Review on 🚗 Dual USB Car Charger with 4.8A Output, Voltage Meter, Compatible with Apple iPhone, iPad, Samsung Galaxy, LG, Google Nexus, and USB Charging Devices - Black by Stephen Pendergrass

So far, so good. My main reason for purchasing this USB car charger with digital voltage and current display is to monitor the output voltage of my truck's alternator. It's fairly accurate by comparing the voltage readings to my Fluke DMM which I compared to a real Fluke. The device reads 0.1 volts less than my multimeter reads, which is close enough for me. I hope this article lasts a long time. I haven't used it as a USB charger yet, so I don't know how well it works. If I remember I'll edit my review to include info on how it works as a charger.
