Logic & Common Sense
Setting aside scientific data, we can sometimes use common sense and logic to study a product. What are the claims made by the product? Could it possible do what the manufacturer claims? Use a jump start battery pack for example, like a smaller units that fit under your car seat and intended to recharge your dead battery enough to start your car. You are in essence taking a small battery and transferring what energy it has to a much larger battery. Will this work? Sometimes. But is sometimes good enough?
What about solar? If we could recharge a trolling motor size battery in a few hours with a small panel, we would all be driving solar powered cars. But we don't, so you can't. It takes many Amps and much $$$ to do this, and is usually cheaper to buy a generator. In any portable application, or low draw setup solar is great, but it is not ready for the 'Big time'
Enter common sense and logic, and a decent amount of trial and error on our part. We do our best to ferret out any issues with the products we carry so you don't have to.
