I’ve received a lot of help from this forum so thought I’d contribute a tip.
I bought this wall charger from Inspiretech via amazon when I ordered my wife’s 2GB Fuze. It only costs $.05 + $2.98 shipping to all 50 states. I received it within a week of my order. I’ve charged the Fuze with it twice so far and it works perfectly. Music playback works while the Fuze is being charged.
Of course there’s always a chance of getting a defective unit which might fry a Fuze. I’m just relating my personal experience which has been very positive. I don’t have an affiliation with Inspiretech or amazon whatsoever.
To find the charger on amazon, do a search on “Travel charger for sansa”.
