OnePlus has expanded its accessory lineup with the Magnetic Ice Cooling Clip, a new smartphone cooler that the company says is the world’s thinnest magnetic model. The device arrived alongside the OnePlus 15T and targets users who need steadier performance during gaming, video recording, and other demanding tasks.
At a starting price of about $25, the cooling clip tries to solve a common problem on modern phones: heat buildup that can reduce performance and make devices uncomfortable to hold. OnePlus is pitching it as a practical add-on for Android and iPhone users who want a compact cooling solution without carrying a bulky external fan.
A slim cooling accessory built for daily use
The Magnetic Ice Cooling Clip uses a minimalist, compact shape that looks closer to a small power bank than a traditional phone cooler. OnePlus says the thinnest point measures 9.8 mm, while the overall size is 87.6 x 62 x 9.8 mm, with some sections reaching 11.9 mm.
It also weighs about 68 grams, which keeps it light enough for extended use. That matters for mobile gamers and content creators, because heavy accessories can make a phone awkward to grip during long sessions.
Cooling system designed to move heat efficiently
OnePlus uses a more advanced thermal setup than many basic clip-on coolers. Inside the device sits a thermoelectric cooling module, often called TEC, which works alongside a progressive curved air duct design and a centrifugal fan.
This setup pulls in cool air from the top and pushes hot air out through the side. OnePlus says that airflow design helps keep the user’s hand more comfortable while also improving thermal control during sustained workloads.
The company is also aiming for strong cooling without excessive noise. That balance is important because many users want performance relief without the distraction of a loud fan.
Dual-mode cooling for different scenarios
The clip includes dual-mode cooling, which lets users switch between quieter operation and stronger performance. OnePlus appears to be using that feature to make the accessory more flexible depending on the task.
- Quiet mode is aimed at lighter use such as streaming, browsing, or photography.
- Performance mode is designed for gaming, multitasking, and other heavy workloads.
- Quiet mode operates at about 22dB, which is low enough to stay unobtrusive in many settings.
- Performance mode reaches around 36dB, which is louder but still within a level that should remain usable for intense cooling sessions.
That dual approach makes the product more versatile than single-speed coolers that always run at full power. Users can favor lower noise when they do not need maximum cooling, then switch to stronger output when frame stability matters more.
Magnetic mounting supports Android and iPhone
OnePlus says the clip uses a magnetic attachment system with a holding force of up to 10N. That should help the cooler stay firmly attached to the back of a phone during movement, gaming, or handheld shooting.
The magnetic design also gives the device wider compatibility across smartphones, including both Android and iPhone models. For users who switch phones often or share accessories across devices, that cross-platform approach adds practical value.
Bluetooth support is included as well, allowing deeper control through the ColorOS ecosystem. While OnePlus did not position this as a complex smart accessory, the Bluetooth link suggests the company wants more than just a basic fan clipped to the back of a phone.
Power, materials, and hardware details
The Magnetic Ice Cooling Clip uses USB Type-C power input and supports up to 5V/3A. That makes it easy to connect with common charging accessories and modern power sources.
OnePlus built the cooler from a combination of PC and aluminum alloy. The material mix should help with durability while also supporting heat dissipation, which is essential for any device that combines electronics, airflow, and thermal transfer.
An indicator light is also included to show operational status. That small addition makes the accessory easier to monitor at a glance, especially when users are switching between modes or checking whether the cooler is active.
How it fits into the growing phone-cooling market
The launch comes at a time when smartphone cooling accessories are becoming more visible, especially in the gaming segment. Rising chip performance has improved mobile gaming and multitasking, but it has also increased the need for thermal management during prolonged use.
OnePlus is entering a market where competitors already offer strong alternatives. Black Shark has the Ice Cooling Back Clip 6 Pro, which includes a full-color display and up to 35W of cooling power. Red Magic also makes the Cooler 8 Air, a lighter 65-gram unit that promises cooling down to minus 20 degrees Celsius and adds RGB lighting.
That competition shows how accessory brands are treating phone cooling as a real category rather than a niche add-on. In that context, OnePlus is trying to stand out with slimness, magnetic mounting, and a design that feels easier to live with than more aggressive gaming-style hardware.
Why this accessory matters for heavy phone users
The Magnetic Ice Cooling Clip speaks directly to users who push their phones hard. Mobile gamers often see performance drops when heat builds up, while creators shooting long video clips or using demanding apps can also run into thermal limits.
Heat does not just affect comfort. It can also trigger throttling, which reduces speed to protect the hardware and can result in lower frame rates, slower app behavior, or shorter sustained performance. A clip like this is meant to reduce that pressure and help the phone stay consistent for longer periods.
For users who care about ergonomics, the lightweight build is part of the appeal. A 68-gram cooler is easier to accept than a heavier accessory, especially for handheld gaming sessions where every extra gram matters.
