I find it difficult to get excited over a bag of pig tails, but due to the vendor pressuring me to leave a review, here it is: The cables seem to be well made and of the two that I have used so far an adequate amount of electricity appeared to be flowing through them. The small icon on my laptop illuminated to indicate that A/C power was being used, but I didn't notice if the % of battery changed any during that time. Currently, I have no reason to recommend a different product.
