It depends on how serious you are about staying in the hobby and how adept you are at dealing with gadgets. If all you ever you plan on just casual flying with 1-2 basic planes then it may not be worth the investment. If you don't like dealing with setting up electronic devices and navigating menus & such then it's probably not the best idea either. If you intend to stay in the hobby though, you don't mind reading the charger manual, and you are going to buy a charger of some sort, I'd say go for it. You're likely going to invest in something like it at some point anyhow.

If you want to keep it simple though or have a dollar figure in mind, there are plenty of other viable options.
