S9 Magnetic Suction Radiator Phone Cooler for Gamers

The S9 Magnetic Suction Radiator is a compact external cooling accessory designed for smartphones, especially suited for gaming, streaming, or heavy usage scenarios where device temperatures tend to rise. Its primary purpose is to help the phone maintain optimal temperatures by attaching to its back and providing active cooling (via semiconductor/thermoelectric cooling + airflow) and improved heat dissipation. Because phones under load (gaming, video, high brightness, 5G, etc) can get hot, this accessory aims to enhance performance stability, reduce thermal throttling, and help battery longevity.

Here is a more detailed breakdown of its design, build, functionality and practical usage:

• Design & Build

The unit uses a strong magnetic suction mechanism so it can attach to the back of a metal-frame or compatible phone (or to a phone with a metal plate) without the need for clamps or complex setups.

Materials used include ABS plastic housing + aluminium heat-dissipation plate + magnet module. For example one spec lists: “Material: ABS + Aluminum + magnet + ice porcelain” for a variant.

Size: One listing gives ≈ 68 mm × 26 mm (Φ 68 × 26 mm) with net weight ~65.8 g.

Colour/finish: Some variants show anodised aluminium dual-panel black/purple, or black/white.

Additional design elements: Some models have RGB/ambient lighting for aesthetic effect.

• Cooling & Performance

Core cooling mechanism: many listings refer to a semiconductor refrigeration chip (thermo-electric cooler, Peltier) built into the unit. This allows the cooler to actively draw heat away from the phone’s surface.

Fan or air-duct + heat-dissipation plate: some variants include ultra-quiet fan(s) or passive airflow channels to enhance heat removal. Example: “vortex silent air duct design” referenced.

Two cooling modes: A product listing mentions two modes via side button: “Normal refrigeration mode” and “Enhanced cooling mode”.

The magnetic attachment means the cooler can be applied to the phone without physically holding it, making it convenient for gaming sessions, or even for streaming/recording.

Practical advantage: By keeping phone temperature lower, it may avoid overheating-induced performance drops (throttling), reduce discomfort when holding the phone, and potentially improve battery longevity under stress.

• Usage & Compatibility

Compatible with iOS and Android smartphones (with a suitable flat back surface or metal plate) as many listings say “for IOS Android gaming accessories cool heat sink”.

Best for heavy-use scenarios: mobile gaming, live streaming, extended usage, high brightness + 5G, etc.

One note/warning: Because the semiconductor cooler can reduce surface temperature significantly, some listings caution of condensation forming (“During the cooling process … condensation water may occur … the occurrence of water droplets or icing is a normal physical phenomenon”).

Power supply: One spec indicates 5 V/2 A max supply.

Because of its magnetic attachment, it is relatively portable and easy to remove or carry.

• Considerations

The actual benefit will depend on how well the phone’s thermal interface is made and how the cooler is attached (good contact surface needed).

May add thickness or weight to the back of the phone; the magnet attachment strength and phone case compatibility should be considered.

If the cooler draws significant power, that may add to battery drain or reduce usable battery life if powering from the phone (if it needs cable) or from external power.

The cooling benefit may be limited if the phone’s internal heat source is from the CPU/GPU far from the surface—external cooling can only go so far.

Correct usage and setup are key (e.g., clean surface, ensure good contact, avoid blocking ports).
