I use it for over a year and I am totally satisfied with this diet.
I bought to use in my Pedaltrain pedalboard nano. Comes with scratch, it can be installed quickly and easily in the pedalboard. It is thin and light. It delivers 2,000 mA with 2 9V outputs and comes with several cables that connects 6 pedals. Pedaltrain thought really everything!
I could do a repeat of 3h without reloading having connected pedals 4 above. So I did need power cable, it's great. It can be charged by USB or jack and the loading is very fast growing.
Here we have a great product, ideal for rehearsals and lives on a small to medium nomadic pedalboard.
