Sonos One speakers are not battery powered—they require a constant connection to AC power through a wall outlet. Each Sonos One includes a power cord and must be plugged in to operate. This wired power requirement differs from some other smart speakers on the market, such as the Amazon Echo Show 15 or certain portable Bluetooth speakers, which offer battery options. The trade-off is that Sonos One speakers deliver consistent, uninterrupted power for continuous music streaming and smart home integration without needing regular charging. If you need a portable, battery-powered Sonos option, the company offers the Sonos Roam speaker, which has a rechargeable battery and can run wirelessly for several hours per charge. For stationary use in homes, the Sonos One's AC power requirement is typically not a limitation, as they're designed to be placed on shelves, nightstands, or other fixed locations near power outlets.
