According to my father, this device performs better than expected as a cheaper model. (I don't know much about this product so I'll just take his word for it!) It works great. I also like the case it comes in. I tested it with batteries and a phone charger while plugged into the wall. You can check your phone chargers to see how much power they put out. You can also use it to test a car battery. You can also test all your batteries. This type of counter comes in handy when you least expect it!
