CRJ Full Speed 12V Voltage Step-Up USB to 3-Pin and 4-Pin PC Fan Sleeved Power Adapter Cable

I use it to test various 12v pc fans. Also used it to prime a pump on a liquid cooling computer and bleed the air out of the system.

Ive pugged this into several different charging blocks. Works great, awesome for testing fan motors. I bought it to use in a soldering vent setup, keep using it to test computer fans.

Works well, would be better if it had a dial to adjust speed for PWM fans. The usb plug is large and sticks out when I connect this to my dongle, but overall it works as intended.

First of all, it is important to know not to aim a fan so it is blowing at the exhaust of the PS5, if youre setting up a fan behind your PS5, have it blow the air away from the PS5. Youll probably want to set up your PS5 settings so it only supplies power to the USB port while the PS5 is on, that way the fan isnt running 24/7 while your PS5 is turned off.

Bought one and it worked well so bought more. All cables are working fine.

Ordered a 5v cord first time.. This works great for the higher RPM computer fans-- in ANY type of build. ANYTHING you could need one for.

When it works it works great, it steps the voltage up to properly use a 12V .25A static pressure fan and I appreciate that. Unfortunately its making extremely bad contact and only works with someting putting pressure on the leads. Annoying.

Purchased CRJ Full Speed 12V Voltage Step-Up USB to 3-Pin and 4-Pin PC Fan Sleeved Power Adapter Cable for testing and powering 12V fans. Adapter is made of high-quality materials and is easy to use. Works perfectly for testing 12V, 2 to 4 pin fans. Highly recommended!!!

My son bought this to use with his custom 3d-printed laptop cooler/stand (designed/built/printed himself). He ran two 120mm fans off of it and it worked great. No issues with the USB port or the fans when using the cable.

Working pretty good with my 200x200 cooling fan (12V, 0.42A)
