while I sorta agree with the sentiment, you can't really use Kakashi as a yardstick for chakra, seeing as he's always been shown to be a bit weak in that regard.
It might be a bit overblown here, but I don't find it too difficult to believe that Konohamaru is like Jiraiya or A.? One of those natural chakra powerhouses.
Kakashi may have not much Chakra, but he's still a 26 years old adult J?nin, while Konohamaru is a 13 years old rookie genin.
I mean, having enough chakra to use Katon G?kaky? no Jutsu is already impressive, having enough chakra to use a lot of Kage Bunshin AND rasengans at the same time withOUT a chakra entity in your guts is... well, overpowered.
Remember, Konohamaru didn't train seriously until he met Naruto 3 years before this... Sasuke has shown less growth
