Review on Portable Charger R540SA R540LA Adapter by Matthew Liebenstein

This adapter is a terrible waste of money. It barely charged my laptop and couldn't keep it running for more than an hour. The fact that it's portable is irrelevant when it doesnt work. Thanks to my knowledge gained in practice I have to say this adapter is not suitable for computers. The only positive thing I can say about it is that it looks nice, but that's about it. It's not worth EVEN a fraction of the price .Save yourself the trouble and find a different product..
