Delivered quickly. Looks sturdy and durable. Comes with nice case with compartments where all components can be stored in organized manner. Charging of mobile through QC was quick. The DC out port was able power my air pump (connector and pump bought separately). I have not yet tested the jump starting.
The 1500A model battery weighs 730 grams, the whole package is more than 1Kg, I don't think I shall carry it for my travels, but still okay to keep in the car.
There is no LCD screen so there is not much visual feedback of whats happening.
