[Pure Copper] USB C Car Charger, SUPERONE 45W Dual USB Car Charger Adapter with 27W/20W PD Port, Fast QC3.0 LED Voltmeter for iPhone 17 16 15 14 Max/Pro/Plus/Mini, Pixel 9/8/7, Samsung S25/S24 More

Very happy with this power supply. My car has a manual transmission with a vertically mounted outlet between the center console cupholders and the stick. Most normal power supplies have a higher profile that make it easy to catch when shifting, but the low profile of this is perfect. Looks great and it's also nice having the voltage displayed right there. The display is clear even in bright daylight, and the whole thing feels substantially constructed. Very highly recommend.

Meter works as it should and is accurate and stable, checked it with a high accuracy DVM. The charging ports are handy for those of us with an older vehicle with no charging ports. I don't know what this Solid Copper business is all about though...It has a chrome look electro-vacuum deposited plastic body

It looks even better than it does in the pictures, and works great! Fast charging, nifty voltage display, and the copper body does a great job of dissipating the heat.

I ordered 2 of these. The build quality seems solid, not cheap plastic like some others. One of the units read .5 volts higher than the other. I confirmed that one of them was in fact accurate, and one was not. I returned the inaccurate one for an exchange and am happy to say the replacement one is also accurate. 1/2 of a volt error is substantial when comparing the difference between (12.2 volts =60%) and (12.7 volts = 100%). I would recommend this device as it has great build quality. I would however suggest you confirm accuracy on the item you receive.

Anyone with an older European car knows the pain of trying to use modern 12-Volt adapters. They typically do not fit well or fall out when driving. This fits my 1971 Porsche 911 perfectly and allows me to see real-time changes to voltage across a variety of engine speeds and accessory usage. Easy to read digital display that is bright enough in sunlight but not distracting at night.

Great product! The high output c2c charger is great! The USB is good too just not as powerful. Love the voltage reading... Not 100% accurate but close enough to gauge how your electrical system is doing.

Works like a charm

Great low profile charger. The voltage meter allows you to monitor the health of your battery and alternator. Lookup the voltage for your vehicle when running and off. Monitor changes by the display from inside your cabin. Has held up. Recommended buy.
