Google Pixel Flex 67W USB-C Fast Charger review: Protocol perfection with one pretty huge oversight

Google Pixel Flex Dual Port 67W USB-C Fast Charger Google's 67W dual-port charger supports the latest and greatest USB Power Delivery standards and impressive split-power capabilities that'll effortlessly fast-charge your new Pixel and much more. However, Pixel-priority charging causes headaches when mixing and matching gadgets.

Along with the new Pixel 10, I’m lucky enough to have the latest Google Pixel Flex Dual Port 67W USB-C Fast Charger in hand (technically the UK version, but the US unit has the same specs). This word salad of a charging accessory is the brand’s most powerful plug to date, and with two ports onboard, it’s set up to do much more than charge your new phone. But is it the best wall charger that you can buy?

Let’s get right into the good bits. The Pixel Flex Dual Port charger (let’s just call it that from here for the sake of brevity) works with the key protocols used by most US-bound flagship smartphones, meaning it can charge your Pixel, iPhone, and Galaxy as quickly as possible and will power other models reasonably rapidly as well.

It supports USB Power Delivery on both ports for phones, tablets, and laptops (up to 20V/3A), plus PPS at up to 21V for variable charging on devices like the Pixel 10 Pro XL. Robust protocol support greatly simplifies the effort involved in picking the right charger, so big point for Google here.

If your gadgets support USB Power Delivery, Google's 67W plug can power it.

If you want the specs, it’ll do USB Power Delivery with at least 3A at 5V, 9V, 15V, and 20V on either port. Variable power via USB PD PPS is supported at 5V-16V at 4A or up to 21V at 3.35A, which covers you for every phone on the market today.

Unfortunately, there’s no UFCS, which might reduce compatibility with some newer handsets from China, but flagship models tend to support PPS these days anyway. There’s also no support for Quick Charge 3.0, Samsung Adaptive Fast Charge, or China’s countless older proprietary standards, which is worth considering if you’re planning to charge a more eclectic set of older gadgets. Basically, Google demands we get with the USB Power Delivery program, which is fair enough for modern phones, but breaks fast-charging compatibility with much older gadgets. However, this likely won’t be an issue for most consumers.

Pixel phones get a priority pass

The next important question is how the charger handles two devices simultaneously. Google claims the plug prioritizes Pixels, and my testing suggests this is true, but with certain caveats.
