Not for standard charger. Off by 5 min +/- off. And let's keep in I did not sit there drinking coffee and watching it. Dewalt never less the 1/hr. Maki 45/min. Hilti 30+/- on standard and approximately 15/min faster in hilti 22v is dam Good. Recently did test in shop between Hilti and Maki impact drivers. With 70 - 5"*1/4" Simpson sds lag's Maki was getting pretty hot in handle and down to 2/bars on battery with 5.0amp. Hilti was just shy of full 4/bars and barly warm at bit tip area. Speed was dm close between the two. Not saying Maki is bad but would fail soon so impact wrench is absolutely needed to keep pumping. . Sent from my E6810 using Tapatalk
