Ps4 controller disconnecting

So i’de like to start with that i brought the keymander 2 today and to keep things polite I’ve had nothing but issues I’ve followed the guide for ps4 step by step with no luck, the keymander disconnects my controller every 5 seconds it doesn’t even leave me long enough to click a button in the menu, i’m using the micro usb cable provided, i have the power cable plugged into a phone charger plug, i’ve also tried plugging it into my pc both didn’t work I’ve tried plugging the cable pre attached into both usb port on the front of the standard ps4, I’ve updated the software on the app, ive tried multiple cable for power still no luck I’ve searched everywhere online and found no solution but seen multiple users with the issue, the only other problem i could imagine is im using a v2 controller with an old ps4 other then that ive followed all steps and tried multiple resolutions no luck if someone could guide me to a fix would be much appreciated as i havent had the chance to use it yey
