Can anyone please recommend me some good WiFi adapters which would be available almost everywhere ? And of course which supports monitor mode and can be used in Poco f1 without any problems. Thanks.
Don't be so lazy.
By the simple search for (Kali) Nethunter + Wlan Adapter, you'll find near a billion threads.
With almost everywhere would I associate Amazon or eBay, because most of thr Electronic stores aren't that well stocked.
First I would try to get one of the best supported, affordable and surprisingly efficient - TP-Link TL-WN722N.
BUT beware of the different model versions, the first is the (v1) one which has the magic chipset.
Look up eBay auctions and maybe you find a reseller who are bought a bunch of them and sold them in addition on eBay.
Most of the private auctions regarding this Adapter are too expensive, even used-one.
I had to wait quite long, then 2, 3 bigger seller start to offering those, refurbished, for € 10.I bought 4 at once, just to have spare.
Aside from these adapter I would rather suggest the Alfa AWUS036neh ('little black one'). They are reliable , Alfa (stands for himself..) and affordable with € 20.
In my opinion towards a bit outdated RT3070 and more for easier stuff.
If you want sth. stealthier then get a generic Ralink 5370 nanos sized, or if you live you in a area where Panda get sold, then get either one of the Micro/Nano adapter and/or one of the portable, like Panda Pau06 etc
Next time just google or forget Nethunter, because this is something which you have to learn by yourself, methodic is optional, but this is not for Beginner or anyone how mistakes this with an easy-breazy Win7 walk-trough(scnr), rather a very complex distribution which demands hours/years of training, regards of the level which someone is willing to achieve and therefore read, train, read.. Anyhow, don't follow every hype, like every 1 1/2 person who's nowadays interested in this rom.

PS
I have a Oneplus, but with a good Y-Otg adapter, an Alfa Adapter like the Alfa Awus036NHA in combination with a battery pack at least should the Poco definitely be able to run.
