The first thing to bear in mind is that this is a battery, not a mains converter. Charge it up before you want to use it. If you think you may forget to charge it before a gig then you're probably better off buying something else.
That said, this is a great value bit of kit. I use it to power three pedals; Boss TU3, EHX Bass Muff and EHX Pitchfork. This gives me a full gig and rehearsal from one charge; roughly seven hours. It is absolutely ideal for this kind of setup. It comes with enough cables to power up the kind of rig that you'd sensibly use from this supply. It comes with various mains adaptors and can be charged via USB as well which is very handy.
There is an LED indicator on top so you can keep track of how much charge is left. The power button requires a double press to switch on. This is actually pretty handy as it cuts down the possibility of being switched on accidentally while it's in your bag, draining the battery before the gig.
Coming in much cheaper than a Pedaltrain Volto, this is an excellent value bit of kit if you use a compact setup.
I bought this as a cheaper alternative to the Pedaltrain Volto, and initially it did all it was meant to do - around 3 hours charge when using 4-5 pedals, plenty for the average gig. I was happy to ignore the temperamental power button that always needed a couple of presses to switch on, as it was still powering the pedals when I needed it.
Then one evening I realised too late that I hadn't charged the PSU before my gig. "No problem", I thought, "I'll just plug it into the mains and charge it while I'm using it. After all, you can still use other electronic gadgets while they charge up- this should be the same, right?" WRONG!! Apparently Warwick haven't mastered the technology that allows an electronic item to work while charging, so if you must buy this, make sure you remember to keep it charged before you need it or, like me, you'll be rushing out to buy some 9v batteries!
