MOTOPOWER MP0514A 12V Digital Car Battery Tester Voltmeter and Charging System Analyzer with LCD Display and LED Indication - Black Rubber Paint

This thing is a lifesaver! I bought this because I was having starting issues with my 6.0 turbo diesel Ford F250. This has two batteries and the truck came with the undersize alternator stock. I was having to call AAA all the time. Bought this thingand the truck starts right up. Don’t even need to jump 2nd Battery. It’s worth the $ to buy NOCO brand is the only way to go but make sure you buy the right size. Diesels need the bigger models. This is barely big enough for my 6.0 but they have the 12v car charger but take a bit to charge back up.

This product gives an accurate reading of battery level. It has a nice bright screen. It’s very small and compact. I like the overall design. I would recommend this product.

It's good for price and work great but very small it fits in your shirt pocket

Love it! It give me piece of mind that the battery is still good and alternator is still in good condition. You can save money knowing all of these before talking to people at the shop which usually takes advantage of women.

This is a great little investment it's as described and works well

Outstanding piece of equipment. I saved me from going to a dealers agency and spend $1,000

Worked as advertised..LCD voltage meter have correct output..don't rely on descriptive lights

It doesn't do much that a simple voltmeter can't do. If you know nothing about cars and charging system, then it might help a little. But don't trust it, get a better test for free at most auto parts stores. For the price, it is what it is.
