Spark Control comes with a built-in battery. For charging, it is recommended to use the supplied cable with a charging brick (not included) that features a USB port and supports at least 500mA charging. Charging via computer is not recommended.
Alternatively, any 9V center-negative power supply used for powering most guitar pedals can also be used to charge Spark Control.
The battery will last 150~200 hours on a single charge.
Does this mean a large or small iPhone charging brick will charge a Positive Grid Spark foot switch? Thanks
THis is the kind of brick you’ll need

Not sure all iPhone charging brick will do. Also, you’ll need a center negative connecter as there is no usb plug on the footswitch
