Black Shark Phone Cooler for Gaming FunCooler 4, Wired Mobile Phone Cooling Fan Lightweight Quiet with RGB Light, Cellphone Radiator for 2.67-3.45 inches iPhone/Android, Retaining Bolt

One thing I’d like to point out is you HAVE to have this thing connected to the charger and the adapter has to be at least 3.1A but on their website and app they recommend 5V 2A for their coolers. So if you get a red light and the fan doesn’t blow that’s why. FOR THE VALUE this is a great device for cooling my iPhone 12 Pro. This is my first cooler and im AMAZED by the quality! Its fits the phone nice. The noise is not obnoxious at all but if you’re streaming I suggest you move the mic away from your phone because it still picks up the blowing sound. I’ve played 4 - 6 matches of pubg mobile and I haven’t received any frame drops or lag and I can play at even higher settings than before. If one thing I could change is how it has to stay plugged in to work but it’s not that bad. I also would advise black shark to put packaging in English for NA customers. The Chinese letters were a bit misleading but they left QR codes the their app and I put them in the video i provided so that yall can see. I would give this device a 9/10. Definitely going to upgrade to the pro version soon. Had to mute the video because my baby nephew in the background yapping baby talk.

Buen producto, cumple con su funcionamiento, si es tu primer cooler que vas a comprar, es bueno para enfriar el celular, en mi caso lo uso en la prepa para mantenerlo fresco durante el día ya que dentro del salón los celulares tienden a calentarse mas rápido, cuando lo utilizo para investigar temas es bueno manteniendo la temperatura baja, cuando lo utilizo para jugar en horas libre durante la prepa se mantiene a una temperatura estable, pero cuando lo utilizo en casa se mantiene a una temperatura fresca, ya que en casa es otro ambiente y es donde veo mejores resultados. He sentido que con el cooler la batería de mi cel tiende a durar más durante las horas de juego, este producto es bueno para empezar en este tema de los colores

I use this as a phone mount for my car. I drive something with a convertible rooftop, and it's frequently down in the summer, which means my phone is not only under the windshield and not getting airflow but is also getting blasted by blazing sunlight. I have been using this for a while, and it works excellently. The gripping arms are more sturdy than other options I have tried, and this does an excellent job moving heat so long as the fan isn't blocked. Even then, it still does well enough. The fan is a bit loud, but when driving I don't hear it and protects my phone from overheating while running my Android Auto. Absolutely recommend and I plan on getting another. Just note, this won't work well with 99% of cases! It works best if you don't have one at all, but I was able to find one for my phone made of a thermally conductive material. Quick additional note: Make sure you use a strong enough USB power adapter! Even some of my 15w USB-C bricks don't like this thing and it won't power it. The technology these things use is VERY power hungry and not just any USB adapter will work, if it doesn't power on- try something else!

Decepcionante, dejo de funcionar a los 3 meses con normalidad, ahora es un pisa papeles, inente contactar con soporte y no me contestaron de ahi en fuera cuando funcionaba lo hacia bien
