Is this safe to use for charging?

I picked this is at best buy to use the USB port for my lightning cable and my Bluetooth headphones. It says it will charge 2 phones or 1 tablet but I could swear the iPad mini retina needs more than 5V. Anybody know?

The Retina iPad mini charger delivers 10 watts (5.1 volts at 2100 mA/2.1 amps). That looks like what your Rocketfish charger supplies, so it should charge at the same rate.

The only thing I can add to what Europa has said is that the charger must filter the incoming power better than most of the myriad of iPhone chargers out there. If not you may experience strange behaviors from the phone when trying to use it while charging. The Rocketfish charger will charge the phone fine but iPhones don't play well with harmonics and voltage spikes coming from a charger which hasn't filtered them out of the supply voltage or charging line very well. I have had good luck with Rocketfish products in the past but have no experience with this particular one.
