Important Usage Notes

⚠️ Please read before ordering: This converter outputs power equal to what your existing DC adapter supplies. If your female (wall) adapter is rated at 45W (e.g. 19V/2.37A), the USB-C PD output will also be 45W — not 65W or 140W. Additionally, if your wall adapter is 12V, the Type-C output will support 5V, 9V, and 12V only — not 20V. We recommend using a 65W or higher-rated DC adapter for best performance.

Frequently Asked Questions

Q: Will this DC to USB-C adapter work with my HP or Dell laptop charger?

A: Yes — as long as your existing HP or Dell DC adapter uses one of the supported barrel connector sizes (such as 7.4×5.0mm for HP or 4.5×3.0mm for Dell) and outputs 15–20.5V, this converter will work. Please check your adapter's connector size and wattage before ordering.

Q: How much power can I get from this DC to Type-C converter?

A: The converter supports up to 140W maximum (20V @ 7A) via USB-C PD — but the actual output is limited by your existing wall adapter's wattage. For full 140W output, your DC adapter must be rated at 140W or higher. Using a 65W adapter will yield 65W USB-C PD output.

Q: Is this converter compatible with the Steam Deck or other gaming handhelds?

A: Yes! This adapter is compatible with the Steam Deck, as well as many other USB-C PD-enabled devices including tablets, laptops, and gaming handhelds from major brands. Ensure the USB-C device supports PD charging for optimal results.

Q: Does this converter come with a wall plug or just the cable adapter?

A: This product is a converter cable only — it does not include a wall adapter. You connect your existing DC barrel-plug laptop adapter (female end) to this converter, and the male USB-C end plugs into your device.
