Understanding the 45W Charging Constraint

On the surface, the Pixel 11 Pro XL stands out as the fastest-charging device in Google's history, boasting support for up to 45W via wired connections. The manufacturer suggests that users can achieve a 75% charge in just 30 minutes, provided they use a compatible USB-C PPS (Programmable Power Supply) charger. However, reality proves to be more complex than simply utilizing any high-wattage power brick.


The Importance of Voltage Profiles

Recent testing reveals that the smartphone is remarkably selective regarding its power source. To reach maximum charging potential, the device specifically requires a charger capable of delivering 21V over the USB Power Delivery PPS protocol.

Observations indicate a stark performance gap depending on the hardware used:

  • When paired with Google's proprietary 67W charger, the phone successfully reaches peak speeds exceeding 40W.
  • In contrast, third-party 67W PPS chargers that lack the specific 21V output profile often struggle to exceed 25W.

The Challenge for Consumers

Since Google no longer includes a power adapter in the box, users must navigate a complicated landscape of charging accessories. Owning a generic 45W or 65W charger does not guarantee that the device will charge at its maximum rated speed. Consumers intending to utilize existing equipment must verify that their hardware supports the exact voltage configuration the Pixel 11 Pro XL demands.


Is the Upgrade Worth the Effort?

The speed improvements over the previous generation are notable but relatively modest. During rigorous testing, the Pixel 11 Pro XL reached a 50% charge in 21 minutes and a full charge in roughly 70 minutes. Compared to the Pixel 10 Pro XL—which achieves a full charge in approximately 80 minutes—the advancement is present but may not justify the significant effort or additional financial investment required to source the precise, high-voltage compatible charger.


Ultimately, if top-tier charging speeds are not a priority, standard USB-C chargers remain functional. However, those strictly seeking the fastest possible replenishment for their device must ensure their power adapter is fully compliant with the 21V requirement.
