ça marche
Fait parti d'un petit montage dans la voiture pour alimenter le boitier Android Auto sans fil. Le boitier est bien alimenté uniquement quand le moteur tourne. (la connexion se rétablissait avec le téléphone quand je sortait pour aller dans le jardin ou que je bricolais dans le garage). Problème résolu, ça fonctionne depuis 15 jours.

Work Perfectly
They work as intended, I'm using one with a Raspberry Pi (running Octopi) attached to an Ender 3 v2 printer to enable controlling the printer via Wi-Fi. Apparently you can damage your Raspberry Pi if you allow the Ender 3 v2 USB port to back feed power into it. This adapter severs the power lines while still allowing the two devices to communicate properly. It's far more elegant then modifying a USB cable. Devices wouldn't communicate at first but it was a bad cable not this adapter so make sure your USB cable is good.They're great value for the money, they can also be used to help eliminate USB power noise on some digital audio interfaces like the Scarlet series for example.
