    any of you guys use one of these and how’d it work out for you? Figure it would be a cheap easy way to keep an eye on things. Junk or no ?

    I just picked this brand at random.

    I have one that I use for my daily drivers. Great to check voltage quickly to verify battery or charging system.

    I have one in all my cars. A great way to keep an eye on battery and charging operation. Also shows charging current being consumed by your phone, once you connect it. For that $12 price, it should be better quality. The cheap ones I use are about $6-$7, and they're still fine. Order a handful, you'll be giving them away to your friends and family.

    I have one for each old car and for both pick ups. They work great. I used mine in the Swinger a hour ago.

    They read voltage then turn to amperage draw when you plug your phone in.

    One thing to note, of course they are measuring voltage where they are plugged in... So if it reads lower than you expect it's possible it's voltage drop across old wires and nasty connections and not a bad alt or regulator.

    This.

    The lighter is also a perfect place to monitor voltage since it isn’t a switched voltage source and is constantly hot. Has easily and quickly let me know many times when my battery is dead, or to turn off my accessories before my battery dies.
