Power adapter requirements for charging Sonos Roam
This article goes over the power adapter requirements for charging Sonos Roam.
For the fastest charge, we recommend charging Roam with a 5V/2A (10W) USB power adapter. A 10W power adapter is available in our shop on its own or included with our wireless charger. While Roam is capable of charging with a 5V/1.5A (7.5W) USB power adapter, you may experience slower charging times.
Insufficient power supply message
If Roam is connected to a charger that is not supplying enough power, the Sonos app will show an Insufficient power supply message in the System tab and in the System settings menu. This usually happens if Roam is connected to a common 5V/1A (5W) phone charger.
If you see this message, connect Roam to a 5V/2A (10W) USB power adapter instead.
