This (PC9290), the only battery powered router (in is day), is a fun luxury that may pay for itself in the busy shop. You will buy convenience and safety not having to haul wire around. The router can also go where there is no power, like in the hull of yacht in production or in an airplane.
The 600 watt (~1 HP) tool is handy, quiet, lighter (7.6 pounds) than its A.C. brother (8 pounds for 690) and behaves nearly the same.
The machine is supplied with one 19.2 volt, 2 amp/hour battery and charger. The life of a charge is quite dependent on the duty cycle and load you present to it. For the quick single shot work I use it for, it lasts for weeks. Rounding over 2x4"'s will kill the battery in less than an hour. The battery locks well in the casting head and can be changed without effort. Obviously, the battery can be used in many other PC tools.
The battery does concentrate some weight a little high up so there is a minor amount of instability but essentially none with their (cat. no. 42193) offset subbase. The router can be used where ever the 690 has application but I would restrict its use to short burst experimental cuts. This is not a production tool.
Supplied with only a 1/4" collet, it is anticipated the machine is only for light work. Notwithstanding, you can and should use a 1/2" collet when ever possible.
The single speed hard start motor spins at 23K and is relatively quiet. It is supplied in the standard 1001 (690) base casting but can also be used in the d-handle and plunge bases. You can use 2 wrenches on the armature or one with the spindle lock. The safe motor north/south travel is ~1-3/4".
I have one for sale, I rarely use it.
