| Post subject: | Vegabond Mini for powering a TV for a presentation? |
I have a 32" LCD television that I'm using for a presentation tomorrow. There are no outlets near where I'll be presenting, so I was wondering if I can use the vagabond mini for that with no ill effects? If that's an acceptable use, do you know how long I should expect it to power the TV? |

This will depend on the TV and how much power it draws. There should be a label on the TV that shows the (V)oltage, (A)mperage and (W)attage. Presumably, it would be a 120VAC TV and used on a 120VAC VML. The VML is 120V AND 120W. V*A=W tells us that it would need to be 1A or less in order to be within the limits of the inverter. How long it will run is also a function of the power draw. The estimated run time on a fully charged battery is 110Wh. So divide 110 by the wattage of the TV to see how long it will run. So, a 100W TV would run for 1.1 hours, or 66 minutes. Again, these are estimates, and without actual testing, we cannot guarantee success, even if all the number align. |

It's 100W, 240 AMP, 1.5V -- so no go? |

The voltage should be either 120VAC or 240VAC or a range like 100-250VAC. If you are living in the US and have the TV plugged in and running in the US, then it should either be 120VAC or it has a range which includes 120VAC. The amperage should be a pretty low number. I would imagine it to be less than 2-3A for a high draw TV. Even if I were to rearrange the numbers to match the expected units of measure, individually they make sense, but together not so much, unless they are maximum specs for each unit. For example 66VAC 1.5A=100W or 240VAC .42A=100W If it specifically says 100W, you will probably be OK. I would do a test run and monitor the VML for heat build up. |

Maybe it's 1.5A -- I don't know...I went to public school. Thanks. I'll do the old "plug it in and hope for the best" test. |
