			 OK Chad and Anthony 
		
	
		
		
		
		
			I propose each of you conduct tests with your respective Canadian Tire bought units and use your most efficient powerhead in terms of power consumption and water movement (aka Tunze) and give everyone an approximate time that the charge lasted to keep the powerhead running. Things to note should be something like as follows: Power Unit - model and make Powerhead used - model, make, watts rating Length of time - hours and minutes If you could do the test for us and let us know the results. I also know the battery pack unit that Anthony has can be recharged by plugging into the cigarette lighter. If you could let us know how long it takes to charge it up with the cigarette lighter.

			 Unfortunately I sold my Tunze (too powerful for 3' long tanks). I have Seio 1500s, but I think I would plug in my 4.5w Hagen Maxima air pumps for the fw & the Seios (26w) or Maxijets (20w) on the sw. I also have another spare Maxima so if it looks like a long outage, I'll plug that in instead for circulation. Our central heating system is natural gas so hopefully that will still work & I won't need to worry about temperature. 
		
	
		
		
		
		
		
	
		
		
	
	
	My Motomaster Eliminator is the 300 amp version, not the 1200 amp like Chad's. I think for you guys (Chin & TomR), the 1200 amp version would be best, but I got mine on special (1/2 price) so that's why I went with the 300 amp one. I also had another small battery pack & I will be picking up the battery operated air pumps for back up to my back up Chin, if you want to test it out on your Tunze, you're welcome to borrow it.
