After my cat destroyed my 770 charger (the AC-4U), I scrambled to find a compatible one; I finally managed to find an AC-3U, which seems compatible based on the Nokia accessories page (i.e., the same models listed for the AC-4U are listed for the AC-3U). Now, my grasp of electronics isn't what it could be, so I'm not sure if I should be worried or not: while the two chargers share the same DC output voltage (5V), they have different DC output amperages (890mA for the 4U, and 350mA for the 3U I bought to replace it). Is it safe to use my new charger?
