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

couldnt use did not receive working item

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!!!

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

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.

This is exactly what I wanted and exactly what I expected. Im using this to power a case fan that I no longer need and use for other purposes.

I greatly underestimated how fast or loud powering a 120mm case fan with this would be. The cable itself isn’t anything special and feels sturdy enough. Most importantly it does what it is supposed to do. So if you need high rpm, high noise, 24/7 fan operation you cant go wrong.

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.

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.

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

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.
