Here's what Mission Engineering say about the 529i:
The Mission 529i provides eight isolated 9V pedal power outputs and a USB charging port from an internal rechargeable battery
The 529i features 2 x 500mA and 6 x 300mA 9V fully isolated outputs. With a 1A load, the 529i will power your pedalboard for 2 hours on a single charge. Recharge using the included 12V power supply, or from any USB charger.
The isolated 5V USB output can be used to charge mobile devices, or for USB powered audio equipment such as wireless receivers for a completely wireless and portable pedalboard.
The included voltage doubler cable allows two outputs to be used in series to power 18V pedals. Multiple outputs can be used in parallel with a suitable daisy chain cable to power high current devices such as the Line 6 HX Stomp and HX Effects.
All 9V outputs include short circuit and over current protection with red LED fault indication. There is also LED indication of input and output power active, charge state, and a soft touch power on/off switch.
