myVolts Dell 7.4mm to 4.5mm Power Tip 2 Pack

SKU CH-THC5-7N0DN

Two-pack adapter converts Dell 7.4mm charger tips to 4.5mm for XPS, Latitude and other models

  • Converts 7.4mm Dell chargers to fit 4.5mm XPS ports
  • Works with Latitude 7350 and XPS 13 9350 models
  • Replaces Dell part numbers D5G6M and 57J49
  • Built-in chip protects against leakage and short circuits
  • Lightweight 30g design extends life of existing 90W adapters

Connector conversion for Dell systems

This adapter converts any Dell laptop charger with a 7.4mm x 5.0mm connector to the 4.5mm x 3.0mm type required by many ultra-slim XPS models. It replaces part numbers D5G6M and 57J49 and works with Latitude, Vostro, Precision, Studio and Alienware lines. The pack contains two tips so you can keep one at a desk and one in a bag. Buyers who need a different barrel size or a USB-C output will not be served by this product.

Thermals and power handling

The dongle uses an original chip to provide smooth current transmission with leakage and short-circuit protection, allowing safe charging at the adapter's rated output. Its lightweight construction adds negligible bulk to the cable and does not introduce audible noise or measurable heat during normal use. No active cooling or fan is present. Builders who require a higher wattage rating than the source adapter provides cannot increase it with this tip.

Sustained-load behaviour

Under continuous load the internal chip maintains stable voltage delivery without overheating, letting the host laptop draw its full design power from a compatible 90 W Dell supply. The short-circuit protection remains active throughout extended sessions, preventing damage if the connector is accidentally shorted. Users who expect the tip to negotiate higher voltages or support power-delivery profiles beyond the original charger's capability will find it does not do so.

Questions about this item

How do I fit the 7.4mm to 4.5mm tip onto my Dell charger?

Slide the 4.5mm end onto the laptop DC jack and the 7.4mm end onto the adapter plug until both click; the step people miss is seating the larger barrel fully so the inner pin makes contact.

Will the tip or its internal chip wear out and need replacing?

The dongle has no moving parts or battery; only physical damage to the 4.5x3.0mm or 7.4x5.0mm connectors would require a new tip.

What is the first limit I hit when using this tip continuously on a 90W adapter?

The tip is rated for the adapter's 90W output; sustained loads at that level are limited by the adapter's own thermal protection, not the dongle.
