Brand new item arrived already stained

The item arrived with a visible, indelible stain on one of the faces. The overall design and quality are in line with what I expected, but this kind of cosmetic defect on a brand-new decorative item is disappointing. A stricter quality check before shipping would have been welcome. A shame, because the product itself is otherwise pleasant.

Steckdose fast geschmolzen / kein Support!

Steckdosenwürfel ist so heiß geworden, dass sich der Kunststoff verändert hat. Im Inneren begann es zu summen und Teile klapperten. Ich habe mich vor 8 Tagen an den Support gewendet und bis jetzt keine Antwort erhalten. Die Steckdose lag neben meinem Bett. Ich bin froh, dass ich nachts nicht abgebrannt bin. Es ist nur durch den Wechsel der Nachttischleuchten aufgefallen.

Mega chic & praktisch ;-)

Was soll ich schreiben? Ein toller Würfel welchen ich in einem Design-shop gesehen habe. Farblich passt er genau zum Mac und ich kann direkt per USB-C mein Phone, Mouse, Tastatur... laden & die Steckdosen für Laptop etc....bin total happy damit. und Dank Magnet "klebt" er an meinem Tischbein...einfach toll.. DANKE ;-)

Sadly broke after 30 days

My unit worked well for approx a month but then it got bulky on one side probably due to some co structuring fault and seems to be overheating - hence the usb C ports work very randomly and tend to cut power supply. Will be refunding

Broken out of the box

I ordered a pack of three Square 1 power extension cords. The product is designed nicely and comes in premium package.

However, out of three, one has a completely loose part inside that rattles all around the inside of the enclosure. The enclosure can't be open to potentially fix the problem (no screws or other disassembly solutions visible). The power outlets and USB charging ports work, but the premium aspect is completely gone and the safety of the device is questionable at his point.

At this price point and marketing communication, one would expect a solid build and decent Quality Assurance. Instead, you're getting a lottery. I hoped for something that will bring minimalism and simplify my space. What I got was disappointment and having to figure out how to go through the labyrinth of warranty process.

I wish you better luck, and discourage you from getting it as a gift as you won't know if your unit is faulty or not.

Total praktisch und nützlich

Dachte erst, ganz schön teuer - aber nützlich als Verlängerungskabel und IPhone und iPad Ladestation. In Kombi mit der Magnethalterung 🧲 an unserem Küchentisch fantastisch nützlich, etwas was man echt gebrauchen kann, wo sich ein Produkt-Entwickler echt mal Gedanken gemacht hat; die guten Dinge sind SOOO EINFACH, man muss nur erst mal drauf kommen.

Avolt Plug Extension: Minimalist Design Meets Everyday Functionality

Avolt has taken something as ordinary as a plug extension and transformed it into a statement of design. Packaged with the same level of care and presentation you’d expect from Apple, the product immediately conveys a sense of premium quality.

The unit itself is sleek, understated, and elegant. I chose the black finish, which pairs perfectly with a silver-and-black MacBook Pro setup. It looks just as good on a desk as it does tucked neatly on the floor, though its pristine finish makes you want to treat it with the same care as any high-end accessory.

One standout feature is the integrated magnet. It’s impressively strong — perhaps stronger than expected — ensuring the extension stays put. Still, an additional magnetic base, or the option to purchase extras separately, would add even more versatility around the home.

There are a few refinements Avolt could consider: a cable that’s slightly longer, and colour-matched cable management straps to elevate usability. The black finish also attracts fingerprints, but this is easily remedied with a quick wipe.

Delivery was efficient, the outer box easy to open, and the unboxing experience satisfying. Overall, this is an 8/10 product — functional yet aspirational. Avolt is fast earning its reputation as the “Apple of plug extensions,” and if this is a sign of what’s to come, I’ll be first in line for their next release.

Stylisch und hochwertig

Die Verlängerung lässt sich sehr gut und einfach mit Hilfe der Magnetplatte an Rückwänden von Nachtschränken befestigen. Die Farbe ist sehr schön und die Möglichkeit drei Steckdosen zu nutzen ist perfekt. Mich überzeugte das Design und die Innovation des Produktes. Ich habe auch die andere Variante mit Steckdosen und USB Anschluss gekauft und finde auch diese super.

Schock, ich kann es kaum glauben

Ich kann nur hoffen, dass es ein übler Scherz ist. Diese teure AVOLT-Steckdose wurde ohne Originalkarton einfach im Umschlag(?) ohne jeglichen Polsterung mit schon aufgeklebten Fixierungsaufkleber, Schrammen und Gebrauchsspuren sowie klappern im Innenteil aufgrund defekter USB-Buchse versendet. Schock! Ich haben schon eine AVOLT-Steckdose, und ich weiss bei dem Preis wie hochwertig der Originalkarton ist und welche Zusatzteile vorhanden sind. Ich bin wirklich fassungslos und irritiert über diese Art und Weise Kunden so mit „Müll“ zu beliefern. Ich hoffe wirklich man hat sich vertan: Anstatt in den Elektroschrott zu hauen hat man es aus Versehen verschickt. Man kann darüber echt nur lachen weil es so skurril ist. Retour heute mal sehen ob ich mein Geld wieder bekomme.
