F18 Coffee Machine

Thanks to this transformer now  I may use my beloved Italian coffee grinding and coffee machine

This unit packs a punch considering its size and weight. It powered everything we threw at it, even our coffee machine, one at the time of course.

I bought it for my Commercial Semi Truck, I used for microwave and coffee machine two weeks with same charge, really very usable.

The usual high quality build of Canon. Focus works fine on my 70-200 f2.8 although it has hunted on the odd occassion. I imagine focusing in poor light would challenge the set up to the max but that is to be expected.I was concerned abou image softness so I set up a test using a 7D and a 5DmkII with the 2x teleconverter on the old version of 70-200f2.8. Both cameras were set up on a rigid tripod with no centre column and had the mirror lock up activated and the shutter was fired by a remote.The 7D was soft from f5.6 thru and improved thru to f11, from f11 thru to about f18 it was acceptably sharp but above f20 image quality fell and at f45+ it the quality was worse than at f5.6.The 5DmkII was astoundingly sharp from wide open all the way thru to f18. It was slightly sharper in the md range (f11-f16) but the sharpness of the wide open images was good to excellent. Above f20 just like the 7D image quality fell until around f45 it was pretty soft.So there you have it is a useful piece of equipment that can get good quality images but the sharpest are in the mid range f11-f18 range. The 5D managed to get good sharp images even when the lens was wide open.

You can use it to prop up your busted coffee table.

My only complaint is it does not make my coffee in the morning while afield.

Great for a portable second screen on the go like at a not-too-busy coffee shop!

I use it for my Mac mini.. always good to have an extra one on hand for any coffee spills ..

Ran fridge, coffee maker and freezer. Good backup!

I needed a stand for a projector hidden under a coffee table and this worked very well.
