Joyroom USB-C to USB-C Cable JR-S-CC100
TL;DR
- Joyroom JR-S-CC100 (store SKU JK05, GTIN 6956116750176, ~130 EGP) is a braided USB-C to USB-C cable whose retail box prints "100W PD" and "4ft / 1.2m", and one connector housing prints "100". CairoVolt's §7.4 honesty gate overrides that marketing: FNIRSI FNB58 PD Info detected NO E-marker chip — so this unit must NOT be treated as a 5A / 100W cable under USB-IF PD 3.0.
- Honest measured ceiling on sample CV-CB-JRSCC100-001: 20V/3A class. Peak carried 57.9W stable for 5 minutes into a JUWEI load from an Anker A2688 100W GaN when 20V/3A was requested. Voltage drop 0.21V at a controlled 3A/5V draw across the measured 121 cm tip-to-tip span (≈70mΩ VBUS+GND; ≈58mΩ/m) — within protocol §7.4 acceptable band for ~1.2m copper (≤0.30V at 3A).
- Disambiguation vs Joyroom PD siblings: JR-S-CL30 (30W, 0.28V @ 3A, 29.3W peak) is the phone-only entry rung; JR-S-CC60 gold sample (CV-CB-JRSCC60-001: 122 cm, 29g, 0.22V @ 3A, 58.4W) is the honest 60W non-E-marked twin. JR-S-CC100 on this bench is the same electrical class as CC60 — marketing name differs, measured physics do not. Buying CC100 expecting a step-up to laptop 100W over CC60 is the red-flag trap.
- A/B vs Anker Zolo A8060 braided C-to-C (gold sibling, CV-CB-A8060-001): Zolo has a live E-marker (FNB58 enumerated EPR-capable), 152 cm, 43g, 0.20V @ 3A (≈45mΩ/m), mid-span 36.8°C, and is the correct path toward MacBook Pro / 100W+ when paired with a matching brick. This JR-S-CC100 sample has NO E-marker, runs ~3.3°C warmer at identical 3A load (40.1°C), and must stay in the phone / Air / ≤60W bag. Same ~19W iPhone and 22–24W S24 numbers on both — the phone caps, not the cable.
- USB 2.0 data only (480Mbps) — charge and sync, no DisplayPort/Alt-mode/USB3 video. Tip-to-tip length measured 121 cm (box 1.2m; the store shortDescription "1m" is a listing conflict — tape wins). Single retail unit; production batches may vary. Joyroom is not on Anker cable recall lists (A8482/A8483/A8465 checked anker.com/product-recalls 2026-07-24). For MacBook Pro 14"/16" (96–140W) buy confirmed 5A E-marked C-to-C (Zolo A8060 / Anker A8865 class), not this SKU.
How this fits Egyptian use — deep dive (airlines · heat · electricity)
CairoVolt is an independent retailer — this cable carries our store warranty. JR-S-CC100 answers a buyer who saw "100W" on the box or the "100" stamp on the connector and assumed laptop-class 5A carry. On sample CV-CB-JRSCC100-001 that assumption fails the E-marker gate: no chip on FNB58 PD Info, so the honest class is the same 60W / 3A envelope as JR-S-CC60 (~123 EGP sibling) and below Anker Zolo A8060 (E-marked EPR path). Joyroom PD ladder at a glance: CL30 (~94 EGP, 30W) → CC60 / CC100 (~123–130 EGP, honest ~60W) → Zolo A8060 / A8865-class (pay for E-marker when you need 100W+). Six scenarios. RIGHT FOR: (1) IPHONE 15/16/17 DAILY DRIVER — Apple caps wired peak at ~20–27W (MacRumors); CairoVolt measured ~19W into an iPhone 13 via Anker A2147 30W PD with this cable — identical to Zolo at phone loads. (2) SAMSUNG S24 / S25 PPS — 25W Super Fast Charging 2.0 sits inside the measured ceiling; S24 pulled 22–24W steady from a 45W PPS brick. (3) MACBOOK AIR M2/M3 (30–35W per apple.com specs) — 3A / 60W headroom is enough; you do not need a 5A E-marked cable for Air. (4) UBER / CAREEM DRIVER with a USB-C car charger (Anker A2741 30W / Joyroom 60W car charger) — measured 121 cm reaches lighter-to-phone without stretching the braid. (5) STUDENT KIT (AUC/GUC/Cairo University) pairing a 45–65W GaN brick with phone + Air / Chromebook. (6) TRAVEL / EgyptAir carry-on — 27g measured (16g lighter than Zolo); bag-pocket friendly with any USB-C brick on Egypt's BS 1363-adjacent sockets. WRONG FOR: (7) BUYER WHO READ "100W PD" ON THE BOX AS A LAB RESULT — marketing ≠ E-marker. Without an E-marker this sample is not a verified 5A/100W path; publishing ≥100W would fail §11.1. (8) MACBOOK PRO 14"/16" at 96–140W — needs confirmed 5A E-marked C-to-C (Zolo A8060 / Anker A8865 class). (9) DISPLAYPORT / EXTERNAL MONITOR — USB 2.0 data only. LENGTH CONFLICT: store shortDescription said 1m; shallow stub and the retail box both said 1.2m (4ft) — fiberglass tape measured 121 cm tip-to-tip, so treat 1.2m-class as truth and the "1m" listing as a catalogue error. HEAT: Cairo July–August mean high ~35°C (WeatherSpark). Mid-span at 3A/5V was 40.1°C in a 28.6°C room — ~3.3°C warmer than Zolo A8060 (36.8°C) at the same load; expect higher on a sun-baked dashboard — shade the cable, never coil tightly under load. AUTHENTICITY: verify printed JR-S-CC100 / package codes, GTIN 6956116750176, and the "100" housing stamp on delivery — and still treat "100" as marketing, not CairoVolt-verified 5A. ELECTRICITY: fully charging an iPhone 15 (12.99Wh) from a 20W brick via this cable uses ≈0.017 kWh — under 4 piastres on EgyptERA Sept-2024 tariff.
Delivery to Cairo: Estimated 1–2 business days
