Introduction

This year’s Google Pixel 9 brings several new upgrades and appealing key features. In terms of the camera, the ultra-wide lens has been upgraded from 12MP to 48MP, and autofocus has been added, significantly enhancing overall photography capabilities. Performance-wise, it is equipped with the Tensor G4 chip and 12GB of RAM for smoother operation.

For the battery and charging aspects, it features a built-in 4700mAh battery and supports 27W PD wired charging. As always, this Google phone does not come with a charger, so we decided to test its compatibility with third-party chargers and power banks.

Charging Compatibility Test

Original Chargers

Although the phone does not come with a charger in the box, Google previously released a 45W charger, which we have on hand. Using it to charge the Google Pixel 9, the ChargerLAB POWER-Z KM003C measured a power output of 8.51V, 2.67A, and 22.75W.

Third-party Chargers

While the phone lacks a charger, it supports the widely used PD fast-charging protocol. Let’s take a look at how third-party chargers paired with the original charging cable perform in terms of compatibility.

First, using a Mcdodo 100W charger, we measured an input power of approximately 9.04V, 2.73A, and 24.69W.

Next, we tested the Sharge 100W charger, which delivered approximately 9.03V, 2.71A, and 24.52W.

Summarizing the compatibility test data with third-party chargers and the original cable, most chargers were able to trigger a 9V voltage. A small number were limited to 5V, while a few incompatible chargers delivered 0W of power.

When visualized as a bar chart, the data showed that over 70% of the tested third-party chargers delivered power levels above 23W, with a maximum of 24.69W. The remaining chargers delivered power between 17-19W. The only incompatible charger was the Huawei 40W model.

Power Banks

Finally, we tested power banks. Using a Samsung 10,000mAh power bank to charge the phone, we measured an input power of approximately 9.05V, 2.72A, and 24.58W.

Next was the MOMAX 10,000mAh power bank, which delivered approximately 8.83V, 2.14A, and 18.88W.

Summarizing the data, the tested third-party power banks charged the Google Pixel 9 at stable power levels, generally triggering a voltage around 9V.

When visualized in a chart, the compatibility of power banks was similar to that of chargers, with most power levels falling into either the 18W or 24W range.

Summary of ChargerLAB

Overall, Google’s 45W charger provided a power output of around 23W, charging the phone to 50% in 28 minutes and fully charging it in approximately 1 hour and 44 minutes. When using third-party chargers, most PD chargers with 30W or higher output delivered power above 24W, with a maximum of 24.69W. Other chargers provided power in the range of 17-19W.
