Introduction

A few days ago, ChargerLAB presented a compatibility 100 test video for the 16-inch MacBook Pro (2021) after upgrading it to macOS 13.5. Now, we will provide a detailed textual description, including more data, to give everyone a clearer understanding of the charging compatibility of this laptop.

For those unfamiliar with this laptop model, allow us to provide a brief overview. The 16-inch MacBook Pro (2021) is equipped with a 140W MagSafe charging port that supports the PD3.1 fast charging protocol. When combined with the authentic MagSafe charging cable, users can enjoy an optimal charging experience. Additionally, the side USB-C port also supports charging, albeit at a slightly lower power compared to the MagSafe cable. In this article, we delve into the compatibility of this laptop after an upgrade, with all tests conducted using the MagSafe charging cable.

Original Chargers

Let's begin by examining the performance of the original chargers. Summarized in the table, the test data reveals that with the exception of low-power chargers, all other chargers trigger a 20V PDO, while Apple's 140W charger impressively triggers a high voltage of 28V.

When we visualize the data in a bar graph, the Apple 140W charger emerges as the top performer, delivering a remarkable 132.72W, perfectly triggering the PD3.1 fast charging protocol. When utilized with the MagSafe charging cable, all tested chargers can fully reach their power limits, demonstrating exceptional performance. However, for optimal results, chargers with a capacity of 60W or higher are recommended to attain the best charging experience.

Third-Party Chargers

Turning our attention to third-party chargers. Most of these chargers activate a 20V PDO, while the 140W charger triggers a 27V PDO.

Represented in a bar graph, chargers of varying power levels offer discernible charging tiers for the laptop. This indicates a strong level of compatibility. The MagSafe charging cable extracts the full potential of each charger; among the 69 third-party chargers tested, none exhibited incompatibility or inadequate charging power. The charging compatibility demonstrated is truly impressive.

Power Banks

Next, we evaluate the performance of power banks. As we analyze the test data, we find that power banks supporting the PD3.1 protocol consistently trigger a high voltage of 27V.

When visualized in a bar graph, three power banks stand out for achieving charging powers exceeding 133W. Remarkably, all ten tested power banks showed compatibility without any signs of incompatibility or underperformance. The power banks, whether high-capacity or low-capacity, uniformly achieve their maximum power limits.

Power Stations

Finally, we assess the capabilities of portable power stations. Among the ten stations tested, all reliably triggered a 20V PDO with a current of 4.66A.

Visualizing this data in a bar graph reveals a slight variance in the charging power of the ten portable power stations, all surpassing 90W, and without any instances of incompatibility.
