AINOPE Car Charger Adapter, Dual QC3.0 Port 6A/36W Fast USB Car Charger All Metal Cigarette Lighter USB Charger Voltage Display Compatible with 11/11 pro/XR/X/XS/8, Galaxy Note 8/S9/S10+/S8-Black

I ordered this charger/voltmeter to replace a very similar product with a display that has dimmed over time and is difficult to read during the day by just glancing down at it. This product is dimmer than the one it replaced and during the day it is very difficult to read unless I stare at it, something not conducive to safe driving. It is not even close to being as bright as the pictures on the Amazon page. It appears to perform properly but being almost unreadable negates its main function to me, ergo one star.

I use this as a USB charger on my motorcycle. It charges fast enough that I can use my iPhone 11 for maps and navigation all day and still be fully charged. Had to add electrical tape below the fat top to keep it from vibrating out of the 12-volt socket. Shows system voltage too; alternates between showing system voltage and charge output when a device is plugged in. Simple add for my bike and very useful.

Dead on arrival. Plugged in, no charge, no LED display, no anything.

Works as advertised. Fast charges my phone and shows an accurate voltage reading.

I like this plug-in volt-meters simplicity and the ability to charge mobile devices via the USB ports. I bought this version because the amber display matches the other elements on the dashboard of my car. Because the outlets go dead when the vehicle is off, I still have to occasionally check the battery with a meter under the hood.

I bought this in order to charge two phones at the same time as well as tell me what my battery voltage is while my vehicle is off. When I first plugged it in, it Immediately powered on and displayed the correct voltage. However, as soon as I plugged my phone into it everything went haywire. It started flashing numbers all the way from 0 to 90 Volts. Looking at my phone, the lightning bolt charge icon was flashing on and off. I love the idea of this little handy tool, but it just doesn’t work straight out of the box. Maybe I got a dud. Update: A replacement was sent and functions as it should. It still shows random numbers, But I believe they are what the current draw is on the battery. I have no idea because there was no instructions that came with it. That’s the reason for four and not five stars. It still serves it’s purpose as a dual USB charger that charges very quickly.

Stays in place. Love how it monitors your battery voltage.

I like the voltmeter that tells me the battery voltage. It seems to be accurate based on my ODB2 monitor. The USB sockets are tight and make good contact. Unit fits within the cigar lighter space. The cigar lighter connector fits tightly and snuggly into the lighter socket. It’s a real good unit.

As soon as I got it out of the package and plugged it in, it did not work. I have a $20 paperweight that the seller says I cannot return or get a replacement. DO NOT BUY!!!!!!!!!!!
