What's In The Box

OntheGo™ 67W Slim Wall Charger, User Manual.

Product Overview

The OntheGo™ 67W Slim Wall Charger puts 67W of USB-C Power Delivery into a body small enough to forget in a bag. Gallium Nitride circuitry keeps it compact, the AC prongs fold flat so nothing snags while you travel, and two USB-C ports let you charge a laptop and a phone at the same time. A single device on one port gets the full 67W, which is enough to bring an iPhone 16 to roughly 58 percent in 30 minutes.

Setup

1. Plug the wall charger into a US power outlet: Rotate the AC prongs outward, then plug the charger into a compatible outlet.
2. Insert a USB-C cable into the charger: Connect it to your USB-C compatible device or peripheral to charge. USB-C cables are not included.

Note: Charging starts automatically once the cable is connected at both ends.

Functions

Parts labeled diagram of the OntheGo™ 67W Slim Wall Charger with 2 labeled components.

1. Foldable Plug: The AC prongs fold flat against the body for travel. Rotate them out before plugging the charger into an outlet.
2. 2 x USB-C Ports: Two USB-C Power Delivery ports, marked 20W/67W and 45W/67W on the charger. Either port on its own delivers up to 67W. With both ports in use, the 45W/67W port delivers up to 45W and the 20W/67W port delivers up to 20W. USB-C cables are not included.

Features

- 67W of USB-C Power Delivery from a charger that fits in a pocket
- Two USB-C PD ports for charging two devices at once
- Gallium Nitride (GaN) circuitry for more power in a smaller body
- Programmable Power Supply (PPS) support for intelligent power delivery
- Foldable AC prongs that pack flat and do not snag in a bag
- Soft-touch, eco-friendly casing
- Over-current, over-voltage, temperature, and over-charging protection

Important Limitations

The two ports share the 67W total: Either port alone delivers up to 67W. As soon as you plug in a second device the output splits to 45W and 20W. For the fastest possible charge on one device, use a single port on its own.

USB-C cables are not included: The charger ships with a user manual only. You need your own USB-C cable, and it should be rated for USB-C Power Delivery for your device to reach its fastest supported speed.

Use the original device cable or a certified alternative: For optimal speed and safety, charge with the cable that came with your device or a certified replacement.

Warmth during charging is normal: The charger gets warm under load. Do not cover it or block airflow around it while it is in use.

Keep away from water, liquid, and moisture: For indoor use only. Do not expose the charger to damp conditions.

Do not disassemble or modify the charger: Keep it out of reach of children and do not attempt to open the housing.
