This seems similar to the one above but with a car adapter included and it looks like it feeds more current to the cells which will mean faster charging. It even has the same refresh function.
Update: I bought one.
That one will only charge two AAA cells. It actually charges at a slightly
lower rate than the "Sony." Comparing the two chargers and the label on the back of one, I would say that both chargers will charge a single AA cell at 2 amps. The more I compare these two, I keep thinking, "too bad the slightly more expensive one only charges two AAA cells instead of four like the other one", because it does have an advantage in that it is the only one that will run off of included 12v plug.
Does somebody know what the discharge rate is on refresh?
Wondering if, say, four AA cells are placed on charge at 525 mA, as they terminate one by one does the charge current go up on the remaining cells to 1050 mA, and then 2 A on the last cell? From the way the charge current is dependent on the number of cells, it may appear so.
But like someone said already, if you can and
want to spend $40, go for the La Crosse BC-900. It is much more versatile and informative than these chargers, and leaves no questions what each cell is doing exactly.
