This is an original Becker microUSB - Power supply with DC output of 5V DC 1A, 13-17 VA 0.5 A. My new Ready 50 ICE with 1200mAh battery is fully charged after 2.5 hours.. I was just very skeptical, because the only 2 3 reviews were very negative. But my choice was probably still correct. This power supply is definitely recommend. My experience with the seller "dani mare" were very good; are very friendly and helpful.
