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

Sturdy heavy works great. And display has the right brightness. Very satisfied

Works perfectly with both mine and my husband’s phones in the truck. I like the dual ports and it charges very quickly. Very heavy duty too.

I installed this product in the center console cigarette lighter to use as both a voltage monitor and a USB access point for iPhones and android phones. The device feels really solid and has some weight to it which is nice it keeps it solidly in the cigarette lighter socket. Its really well made, feels very solid and the LED voltage indicator is a quick way to check on battery condition and your alternator charging. In fact I liked the device so much that Im going to order a spare one to give to someone else as a gift. Great product great Price Amazon prime!

Charger works well but voltage display only works while not using it to charge. Voltage display bounces up and down erratically when charging. That being said it charges well and does have an accurate voltage reading otherwise.

low profile design. very ergonomic and convenient for a quick charge. also viewing battery health

Started return. Piece of junk. what a waste of time. At least full refund, still wasted my time, now I have to drop off at UPS

Good to monitor vehicle voltage.

Wont stay plugged in reliably. Pops out at slightest touch or bump. Side contact springs NOT strong enough. Nothing worse than coming back and finding you phone still dead because this thing popped out. Bad engineering.

I purchased two of these devices which work well for the intended purpose. Customer service was great. I purchased a third adapter under a separate purchase. It is very useful to have the voltage displayed. Adapters appear to be of a good quality.

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.
