An interesting (to me, anyway) thing happened last week. I went away for the weekend, and it was the first time is taken my iPad Mini away with me. Wanting to travel light, I took both USB cables (for the iPad and the iPhone) but just the mains charger plug for the iPad. Turns out, it's geared to a waaay lower ampage than the iPhone one. When I plugged my phone into it, I assumed something was broken - the ampage is so low that the phone doesn't register as being plugged in at all. It did charge, but took about 9 hours to get up to 100%.

I'd noticed the iPad takes longer to charge than the phone does, but then the batteries are bigger, so I didn't think much about it until now. In future, I'll have to remember to take both plugs (and remember which is which, since I have no idea what might happen if I plugged the iPad into the iPhone charger).
If it's brokenless, don't suffix it...
