The best charging accessories for the Google Pixel 2 XL

By Team Ventev Topic: Tech Specs

The Google Pixel 2 XL has been released to solid reviews. Wired refers to it as “….the Android phone to buy.” Engadget gave it a score of 91, the best in its category.

The strongest selling point is the excellent camera, which has the highest rating from benchmarking firm DxOMark. But the Pixel 2 XL also easily integrates into the Google ecosystem, and it skips the undeletable bloatware that mars the user experience on other phones.

That said, there have been quite a few complaints about the Pixel 2 XL’s charging speed. While the phone can charge from zero to 25 percent in about 25 minutes, it takes nearly two hours to go the rest of the way to 100 percent. For perspective, that’s actually not that bad. The iPhone 8 has a smaller battery, but it also took about two hours to fully charge.

The complaints about the charge times stem from the Pixel 2 XL’s use of USB Power Delivery™ to charge. Using Power Delivery, which can provide up to 18 watts of power, may actually be slower than using a 15-watt charger.

While Power Delivery can handle high wattage, the Google Pixel 2 XL doesn’t request higher wattage. If the device is charging from a USB Power Delivery charger with a 9V profile, it will select this 9V profile and charge at 9V until full. If the device is plugged into a 5V, 3A charger it obviously only has the 5V profile to choose from.

In our testing, it looked like the phone wasn’t requesting more power (greater than 15 watts) from the higher power chargers, which means while charging at 5V there is less conversion that needs to happen to go into the battery, causing a faster charge.

You’ll notice that the USB Power Delivery chargers are about 10 minutes behind the others when charging to 30 and 50 percent. There is no an advantage to charging with the more powerful 9V profile that our USB Power Delivery chargers offer because the device does not request enough power from the charger. The wallport r1300 charges at a slightly faster speed due to a more efficient energy conversion of the 3A, 5V profile.

When you charge your phone, it’s a lot like filling a glass of water. With a mostly empty glass, you tend to pour heavily, backing off and pouring more slowly as the glass approaches full. When a battery is close to zero, it accepts more current. When the battery approaches full, it charges at a trickle.

So, what’s the best spare charger for the Google Pixel 2 XL? As you can see from the chart, any of the Ventev products above have nearly identical total charging times.

The Ventev wallport r1300 and the Ventev dashport r2400c both offer improved charging times over the Pixel 2 XL’s in box charger during the beginning of the cycle. If you’re the type of person whose battery is seemingly always close to zero, either charger is the perfect option to have on hand.

The wallport r1300 is a 15-watt wall charger that comes with folding prongs to make it compact.  The dashport r2400c comes with a hardwired USB Type-C™ cable, plus an extra USB Type-A port to charge an extra device.

The Pixel 2 XL is a great phone with a stellar camera. But, some chargers are clearly faster than others when it comes down to it. Your time is valuable, so choose wisely.
