Re: Priups - 1kW real world test
. . .
I have a spare car battery that I keep fully charged (always on a multi-phase charger) that I brought in, hooked an 800 watt MSW inverter, and plugged the coffee pot into that. I maybe got two cups brewed before the "beep-beep-beep" of the inverter started up, I had to "re-seat" the battery (spring) clamps and maybe got another cup brewed before the battery was below the tolerance of the inverter, 10.5 volts.
If a full size 12 volt car battery with HIGH starting current capacity cannot provide ~800 watts (~60 amps), for the 5-10 minutes it takes to brew a pot of coffee just how long will the 12 volt "low" current capacity supply more than 10.5 volts.
