I started out thinking 3, max 4 pedals were sufficient. So I got me a small board and PSU and daisy-chained. Problem is, I'm not very GAS-resistant, and so before long, I bought another small board, another PSU and...
For some time I carried two board, PSUs on a multi-plug and two very vulerable looking cables from the PSUs to the board.
Then Thomann had a special offer for this one, and I did not gave to think for long. Now I only have to tout a single package, and the supply cable looks reassuringly sturdy. What a joy! I coul even run it on the in-built power bank, but I'm afraid of running out of energy at the end of a concert (would do it, if guaranteed less than an hour, specs are 90 minutes).
Highly recommended buy.
