Charge PS3 and PS4 controllers at same time?

I'm looking for an easy way to charge both a PS4 and PS3 controller at the same time aside from connecting them direct to each system. I have a charge cradle but only for PS3.

I've seen these hybrid cell phone chargers with mini and micro usb. I'm thinking I might try one, but I have a feeling it charges either or, not both at once. I could also use the same cables I normally connect these controllers to the systems with, but instead plug them into a multiport usb to ac charger.

Anyone have their own solution?

Plug both into the PS4 at the same time?

You could also try Sony's official USB charger for PS accessories during the PS3 era: http://www.amazon.com/gp/aw/d/B001KYV9AK/

Any USB charger should do.  I've done that....use a mini and a micro USB cable to connect them.

I bought this a long time ago for my PS3 controllers & it has two USB chargeing ports on it as well, so I charge two PS3 and two PS4 controllers at the same time with it.

You can also just plug them into your PC's USB ports to charge them.
