This customer called OutsideSupply.com and wanted to find out what the best power inverter size would be to run a blender at a party they were having at the outdoor volleyball courts in his area. He said they normally had power, but there was construction going on and power was cut to the volleyball area. He advised it was too far to run an extension cord.
Here are the power inverter suggestions I gave him:
Blenders can range widely on the amount of power they pull. They also can have a pretty big surge, this is because it takes a little extra power to get the blender motor turning.
The customer advised that he wanted something that would be reliable and could consistently produce daiquiris for the winning teams every week. I was a bit concerned that he was making hundreds of daiquiris. He assured me they only make 3 teams worth of Daiquiris per week. Or around 20-30 daiquiris per night. Whew, This was well within the normal amount of power you could get from a power inverter and battery combo.
So here is what we recommended and why:
Blender 8.2 Amps at 120 volts = 972 Watts
Surge could be 1.75 to 2 times rating. = Almost 2000 watts
So an inverter able to run 1000 watts with a 2000 watt surge would be safe.
Blenders + Ice = Water = Need for GFCI
So we wanted an inverter with a GFCI outlet.
We now knew what our blender powering inverter would have to be:

1500 Watt Sine Wave Power Inverter
This inverter has a 1500 watt rating with a 2000 watt surge, it also has a GFCI outlet which is perfect for this application.
He also got the inverter install kit from us as well.
The customer hooked up the inverter, made the daquris, and advised me to stop by for a game of volleyball and a daqurii either way. I thanked him and said I would if I am every in his neck of the woods. Another satisifed customer.
