None of them can "really" do both lighting and charging at the same time. It's a matter of limited power from the dynamo itself.
The Luxos U can technically charge while the light is running, but the draw is extremely extremely small. Not enough to charge a cell phone if I remember right.
I believe the Luxx70 does also have integrated charging, but it's not a very good light. The Luxos U also has a cache battery to smooth out charging, which I don't think the Luxx70 has.
