Great replacement
Needed a replacement charger for my drill after the seller refused to send me a new one under warranty. This one works great. Even has a little light to let you know when it's charged

Make sure you check all your options
My fault but this item did not fit my need. It was wider and useless for me. Eventually I managed to find one that had an optional pin plug that this did not.

Works and charges 21v batteries at 2 amps, more power faster charging.
The led light indicator red light means charging, green means fully charged. The red led is very dim, my only complaint. It charges much faster than the 1 amp factory chargers. Good charger. It Fully charges 21v Makita style Chinese batteries for lower priced Chinese tools.
