The charger works... But very slowly! Took nearly 4hrs to charge my phone (a Samsung Galaxy S3)!!! I bought it because the original charger that came wih my phone wasn't working properly. My mistake was ignoring the output current (0.6A). I would not recommend this product to anyone with a phone that originally came with a charger with an output current much higher than 0.6A (e.g. 2A). Otherwise, it's fine.
