Hi guys, so this is an instructable for people who love carrying around their music with them as well as hates carrying around their phone charger searching for a power outlet ;-) .

This is simple cheap and easy to make portable bluetooth speaker cum power bank just the size of a normal 5 inch smart phone which can easily fit inside any pocket.

This decive has a 5000 mah battery that can keep the speakers going for around 15 to 18 hours or can fully charge your i phone5, two or three times.

The decive case is hand built using MDF which I found among the trash in the basement .I chose MDF as its easier to work with and finish and it wont come off in layers

The speaker consist of a 2 inch driver which I took out of a broken desktop speaker along with a 62 mm circular passive radiator .The passive radiator improves the bass to a great extent.

The total amount I had to spend was just 13 dollars (₹845).
