I make a habit of recharging as part of after run maintenance as well. In the past I have gotten lazy and not charged. In a case like this its great to be able to be up and running in 30-45 minutes.
Have you ever forgot to unplug your overnight charger? You don't have to answer because we all know the answer to that one. There is no question that an overnight charger works but for me it boils down to how well, how long, and convenience.
The unit I have saved me money, time, and space. I have 1 charger for all my Nitro needs. RX charger, TX charger, and glow stick charger.
Another added convenience is being able to charge in the field. This comes in handy for those long weekend camping trips. Just another little ditty to think about before purchasing a charger.
