Great voltage meter

Hands down an easy addition to my system and it reads the volts accurately while charging my phone

Stinger volt meter

I love it I can keep track of my volts better

Easy to use

Just a plug in and it’s good to go it’s so nice cause it don’t ratte out or anything

Useful tool

I think this works pretty well if you're just wanting to get a general idea of where your voltage is sitting. I wish it was a little shorter

Awsome

This thing is everything you’d expect from my plug and play voltmeter it has been absolutely fantastic since the day that I bought it it never lets me down and it shows up bright blue so I can see it even during the day time

Couldn’t be better

Much easier than wiring it to Your amp. If you need a voltage meter and need one quick or don’t have time to install one this is a great option and easy to use, plus you can plug in your phone too

Cute

It looks good nice display. Good for keeping an eye on battery voltage when running the system with the car off. Reads a little higher than another meter I am running but they are on different feeds. Reassuring to see over 12v or over when running the system with everything on.

plug and play

I really like the fact i can just plug this stinger SGP12 into my lighter and it monitors the current voltage continuously, not to mention i still have a charging port nice work Stinger

Great product, low price, accurate.

Shows readings that are consistent with my multimeter. Has charging port. blue backlight. A little long for my application. It extends about 3 1/2 inches out from power source, which would be great for SUVs and trucks that have low cigarette lighter, but for my car, I wish I could've chose a more-flush-design.

Good product, awesome deal!

The last voltmeter I had actually gone on top of my battery. It made it really hard to see the voltage fluctuation while driving lol.

But this can be plugged into any outlet and lucky for me I have one directly under my Double Din! I would’ve bought it even if it didn’t have an extra USB charging outlet!
