Just checked out the Panasonic web site. First thing that struck me were the prices! $510 for the top cordless drill model (15.6V Multi Drill & Driver with 1/2" Keyless Chuck). As you say, all nice and compact. But the high price made me think that Panasonic tools must be an elite brand. Then checked out prices for these very same Panasonic models at several online retail tool vendor sites, where I found the prices to be much more in line with the competition. For example only $299 (virtually half the price) for the above model at Tool Authority (http://www.toolauthority.com/manufacturers.php?MID !). One observation though, in general the Panasonic cordless driver lineup seems to offer somewhat less torque than competition such as Hitachi or Bosch drivers, even in models where the voltages are the same. But I guess the extra compact design of the Panasonic drivers I guess could very well account for this.
BTW, another question I have just came to mind: what is the significance of "Ah" (e.g. 2.0 Ah, 2.5 Ah, 3.0 Ah, 3.5 Ah, and so on) rating of a cordless tool's battery-capacity? Up til now I had just assumed this referred to amperage-per-hour output (which, like the amperage rating of a corded tool, if multiplied by the voltage [e.g 12. for 12v. cordless models, between 110 and 120 for all corded models] yields maximum energy output [or consumption, respectively] per hour). But I'd like to somehow find out for certain from someone if I am on the right track in this or not... Because if this is true how can the most powerful cordless tool possibly keep pace with an average corded one which has far higher, both, amp and voltage numbers? Thanks.
