I'm looking to get a multi port usb charger to chare multiple items (iPhone 6, Apple Watch, iPad Pro, and the occasional flashlight.... not made by apple!). I've read that the iPad Pro needs 28w but I'm usure about the ideal amps. Some mulitport charges have specific amp ratings per port. Some have "smart port"... I just want a charge to charge them all. I'm looking at this one: http://www.amazon.com/RAVPower-Char...s=usb+charger+50w&refinements=p_85:2470955011 And this one: http://www.amazon.com/Aukey-Charger...s=usb+charger+50w&refinements=p_85:2470955011 Does anyone have a good recommendation?
