Belkin BOOSTUp 10w Pixel 3 Wireless Charger
This article explains part of the situation. Basically, Google isn't letting fast chargers deliver the faster-charging speeds to the Pixel 3 and Pixel 3 XL. Not unless it's a "Made for Google" product certified by Google.
If that's what you want, the Belkin BoostUp 10w official Pixel 3 and Pixel 3 XL fast wireless charging pad is what you want. Belkin is one of the most popular accessory manufacturers, and they're part of the Made for Google program.
This charger is cheaper than the Pixel Stand, coming in at $59, but it's still more expensive than most other 3rd party chargers all over Amazon or at Best Buy stores. Again, we think there's a small chance Google will reverse course, but if not, this is one of the best wireless charging pads for the Pixel 3.
Belkin's BoostUp delivers the full 10w, comes with a 5ft charging cable and wall plug ensuring the proper power delivery, has an LED for charging, and an LED that will let you know if something's on the charging surface when it should be. It's a nice option for those interested.
