This is a life-saver for both studios and playing live. I basically use this to power my entire studio to some extent. I have my iMac, Yamaha HS-80Ms, Torpedo LIVE, PODHDPro, Blackstar HT20, EVH5150iii, Orange Jim Root Dark Terror, Voodoo Pedal Power, Torpedo RELOAD, and I still have space for more.
The LCD screen and voltage meter is extremely useful and gives a great heads up warning if the electricity supply is out of control or risky. It will save and prevent you from losing any of your gear to blow out's, and even has a safety feature built in whereby it slowly powers off everything connected when the power is cut to it, which is brilliant.
Not to mention i use the front USB charger for my iphone, which lets me record video footage of shows without worrying about battery haha!
