nexus won't pull more than an amp no matter what the charger rating.

Some really good solutions here and thank you all for the help.
I'd really hate to use an inventer in my car just to maintain a clean install, so that really isnt an option for me.
Was really hoping to be able to use a off the shelf car charger with the correct pins to trick the GNexus into thinking that it was charging from a USB port, but the above solution should work well with using a socket USB charger.

I've never run into a car adapter that looks like a USB port, including the VZW charger with a spare port or the cheap 2.1A chargers I got from Amazon. My guess is that a charger not built correctly and leaving the data pins open only supports ~500mA anyway. Even if that's not the case I have a moral objection toward buying a cable to fix a design flaw in another cheap product - but that's just me

I've got a charger similar to http://www.ebay.com.au/itm/USB-Car-...ccessories&hash=item4ab18358f4#ht_1638wt_1392
All I had to do was undo the screws at the top, put a bit of solder between the middle usb pins, and my phone recognises it as a AC source rather than USB.

There has got to be a standard car charger on the market with the middle usb pins already soldiered!
I found this on Amazon which advertises itself as a rapid charging device.

Make sure the charger has the IC (rapid) chip. I use this one:
http://www.amazon.com/Motorola-Vehicle-Adapter-micro-USB-Charger/dp/B000S5Q9CA

I've heard that Motorola one mentioned a lot as a good one.
The nice thing about having the low-profile usb plug is (a) it is low profile, (b) I can use it to charge other devices. The charge-only cable is only about $4, so I had no issues buying it to work with this to charge as an AC charge over a USB charge.

I have this one and it charges just like it does from the home outlet and its says "AC" charging. I bought another 8 for family and friends and they all love it.

I think I've figured out the disconnect, I've run into chargers that appear as a USB host which limits the charging to 500mA on previous phones I've had.
You guys are concerned about USB vs. AC charging mode. Of the chargers I've got, this one lists as AC while the rest as USB. However, the fact that the other chargers all work just fine keeping up with GPS+streaming music indicates that the USB vs. AC really has no bearing on the charge current delivered. I'd stay away from charge-only cables just because they'll get mixed in with your standard USB cables and you'll knock yourself out wondering why they don't work. On the other hand, if you really want AC in your battery info order the one I linked.

I keep it in my car... i think I've heard on other threads that USB charging doesn't keep up with GPS (for Directions). Any verify?

What's much more important is the rating on the power source. The GN can pull up to 1000mA, if your charger is only rated for 800mA (like many car chargers) it doesn't matter if it's in AC mode.

makes sense.. the one I use has dual usb (1.0 and 2.1)

You went and gave me a project for the weekend, and once again science prevails over anecdotal evidence. I took each of my 5 chargers and hooked them up to a 12V power supply that measures current. I then recorded whether the charger reported AC or USB, for the ones with USB I modified a right-angle adapter to short out the data pins, and I measured the current. The contenders:
Verizon Wireless Dual Charger
XTG Dual Port Charger
Griffen Powerjolt Dual USB Charger
Griffen Portjolt Micro
CostMad Dual USB Charger
The VZW model was USB out the external port as I had tested before, however AC out the built-in cable which I hadn't bothered to test. It pulled 0.25A @12V via the USB port and 0.59A via the cable. Hmmm... A hole develops in my previous observation. While I had used this on a long car trip with no issues, it was via the built-in cable.
The XTG was new, I hadn't used it before as it's in the car I rarely drive. It reported USB and 0.22A. With the adapter to make it report AC it pulled 0.48A.
The pattern was set. I had expected the Griffen adapters to be built more appropriately but the dual charger reported 0.22A without the adapter and 0.42A with. I had used this without losing charge in the past so this was surprising to me, but it's possible I just wasn't drawing as much current because the screen was dimmer or something.
The compact Griffen adapter (which is great for a laptop bag, BTW) pulled 0.21A and 0.47A respectively.
The cheap CostMad adapter was the only one that performed well out of the box, both reporting AC and pulled 0.57A.
In theory, a perfect adapter should pull 0.42A. Anything more is waste, anything less means it's not keeping up. I have doubts about the Griffen 2x allowing for a full amp, but the VZW and CostMad chargers are pretty lossy. What's even worse is that I'm pretty sure the VZW charger is rated for 800mA (but I can't find an actual spec on it) which would mean that it pulled the most power for the least current. Not that this really matters unless you've got an electric car.
Sorry for misleading you earlier, I should have checked the other port of the known-good VZW charger and probably doublechecked the numbers on my other "known good" charger. Still hating cables that work for charging but not for data, I ended up modifying each of the chargers to short the middle pins (except for the VZW one). If I didn't have the soldering iron for this, I probably would have gone for some of these instead.

