This Aerb USB Car Charger’s selling point is the LED display and the two charging ports. It not only charges our devices, it also tells us the cabin temperature, the car battery level, and the amperage.
For charging devices, it’s a winner. I’ve used it all over town, all out of town, just about everywhere. Every time the car is on, the car charger is, also – powering my dash cam, charging my devices.
The battery level always measures above 11 volts, and well it should. Otherwise I’d need a jumpstart.
The thermometer only measures in Celsius, not Fahrenheit, so it’s less useful for those in the States. I tested it against a thermometer known to be accurate, and it’s about one degree Celsius higher than it should be.
One of the ports is 2.1 amps and the other is 1 amp, but that’s not marked anywhere. I’m not sure which is which. The amp meter doesn’t help, because it’s not accurate. Sometimes, it reads 0.00 amps when charging a device. Not possible. Alternatively, it may read above 1 amp when charging my phone. The phone never charges above 1 amp, and I checked the amperage with an amp meter connected to the car charger to verify.
So yes, this works. The temperature is not off by much and car battery monitor seems about right. The problems are the amp meter and labeling the ports. Minus one star for those issues. Most of us just plug and charge and that’s all that matters.
