I could use some help calculating how long my battery will last. I’ve tried multiple online calculators.
Speakers: Peavey Monitors with 10 inch woofer, 1.4 tweeter ~ 101 max SPL
Amp: Pyle PFA200 60-Watt Class-T Hi-Fi Audio Amplifier with Adapter
Battery: TalentCell Rechargeable 12V 6000mAh/5V 12000mAh DC Output Lithium Ion Battery Pack
Using this milliamps to watts calculator, I put in 6000mAh and 12v and get 72Wh.
Since my amp requires 60 watts, shouldn’t it last for just roughly a bit over an hour?
I’ve been playing the speakers fairly loud off of this charged pack and it doesn’t seem to be losing so fast. I think I’ve already listened 6+ hours on just this charge.
What am I missing in my calculations? How long should these speakers really be able to go loud on this battery pack?