I'm using the same one and it works perfect. Charges even when GPS navigation is running.
Make sure you select Amazon as the seller though. I heard there are a lot of fake ones.

+1 to those recommending this one. I have this exact model and it does indeed charge at the "AC" rate, about twice as fast as the "USB" rate.

Combo USB wall receptacle, 700mA or 2.1mA?

I was thinking about putting a new receptacle with USB and one outlet somewhere on my kitchen counter. Problem is the two better companies have two very different amperage's. Cooper is .7a and Leviton is 2.1a, both have two USB ports and one outlet. The charger for our E4GT is 1a and I also have a Galaxy Tab 10.1 that would need the higher amp version, but many have said to NOT use a higher amp charger than the one our phones came with, which is 1.
So what do you think? Is it really that bad for our phones/battery to charge it using a higher amp source? I know our charger cube is small but I also need it in various locations at home or at the office so having an outlet like this in my kitchen would be awesome.
I hate how slow USB charges our phones, so I assume .7 would still be kinda slow and not charge my tablet either.

http://www.amazon.com/Leviton-T5630...F8&qid=1350409796&sr=1-1&keywords=leviton+usb

My vote is for the 700. It will be better for your batteries over time.

Interesting thing that I have learned is that the Leviton version only pushes the higher amps on one of the USB ports. There is no where that states how much the one that gets less does though and I have read that if you plug in a device that does not need the extra amps that USB somehow puts out less amps and it charges slower.
I need to do more investigating though.

I agree to an extent.
I feel that it really depends on how long you keep your usb charged devices. Battery degradation may not be an issue if you upgrade often or are the type that never has anything older than the 2nd, sometimes 3rd, newest model device on the market. Also, a lot of the newer devices require higher amps to charge at a reasonable time. This transitions into charging habits. On the 0.7A charger, you may find yourself leaving devices on chargers over night potentially hours longer after fully charging. This is arguably also damaging to the battery.
Either way you go, you may find yourself with a bunch of 6' microUSB cables from devices taking forever to charge or battery degradation. :silly:

Your phone is only going to use as many amps as it can. Say a GS2 charges at 450ma USB and 650ma AC. The phone will recognize if its USB or ac and allow it to charge according to that. Its not going to charge faster on a 1a charger unless you root your phone and hack those parameters. Doing that is what will cause battery life problems, if not cause a complete failure of the battery and/or the device.. The higher you you set the charging amperage, the more likely you are to have problems.
And phones now (especially any model of GS2) have circuitry to prevent overcharging. Leaving your phone charging overnight is not going to cause any problems.
I don't know if USB wall outlets act like USB or a/c (think about a USB cable with a wall adapter) but plugging into the USB outlet and checking in the battery info in the settings menu or a battery app can tell you.
Sent from my SGH-I777

What's next wireless charger outlets?

Get the higher-amperage Leviton.
Your device will only draw the amps it needs. The GS2 will draw < 1amp. But if you have a big tablet, they can pull the full 2.1 amps.
Since you're doing a 'permanent' wall installation, you're somewhat future-proofing yourself.

Good info, thanks all. I did not know that our phone will only pull the amps it needs, so that is good to know. I may get the higher amp version because I have a Galaxy Tab 10.1 that needs higher amperage.

G5 charging slow on 99% of cables

Hey!
I noticed recently that my G5 charges quite slow. So I tested all of my powerbanks, cables, and wall chargers, in various combinations. I had 4 different powerbanks, 3 wall chargers, and 4 cables.
I used a USB ammeter to measure the power draw going through the USB cable.
On the motorola charger and cable that came with the phone, it charges at 1.8a. I then charged my phone from each powerbank and wall charger, using each cable in turn. The average charge speed for my phone was about 0.5a. Out of 28 combinations, only 2 yielded a draw over 1a.
I have created a spreadsheet detailing the charge speeds of each combination, but unfortunately cannot post it yet (10 post permissions).
I then charged my USB powerbanks from the same wall chargers, using the same cables. One powerbank charged at over 1a with every combination, and reached over 2a on numerous combinations. This proves that the cables and wall chargers are not at fault, it is a phone issue.
Why? Has motorola put something in their chargers that 'talks' to the phone, and allows for faster charge speeds? 0.5a is awful!
Secondly, does anyone know of cables that I can buy, which will support fast charging for the motorola? I have looked at genuine motorola cables, but there is no way to tell one from the other.
Thanks!
Paul
P.s. charge speeds were the same, whether the phone was switched on or off.

