Power consumption of Doppler radar units (watts)?

[Waghit]

I am looking at picking up an old model Doppler radar, and was curious if anyone knew what the power draw (in watts) of those machines is. I'm hoping it's low enough that I'd be able to lug it to the range along with a UPS.
Thanks

might be easier to answer if you would include add info like model and manufacturer...

I'm probably leaning to the flightscope kudu or x1 - I've seen those for sale off and on. Will most likely use it in the garage, but it would be nice to know I could power it (for a short time anyway) with a UPS at the range. Knowing the Watts consumption would give me an idea. If you have one, does it say on the sticker what the power requirements are? I'm really wanting the club data, so a new Xi or Xi+ won't do (and the X2 is too much for my wallet).
Thanks
