Parts and Functions

Labeled diagram of the ChargeView™ 140W Desktop Charger showing four USB-C ports (1), digital display (2), display button (3), and desktop stand (4).

The seven primary components of the ChargeView™ 140W Desktop Charger are:

1. 4 × USB-C Ports — Four USB-C ports for simultaneous device charging. Port C1 supports PD 3.2 AVS at up to 140W. Port C2 supports PD 3.1 PPS at up to 100W. Ports C3 and C4 support PD 3.1 PPS at up to 40W each.

2. Digital Display — Front-facing screen that shows total wattage output in real time and displays thermal status using color-coded indicators.

3. Display Button — Press and hold for 1 second to toggle the display between horizontal and vertical orientation. After 1 minute of inactivity the screen automatically turns off and enters sleep mode.

4. Desktop Stand — Base that allows the charger to sit horizontally (flat) or stand vertically (upright) on your desk.

5. C7 Power Port — The AC inlet on the rear of the charger that accepts the included C7 power cord.

6. C7 Power Cord (included) — The AC power cable included in the box. Always use the included cord for optimal performance.

7. 4 × Silicone Dots — Four adhesive silicone feet that attach to the underside of the charger to prevent stand interference and keep the unit stable on your desk.

Setup

Step 1 — Attach the silicone dots

Placement guide for the four silicone dots on the underside of the ChargeView™ 140W Desktop Charger.

Before using the charger on a desk, attach all four silicone dots to the underside exactly as shown in the diagram. Correct placement prevents rocking against the stand and ensures stability during use.

Step 2 — Connect the power cord

Plug the included C7 power cord into the C7 power port on the rear of the charger, then connect the other end to a standard AC wall outlet (100–240V ~ 50/60Hz).

Step 3 — Connect your devices

Connect USB-C cables from your devices into any of the four ports. The digital display activates and shows total output wattage. Each port's indicator on the display turns green when that port is actively delivering power.

Power Distribution

The ChargeView™ 140W Desktop Charger dynamically allocates power across all active ports. Total output never exceeds 140W regardless of how many ports are in use.

Digital Display Guide

The front-facing digital display on the ChargeView™ 140W Desktop Charger shows real-time wattage and thermal status.

Switching display orientation: Press and hold the display button for 1 second to toggle between horizontal and vertical screen orientation. Set it to match how the charger is positioned on your desk.

Auto-sleep: After 1 minute of inactivity the display turns off automatically. It reactivates as soon as charging resumes.

Port activity indicators: Each port has an individual indicator that lights green when that port is actively delivering power. The C1 port's AVS indicator lights green for 5 seconds each time a compatible device begins drawing AVS-mode power.

Temperature monitoring: The display uses color-coded states — Blue (Excellent), Green (Optimized), Orange (Cooling) — to indicate the charger's current thermal condition.

Advanced Charging Technologies

PD 3.2 AVS — Adjustable Voltage Supply (C1)

Port C1 supports USB Power Delivery 3.2 with AVS (Adjustable Voltage Supply). AVS dynamically fine-tunes voltage in real time, enabling compatible devices such as the latest iPhone models to charge faster and more efficiently while operating at lower temperatures. Single-port maximum: 140W.

PPS — Programmable Power Supply (C2–C4)

Ports C2 through C4 support PPS (Programmable Power Supply) as part of the USB Power Delivery standard. PPS dynamically adjusts voltage and current in small increments for efficient fast charging on compatible Android smartphones, including Samsung Super Fast Charging and Google Pixel fast charging.

Important Safety Notes

Always use the included C7 power cord for optimal performance. Do not substitute with third-party cables. Keep the charger away from water or other liquids. Do not cover ventilation areas while the charger is in use. If the charger is damaged, stop using it immediately and contact Satechi support at support@satechi.com.
