Introduction

The recently launched iPhone 15 series by Apple may mark one of the biggest turning points in iPhone history. It features a switch to a USB-C physical port for charging, significantly improving connectivity compatibility. Additionally, it boasts a battery capacity of 4852mAh and comes with a braided USB-C to USB-C charging cable.

We received the all-new iPhone 15 Pro Max just yesterday, so without further ado, let's dive into ChargerLAB Compatibility 100 test.

Charging Compatibility Test

Next, ChargerLAB will conduct a comprehensive test on the compatibility of the iPhone 15 Pro Max, evaluating its performance with a selection of more than 100 charging devices. These devices include Apple chargers, third-party chargers, power banks, and portable power stations, aiming to cover the majority of users' charging scenarios.

It's worth noting that even though we conducted this test using the included braided USB-C cable, the USB-C port on the iPhone 15 Pro Max is compatible with mainstream third-party USB-C charging cables.

Apple Chargers

First, let's take the Apple 29W charger (model: A1540) as an example. ChargerLAB POWER-Z KM003C shows that it can deliver 14.5V 1.75A, equivalent to 25.43W of power to the iPhone 15 Pro Max.

We tested all the Apple fast chargers we have, we can see that only the 29W one reaches a power of more than 25W with relatively high voltage and low current, while the others are at the 9V3A level.

Plotting the data into a bar graph, it's surprising to see that the 29W charger, with its unique fast-charging strategy, outperforms chargers with much higher power. It takes the top spot, although the advantage is minimal. Even the lowest-powered 20W charger reaches its own limit. Overall, the power output hovers around 25W, very stable.

Third-Party Chargers

Moving on to third-party chargers, let's take the AOHi 140W charger (model: AOC-C012) as an example. It can deliver 8.98V 2.98A, equivalent to 26.72W of power to the iPhone 15 Pro Max.

Summing up the test data, it's a bit repetitive as all the chargers, without exception, output at the 9V3A level.

Plotting the data into a bar graph, we can see that the charging power of the iPhone 15 Pro Max mainly falls into two categories: 18W and 27W. The former is limited by the charger's performance, while the latter is restricted by the phone's own charging capabilities. However, the HONOR 65W charger is an exception, consistently delivering only 17W, ranking at the bottom.

Power Banks

Next up, let's talk about power banks. Except for the IDMIX Magnetic 10000mAh, all the tested devices trigger the 9V voltage level.

Once again, plotting the data into a bar graph, the power output remains around 25W. So, power banks that support the PD 9V/3A voltage level can meet the iPhone 15 Pro Max's charging needs.

Power Stations

Lastly, we have power stations. These devices generally have 60W/100W USB output ports. As expected, all the devices tested triggered the 9V voltage level, with no 5V voltage level detected.

Plotting the data into a bar graph, the iPhone 15 Pro Max's charging power remains around 25W, showing no significant variation when compared to various chargers, power banks, and other devices.

Summary of ChargerLAB

In summary, whether paired with Apple's own charger or third-party chargers with a rating of 30W or higher, the charging power of the iPhone 15 Pro Max consistently reaches its maximum charging capacity, which is around 25W. In terms of charging compatibility, it can undoubtedly be considered at the top tier. However, it's unfortunate that in today's smartphone landscape where many Android phones can reach charging speeds of 45W, 100W, or even 200W, this maximum power output may seem somewhat inadequate.

We hope that in the next generation, they will address this historical weakness and provide users with the charging experience they should expect in this price range for Apple smartphones. In conclusion, the iPhone 15 Pro Max successfully passed the ChargerLAB Compatibility 100 Test. Below is the compatibility 100 test report issued by us.
