Does not fit Google Nest WiFi access point
This does not fit a Google Nest WiGi access point. The barrel of the male end is too thick to fit in the recessed hole in the unit

Excellent all-round quality.
This is a really good quality, well-made extension cable for (certain) Alexa devices. Unfortunately, this was not suitable for mine (I should have checked!). The cable sheathing is a good thickness and robust (not brittle feeling), the connectors being of equal quality. The collars are strong and extended to help resist fraying etc. This is just the job if where you are placing your device is too far from a socket outlet, and a much neater solution than using a trailing extension etc. As noted above, this is very well-made, and had been intended to be used with my 2nd gen. Echo Show 8. Unfortunately, I had inadvertently ordered not realising it doesn’t fit! So, do check before purchasing to ensure it is the right one for your device! It is though great quality and reasonable value. I hope this has been helpful.

Does not fit Echo Show 5 Gen 3
While the male aide fit the Exhow Show, the female end of the extension does not fit the male side of the original Echo Show Gen 3 device despite being g stated as compatible.

Thick wire and firm connectors
🔌 I have been testing this extension cable designed to extend the existing power cable for a variety of earlier echo devices. You need to pay careful attention to the compatibility list to avoid disappointment. The cable is black with two cores, and you simply plug it into your device and then plug in the existing power connector to the socket at one end of this wire, and you are done. It couldn’t be easier. 🔌 I was very pleased with the construction of the extension and how it performed. The connections were good, and I really like that the wire is robust. I received the 3M version because I was worried about losing power with the longer 5M version. It is definitely recommended for your legacy echo devices, but it could be used elsewhere if you have a compatible device that needs an extended power lead. ✔️

Dose not fit the home hub as it was advertised to!
Dose not fit the home Google home hub. To boot the one they sent me was a resale item. Quite disappoing.

Rallonge 12V DC 5M, fiches mâle/femelle "standard" (diamêtre 3mm)
Cette rallonge courant continu de 5 mêtres est standardisée. Elle est donc compatible avec un type bien particulier de fiches 12V (1,5A) normalisées... qui sont assez couramment utilisées par divers petits appareils domestiques. Mais souvent la longueur du cable DC venant du bloc secteur 220V d'origine, n'est pas bien long... pas assez long ! On se retrouve ainsi à devoir, déplacer ses devices (enceintes bluetooth portables, écrans connectés divers...) au plus près d'une prise de courant, où alors à mettre une rallonge secteur disgracieuse : Cela n'est pas pratique ! Avec cette rallonge de 5 mêtres, le bloc secteur reste toujours branché directement sur la prise 220V... et votre device lui, peut rester posé à l'endroit de votre choix. Je l'utilise en ce moment pour recharger une enceinte portable Cabasse Sweel; mais cette rallonge convient aussi pour mon Amazon Echo Show 5 (1ère génération), voir pour d'autres petits appareils électroniques, s'ils sont en 12V... et qu'ils ne consomment pas plus de 1,5A.

La construcción de cobre 18AWG garantiza que no solo sea duradera sino que también proporcione una fuente de alimentación confiable.

Valido para mi camara solar
Tengo una camara de vigilancia que se almienta de un panel solar, pero el cable no llega desde la zona donde tengo la camara hasta donde da el sol (cubierto por arboles) asi que pedi este cable que me ha servido de maravilla. Con 5 metros he tenido de sobra para llevar el panel solar a la zona del tejado donde siempre a el sol.
