USB C 140W Smart Charge Adapter with Power Display

You plug the phone in for the night and the little screen lights up with exactly what it is drawing.

This small metal adapter sits inline on your USB C cable, the charger going into one end and the phone into the other. A crisp digital screen reads out the live voltage, the current in amps and the charge that has passed in mAh, so you can watch the fast charge climb instead of guessing.

A smart chip watches the charge, and when the phone reads full it cuts the current so it stops drawing power overnight. It carries up to 140W of flash charge straight through, with built in guards against over current and overheating, and a button with a soft light ring on the front. Choose black, white or gray to match your desk.

Key Benefits

• Live power display A digital screen shows the voltage, the amps and the mAh passing through in real time as the phone charges.
• Cuts off at full A smart chip reads when the phone hits full and cuts the current, so it stops drawing power once charged.
• 140W flash charge Passes up to 140W of fast charge straight through so the adapter never slows your cable down.
• Built in safeguards Guards against over current and overheating are built into the chip for everyday peace of mind.
• Slim USB C inline A compact metal body that sits inline on a USB C cable and stays out of the way on the desk.

Best for: Anyone who wants to see what their fast charger is really delivering and stop the phone drawing power once it is full.

Why It Works

A plain cable tells you nothing and a bulky power meter is a lab tool, not a bedside gadget. This one puts a clear voltage, amp and mAh readout in a slim inline body, then adds a chip that cuts the current at full charge, so it earns its place on the nightstand as well as the desk.

Quick Product Facts: USB C inline charge adapter; digital LED display of voltage, current and mAh; smart chip that cuts current at full charge; up to 140W flash charge pass through; over current and overheating protection; button with light ring; black, white or gray.

How It Fits Your Routine

On the nightstand it charges the phone fast and then cuts the current once it reads full, so it is not pulling power through the small hours.

At the desk the live screen lets you check that a cable or charger is really hitting the fast speeds it promises, in volts, amps and mAh.

Slip it into a bag with your cable for travel, where the compact metal body and clear readout make it easy to keep an eye on a hotel or airport charge.

FAQ

How does it connect? It sits inline on a USB C cable, with the charger plugging into one end and the phone into the other, and the screen facing you.

What does the screen show? It reads the live voltage in volts, the current in amps and the charge passed in mAh, updating as the phone charges.

Does it really cut off at full? The smart chip cuts the current when the phone reports a full charge, so the phone stops drawing power until you unplug it.

How fast can it charge? It passes up to 140W of flash charge straight through, so a fast charger and cable keep their full speed.
