SKU CH-JEGT-YQ7MW

A 90-degree angled adapter converts a 4.5x3.0mm DC input into USB-C power delivery up to 140W for laptops, tablets and phones

  • 90° angled plug fits tight spaces around DC ports
  • Delivers up to 140 W via USB-C PD for laptops and phones
  • Accepts 18–20 V DC input from high-power chargers
  • Built-in 20 V 7 A PD trigger enables maximum output
  • Compatible with 65 W, 100 W and 135 W charging profiles

Angled DC-to-USB-C adapter

This adapter converts a 4.5x3.0 mm DC barrel input into a USB-C output capable of 140 W maximum power. It targets users who need to power laptops, tablets or phones from an existing 18 V to 20 V DC source in tight spaces. The 90-degree angle allows connection where straight plugs cannot fit. Compatibility requires the source to deliver 18 V to 20 V at up to 140 W.

Sustained 140 W delivery with PD emulation

A built-in PD emulator trigger negotiates the full 20 V 7 A profile so the adapter can maintain its 140 W ceiling during continuous loads rather than throttling after a short burst. Supported output steps include 5 V 2 A, 9 V 3 A, 15 V 2 A, 20 V 3.25 A, 20 V 5 A and 20 V 7 A. The unit also handles QC 2.0, QC 3.0 and USB PD protocols for broader device negotiation.

4.5x3.0 mm barrel constraint decides fit

The adapter only works with power supplies that use the 4.5 mm outer by 3.0 mm inner barrel connector and supply 18 V to 20 V DC. Buyers whose chargers have a different barrel size, a centre-positive tip of another diameter or a voltage outside the 18 V to 20 V range cannot use this unit. Verify the charger’s plug and voltage before purchase.

Questions about this item

Does the 140 W adapter get hot when it runs all day at full load?

The unit passes through up to 140 W from an 18 V – 20 V DC source; heat depends on the source charger and cable quality, not on the adapter itself.

What charger must I already own for this 4.5 × 3.0 mm angled plug to deliver 140 W?

You need a 135 W or 140 W DC charger that supplies 18 V – 20 V at up to 7 A with a matching 4.5 × 3.0 mm barrel tip.

Will this 90° DC-to-USB-C adapter negotiate 100 W or 65 W with my older MacBook or laptop?

Yes, the built-in PD trigger supports 5 V/2 A, 9 V/3 A, 15 V/2 A, 20 V/3.25 A, 20 V/5 A and 20 V/7 A profiles, so 100 W and 65 W devices charge normally.
