Questions:
1. Is an 18W charger the same as a Quick Charge charger?
I have a Nexus 6 w/ 2 quick charge (2.0?) chargers.
2. Will those charge my (hopefully soon) new Pixel 2 XL?
3. Will they QuickCharge the Pixel 2 XL? Or just normal charge.
4. What's the difference?
5. Is there any difference between a USB-C to USC-C cable vs. a USB-C to USB-Normal cable as for charging this phone? meaning, do i need to get a car charger, external battery, etc, that has USB-C inputs?
Thanks for any input!!!
1. Not necessarily. QC is a specific technology developed by Qualcomm and supported (at different levels - QC 1.0, 2.0, 3.0, and now 4.0) that requires a QC-compatible charger to work at its fastest. Note that while the Pixels' Snapdragon 835 is QC 4.0-compatible (and also compatible with all earlier versions), the Pixels do not support the QC charging profiles, preferring rather the USB-C PD ("Power Delivery") methodology at a max of 9v2A.
2. They will charge it, and at a decent rate, but not as fast as PD-chargers.
3. They will 'normal' charge it, though faster than lower-current chargers. Worth noting that both QC and PD chargers, when paired with compatible phones, charge at varying current and voltage to minimize charge time, particularly when the battery is very low.
4. Answered above.
5. USB-C PD requires USB-C connections on both the charger and handset, as well as a 'proper' USB-C cable. Please be
very careful when buying any 3rd party chargers and cables, as there are a lot of them out there that are not compliant with even the basic USB-C specifications (often lacking a mandatory 56kΩ pull-up resistor), and using them have the potential to cause catastrophic damage to your device. Even generally reliable and well-known "premier" manufacturers are guilty of this failure. There are 2 USB-C PD battery packs available currently - one by Anker, one by RavPower. Both are 'safe,' but the Anker doesn't support the 9v2A profile used by the Pixels. The RavPower is the best bet
I recommend referencing a
spreadsheet created by Benson Leung, a Google engineer, showing his test results on compliance and safety of a number of different accessories (I don't think this has been updated in a while, so there are likely a lot of newer items available that would be good, but the ones marked as safe are still perfectly good choices).
Also, bear in mind that USB-C PD is certainly the fastest way to recharge, but other high current charges will still recharge it at a pretty good rate.
