Modding Bose QC20 to use dc power?
My bose Quietcomfort 20's battery is dead... I know some online vendors sell compatible batteries and controllers and there are videos on youtube explaining how to replace them.
However, since I mainly use the qc20 at home for noise-canceling and don’t need/want to keep buying li-ion batteries, I wanted to know if there is a way to attach an external dc power adapter instead? The battery is 240mah 3.7v, I'm not sure how to find something like that in a power adapter. Any ideas?
