Query: Works only with charge, not plugged in

I hate rechargeable gadgets whose battery needs to be changed every few years. It is the way manufacturers get a semi-yearly fee from you for something that would work for 20 year like my previous Braun shaver. This shaver is one of those. I had assumed that even if it is rechargeable it would work when plugged in, like my laptop. I was wrong and I returned the product.Braun Free Control 1775 Men's Shaver
