Review on SDS Plus PWRCore Lithium Battery Charger by David Plunkett

Overall build quality seems good for the low price (3 stars generous). However this is one of the SDS Plus rock drill bits with a minimum output of 18v/20v but may be acceptable for light duty. The manufacturer's quoted rating is 7/16" in concrete, the smallest number I've seen for an 18/20v system. It has a suitably low impact force rating (0.7 ft-lb). only "hammer" (chisel), while almost every other rotary hammer has this function. On the plus side, it supports hex bits as well as SDS-Plus. power (1.3 ft-lb), being able to use as a chisel only in hammer mode, and also because I already have several other brand 18v batteries. So, even considering the lower price, I think it's better to spend a little more for a more powerful tool.
