    Default Quick Charge 2.0

    I'm surprised there is not more talk about this. I suppose it's because the phone did not ship with a 2.0 charger. However, I bought one on Amazon and Wow is it amazingly fast!!

    I didn't know they began selling them. Roughly how much faster would you say it charged, or have you not compared them?

    HTC hasn't released them yet, but you can use any 2a wall charger and the phone will charge with quickcharge 2.0

    Can you affirm whether the block or USB portion is what makes the charger quickcharge 2.0 compatible?

    The M8 supports Quick Charge 2.0, it's a combination of the processor chip and charger that makes it work.

    It's the processor that chooses either quickcharge 1.0 or 2.0. You have to have a wall unit that outputs at 2a and your processor will enable the quickcharge. You might need a specific cable too, but I can't confirm this

    I have a 2 amp charger in my car and at home. The difference in charging speed while notcible isn't as fast as I thought.

    Anyone have a link to the product (Amazon or otherwise)?

    How much faster is it really? I mean, the battery life is already really good on this thing, but a quicker charge would serve me well.

    Thanks! I understand the processor is capable. Just curious about the accessories part because I need a new car charger and just want to ensure if I'm spending money it's on a setup that will provide quickcharge 2.0. I my opinion it will be most beneficial in a 10-20 min car ride when I will not be using my phone anyways.

    Actually I believe the output 1.5A or 2A supports quickcharge 1.0 but the actual wall charger has to have quick charge "2.0" compatibility so that both the chip inside the phone and the chip inside the charger know to use "2.0" as the charging speed. The amps a charger outputs doesn't have to do with the quick charge technology. For example a phone that has 800 chip or higher will charge in "1.0" mode regardless of what amps the charger is because to charge in "1.0" only the phone chip is needed but for the phone to charge in "2.0" mode the phone and charger have to have the "2.0" mode compatibility chips inside of them.

    According to this press release:
    ...detects commands from a Quick Charge 2.0-enabled device, and adjusts the output voltage of the AC-DC wall charger to deliver increased power to the devices battery through a standard USB cable
    So, looks like the trick is increasing wattage by raising the voltage beyond the 5.0 USB standard. This is reasonable, as going beyond 2 Amps is pretty harsh on those tiny USB cables. That same article says that their reference chip can output 5, 9 and 12 volts at max 2 Amps. 12x2=24 watts. This is nice.

    Moreover, this other press release says that the standard supports up to 60 watts. This is pretty awesome. This means raising the voltage to 30V if you wanna stay at 2 Amps, or 20V if you raise it up to 3 Amps. I don't think they would dare to use 15V/4A - that would be too much current for the tiny cables.

    Here it says about wall chargers to be released in early 2014. However, where I really need speed charging is in my car. I cannot find anything about car adapters.
