Magnetic Phone Radiator Cooler with 300mAh Battery and USB Power

This magnetic phone radiator cooler is a compact accessory designed to help manage heat during mobile gaming, video streaming, or other intensive phone tasks. It combines a built-in cooling fan with a magnetic mounting system, allowing it to attach to the back of a compatible phone. The device is powered by a 300mAh battery and can run for approximately 2.8 to 3 hours on a single charge, depending on usage conditions. With a bare metal size of 6.9 x 5 x 2 cm and a weight of just 27.5 g, it adds minimal bulk. The cooler is made from ABS and PC materials and is available in Black or Silver. It charges via a DC 5V USB input at 1A-2A using the included 1-metre Micro interface power cord. Four magnetic guide sheets are supplied to help with secure placement.

Features and Construction

The cooler is built around a magnetic attachment method and a built-in rechargeable battery, making it a portable option for phone cooling. Its construction uses common thermoplastics and a compact fan assembly.

Material and Build

The main material is a combination of ABS and PC, which provides a lightweight yet rigid housing. The bare metal unit measures 6.9 x 5 x 2 cm and weighs 27.5 g, so it does not add significant weight to a phone. The plastic casing houses the fan and battery, while the magnetic guide sheets are used to create a magnetic surface on the phone if needed. The included 1-metre Micro interface power cord allows charging from a USB port.

Size and Practical Fit

With a footprint of 6.9 cm by 5 cm and a thickness of 2 cm, the cooler is designed to sit on the back of a phone without covering the screen. The magnetic attachment is intended for phones that either have a built-in magnetic ring or can use one of the supplied guide sheets. The low weight of 27.5 g means it is unlikely to make the phone feel top-heavy during handheld use. The packaging size is 13.5 x 9.5 x 4.2 cm, and the total weight with packaging is 76.5 g.

Uses and Placement

This cooler is intended for situations where a phone may generate heat, such as gaming or streaming. It can be attached to the back of a compatible phone and powered on to provide active cooling.

Event or Professional Use

For mobile gamers, the cooler can help maintain lower phone temperatures during long play sessions. It may also be useful for live streamers or anyone using their phone for extended video recording or video calls. The 2.8-3 hour battery life supports typical gaming sessions, and the USB charging means it can be recharged from a power bank or wall adapter.

Everyday Home Use

At home, the cooler can be used while watching videos, browsing, or playing games. The magnetic attachment makes it easy to put on and take off, and the compact size means it can be stored in a drawer or bag. The two colour options, Black and Silver, allow it to blend with different phone designs.

Benefits and Buying Value

The main benefit is active cooling in a portable form, with a rechargeable battery and simple USB charging. The use of magnetic guide sheets adds flexibility for phones without built-in magnets.

Reuse and Low Maintenance

The cooler is reusable and does not require disposable parts. Maintenance is limited to wiping the surfaces with a dry cloth and recharging the battery as needed. The absence of complex care routines makes it straightforward to keep in working order.
