Radar Detector Cable, USB to RJ11 Plug Cable,for Escort Radenso XP Uniden Beltronics Cobra Whistler Radar Detector,Replacement Power Cable for Radar Detectors (RJ11-3.3ft)

I'm one week in and the cord is working perfectly. Only "issue" is using the USB port on my truck my radar detector stays on even when the car is shut off so I just unplug every time I get out of the vehicle.

Good product and fast delivery

At least for a Valentine1 on GM vehicles, this will deliver just enough watts to light up and make you think it’s working, but DOES NOT actually detect radar and alarm. Hopefully this will help other shoppers since there was no information when I was shopping. Keep reading if you’re curious why not. The cable does convert normal 5v USB to 12v RJ11, but Valentine1 radar detectors need 2.8watts minimum standby power, and up to 5.2watts max. At least for GM vehicles, USB output is only 500 mA (standard minimum for USB). That’s 2.5watts total power output. In case you’re wondering, this is also why GM ports will not charge a tablet, only your phone. Worse, it is just enough power to get the detector to light up, but it is incapable of actually detecting or alarming. A trip past the police station confirmed that, so I paid to have it patched into the fuse panel and wired up to pop out of the headliner just to the right of my rear view mirror. Now it alarms with 5+ guns detected at the station. Anyhow, it’s both an issue with GM and the cable, since the mfr advertises this for radar detectors and you’d only need one if your new vehicle ditched the 12v socket. So, I give it one star for misleading advertising. That said, if GM put out 2.4amps on USB (say, enough to charge an iPad), it’d probably work perfectly. If this cable were USB-C, that port might have more amps too. One alternative is to use an iPad power brick in the AC Inverter plug and run the wire from there. For me, it doesn’t reach, takes up too much space, and I just wanted a cleaner install and was willing to pay. Regardless, it’s really annoying that on such expensive vehicles GM ditched the 12v port but didn’t increase amps to the USB to still power peripherals like tablets (or radar detectors). It’s be even more annoying if I’d gotten a ticket because my radar detector looked like it was working but wasn’t.

Excellent alternative to the original power supply that uses an entire 12V outlet in the car. Instead I use a 3-port USB plug and operate my radar detector, dash cam and phone charger on one outlet.

EDIT: The seller sent another cord right away. I tried the cord as soon as it came in and it does not lose connection. Thanks for taking care of the issue!! Bought this item and it did not work. It had a loose connection and would not stay on. Just a waste of money.
