I have both a blender and coffee grinder. I run them through my 200 amp inverter that is plugged into a cigarette lighter outlet. I run it off my van right now - my
Scamp isn't quite ready for action. Because it is seconds of use I have never had a problem. My blender is a basic $15 Wal-Mart special I think it is a Hamilton beach with only a pulse button which gives me control. My coffee grinder was from a thrift store and I checked the wattage before buying - its a 60/100 peak if I recall correctly don't have it close enough to check the brand.
You can do it. Worst is a breaker or fuse replacement which is easy peasy.
