It would make sense if you could power other pedals though TU-3’s battery. But, Boss clearly states that this power passthrough is only available if you use a power adapter. If you’re planning on using the pedal regularly, it’s best to ignore the battery altogether and buy a power adapter. The battery option is there if you need it, but really you should fit this tuner on a pedalboard. Power Passthrough

The TU-3w is the Waza Special edition and features even brighter LEDs, plus a much higher spec internal buffer. All Boss pedals include FET switching, and with players adding high-spec audiophile grade buffers to their boards these days, Boss have made the TU-3w to combine two utility pedals into one and save us all a bit of pedal board space. The TU-3s is smaller and switchless, it's great as a bench tuner for techs or on pedalboards with volume pedals that have a bypass output. Essentially it's a space saver for people that don't require tuner switching. In any case, even if you find it useful, don’t count on this being the long term solution for all of your pedals.

For this power passthrough, Boss recommends that you use their 200mAh or 500mAh PSA power adapters. In case you’re using the 200mAh version, this means that you have 170mAh for runing other pedals in the chain. But, this is only true you’re runing the tuner in normal mode. In high brightness mode (more on this later), the tuner draws 85mAh, so only 115mAh is left. The inputs on the Boss TU-3.
