(Low) Power Consumption for USB Flash Drives

I’m also looking for power consumption information from *any* manufacturer. I tried to use a 32Gb Toshiba stick in my car, but it requires too much power. My next attempt was a Cruzer Fit 128Gb but I gather the capacity is too high, frustratingly. I don’t want to buy a 32Gb Cruzer Fit if the next one I try to use has the same issue - seems like a waste of money.
