Lenovo Launches Legion Magnetic Cooler, Magnetic Accessory with RGB Promises to Reduce Up to 20 °C from Phone Temperature in Minutes. See How the Compact Gaming Cooler Works.

Lenovo has just launched a new accessory that promises to change the way users play on their smartphones: the Legion Magnetic Cooler, an active mini refrigerator with RGB lighting that can reduce the temperature of smartphones by up to 20 °C in just a few minutes. Designed for those who demand maximum performance without overheating, the accessory comes with advanced thermal technology, an eye-catching look, and an affordable price – even with features worthy of a premium gaming product.

Targeted especially at long-session gamers and mobile content creators, the cooler is designed to maintain controlled temperatures and prevent performance loss due to overheating, something common in powerful smartphones after a few minutes of intense use.

Smart Cooling Technology with Immediate Effect

The highlight of the Legion Magnetic Cooler is its 10 W semiconductor module, which uses thermoelectric technology to quickly extract heat from the device. According to Lenovo, the accessory is capable of lowering the phone temperature by up to 20 °C under ideal conditions, enough to maintain maximum performance of processors like Snapdragon 8 Gen 2 or Dimensity 8300-Ultra for much longer.

Compact, Lightweight, and Quiet

Even with all this cooling power, the Legion Magnetic Cooler impresses with its size: it measures only 64 x 26 mm and 68 grams, making it extremely portable and easy to use in any situation, even during gaming sessions away from home.

And the best part: all this without excessive noise. Lenovo claims that the maximum noise generated by the accessory is only 30 dB, equivalent to the sound of a quiet library – making it ideal for gamers who record videos, do livestreams, or use headphones.

Usage Modes and Precise Control

The cooler features three operating modes:

Ice Cool: moderate and silent cooling
Extreme Cold: maximum thermal performance
Ice Sealed: balanced mode with adaptive control

These profiles are ideal for different usage moments – from a quick match to gaming marathons or recording 4K videos.

Additionally, it has an integrated digital screen that shows the accessory’s temperature in real-time, along with RGB lighting that changes color according to the heating level – a detail that, in addition to being functional, reinforces the gaming aesthetic appeal.

Connectivity and Thermal Safety

The Legion Magnetic Cooler connects via USB-C with a consumption of 5V and 2A, which means it can be easily used with smartphone chargers or compatible power banks. It also features a waterproof PCB, an important precaution in case of internal condensation caused by temperature variations – ensuring safety even during long sessions and in hot environments.

The magnetic system makes it easy to attach to devices that support this type of fixation (like phones with compatible cases or internal metal structures). On phones without native magnetic support, a adhesive magnetic ring can be used, sold separately.

Not Available in Brazil Yet, but Available via Import

Despite the official launch, the accessory is not yet for sale in Brazilian stores. It was announced in China for just 149 yuan – about R$ 115, and can be purchased via import from platforms like AliExpress or Banggood.

Although there is no forecast for an official launch in the domestic market, consumer interest is expected to hasten the cooler’s arrival through local resellers and marketplaces in the coming months.

For less than 2,000 Brazilian reais, Xiaomi Redmi Note 14 Pro with Snapdragon 7s Gen 3, 12 GB RAM, 120 Hz AMOLED screen, and 200 MP camera challenges top-of-the-line models in 2025

For those who game for long periods, record heavy videos, use applications that demand a lot from the processor, or simply suffer from overheating in the summer, the Legion Magnetic Cooler from Lenovo is a practical, accessible, and efficient solution.

It not only prolongs the device’s lifespan, but also prevents performance drops, enhances the user experience, and adds a stylish RGB look, typical of gaming setups.
