Not cheap, but works like a charm. I needed a small power supply that could also power a USB device (BT midi adapter). The added benefit of the whole thing is that the pedal board can be wireless and not subject to AC interference at the same tim.

Feels like it's really solidly built with good parts. Love the features so you never have to guess if your power may cut out on you when in use. Really nice to have the accessories it comes with, and with those can power a whole lineup of pedals by daisy chaining. I love the 1000MA rating for both outputs. It allows me to power typical pedals, but also my multi FX pedal. Now, I can just bring this and not worry about power anywhere, or any ground/loop issues. The USB out for charing phones and tablets is a great plus; I've used it to keep my iPad charged when using at gigs. When fully charged, I've used for hours with a multi FX and one tube screamer, and barely made a dent in the charge. Given all that and you can pretty much power an entire board with this, it's an absolute steal.

It will run a bunch of standard pedals for a really long time. You can charge it while using it. From 14% to fully charged during a set. No power cord means a quicker, cleaner setup. It greatly reduces noise. It works with power hungry pedals that require their own power supply. It has a display that tells you how much power you are drawing, what percentage power is left, and how long it will last. It has two outlets and a usb port. You can charge your phone while playing. I've used it to charge Fishman Fluence pickups. It's tiny. It'll fit in a guitar case easily. If you're a gigging musician, you should have one.

Fully wireless pedal board. True bypass tuner, dunlop crybaby, ernie ball volume pedal all draw virtually no current when not in use and this battery was basically endless. It didn't need to be charged for 2-3 months. The current draw meter is really handy. Adding a new digitech freqout pedal, even when not in use, draws 230mah and now the battery only lasts 10hrs (which is ridiculous that the digitech draws that much when not in use), but thats probably your normal load.Expect 10hrs - 3 months. I bought a second battery for redundancy so I can cycle them easily on the board

My pedal board has only three pedals, however one of them takes a lot of power. This allows me to be self contained (no external power supply necessary) and portable. Works like a champ.
