USB-A or USB-C: what is the difference, and which should you choose?

Sarah from Titan Power Plus5 min read

The short answer

USB-C is the smaller, reversible plug with Power Delivery up to 240W, while USB-A inserts one way, so choose USB-C wherever your charger and device have the port1,2,3,4,5. A USB-A charger still works through a USB-A to USB-C cable, at Type-A-level performance in EcoFlow's guide6. Titan Smart Cable PRO supports up to 100W on USB-C PD7.

Key takeaways

  • USB-C Power Delivery reaches up to 240W in both EcoFlow's guide and Belkin's page5,8.
  • USB-A power figures differ by guide, from 4.5W in SC&T's guide9 to up to 15W with USB 3.0 or USB 3.1 in Anker's guide10.
  • A USB-A to USB-C cable gives Type-A-level performance, according to EcoFlow's guide6.
  • USB-C plugs in either way, while USB-A inserts in one orientation, according to EcoFlow's guide1,2.
  • Warranties on the cable sheet run from 12 months11 to 2 years12,13,14.

How much power does each connector carry?

USB-A power figures depend on which guide you read. SC&T's guide says USB-A generally supports a 4.5W charging capacity9. EcoFlow's guide says USB-A typically delivers 2.5W to 12W15. Anker's guide gives around 2.5W for USB 2.016 and up to 15W with USB 3.0 or USB 3.110. SC&T's guide also says Quick Charge QC 1.0 through QC 4+ can support up to 18.5W17.

USB-C power figures vary from guide to guide as well. Anker's guide says USB-C can deliver up to 100 watts of power with USB-PD18. EcoFlow's guide says USB Power Delivery can deliver up to 240W8. Belkin's page says USB-C can support Power Delivery up to 240W (48V/5A)5. The table “USB-A vs USB-C: what each guide states” sets these figures side by side, each with its source.

EcoFlow's guide says that with an adapter or a USB-A to USB-C cable you only get Type-A-level performance6. A USB-A to USB-C cable therefore charges at the USB-A figures above, not the Power Delivery figures, by EcoFlow's reading6.

How fast does each connector move data?

USB-A speed figures also differ between guides. VisionTek's guide says USB-A tops out around 5 Gbps with USB 3.2 Gen 119. Anker's guide says USB 3.2 Type-A ports offer speeds up to 20 Gbps22. VisionTek's guide says USB-C can deliver up to 40 Gbps using USB4 or Thunderbolt23. Belkin's page says USB-C supports data transfer speeds of up to 80 Gbps24. SC&T's guide says USB-C is the sole interface supporting USB 4.020.

Two cables on the sheet list a maker-stated data speed. UGREEN's spec sheet lists a data transfer rate of 0.48 Gigabits Per Second for its USB C to USB C 100W Fast Cable25. Titan lists USB 3.1 data transfer at 10 Gbps for the Titan Smart Cable PRO26. Anker's guide gives USB 2.0 a transfer speed of up to 480 Mbps, as a reference point27.

Which connector is easier to plug in, and how big is each?

USB-C is reversible and can plug in either way, according to EcoFlow's guide2. EcoFlow's guide says USB-A only inserts in one orientation1. Anker's guide says the USB-A connector measures approximately 12mm x 4.5mm3. Anker's guide says USB-C has an oval-shaped design measuring about 8.4mm x 2.6mm4. SC&T's guide says only USB-C offers direct video transmission through DP Alt Mode, and USB-A does not support it21.

How do real cables compare on one sheet?

The table “Charging cables on one sheet: maker-stated specs and the price on the maker's own page” holds four cables to the same rows. Anker's store page says the Anker 333 USB-C to USB-C Cable (3.3ft Nylon) supports charging of up to 100W with a compatible charger28. Anker's store page also says the Anker 333 cable does not support video output31. UGREEN says its USB C to USB C 100W Fast Cable supports PD3.0 and QC3.0 fast charging at 100W30. UGREEN also says the cable fully charges a MacBook Pro 16" in 90 minutes32.

Titan Smart Cable PRO supports up to 100W charging on USB-C PD, as Titan states it7. Titan's page says the cable charges 50% in 20 minutes33. The 240W PrismCore Cable™ supports up to 240W, according to Titan34. Titan's PrismCore page states 240W charging, 50% in 10 minutes35. The 240W PrismCore Cable™ price at titanpowerplus.com is $28.0536.

How long do the warranties and bend ratings run?

Warranty terms differ across the four cables. Anker's store page lists a 12-month warranty with the Anker 333 cable11. UGREEN's page lists a 2-Year Product Warranty12. Titan lists a 2-Year Limited Warranty for the Titan Smart Cable PRO13. Titan's PrismCore page says the 240W PrismCore Cable™ is backed by a 2-year warranty14.

Bend ratings are maker-stated, and not every maker on the sheet gives one. Anker's store page says the Anker 333 cable has a lifespan of 5,000 bends29. Titan lists a 300,000+ bend lifespan for the Titan Smart Cable PRO37. Titan says the 240W PrismCore Cable™ handles over 100,000 bends without breaking38.
