Features: brand new and high quality 12V 2A for DC input, 10000 or 15000mAh high capacity, small size and simple to carry,Inner Positive(+), Outer Negative(-),Multi-led indicator. The input and output interface is a 5.5x2.1mm interface, which is widely for 9V and 12V digital equipment,9V 1A + 12V 1A output,can powered 1x 9V+1x 12V devices at the same for time. Automatically detect the current charging device model, not blindly output current, smarter and more humane. Reduce the power consumption of internal circuits and batteries during work, increase the conversion rate, and ensure more power output. Using over-temperature and over-current for protection technology to avoid potential safety hazards.
