... same question but 240v and 50~60Watts ...
I am starting here : 300W - 12V Pure Sine Wave Sunshine Power Inverter - Sunshine Solar - Sunshine Solar Limited

I have a Beaudens, but I haven't kept up with brands over the past couple or 3 years. My only recommendation would be to check reviews on the web/YouTube. There is no shortage of YouTube reviews, it just takes judgement to decide which to trust.

How long would a fully charged 12v car battery last with your 50 ~ 60w amp? TIA

Assuming everyone is looking at Class D amplifiers. Inverters don't last long with Class A tube amps.

I have no experience with 240V inverters. Lots with 120V AC models. Anker is the best. Available on Amazon. Look for cost history and sales. Should cost just over $200 in the power range suitable for driving amps at gigs.

Based on average figures:
60W consumes 5A at 12V (lets not talk about surge currents and efficiencies).
Assuming you want to leave approximately 70% capacity to ensure the car starts after the gig, a 45Ah battery will give up 13.5A. That equates to about 2~3 hours of gig time.
