my un-modded charger was killed together the lousy transformer attached. then went ahead and modded and revived the charger. working well till today.I poofed my 1st roomba charger. Still dont know why? After modding, voltage chk ok. When plugged in, the light blink n went off. Then the charger RIP.![]()
manage to get about 90-105 minutes of run time with a single charge before light up red, about 50 min for living room, 25 min for kitchen, another 25 min for 1 bedroom. think quite decent run time.

, fix liao, can't work
