I have many 20V tools, that this charger keeps up with, and 3 batteries to run them all, it works very well rotating the batteries. Best buy for me. Love it
[This review was collected as part of a promotion.] KKKKRRAAAAK! BA-ROOOOM!!! Working out in the garden, that caught my attention immediately! A branch had broken off one of my 100+ year old oaks. This particular branch was around 24 inches diameter at the base and over fifty feet long. All I had available for cutting this huge branch was my 10 inch WORX 20 volt chainsaw. After pulling the branch out of my neighbor's driveway, I used this little saw to remove all the limbs. While the saw worked great, the 2 AH battery was only good for about half an hour before it needed recharging; which took around 3 hours. There had to be a better way, so I got on-line to see about getting some heavier duty batteries. What I settled on was a four pack of 2AH batteries and the WORX 20V Power Share 1-hour Dual Port Quick Charger. The 20 volt batteries charge up to 21 volts and die at around 3 volts. A dead battery will fully charge within an hour in the 20V Power Share 1-hour Dual Port Quick Charger, and with the five batteries I now had, trading them out as they died, I was never without a charged battery to put on the saw when the one in use ran out of energy. While the little 10" saw was the hero of the story, it would have taken forever to cut up that huge branch without the 20V Power Share 1-hour Dual Port Quick Charger. How do you cut a 24 inch log with a 10 inch saw? Well, those pieces were hollow. But it did cut up to 21 inch sections by working it around the branch, since they are not perfect circles.
