Usha Honeywell CL 15AM Room Air Cooler is a very good cooler for a small room like mine.It is very cheap compared to an ac and eats very less electricity so you not only save the upfront cost but also save money in long run.
The added advantage is it is portable and can be taken anywhere, you cannot do that with an air-conditioner. This has wheels! You can take it to your drawing room when you want to watch tv, you can take it to your balcony when you want to read news paper. I wish I could take it on walk with me
It consumes so little electricity that it can also work on your inverter. This is a very useful thing in summer months when there is always a problem of power-cuts.It also comes with something called honeycomb cooling media which is apparently very efficient in cooling down your room.
Its out body is made of up hardened plastic which makes it very durable and long lasting.It has a 15 Litres tank, so you can fill it with water and forget about it for the day.
This is your portable ac!
