My Signia telecoil rechargeable aids get 36 hours of use, if I recall correctly. I’ve never come near that amount of hours of constant use, so I can’t say. But I don’t stream much.
the variety of useable hours people report for their rechargeable aids amazes me. It’s all over the map.
Big, bulky chargers? Not mine. My main one ways about three ounces. My travel charger, that holds three full charges, weighs the same and fits easily in the palm of my hand.
