I notice a flurry of comments about recharging the original iPad. Most suggest using the recharger that came with the unit. Unfortunately, I cannot find that charger. Question: Would plugging the USB 2 plug that comes with the iPad into an USB 3 do the trick? USB 3 has greater powering capacity, but I don't know if that works with the iPad USB 2 cord. Thanks for any knowledgeable advice.
