Re: Power Blocks
A quick search for "power cord extension and splitter" will help with bricks blocking the ports. Very short cords just to let the brick lay on the floor next to the strip. I am in the USA so mine are 120V NEMA 5-15, even have a couple C14 converters for getting notebook juice from the 240V rack PDU in the computer room.
Though this does mean more stuff to carry, unless you forgo the circuit breaker and replace, instead of augment, the regular power strip.
