USB-C cables that do 240W charging and 40Gbps data at the same time (2026)
Updated 2026-11-08
Short answer. Buy the UGREEN Thunderbolt 5 cable ($45.99; buy: https://dealectric.com/go/ugreen-thunderbolt-5-cable-80gbps-240w), the USB-C cable that does 240W charging and 40Gbps data at the same time, and more: 80Gbps Thunderbolt 5, 240 W USB PD 3.1, 1 m, $31.99 on 2026-11-03 against $45.99, backward compatible with USB4 and Thunderbolt 4 at 40Gbps. Any cable rated 240 W must be e-marked for 50 V 5 A, and any passive 40Gbps or 80Gbps cable is 1 m or shorter; longer cables are active and most of those do not carry 240 W.
Cheaper and certified: UGREEN's own USB4 240W 1 m cable is $14.99 (e-marked, rated 40Gbps and 8K60 by retailers, sold out on 2026-11-03), Amazon Basics' USB4 240W 1 m about $14 (USB-IF certified per its listing), StarTech's USB-IF-certified USB4 1 m $23–29, Plugable's Thunderbolt-and-USB-IF-certified TBT4-240W-1M $34.95. UGREEN calls its Thunderbolt 5 cable Intel-certified; that could not be checked in Intel's or USB-IF's lists on the day, so buyers who need the certificate on paper should pick Plugable, Belkin ($53.99) or OWC ($34.99).

Rows marked with a code and buy link are products Dealectric lists: the price was verified on the brand's own US store on 2026-11-07 and the code is tested daily in that brand's cart; the date shown is its last pass (last check 2026-11-13). The other rows (Amazon Basics, Anker, Apple, Belkin, Monoprice, OWC, Plugable, StarTech, UGREEN) are included so the comparison is complete; their figures and prices were read from the makers' own US pages on 2026-11-03 and are not re-checked daily. The buy links are affiliate links: they open the brand's official US store at no cost to the shopper, and the commission pays for the testing; see the disclosure.
The rules behind the ratings
- 240 W is USB PD 3.1 Extended Power Range: 48 V at 5 A. The cable must carry an e-marker chip that declares 50 V 5 A; without it, a charger negotiates 100 W (20 V 5 A) at most. The laptop and the charger must both support EPR too; most laptops take 100 W or 140 W.
- 40Gbps passive USB4 and Thunderbolt 4 cables are 1 m or shorter (vendors quote 40Gbps at 1 m, 20Gbps at 2 m); longer runs need active cables, which cost $60–80 and are not all rated for 240 W.
- Thunderbolt 5 uses passive cables up to 1 m for 80Gbps (120 Gb/s one way for displays), per Intel's 2023 announcement, and is backward compatible with Thunderbolt 4, 3 and USB4 at their own speeds. A Thunderbolt 5 cable is therefore the one cable that covers every USB-C need below it.
- Certified versus rated. Intel certifies Thunderbolt cables and USB-IF certifies USB4 cables; both keep public product lists. A "rated" cable may work the same, but only a certified one has been tested against the spec by a third party.
Which to buy
For a Thunderbolt 5 Mac or PC and a dock, SSD or 240 W charger: the UGREEN Thunderbolt 5 cable at $31.99, or OWC's certified one at $34.99. For 40Gbps and 240 W on a budget: Amazon Basics or UGREEN's USB4 cable at about $14–15. For a cable that must show a certificate: Plugable, Belkin, Monoprice or StarTech.
