A:Answer Hello Gary! As with most Bluetooth Speakers on the market, we don't have an output wattage for the WONDERBOOM SE 2-Pack Portable Bluetooth Small Speaker with Waterproof/Dustproof Design. Instead, the sound power of Bluetooth Speakers is evaluated in decibels, and so the WB2 has a max output of 86 decibels; however, the WB2 has Stereo linking capabilities (link to another WB2 which will effectively doubles the "loudness" as each will produce 86 decibels) as well as "Outdoor Mode" to increase overall sound from 86 decibels to 87 decibels. - Mathieu from Logitech
