The Wasserstein On-the-Go USB-C charger is a compact way to charge a Pixel Watch 4 or 5 using a USB-C cable you already carry. 9to5Google reported on October 6, 2026, that it was $19.99 on Amazon for Prime members; check the listing for the current price and availability, since that dated deal may have changed.
What the Wasserstein charger does
Rather than bringing a dedicated charging cable, you attach this small dock to a separate USB-C cable. Google Store lists the charger’s body at 1.28 × 0.63 × 0.64 inches and 0.28 ounces. The package includes the charger and a manual, but not the USB-C cable or power adapter.

What the reported sale means

Its September 29 report had cited a $25 sale price; the later report is the newer figure, not a guarantee that either price remains live.

How it compares with Google’s official dock
Google’s Quick Charge Dock is a cable-based alternative for Pixel Watch 4 and 5 in both sizes. Google says, “Take your Google Pixel Watch 5 or Pixel Watch 4 from zero to 80% in 30 minutes.” That is Google’s product-page claim, not an independent comparative test. Google specifies a USB-C-compatible power adapter rated at least 7.5 W, sold separately. Google Store’s Quick Charge Dock listing

Which one makes more sense for travel?
- Choose the Wasserstein dongle if minimizing the charger you pack matters and you already carry a compatible USB-C cable and the required adapter. Its compact dimensions and low listed weight are the main travel advantages.
- Consider Google’s dock if you prefer its dedicated dock format or want the charging-speed claim Google publishes. You will still need to bring a separate adapter meeting Google’s stated minimum.
