It does exactly what it is designed to do, charge AA & AAA batteries. The car charger is a neat feature but I'm not sure when I'll ever HAVE to recharge while driving. I'd check at your local Walmart or Walgreens first to see if they don't have a better value charger. After purchasing this I saw a 15 dollar name-brand energizer charger that does about the same thing, but didn't include a car charger or batteries. Overall though I am very satisfied with the product.
Very easy to use.
Instructions are not the best: The English is weird and the chart showing what the LED indicators mean had the colors reversed and did not agree with the narrative. There isn't any instruction on how to charge the AAA size batteries (though a focused inspection of the unit readily revealed how to do this - just flip down the little upper bar and it shortens the battery bay.)
Nice compact device and quick charge time.
I have not used the car power cord yet, but it looks quite handy.
The price of the entire thing (15.99) isn't much more than just getting the batteries at my local Home Depot.
Quick Charging and easy to carry. Worth buying as 4 AA & 4 AAA batteries are including with nominal shipping. Plus it works with universal voltage ( 110/240 V )which I feel the best thing in this. Only problem I found was charging instructions. Instructions and real charging were not in synch.. apart from that everything is fine.
