Can't give you the measured speeds to compare, as they'd need to cover a range of batteries (2.0, 2.5, 3.0 & 4.0 Amp/hour) sizes of varying ages used on 3 tools, but at a rough guess they do the job in about a quarter the time required by my OEM chargers. If I'd had this charger sooner I'd have bought fewer batteries. If it fails soon or ruins batteries I'll update this review. For now I'd give it 6 stars.
