I frequently use the usb cable to charge my device. Does anyone know of a solution that with increase the volts from usb to speed up charging?

You don't want to change voltage as that WILL fry your phone.
What you want is a higher current output (mA).
A computer usb won't do for this, so you'll want a wall charger. But you don't want too high of a current either. Just get one with a higher current than the stock charger.

Thanks for correcting me. The wall charger is what I guess I'm trying to avoid. I charge my phone via usb from my radio in my car but it takes far to long. Any ideas?

Unfortunately, that uses the usb spec which is 5V dc @ 500 mA. And there isn't a way to change that.
You'll have to get a dedicated charger of at least 1 A (or 1000 mA).

****ty, when i use the gps and charge it, its a wash. I guess im hiding a cig outlet in my dash somewhere. sounds like im doing a right up in the passat forum.
Newer Gigabyte boards offer USB ON/OFF charging, which offers slightly more than 1 A of current when the computer is off. But you can still use the port for charging.
My main concern is the usb connection in my car.

You can boost it, just use Ohm's law. Find the element(s) in the circuit and change them.

Well, I = V/R
A car's battery is 12 V. Use a multimeter and identify what circuit elements need to be changed and change them.

I'm pretty sure it's more than a resistor regulating the voltage at 5v. Also, it's not as simple as changing resistors, especially with surface mount devices. It would be MUCH easier to hard wire in a charger with at least 1A current output than mess with a usb connection that also could very well fry the deck.

It depends on your motherboard. My Asus has a feature on the USB 3.0 ports that charges about as fast as using the wall plug

I didn't specifically mention resistors. Circuit elements can be anything from resistors, capacitors, gates, etc.
Thanks for the input guys.

mine will merely maintain the charge while im using the wifi hotspot and have it charging off the laptop. not worth it to mess with the wiring in your car. luckily, i have 12v and 110v in my car so i have options
Am I missing the blinding obvious here? Why not use a car charger?

If u got 2 usb ports use a Y cable. 2ports 5v...1000mah .correct me if im wrong
Guys, what is the maximal output current? Will 1.5A fry the phone/battery? (HTC Sensation of course)

No.
The voltage is what will fry it.
A 1.5 amp charge won't deliver 1.5 amps all the time. That means it's capable of delivering 1.5 amps. The actual amperage is determined by the phone. The phone is only going to draw 1 amp.
What you want to make sure of is that the charger is a standard 5 Volt charger. The voltage is what the charger will deliver every time no matter what is plugged into it. If you have a charger fro a difference device that delivers 12 Volts, it will end your phone.

sorry for English not perfect. I am translating with google.
I have a car charger that marks OUTPUT 5V --- 650mA (max)
if i use this charger with the nexus one I run the risk of ruining the battery?
Or can I use it safely?
I think you will be alright in terms of damage, but you may want to look at a 1a charger or like a 900ma charger so that when you are using the GPS and all of that it can continue to charge instead of not being able to keep up with the draw from the device(what I am thinking will happen with the power output from the charger you mentioned.
I can try and better explain if I was too confusing, hope this helps

Where have you guys been able to find an adequate charger for GPS and normal phone use? Ive had trouble with this.
manual, in specification, is written:
Charges at 480mA from USB, at 980mA from supplied charger
What does this mean?
So my 680mA working? or not?
It will charge. Just slowly. And if you are using gps or streaming audio it may not keep up.

try nokia dc-10 1200 mah - can't beat that. Little on the expensive side but is retractable and looks great

the "quickcharge" port on it is 1a, the regular is 500mA.

Hope it works better than the Belkin "Quick Charge" USB car charger my wife has for her iPhone, I don't get a quick charge on it on my Nexus One. Middle pins aren't shorted I presume.

You're completely fine. I think the battery might get hot, so keep the phone in a somewhat cool environment.

as long as it is 5VOLTS it should be no problem, but that doesn't mean that your phone charges faster

I do use a 2A charger in my car because the 1A was overheating. I do always use the GPS in my car + mobile network and BT are always on.
The 2A charger can charge my phone (now) whilst I`m using the phone in the car.
The battery draws only the power it needs from the charger not the other way round so you can use a 10Amp charger if you want to without doing any harm to the battery.
It might actually charge slower as the phone could pick it up as a generic usb which will only draw half an amp so as not to over-draw a usb port. I believe to get full 1 amp charging the data pins in either the cable or charger have to be shorted (connected.)

Hello. Does anyone tried to use asus usb charger plus with sensation? I don't know how to make it charge faster. It charges as a regular usb port now (500ma).
You have to check if there is a short circue of USB connecter for data transfer.
If not, you may try to flash custom kernel which support fastcharge.

I'm using genuine HTC charger.
For original HTC charger kit, the D+ and D- of USB connector were shorted. In order to charge over 500ma, you need a good transfer wire. I've tried to use a cheap wire with original HTC charger, the charge current was limited in 500ma.
Basically, to obtain charge current over 500ma, there should be shorted circue in either charger or transfer wire of D+ and D-.

dont be mistake in the asus charging. only Asus AC power charging used 12v it'll be charging fast and quickest.
I got a charging for tf101 and I used it charging for any device, its incredible quick . full after 2 hours in used
I believe Asus USB charger plus is only valid for apple devices like iPhone and iPads. What it does is that it can charge those devices even when the computer is in deep sleep mode. It doesn't work with the sensation as I have tried it with my Asus laptop.
Correct me if I'm wrong as this is what I read on the web

I think you're right.. It works only with apple..
I have note2 right now which have to go. But I'll keep my office charger which is 2A.
Can I safely use it to charge n5?
Sent from SGH-i317m
Using chargers with a high power (A) is no problem, the phone will not "take" more than it needs.
Sorry for the poor english ^^
The issue is if charging IC can handle 2A current or not. I dying wanna fry it lol
I would think it should not be an issue while 2A ICs are widely used in our days, but "better be safe then sorry".

While AFAIK there's no 1.5A ICs, than its 99% safe to say they using 2A nominal IC.

If using a different charger was a problem they would have made the connection something other than micro USB.

Not really. Charging current depends on IC installed, not the connector itself.

From what I understand, you could use a 10A charger and still be fine. The handset will not take any more than it needs. Basically, the charger doesn't push current, the phone pulls it.

Thats correct and nothing else. No way to destroy a phone with too much A because it just takes as much it needs. The 2A on an charger is just the maximum power output. It is physical impossible to PUSH the ampere in the device.
Im curious if I can use the extraordinarily large USB cable from the nexus 7 coupled with my m8s wall plug and get the same charging speeds from the higher amp charging wall plug? I only ask because HTC makes some pretty short cables and hinders my internet browsing at night abilities :good:

Length of dc wire will lead to voltage drop. Lower voltage means the unit will draw more amps to get the same wattage of power. If anyone needs a longer cable make sure it's not cheap and that it uses a heavier gauge USB cable. Unless you are fan of heat in both your charger and phone.

Yes, but we are talking a foot or two at most here; the voltage drop would be inconsequential.
