Bests & Worsts Reviews from Amazon

I know nothing about electronics and computers or chargers for electronics and computers. Fortunately I have sons who look out for me. My son said .... mom, get this. I did. Now I am recharging my cell phone lightening quick and there is a 2nd whatchamacallit if someone else is in the car and needs to recharge their phone. Why it works, I don't know. But, it works and I'm very happy with it.
