Pure Copper USB C Car Charger, 45W Dual Port Fast Charger | 27W USB-C PD and QC 3.0 fast charging with LED voltage display, Charges two devices at once and fits iPhone, Samsung, Pixel

Good heavy duty product.

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.

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

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.

Who smokes anymore? Put that 12V port to much better use, I did! This little gem works great in order to monitor my voltage and give me access in an older car to two usb charging cables!

Love that I can see our car battery’s voltage. Don’t have any fancy meters to measure the accuracy of the product’s claim for voltage and amps but this charger works fast and faster than our Apple 20w charging block. Good to have for a quick charge or when using battery consuming GPS apps on your phone. Still has the old USB A port for classic legacy devices if needed. I just keep an adapter if I need it for USB C devices. Charger stays fairly warm, not hot when both ports are used as expected. As long as it’s not running hot, it’s ok. The metal body dissipates heat quickly and won’t melt like the plastic ones. Highly recommended.

It’s good quality but the blue LEDs are blurry.

Works perfectly and it’s nice to see the battery voltage
