USB-C Power Delivery and Qualcomm QuickCharge are mutually incompatible. This battery pack doesn't support USB-C PD, just the ordinary USB-C power that's only slightly souped up over conventional USB (15W vs 12W). There are very few battery packs that support USB-C PD today. Anker's boat anchor and Mophie's XXL, and a couple other less distinguished ones, and they are all well above $100, This pack is not even remotely in the same category. The only USB-C benefit (hopefully) is that it will recharge faster than over micro-USB, on a 26,800 man pack that can mean hours shaved off. Hopefully as new USB-C PD chipsets for battery packs become available, we will have more options and lower prices, but in any case I would not purchase a USB-C charger, battery pack or cable that hasn't been tested by Benson Leung of Google.

fazalmajidNot sure which Anker you are referencing but they have a 20,100 that claims PD support and is only half a brick and Aukey has a 10k they claim supports PD that looks pretty svelte.

OSUgrad1992The 26800 mAh. The 20000 PD looks like it is fairly new, and yes, the weight savings are welcome. I don’t see any Aukey 10000mAh PD. The PB-Y16 is an ordinary 15W, not the 30W or more of PD.

OSUgrad1992Hmmm. Another Chinese "brand" straight out of a random number generator. Given how many USB-C products are defective or even outright dangerous, I would not take a risk until it has been tested and blessed by Benson Leung or one of his merry band of Google USB-C vigilantes. Even Apple took three tries before they got something as simple as a 2m USB-C charge-only cable right, and Anker had serious issues with its 1st Gen USB-C products as well.

fazalmajidSo are you saying that for USB-C based devices (like my Pixel 2 XL) I'll see no performance gain between this and and a "generic" power bank with some form for fast/QC?

RochambeauxYes (if I can jump in without being rude!)... You want USB-C Power Delivery to obtain true "charging rapidly" status in a Pixel 2 (or Pixel 2 XL). You'd also want to ascertain that the output levels within the implemented USB-C PD model match the optimum level for these phones, otherwise you may still see "charging rapidly", but find your phone charging more slowly than with the OEM charger. USB-C Power Delivery compatible devices use specific charging profiles, e.g., at 9V, the device might draw 2A (total of 18W), while at 5V, the device might draw 3A (total of 15W) -- either of could qualify as USB-C PD, but if the device actually draws 18W it could potentially charge faster than a charger delivering 15W.
Personally - I ordered a couple of extra OEM chargers (from BestBuy) to use around the house, as well as some nice ones from Anker (they were on sale at Amazon a few weeks ago) -- these all work well. I've got a RAVPower "Turbo" RP-PB043 battery that holds 20100 mAh -- I think this model is still available online. This one supports QC 3.0 output, as well as Type-C Output: although the online material doesn't explicitly state "USB-C Power Delivery", the battery puts out 5V / 3A (15W) over USB-C, and triggers the Pixel 2 XL to state "Charging Rapidly" -- and indeed, the phone charges quite quickly, does not become hot, and all seems to work quite well. Additionally, you can charge that battery using QC 3.0 input -- AND I've tested and found that, like proper USB-C power connections, I can charge the battery quite rapidly by plugging one of my USB-C chargers into the USB-C port on the battery -- so it is, in fact, bi-directional. It seems that the RAVPower battery is, indeed, quite compatible with both QC 3.0 and USB-C Power Delivery.
That said -- this new battery is appealing -- but I'd like to know if it will actually support both QC 3.0 and USB-C Power Delivery, and at what V/A/W output profiles. If that info isn't available, the appeal is greatly limited for any of us using devices that rely on USB-C Power Delivery.
