Hey everyone! I'm not super tech-savvy, but I recently learned that a phone power bank typically has around 20,000mAh, which I think is the same as 20Ah, right? And I heard a car battery has about 12Ah—what does that mean in terms of power? Also, I've heard that a power bank outputs 12V when connected to an inverter rated for 3000W. How many watts can I actually use from it per hour? Would really appreciate any insights, and feel free to share if you think this idea could take off! ?

To break it down: a power bank that's 20Ah at 12V translates to 240 watt-hours (Wh). So, if you were to use a 3000W inverter, you could theoretically run it for about 4 minutes and 48 seconds at full capacity before the power bank is drained! But keep in mind, power banks aren't usually meant for such high outputs, so you're likely to run into limits.
That's super helpful, thanks! I'm actually looking into Bitcoin mining and thought I might need constant 3000W. Any tips for actually getting that power? I'm curious about how to set it all up.
