It's very frustrating, I've been a TPLink Customer since I entered IT world, I have tons of CPE and EAP, my personal and office gear are tplink and each devices have their own power adaptor included in the box, how the f*ck I'm gonna use these without power adapters!?

  @Mellx1 

Not quite on the topic, but I'll write anyway

normal wireless networks use active poe equipment to power access points

There are some exceptions of course, but often these are quite specialized devices

In my opinion, you have chosen the most incorrect configuration of devices

with 2.4 GHz everything is very bad now, in some cases it is turned off completely, or a separate ssid is used for clients that do not support 5 GHz

frankly speaking I don't know why TP Link released business access points only in 2.4 GHz

here eap225 is the right choice, and it would be good to power these access points through a poe switch

I don't see any point in buying anything below eap225

  @MR.S Thank you for the confirmation. I will consider the TL-POE4818G, little low price than TL-POE4824G.

Let me say this. I've been a loyal customer of TPLink Products since I was on college until now, and your products are my recommended on my previous and current company, but this time i'm not happy but very frustrating, this in not fun when you buy electrical devices there is always a power cord or adapters that's always, if not how the heck people will use it!? When you buy a car, there is always engine in it. I can't think of any reasons why you do this to your customers. 

This the not the right way to sell your products, I am force to spend ₱7,870 or USD134.60 for power adapter and im not a wealthy person, if I do not buy these adapters Im not able to use those EAP's, this is too much for me. You totally ripped me off.

It's the cost. The price of 1 unit 225-OD is almost 3 units of EAP110-OD, I'd rather buy EAP110, it's the best option base on for my available fund and my customers are happy.

This can also be seen in the spec sheet. Yes, that sheet is inside the box, I've read that.
