What to know about UGREEN 100W USB C to USB C Cable, Fast Charging, 2-Pack, 6.6ft, Black | For iPhone 18/17/16/15, MacBook Pro/Air, iPad Pro/Air/Mini, Galaxy S26/S25/S24, XPS, Pixel, Switch. Built-in E-marker chip
This UGREEN-branded item is listed as a USB‑C to USB‑C charging cable 2‑pack that, according to the product name in the saved catalog snapshot, is rated for 100W, is 6.6 feet long, and includes a built‑in E‑marker chip. The listing also names a wide range of modern devices as compatible. The snapshot is not current, so this guide focuses on how to evaluate those stated features, what to verify before buying, and the practical tradeoffs to consider when choosing a USB‑C cable bundle like this one.
What the listing tells you (and what it doesn’t)
The only verified record we have is a saved catalog snapshot that contains the product name and a few identifiers. From that name you can read claims: UGREEN, USB‑C to USB‑C cable, 100W, built‑in E‑marker chip, two cables in the package, and a length of 6.6 feet. The snapshot also lists device models the seller positions as compatible. What’s missing from the snapshot are detailed specifications, certifications, explicit supported power profiles, durability specs, and up‑to‑date availability information. Treat the named capabilities as claims to be confirmed rather than proven attributes.
Compatibility: who the listing says the cables fit
The product name includes a long list of devices—phones, tablets, laptops and gaming consoles—indicating the seller intends this as a general USB‑C charging/data cable for contemporary devices. Because the saved snapshot is not current and contains no parsed technical specs, buyers should verify compatibility for specific models before relying on the cable for critical charging needs. Key checks are whether the cable supports the device’s required USB‑C power delivery profile, any manufacturer guidance about cable types, and whether data transfer expectations (if you need them) are met. The listing’s compatibility claims are a starting point, not a guarantee.
E‑marker chip and the implication for high‑current charging
The product name explicitly mentions a built‑in E‑marker chip. In general, E‑marker chips are used in USB‑C cables to identify cable capabilities to connected devices and chargers. The snapshot’s statement that the cable includes an E‑marker suggests the seller positions this item for higher‑power USB‑C applications. However, the snapshot does not provide the full technical details or certified test results for how the E‑marker is implemented. Confirm whether the seller or manufacturer documents the E‑marker implementation and any compliance testing before relying on it for high‑power charging scenarios.
Length, pack size, and practical trade‑offs
The listing name indicates a 6.6‑foot cable length and that two cables are included. Longer cables add convenience and flexibility around furniture and outlets, but they also can be heavier and less portable than shorter alternatives. A two‑pack can offer value if you want spares for travel and home, but be sure both cables are identical in capability. Since the snapshot lacks durability metrics and specifics about cable construction or strain relief, decide whether length and pack size meet your needs, and verify return options if durability or connector quality matters to you.
Durability, safety, and what to confirm
The snapshot provides no parsed specs about materials, jacket type, connector strain relief, or any safety or certification markings. Those items matter for longevity and user safety. Before purchasing, look for explicit manufacturer statements or documentation that confirm USB‑IF or other certifications (if important to you), details about the connector housings and shielding, and any stated testing for bend cycles or abrasion. If the listing or brand pages don’t supply that information, contact the seller or consider a cable with verified third‑party test data.
Purchase checklist and practical buying tips
Because the source is a saved snapshot, confirm these points before buying: verify the claimed 100W rating and the E‑marker implementation with the manufacturer or seller; confirm the exact usable length; check whether both cables in the 2‑pack share the same specs; request documentation of any safety or USB‑IF compliance; and review current customer feedback and return policy. Also verify the seller identity and that replacement or warranty service is available if the product listing lacks explicit post‑sale support information.
Who should consider it?
This product—per the saved listing name—may be best for shoppers who want two long USB‑C to USB‑C cables from a mainstream accessory brand and who prioritize a cable that the seller claims includes an E‑marker chip and a 100W rating. It could suit people who prefer a longer reach and a spare cable in a household or for travel. Because the snapshot lacks detailed test data and current listing status, prospective buyers who need certified, independently verified performance should seek additional documentation before purchase.
Before you buy
Key things to verify: the authenticity of the 100W claim and how it was measured, whether both cables in the 2‑pack have identical specifications, documentation of the E‑marker implementation, any safety or USB‑IF certifications, up‑to‑date seller information and warranty/return policies. Also confirm actual length and connector quality through recent photos or manufacturer documentation, since the saved snapshot may not reflect current packaging or specs.
Reasons to consider
- Brand listed as UGREEN, a recognizable accessory maker (product_name and brand present in snapshot).
- Described in the snapshot as USB‑C to USB‑C, matching the modern connector standard for many devices.
- Listing name claims a 100W rating, which indicates the seller markets it for higher‑power USB‑C usage (from product_name).
- Package is labeled as a 2‑pack with a 6.6‑foot length, offering two long cables in one purchase (from product_name).
- The product name states a built‑in E‑marker chip, which the seller uses to indicate capability identification between devices and chargers.
Limitations and unknowns
- Unknown: The snapshot does not include detailed certification evidence (for example, USB‑IF certification) — documentation should be requested from the seller or manufacturer.
- Unknown: The snapshot provides no parsed specifications about data transfer speeds, supported PD profiles, or verified power/delivery behavior; these are not stated in the saved record.
- Unknown: Durability metrics (bend cycles, jacket material, connector design/life) are not present in the snapshot; real‑world longevity is unverified here.
- Snapshot not current: the source is a saved catalog listing snapshot and may not reflect current product details, packaging, or availability (source and snapshot_not_current fields).
Our bottom line
The saved catalog snapshot identifies a UGREEN USB‑C to USB‑C cable 2‑pack that the seller lists as 100W capable, 6.6 feet long, and fitted with an E‑marker chip. Those claims suggest a focus on higher‑power charging and flexible reach, and a two‑cable bundle can be convenient. However, the snapshot lacks supporting technical documentation and is not current. If you’re considering this item, confirm the key technical and certification details with the manufacturer or seller before relying on it for high‑power charging or mission‑critical use.
Common questions
Does this cable support 100W charging?
The product name in the saved snapshot claims a 100W rating, but the snapshot does not include technical verification or certification documents. Verify the 100W capability directly with the manufacturer or seller and ask for specification sheets or testing evidence before assuming it will deliver that level of power.
What devices is it compatible with?
The snapshot lists many modern phones, tablets, and laptops as compatible in the product name. That indicates the seller positions it for widespread USB‑C use, but compatibility with a specific device depends on that device’s power and data requirements. Confirm the cable’s supported power profiles and data speeds if your device has particular needs.
Is the E‑marker chip included important?
The snapshot explicitly states an E‑marker chip is built in. Generally, E‑marker chips are used to communicate cable capabilities between devices and chargers. For higher‑power USB‑C applications this is commonly relevant, but the snapshot provides no implementation details—request documentation from the seller if the E‑marker’s specifics matter to you.
Are both cables identical in the 2‑pack?
The listing name indicates a 2‑pack, but the saved snapshot does not include parsed specs confirming both cables’ identical capabilities. Ask the seller to confirm whether both included cables have the same length and electrical specifications.
Should I be concerned about safety certifications?
Yes. The saved snapshot does not show safety or USB‑IF certification details. If safety certifications or independent testing are important to you, request evidence from the manufacturer or choose a cable with clear, documented certification.