Welcome @agour
I've come up to a similar conclusion with a lot less data (thus I didn't share them).
I caught power consumption at the wall outlet when charging my device with two chargers: Motorola stock charger and a Samsung Adaptive Fast Charger.
The Samsung has the following specs: 5V 2A or 9V 1.67A with fastcharging capable device.
Using Samsung Adaptive fast charger and Samsung 1.5m cable : 6W, so the device charges at something like 5V 1.2A...
Using Samsung Adaptive fast charger and the cable provided with my XT1676 : 11.3W (which is coherent with the max 9V 1.6A, and would mean the charger provides 2.2A if at 5V which more than the specs.)
Using stock charger and stock supplied cable : 11.3W ==> fast charge for similar reasons as above
Using stock charger and Samsung 1.5m cable : around 6W ==> low power charge
I'd need a USB multimeter to confirm those data. (mostly due to the variable voltage that can provide fast charge adatpers)

Interesting! It's suprising how much difference the combinations can make.
I don't think I have experienced this on a phone before, however I have never felt the need to test it...
I tested the original cable that came with the phone, and an off the shelf 'genuine motorola cable'. The stock cable is still the fastest, however the secondary cable still worked very well.
Interestingly, one of my powerbanks will charge at 2.2a from pretty much EVERY powersource and cable combination. This is with 7 cables tested, and 3 USB wall adapters.
Shame that motorola doesn't allow their phones to draw maximum power from hardware that can provide it..

If I have some time, I may test internal impedance of the cables, it is possible that the device somehow probes the cable (or the cable + charger) and then decides if it can or not draw that much power without overheating/melting the cable; and then it will negotiate the quickCharge with the charger.
there has been a discussion about quick charge on this thread a while ago (before I got this devices : https://forum.xda-developers.com/g5/help/quick-charge-3-0-support-t3632457)

It is quite obvious that especially cheap cables will charge phones much slower as the resistance is too high, even if the phone does not perform any checks. Those cables are basically too thin. Resistance limits the current (amps) that can flow. Newer phones most likely just look at the charge current during the first x seconds (or less) and then decide wether to enable fast charging or not to keep the cable from heating up. A wire with high resistance is basically a heater. So it's a necessary safety feature (from the companies POV).
Regarding the power bank, it may be possible that this particular design provides a voltage slightly higher than the nominal 5 volts (still fine for most devices), which helps overcome the resistance. That is also the reason why the Samsung fast charger provides 9V: You don't need a cable as thick as with 5V.
Keep in mind that the USB specifications only recently got updated for such high charging currents, so it is advisable to use only the cable that comes with the phone as USB cables in general don't need to provide such high currents by spec!

That sounds correct, although my Samsung wall adapter is fast charge capable, and was provided with a cable (and not a cheap one), that basically can't be use for fast charging with the G5, that looks silly...

USB from computer and car charging really slow....

Hi Guys,
I have a thinkpad which has regular USB and also a fast charge USB port. They have worked fine in the past on other phones and I used to see at least 1 amp charge rates. (on the fast charge port)
Using either port on the 20 X I only get about 200 ma charging rates?
I'm using "Ampere" to get the charging rates, it is definitely charging slower than normal...
Have you guys noticed this?

Also of note, It charges really slow from my car as well. On the hour drive home the phone only went up 4%. (This is a VW using android auto)

I think all bets are off when your using 3rd party chargers. I think Huawei might have some official accessories that you may need to buy.

I have a bunch of phones and every single one of them charges at normal charging rates off my laptop and in my car, this is pretty strange...

Huawei uses a completely different setup from QC 3 from charger to cable . How does it charge with the supplied charger and cable that you received with your phone? If you buy extra chargers for home or car make sure they say they do Huawei "Supercharge". They are a little hard to find but they are out there. Make sure the USB cable is rated for 5a(amps)

I haven't even used the included charger and cable, but plugged in at the house I do see 2 amp charge rates which is great.
The downside is that in the car with android auto I can't really plug it into anything other than the car's USB and that give me a really slow trickle charge. This is where a bulk of my charging occurs since I drive for work so much. Basically I have never charged my other phones outside of the car, I just use android auto all the time and the batteries are always topped off. So not being able to charge from car or laptop is not a deal breaker at all, but it certainly means I need to start carry a charging cube around everywhere.
Just seems odd for such an expensive flagship phone to not charge correctly via USB like every other phone I have ever had.

Try the supplied charger and cable just to make sure you do not have a defective phone. When you plug in the cable to charge watch your screen. It should show your battery percentage and a short lighting bolt. Then in just a second it should change to a long lighting bolt and say super charging. If it does that you know your phone is charging correctly. Take your Huawei supplied cable and use it on your laptop and car and see if that doesn't increase your chances speeds.

I gave the original cable a shot and it still basically charges at 200-250ma from my laptop. Very odd indeed. Not even seeing the normal 500ma that you would get on a regular USB port. (Tried both standard and high charge rate USB ports on my lenovo)
Anyone else seeing this behavior?
