Introduction

Recently, OnePlus launched its first compact-size smartphone in the Chinese market—the OnePlus 13T. It features the Snapdragon 8 Elite mobile platform and boasts the largest VC cooling area among small-screen phones, combining high performance with exceptional heat dissipation. Notably, it houses a massive 6260mAh battery. So how does it perform in terms of charging compatibility? Let’s find out.

Charging Compatibility Test

Original Chargers

Let’s first examine the charging compatibility of the OnePlus 13T with OPPO's range of original chargers. To ensure accurate results, all tests were conducted using official OnePlus or OPPO USB-C cables.

Using the OPPO 100W USB-A charger, the ChargerLAB POWER-Z KM003C tester recorded a charging power of 9.40V at 7.35A, totaling 69.16W.

A series of tests were conducted using OPPO chargers of various power ratings, all paired with original charging cables. The highest recorded power reached around 69.06W. All OPPO chargers, except for the 65W model, were able to deliver a full 7A current.

Based on the resulting bar chart, the OnePlus 13T achieved a consistent power range of 58–70W with original OPPO/OnePlus chargers, showing strong compatibility with its native charging ecosystem.

Third-party Chargers

Next, let’s take a look at the OnePlus 13T’s compatibility with third-party chargers. Several models were selected for this test, and the results are as follows.

For example, the Huawei 100W charger delivered 8.68V at 3.94A, achieving a power output of 34.21W.

Summarizing the data, most third-party chargers triggered a 9V output voltage, with peak current reaching up to 3.94A.

From the bar chart, it’s clear that charging power was mostly concentrated in the 17W and 25W ranges. Interestingly, since both the Huawei 100W charger and the OnePlus 13T support the UFCS fast charging protocol, they were able to negotiate a higher current, reaching 34.21W—resulting in a better charging experience.

Power Banks

Using the EGIOZR 10000mAh 45W power bank to charge the OnePlus 13T, the recorded power was 9.05V at 3.63A, totaling 32.88W.

Most third-party power banks triggered a 9V output, with current levels ranging from 1.9A to 3.7A—very similar to the behavior observed with third-party chargers.

According to the bar chart, power delivery was mostly concentrated at 18W and 25W. For power banks that support the UFCS fast charging protocol, power output reached around 34W.

Summary of ChargerLAB

The OnePlus 13T demonstrated excellent compatibility with its original chargers, achieving peak charging power of around 69.06W—greatly reducing charging time and fulfilling user expectations for high-efficiency charging.

As for third-party chargers, while most outputs fell within the 17W and 25W ranges, the phone’s support for the UFCS fast charging protocol allows it to reach around 34W when used with compatible chargers—delivering an improved experience. Power banks showed similar trends, with most operating at 18W or 25W, and select UFCS-compatible models reaching around 34W.

In conclusion, the OnePlus 13T shows a dual advantage in charging compatibility: high-speed charging with original equipment and solid performance with third-party devices. For the fastest charging, we recommend using the original charger. For broader charging options, third-party chargers or power banks that support the UFCS protocol are excellent alternatives.
