Ryobi Charger Upgrade: Worth It?

Amazon: http://amzn.to/2mQ5IJ4 Home Depot: https://homedepot.sjv.io/6Q5oq Is it worth upgrading to the "30 Minute" charger? Ryobi doesn't really list charge times for their P117 and P118 chargers, so I did some testing, and here's what I got: P102 battery on the P118 charger: 0:45 P102 battery on the P117 charger: 0:28 P108 battery on the P118 charger: 2:19 P108 battery on the P117 charger: 1:21 Times are listed in H:MM format, for completely empty to completely charged.
