Google like: USB 3.0 quick charge. It's new, but the latest USB protocol for both the highest data transfer and power output. Of course data does not apply with our add-on truck power ports.
I have a GPS app running realtime tracking on my iPad and USB 2.0 cannot quite keep up. It's wayyy better than battery alone, but it still slowly discharges. Some apps are quite power hungry. Of course it's amps times volts equals watts... so 2.1a is not a lot anymore, I'd say you will want 3.1a (per port) minimal (or more of course) for the new devices and power hungry apps coming out.
If u don't need to plan for this, stay with a USB 2.0 port.

OK. My iPad Air 2 OEM charger is rated at 10W (looks like current model is rated at 12W), so each of the 1045's two USB ports (2.4A each, 12W) should be able to handle a comparable load.
Good catch; thanks!

You can damage a device with too high a charge rate though no? Maybe that only applies to over voltage and not amps? I see the 1045 on Amazon for $34.29. Maybe a better route if your doing more than just recharging.

New devices monitor and regulate what they can take for a charge.

Here's the BlueSea Systems #1045 on amazon.com if anyone needs it. I ordered one last week and will install soon.

Holy crap! They don't give those away!
This one isn't quite as powerful. (Dual 3.1 amp)
