Smallest kali linux wireless adapter?

What is the smallest kali linux compatible wireless adapter money can buy? Small thumb drive style with compatible chipset.

Smallest I have found Edimax EW-7811Un 150Mbps 11n Wi-Fi USB Adapter

Looks good. Do you think it supports all the Kali features? Packet injection/monitor mode etc?

I don't see a chipset listed with which to confirm, but I'd check the forums here & at aircrack-ng.org. Maybe someone else has tried it.
