78 W four-port car charger

This 78 W car charger supplies two USB-C and two USB-A ports from a single cigarette-lighter socket. It charges phones, tablets and compatible laptops simultaneously while displaying the vehicle battery voltage on an integrated LED voltmeter. The aluminium housing aids heat dissipation and a built-in smart chip manages power delivery. It suits drivers who need multiple fast-charging ports on the road.

Charging limits of the PD 3.0 PPS QC 3.0 protocols

The charger follows PD 3.0, PPS and QC 3.0 standards, so each port negotiates the highest voltage and current the connected device accepts. Maximum output is shared across all active ports, so total power drops when four devices draw simultaneously. Phones such as iPhone 17, 16, 15, 14, 13, 12 series can reach 80 % in 30 minutes, Galaxy S26, S25, S24 series 80 % in 35 minutes, and most Android phones 70 % in 35 minutes. iPad models reach 60 % in 30 minutes.

Upgrade from single-port or lower-wattage adapters

This unit replaces a single-port car charger or an older adapter that lacks USB-C Power Delivery. The jump is worthwhile when you regularly charge a laptop, tablet and two phones at once, or when you want the real-time voltage readout to monitor battery health. It is not for buyers who need more than four ports or a higher total wattage than 78 W.

Questions about this item

Should I pick this 78W four-port charger over a lower-wattage model?

Choose the 78W unit when you regularly charge a laptop such as a MacBook Air alongside phones; the total budget lets a USB-C port push high power while the other three ports share the remainder.

What does the 78W rating deliver to an iPhone 15 in daily use?

The charger can bring an iPhone 15 to roughly 80% in 30 minutes when the USB-C port negotiates the fast-charge profile.

Which charging standards do the USB-C ports actually support?

Both USB-C ports implement PD 3.0 and PPS, so they negotiate the optimal voltage for recent iPhones, iPads, Galaxy S-series handsets and compatible laptops.
