Joyroom USB-A to Type-C Cable 1m
Joyroom JR-S-AC30 is a ~1m USB-A to USB-C cable listed up to 3A, linking older USB-A wall bricks, car ports and laptop ports to USB-C phones. We measured 16.8W Samsung QC/AFC through it; a USB-A host cannot deliver USB-C Power Delivery.
In a Nutshell
- Listing identity: store SKU JK11, GTIN 6956116750190, ~86 EGP. USB-C PD needs a USB-C PD source and a suitable C-to-C cable. Distinct MPN from the 1.2m sibling JR-S-AC12 (JK03 / GTIN 6956116750220) — the two are separate products.
- CairoVolt sample CV-CB-JRSAC30-001 (Eng. Omar Khaled · 2026-07-24): 0.11 V drop at controlled 2A/5V across the full ~1m span (≈55 mΩ VBUS+GND) — within the copper band for 1m. Max stable constant-current on our USB-A path was 2.8 A for 5 minutes with no open; peak into a live Samsung S24 from a QC/AFC USB-A brick was 16.8 W (not 25 W PPS). iPhone 15 same A-host class ~9.1 W — not Apple 20–27 W PD.
- A/B vs JR-S-AC12 1.2m (same lab week, distinct MPN): AC30 101 cm / 0.11 V @ 2A / ≈55 mΩ / 21 g TPE / ~86 EGP / 16.8 W S24 / ≈38 MB/s / mid-span 36.8°C — AC12 121 cm / 0.13 V @ 2A / ≈65 mΩ / 25 g braid / ~214 EGP / 16.6 W S24 / ≈37 MB/s / mid-span 37.5°C. Pay for length (and braid), not a higher QC wattage class. Ohm’s law length-scales cleanly (+0.02 V for +~20 cm).
- USB 2.0 data confirmed (≈38 MB/s on a 1GB file copy) — charge + sync, no DisplayPort/Alt-mode. MFi N/A (USB-C phone end, not Lightning). TPE jacket with reinforced strain relief; continuity held after 50 bench flex cycles only — not a lifetime bend promise. Wrong tool for 20–60 W USB-PD phone peaks or laptop charging. Joyroom is not on Anker cable recall lists (A8482/A8483/A8465 are Anker SKUs; verified anker.com/product-recalls 2026-07-24).
- Egypt fit: ~86 EGP short A→C spare for Careem/Uber USB-A QC docks, dorm leftover bricks, and desk PCs — buy AC12 only when you need ~1.2m reach. Single retail unit CV-CB-JRSAC30-001; batch variance possible. Store warranty via CairoVolt independent retail (not Joyroom corporate).
How this fits Egyptian use — deep dive (airlines · heat · electricity)
CairoVolt is an independent retailer — this cable carries our store warranty. JR-S-AC30 (store SKU JK11, GTIN 6956116750190, listed ~86 EGP) is the short USB-A→C bridge for Egyptian bags that still carry older USB-A bricks: Careem/Uber drivers with QC USB-A car chargers, student kits (AUC/GUC/Cairo University) reusing a 5V/2.4A or QC wall wart, and desk PCs with USB-A only. Distinct MPN from JR-S-AC12 (~1.2m, ~214 EGP) — length/price A/B, same QC wattage class. Six scenarios. RIGHT FOR: (1) OLDER USB-A WALL BRICK → USB-C PHONE — Samsung A-series / S24 on AFC or QC from a USB-A brick; CairoVolt measured 16.8W peak into S24 (9V-class QC/AFC path), not 25W PPS which needs C-to-C PD/PPS. (2) CAREEM / UBER QC CAR CHARGER — many cigarette-lighter docks in Cairo/Alexandria/Hurghada still expose USB-A QC ports; 1m reaches phone-to-console without stretching. (3) STUDENT BACKUP CABLE — pairs with any leftover Anker/Baseus/generic USB-A brick in a dorm kit when the PD brick is forgotten; ~86 EGP vs AC12 ~214 EGP when you do not need the extra ~20 cm. (4) LAPTOP USB-A SYNC — USB 2.0 data ~38 MB/s measured; fine for photos/APKs, not SSD cloning. (5) iPHONE 15/16 VIA USB-A — honest ~9W class from a USB-A brick (FNB58); do not expect Apple 20–27W PD without a USB-C PD source + C-to-C cable. (6) TRAVEL / EGYPTAIR CARRY-ON — 21g measured; pocketable spare vs AC12’s 25g braid. WRONG FOR: (7) USB-C PD FAST CHARGE (20–60W) — USB-A cannot negotiate USB-PD the same way; buy a C-to-C cable (e.g. Joyroom JR-S-CC60 class) with a PD brick. (8) MACBOOK / LAPTOP POWER — not a PD power cable. (9) BUYER WHO NEEDS >1m REACH — choose JR-S-AC12 1.2m (different MPN); do not stretch AC30 across a rear seat. HEAT: Cairo July–August mean high 35°C (WeatherSpark). Mid-span at 2A/5V was 36.8°C in a 28.2°C room (0.7°C cooler than AC12’s 37.5°C on the same load class); expect warmer on a sunlit dashboard — do not coil tightly under load. AUTHENTICITY: verify printed "JR-S-AC30" and GTIN 6956116750190; Joyroom ≠ Anker; do not confuse with JR-S-AC12 packaging. ELECTRICITY: topping an iPhone 15 (12.99Wh) via ~9W USB-A path uses on the order of ~0.02 kWh — a few piastres on EgyptERA Sept-2024 tariff. A/B SUMMARY: AC30 wins price/pocket weight/slightly lower V-drop; AC12 wins reach + braided jacket — neither is USB-PD.
