I bought a larger capacity battery (520 watt-hr versus the 400 watt-hr battery I got with the motor. With the larger battery I can run about 6-7 miles at 3.4-3.5 knots with two people in my compact rib 310. The motor will push the dink up to about 4.5 knots with the same load, but the range is only about 2-2.5 miles then. For just running back and forth from the dock to a mooring the Torqeedo is fine. It is very easy to put on the boat, particularly if you take the battery off. Since there is no gas involved we put ours below on the quarter berth on the sailboat and under the aft settee on the powerboat.

The charger puts out 48 watts and takes about 2.5 hours to recharge the 520 watt-hr battery from a 20% discharge (about 1.2 miles of running). Given that the charger runs off AC and you have to use an inverter to run it, a 20% discharge on the battery takes about 12 amp-hours from the boat battery bank.

As I have said before, there are only two down sides of the motor. First, it comes apart very easily and there is no way to secure all the parts. Because of that we take it home after each use. Of course, that allows us to recharge at home, sot the battery always starts out at 100% charge. With two batteries we have a range of about 10-12 miles between charges. Second, the Torqeedo is expensive compared to a gas outboard. Retail is currently around $2K for the 1003, but you can do quite a bit better at the Defender Spring sale.
One thing I really like about the Torqeedo is that you can run the prop very slowly, which is useful for docking and maneuvering around the boat. You can also go directly into reverse by simply turning the throttle handle the other wat - no gear shift. That really makes tight maneivering easy.

The motor is a bit noisier that you might expect but is very quiet compared to any gas outboard.
