The Koma Elektronik Strom Mobile Portable Power Solution provides the concept to supply your equipment with power on the move. The device itself draws its power from 2x USB Powerbanks, powering up to 4x devices with 9V/12V DC. The current consumption per string is indicated by an LED monitor in 250mA steps. The Strom Mobile includes an input current feedback system to prevent exceeding the maximum output current.
The main features of the Koma Elektronik Strom Mobile Portable Power Solution include:
I am very happy with this purchase. Powering your guitar pedals from a powerbank is an easy way to get rid of ground loops. Sometimes, still, the voltage converter adds a little noise. Not with this one. The fact that you can see how much current is drawn is not a gimmick, but allows you to see if you are running close to your battery limits. Slightly disappointed the product comes with a reduced set of cables (1 USB and 2 power outs, when the device has 2 USB inputs, and 4 power outputs). So, best purchase the cable pack sold by Koma too.
