Do you ship worldwide?
Yes. We provide free shipping to over 200 countries around the world. However, there are some locations we are unable to ship to. If you happen to be located in one of those countries we will contact you.
What about customs?
We are not responsible for any custom fees once the items have shipped. By purchasing our products, you consent that one or more packages may be shipped to you and may get custom fees when they arrive to your country.

For some shipping companies, it takes 2-5 business days for the tracking information to update on the system. If your order was placed more than 5 business days ago and there is still no information on your tracking number, please contact us.
Will my items be sent in one package?
For logistical reasons, items in the same purchase will sometimes be sent in separate packages, even if you have specified combined shipping.
If you have any other questions, please contact us and we will do our best to help you out.

bonne alimentation fonctionnant. A vide, mon voltmetre et l’alimentation sont en accord à 12V et à 5V. En revanche, vers les 30V mon voltmetre indique 36V. Peut -etre faut il la charger, … ou que je change de voltmetre ! Meme si il y a 3 bornes de sortie, il s’agit d’une alimentation simple entre le + et le “moins”. Le GND est simplement relié à la terre, aucune tension entre le GND et le plus ou le moins..

fatal, pedido para que llegue a mi casa y llegó a un punto que ni siquiera conocía, se dejó después de la fecha que aparece como entregado pero así el repartidor lo hizo constar para que el pedido estuviera dentro del plazo de ‘entrega confirmada’ y en el mismo punto de recogida, ni sabían de mi paquete. SI PUEDES PEDIR A OTRO, HAZLO.

Stabilisierung ist hervorragend Der Anzeigewert des Displays liegt ca. 3% über dem Ausgangswert, das sollte besser sein. Vielleicht ist das intern nachjustierbar!?? Ansonsten Lüfter läuft ruhig und selten Spannungsstabil auch bei angegebener Maximalbelastung

Thank you for your feedback! We’re glad you’re happy with the stabilization and quiet fan performance. Regarding the display variance, it might be adjustable internally\u2014feel free to reach out for guidance. We’re here to help!

Vielen Dank für Ihr Feedback! Es freut uns, dass Sie mit der Stabilisierung und der leisen Lüfterleistung zufrieden sind.
