This is a really good smart charger for being the cheapest one on the site. It charged my 8.4v 1600mah battery in 3-4 hours compared to like 8 on a normal charger. Like some of the other people said, it does not have the stuff to hook it up to a car. I have used it a couple tmes now and have had no problems. I was worried about geting it at first because I didn't recognize the company but it is great. One warning, do not choose the 600mah charging option, always keep it on 300 atleast for an 8.4v. I left it on for a couple hours on 600 and when I came back my battery was very hot. It is perfactly fine, but I reccomend the 300mah setting. It still charges really fast and the battery never gets hot. Even though you can't really see it in the picture, it has a light that tells when it is charging, done charging, or discharging. Also, this thing is pretty big, I thought it was like the size of a normal charger, but it is like the size of 3 of them put together. One more thing, like the other people said, ignore the chart on the back, just choose 300mah and the number of cells your battery has.
Charges really fast
Can charge small and large type
Can discharge NiCad's
Tells you when it is done
600mah setting could kill some batteries
You don't have it yet!
