Yes it does both buck and boost, so the output voltage can be higher than the input. It covers a variety of battery chemistries, I've also charged Lead Acids with them. And if you break old laptop batteries for the 18650 cells it has a discharge mode too, so once you've charged them you can discharge and measure the actual mAh rating of the cells.
I only mentioned the menu system because I recommended one to a friend who is not technical and he can't get his head around it for charging his marine radio.
The menus aren't too bad once you get your head around the settings. At the basic level you need to know the number of cells in series and battery chemistry - though it displays expected voltage IE "11.1V(3S)" for 3 cells in series. If you do something stupid it does check the cells being charged and will warn you if they're outside the expected voltage range when starting charging.
You can set limits, IE maximum charge time, or maximum capacity in mAh, so if a faulty battery never completes charging you don't just boil it dry/burst it. If you are using a lead acid as the power source, it also makes sure it doesn't drain it too far. It's a really smart bit of kit for the money.
