So there I was lugging WZ around in Ikano when I saw this thing in the RC Planet shop on the top floor.


At first I thought it was an inverter, which essentially is a device which takes a DC power source (ie, you car battery) and convert it to AC power (ie. the wall socket in your house) for more info read my previous post. But then I thought no one would simply label something as a generator if it was converting power, and I found this spec sheet stuck on the cabinet.

It's essentially an inverter… that comes with a battery. In layman's terms, this is a wall socket which you can carry around! The rated power output is (in case you haven't clicked on the link yet) 140Watts CONTINOUSLY I wonder what the peak rate is then.

The power capacity is 210Watthour, base on what little I know of power calculation I think the rough formula for seeing how long the thing can last for you is to take the wattage of your device say.. a laptop charger that has a rated MAXIMUM output of 12V x 3A = 36 Watts and then use that to divide the maximum power capacity so in this case it's 210Wh / 36W = ~5.8 hours. So, if your notebook charger was constantly drawing the peak power rating, you'll get about 5.8 hours from this thing. But I don't think notebook adapters go near their maximum power rating, then again it's not like I have any equipment for measurement.

It IS an interesting piece of gear to carry around, especially if you had something you wanted to power in the middle of no where. Just be mindful of the power rating for the equipment you are running. Traditional tube TVs are a no no, cause the degauss cycle they go through when you turn them on draws a lot of power. Ditto for hair dryers, and probably power tools. At 140Watts you can forget about powering your XBox 360 or PS3 in a campsite. Or for that matter your monster rig of a desktop computer. :P

Now I just have to convince myself and someone else that I NEED to get this…
