I've been having fun playing my lap steel outside with a Ryobi power inverter in the back of a tube amp. I already had batteries and a charger, and it cost about $60 for the inverter. It did hum with the inverter on the spring reverb tank, so I moved it outside of the amp, and it sounds great

| That's pretty slick! What is the battery voltage and amp-hours? Any feel yet for how long it lasts? That's about a 30 Watt amp, right? I wouldn't expect a power tool battery to last very long but it would be nice to have that kind of portability without having to buy a solid state battery powered amp. |

| Pretty cool method to get it done. I'm also interested in the run time while playing. I have that same amp. |

| Very interesting! How do you connect the amp's chassis to ground? |

I played the 30W Peavey Delta Blues for about 75min with a fully charged 6Ah battery before it drained.
I'll try this with a 1 watt amp this weekend!
There is not an earth ground connection.

As portable as the batteries are, carry one spare and you're good for an average outing. This is really cool.
I'm wondering if a class D amplifier would have a significantly lower draw so that you could run something like a Quilter for a few hours? |
