Works as advertised. Blocks the power. I use it with an Android Auto external device because the data+power USB port in my car remains active for an extended period after turning off the car. So I added a splice to draw power from another port (that is off when the car is off) and then only allow data in the primary port. Works perfectly.

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.

Kör Octopi / Octoprint med min Raspberry Pi till min 3D printer. Denna blockerar strömöverföring via USB vilket var exakt det jag var ute efter. Produkten skulle kunna vara ännu mindre i storlek, om man får önska något.

Hace lo que promete.

Bloquea de manera comprobada la energía del puerto USB del ordenador, permitiendo alimentar independientemente del ruido eléctrico del puerto el cable conectado al conversor digital.
