Best and Affordable Coolers in Nagpur for PG/Hostel Students???

Summer is starting, and staying in a PG/hostel without a cooler in Nagpur is going to be tough. Can anyone suggest the best places to buy affordable and effective coolers in Nagpur? Looking for budget-friendly options suitable for small rooms.

Also, We are three people living together, and our room is on the rooftop, so it gets extra hot. Any recommendations on specific brands/models that work well in hostel conditions? Thanks in advance!

Ps: We are there people living together
