Ruth's sister

Ruth's sister FL02 international power cord

SKU CH-PPYX-SA9R5

A portable phone cooler with a 4000 rpm hydraulic fan, USB power and three suction cups for devices wider than 56 mm

  • Lightweight portable design at just 6.8 cm x 6.4 cm x 1.7 cm
  • Secure grip with three suction cups for phones wider than 56 mm
  • Quiet 4000 rpm hydraulic-bearing fan runs without disturbing you
  • USB plug-and-play power at 5 V and 0.1 A for instant cooling
  • Fast heat dissipation extends phone battery life during heavy use

Portable Phone Cooler

The FL02 clips onto smartphones wider than 56 mm using three suction cups and draws power from any USB port. Gamers and heavy users get active cooling without carrying a bulky power bank or hunting for a wall socket.

4000 rpm Airflow and Heat Limits

A 4000 rpm hydraulic-bearing fan moves air across the device backplate, lowering surface temperature during extended sessions. The 5 V, 0.1 A draw keeps USB load minimal, but the small 6.8 cm by 6.4 cm footprint cannot dissipate heat from sustained maximum-load scenarios.

USB Power and Physical Constraints

Plug-and-play USB power means the cooler works with chargers, power banks or laptop ports, yet the fixed cable length and suction-cup mount limit positioning on curved or textured backs. Phones narrower than 56 mm cannot be secured, and the 1.7 cm thickness adds noticeable bulk in a pocket.

Questions about this item

Will the FL02 cooler's suction cups hold my phone if it's wider than 56mm?

The cooler supports phones wider than 56mm or 2.20 inches, and its three suction cups are designed to firmly hold and support the device during use.

How can I confirm the 4000rpm fan is running quietly after I plug it in?

The built-in 4000rpm DC motor uses a hydraulic bearing for noise-reducing operation, so you should hear minimal sound when the cooler is powered via USB.

Does the package include a USB power adapter or only the cooler with its attached cable?

The box contains 1 x Phone Cooler with a built-in USB cable for plug-and-play power; a separate USB power adapter is not included and must be sourced separately.
