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~~.

We have also tested the L1 Compact with several DC to AC Inverters. Avoid modified sine wave inverters. Pure sine wave inverters are preferable.

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:

There are also "Power Packs" available which have the battery built in with the inverter.

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.

There was a follow up question about the impact of using a {{T1}} with the {{Compact}}. Expect that adding a {{T1}} may draw as much power as the {{Compact}} meaning that your power requirements may be double what is show above.

Line 326:

The T1 power supply rating of 81-100 VA is the same as 81-100 watts (volts times amps is watts). So I consider T1 maximum power draw 100 watts.

So based on these official specs this setup presents a maximum draw of 300 watts. A good rule of thumb for an inverter would be to oversize by at least a factor of two so at least 600 watts for the inverter.

Keep in mind official specs can be conservative (as Tom's lower wattage numbers show). Feel free to measure your power draw at home using regular utility and/or inverter power. If you have access to a kill-a-watt or similar, it will tell you how much power in watts your Compact and T1 are drawing with your sources at your levels. Sometimes real world testing is best.

Thanks and good luck!
