To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
a must have air pump for all drivers, tiny and powerful, can fit easily in most glove compartments. micro USB charging port, easy to charge with common mobile phone cables, very easy to use with the preset pumping functions, i advise all, specially lady delivers to get one.
i can see that it can support the emergency situations not something you can depend on always. First charging took long time to be completed but i think this is normal with all new electronic products. over all, i like it.
