boAt Stone 190 5W Bluetooth Speaker (Black, Stereo Channel), not New, Slightly Used, Worth ₹1500.

This boombox of a speaker has helped me in many occasions. It may look small in size but this 5W speaker. The 52 mm drivers provide for smooth playback for about 3-5 hours in Mids (i.e. in around 50-60% Volume)

Features -
• It's Condition is good as new one,
• Gently Used,
• Working Perfectly, Come check it freely
• Power Output(RMS): 5 W
• 52mm drivers
• Battery life: upto 3 to 5 hours in Mids
• Wireless range: 10 m
• Wireless music streaming via Bluetooth

Note: to be on safer side, I mentioned the battery backup as low as possible, but it can give more than that backup,
And what u see on Google or WhatsApp battery backup company claim, is measured in 50-60% Volume only.
