The second product that I ordered from Aukey is the Aukey 48W 9.6A 4-Port Car Charger. It is retailing for US$16.99 (S$23) on Amazon. I have not seen a similar charger like this from Anker before.
This is the most powerful car charger that I have seen in the market because it is capable of a 9.6A combined output and since there it is a 4-port charger, each port can output a maximum of 2.4A simultaneously.
