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

Needed this to power a 2pin fan and i had no issues, quality cable!

Does what its advertised to do, tested on PS3. Was purchased to power up a 140mm PWM fan that is going to move air towards exposed SSD heatsink on PS5. Fan started without any issues when used PS3 USB ports, so far so good. No build quality issues observed on delivery. Will later test if it works with laptop ports. Also performed well in combo with a fan speed controller attached in chain towards the fan. Product recommended.

Works perfect, no complaints here

I got this product to use an extra 140mm pc fan on top of my Xbox Series X. This adapter provides 12v and the fan runs at full speed which is ideal for me. The Xbox is much cooler to the touch and I feel better than the internal parts are cooler too. I used an extra USB wall adapter which provides 2 amps at 5/12v.

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.

I use a portable usb battery and one of my old computer fans with this cable to cool the inside my costume helmet. It works great.

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.

Using with 12v fan to silent a very noisy network switch. Works great and has been working great for over a month now, no issues and good build quality.

Works as designed (regulates all input voltages to 12V). however did not meet my need as i hoped it would be proportional to input voltage. My mistake not mfrg.

Tested out a few fans and a pump with this cable.
