I'm posting this on behalf of L1® owner JB95.
"Tom-at-Bose answered the question comprehensively for powering an L1 Compact with an inverter. What power inverter would be required to run a T1 ToneMatch as well as the L1 Compact?"
Here's the background information.

Informational Post: AC Power in for L1 Compact
This is especially for those who want to run the L1 Compact with an inverter connected to a car battery or from a Power Pack.
Note: The L1 Compact accepts all AC Power In voltages from 100V to 240V, the different part numbers change the power cord in the box.
Here are the AC Power in levels we have measured on the L1 Compact, please realize that these are approximate and vary greatly with audio content.Power 230V 120V 100V Idle: 12 W 0.06A 0.1A 0.12A (no audio out) Filling a room: 30 W 0.14A 0.25A 0.3A Full Out: 60 W 0.3A 0.5A 0.6A (Red LED blinking)
Note: The AC line power in can peak around 100W during a loud burst.
We have also tested the L1 Compact with several DC to AC Inverters, mostly the low cost "Modified Sine Wave" (actually three level square wave) ones and all have worked very well, there is no buzz problem from the ones we tried.
I recommend that an inverter of at least 300W be used ($30 to $35 US), less then that has not been tested.
Here are measurements we took, realize this also includes the inverter efficiency:Current from Power 12V Battery to Inverter Idle: 12 W 1.5 Amps (no audio out) Filling a room: 30 W 3 Amps Full Out: 60 W 6 Amps (Red LED blinking)
There are also "Power Packs" available which have the battery built in with the inverter.
To find out how long one of the "Portable Power Packs" will run divide the amp hour rating of the battery by the amps from the list above (usually divide by 3), this is assuming it uses a 12V battery.
Hopefully you folks find this information useful,
