that's a bit strange... if you buy a single one for 159.-, the adapter is included, i.e. if you buy five, the part costs 795.- .... if you buy a 5-pack, the part without costs 699.- :: results in a difference of 96.- ::: but then you still have to buy the parts for 29.- each.- :: results in 145.- costs. as a result of this, you pay 49.- more for the 5-pack. is there a reason? or is the whole thing delivered in a nice gift box...;-) or is someone standing on my wifi...?

Correct, the injector is included...

Hello everyone, I also have two questions.
- Is the injector (from LAN --> POE) only in the single pack or also in the 5-pack?
- Is it a cable with a swiss or euro plug?

Thanks to you

Some answers here are out of date.
The PoE injector is only included in the single pack.
Not only the 5-pack, but also the 3-pack is supplied without the injector!

! Watch out, because this question also comes up with the almost identically named Ubiquiti UniFi AP AC-PRO-E (with -E at the end):
The -E variant does NOT include the injector! An additional injector (e.g. Ubiquiti Passive PoE Injector: 48V, 24W) must be purchased. This is also stated in the product description.

Exactly. It's in.
