Just bought a Roam but looking for a suitable battery power bank to charge the Roam when there is no electricity on the campsite. I would be grateful for any suggestions as I am finding this a minefield. We have both Apple and Android phones, tablets so looking for a good power bank that does not mind either. Many thanks

Hi @vinyldobby 

Welcome to the Sonos Community!

I can’t recommend anything specific, but you’ll want to get a battery bank that can deliver at least 1.5 Amps at 5 Volts, which works out as 7.5 Watts.

One that can deliver 2 or 3 Amps would be better, however (10 & 15 Watts).

If you will be charging more than one device from a battery bank at once, you’ll want to get one that delivers even more Amps/Watts as the power will be split between all connected devices.

I hope this helps.


Many thanks Corry P. The base figures are just what I need to cut through my confusion.
