LIHAN 3 USB Car Charger,12V/24V Voltage Meter, QC3.0 Output 4.8A, Cigarette Lighter Plug Adapter Compatible with iPhone,iPad, Samsung, USB Charging Devices, Silver

This is a triple USB outlet that plugs into the usual cigarette lighter socket of a vehicle. The first thing I noticed is that the spring in the base is very strong. The unit required a good amount of force to push it into the socket all the way. This is good for my purposes because I am using it in a 4WD vehicle that gets a lot of hard bumps that could dislodge a weaker spring. If one is going to constantly insert and remove this unit, the amount of force may eventually damage the outlet.Much left unsaid in the description of this unit, so I researched the amperages of several devices that I will be using in my vehicle. I will fill in the blanks in the advertising.First, the green outlet labeled QC 3.0 means that the maximum amperage output at this port is 3.0 amps. The unit is rated at 36 watts which means that at 12 volts, all the power would be going to this port for a device drawing 36 watts. Luckily, most iphones use 20 watts so there will be 16 watts left for the other 2 ports.Not mentioned are the amperages of the other two ports. For USB 2.0 the maximum is 0.5 amp and for USB 3.0 it is 0.9 amps. This comes out to 6 watts and 11 watts. If one is trying to use two iphones, the one on the 3.0 port will stay charged but the one on the other port will not. One must be careful about how many devices are being used on this unit.All in all it is ideal for my purposes which are to use a GPS, a hand held GMRS radio and a cell phone. All together those do not exceed 36 amps.A nice feature is that the detected volts in the cigarette socket is displayed in blue on the unit. The reading I get is 12.8 V which is probably accurate. This may give one warning if the battery in the vehicle is getting weak, which is any voltage less than 12 V.

Why did you pick this product vs others?:This fits tightly in the auxiliary power outlet and doesn't loose electrical connection.

Works very well. I like the digital display.

It works as stated…just don’t expect CarPlay to work when u plug ur phone into this.

Nice product. Good quality. Works as advertised and provides a snug fit in the cigarette lighter socket. There a million of these kind of gadgets in the marketplace. This happens to be one of the better ones. Purchased another one recently.

I am very impressed with the LIHAN Dual USB Car Charger! This compact little charger is incredibly efficient and easy to use. It fits snugly into my car’s cigarette lighter and allows me to charge two devices simultaneously, which is a huge bonus. The 4.8A output provides fast charging for both of my devices, which is perfect when I’m on the go.One of the standout features for me is the voltage meter on the charger. It’s so convenient to be able to monitor my car's battery health while driving. The LED display is easy to read and not overly bright, making it perfect for nighttime driving. If the voltage ever goes out of range, the flashing light alerts me to a potential issue, which gives me peace of mind when I’m on the road.The build is slim and lightweight, which is great for portability and doesn’t get in the way while charging. I love that the charger protects against overheating, overcharging, and short circuits—it really feels like a well-designed, reliable product. I’ve used it with both my iPhone and iPad, and they charge quickly with no issues.Overall, this is an amazing, practical car charger that does everything I need. I highly recommend it for anyone who needs a reliable, fast-charging solution with added functionality to monitor your car's battery voltage!

Nice , works great

Nice looking in my 1967 car that I wanted USBs and voltage displayed. Killed 2 birds with on stone, no wiring
