I recently purchased a Sony Vaio Laptop and Additional battery - it came with the following power adaptor: Input 120-2540V~1.5A 50-60 GHz & Output 19.5V 4.7A w/ a polarity of - solid circle + I have an HP Slim Travel Power Adapter that I love - it's lightweight and small and easy to carry - but the specs are slightly different: Input 120-2540V~1.5A 50-60 GHz & Output 19.5V 3.33A w/ a polarity of - solid circle +. What Impact will the lower 3.3 Amps have?
