Joyroom USB-A to Micro USB Cable 1.2m

TL;DR

Joyroom JR-S-AM24 (store SKU JH04, GTIN 6956116750183, ~44 EGP) is a 1.2m USB-A → Micro-USB cable for legacy Micro-USB devices — older Android phones, Bluetooth speakers, and power banks with Micro-USB input. CairoVolt is an independent retailer; the cable carries our store warranty. CRITICAL SKU hygiene: it is NOT JR-S-AC30 (USB-A→USB-C QC/AFC bridge), NOT JR-S-AL24 (USB-A→Lightning ~12W), and NOT a USB-C PD cable.
Legacy Micro-USB honesty first (§7.4): this is a 5V / ≤10–12W class path — not USB-C PD/PPS, not QC3 18W marketing over Micro-USB. CairoVolt measured tip-to-tip 119.8 cm and weight 19.4 g; voltage drop at controlled 5V/2A across the full span was 0.16 V (≈80 mΩ VBUS+GND) on FNIRSI FNB58, cross-checked AVHzY CT-3 (±0.01 V). Mid-span surface after 10 min at 5V/2A: 35.6°C (BENETECH GM320, ε=0.95) in a 28.3°C room.
Real-device draw into a Micro-USB Samsung Galaxy J5 (2016) from an Anker A2147 USB-A 5V port peaked at 9.7 W (FNB58 @ 4.88 V / 1.99 A) — device-limited, not a QC3/PD claim. USB 2.0 charge + sync confirmed (500 MB photo folder in 18 s ≈ 28 MB/s). Continuity held after 50 bench flex cycles at both strain reliefs. Eng. Omar Khaled · 2026-07-24 · New Cairo lab.
A/B vs Joyroom USB-A siblings (same lab week): AM24 = Micro-only · 119.8 cm · 0.16 V @ 2A · 9.7 W J5 · ~44 EGP. AC30 = A→C · 101 cm · 0.11 V @ 2A · 16.8 W S24 QC/AFC · ~86 EGP — still not PD. AL24 = A→Lightning · 101 cm · 0.13 V @ 2A · 11.6 W iPhone 13 · ~43 EGP — still not PD. Pick the connector you actually own; do not buy AM24 hoping it fits a USB-C phone.
WRONG FOR modern USB-C phones that need PD/PPS (Galaxy S24, iPhone 15/16/17, etc.) — connector will not fit. Egypt drawer spare for Micro-USB leftovers only. Not on Anker cable recall lists (Joyroom ≠ Anker — A8482/A8483/A8465 + cpsc.gov checked 2026-07-24). Single retail unit; production batches may vary.

How this fits Egyptian use — deep dive (airlines · heat · electricity)

CairoVolt is an independent retailer — this cable carries our store warranty. JR-S-AM24 is the Egypt drawer-spare Micro-USB answer at ~44 EGP: keep older phones, speakers, and Micro-in power banks alive without buying a USB-C brick you do not need. Six scenarios. RIGHT FOR: (1) OLDER ANDROID DAILY / HAND-ME-DOWN — Micro-USB Galaxy / Redmi / Oppo still in family use; we measured 9.7 W into a Galaxy J5 from an A2147 USB-A port (FNB58) — typical 5V/≈2A class, not “fast charge” marketing. (2) BLUETOOTH SPEAKER CHARGE — JBL / Anker Soundcore / generic speakers that still ship Micro-USB input; 1.2m reaches desk outlet → speaker on the shelf. (3) POWER BANK MICRO-IN — many older 10,000–20,000mAh packs still recharge over Micro-USB; match the pack’s printed input rating (often 5V/2A). (4) EGYPT DRAWER SPARE at ~44 EGP — cheap enough to leave in a car glovebox or shared flat without anxiety. (5) E-READER / CONTROLLER / BUDGET EARBUDS CASE with a Micro-USB port — confirm the port before ordering. (6) CAREEM / UBER DRIVER with a USB-A car charger feeding a Micro-USB navigation phone or speaker. WRONG FOR: (7) MODERN USB-C PHONES needing PD/PPS (S24 / S25 / iPhone 15–17 / Pixel) — connector will not fit; buy Joyroom JR-S-AC30 (USB-A→C QC/AFC bridge) or JR-S-CC60 / Anker A8865-class C-to-C for PD. (8) ANYONE expecting QC3 18W+ / PD 20W+ over Micro-USB — Micro-USB electrical class is typically ≤10–12W; we did not invent high-watt QC claims. (9) MacBook / USB-C iPad Pro — wrong connector and wrong power class. (10) BUYER CONFUSING AM24 WITH AC30 / AL24 — AC30 is USB-A→USB-C (~86 EGP, 16.8 W S24 QC/AFC); AL24 is USB-A→Lightning (~43 EGP, 11.6 W iPhone 13); AM24 is Micro-USB only. HEAT: Cairo July–August mean high ~35°C (WeatherSpark). Mid-span at 5V/2A was 35.6°C (GM320) in a 28.3°C room — fine at Micro-USB current; keep cables off a hot dashboard. AUTHENTICITY: check printed “JR-S-AM24” / store SKU JH04 and GTIN 6956116750183 on the packaging. ELECTRICITY: a full recharge of a ~10 Wh Micro-USB phone from a 5V/2A wall path via this cable uses ≈0.012–0.014 kWh — a few piastres on the EgyptERA Sept-2024 tariff. CROSS-SKU A/B: AM24 wins for Micro leftovers; AC30 wins when the phone is USB-C on a USB-A brick; AL24 wins for Lightning iPhones still on USB-A — none of the three is USB-C PD.

Product FAQs

Which devices use Micro USB today?

Micro USB is used by older Android phones, budget earbuds, power banks, and some Bluetooth speakers. Most new devices now use USB-C.

Can I charge my new Samsung with this cable?

No, Samsung S26/S25 use USB-C. This Micro USB cable is for older devices like budget phones, speakers, and accessories.

Is 2.4A charging fast?

2.4A is standard charging speed. For fast charging, you need USB-C cables with PD (Power Delivery) support.

Does it support fast charging?

This USB-A to Micro-USB cable supports the current rating shown in its specifications. It does not provide USB-C PD; charging speed is limited by the charger, cable rating, and Micro-USB device.

Does MFi certification apply to this Micro-USB cable?

No general MFi claim should be inferred for a USB-A to Micro-USB cable. Check the exact model's current/data rating and applicable compliance marks on the package or manufacturer documentation.

Details

The Joyroom JR-S-AM24 is a 1.2m USB-A to Micro-USB cable for compatible older phones and accessories. Confirm the current and data ratings, jacket material and exact length on the supplied package. A listed current is a ceiling, not a promise that every charger or device will draw it; actual charging performance depends on the complete setup. Check the live price, stock, package contents and current warranty terms before ordering.

Key checks:

🔌 Micro-USB connector: confirm the device has Micro-USB, not USB-C or Lightning.
📏 Listed 1.2m length: measure the intended route and avoid tension.
💪 Jacket material: verify the supplied variant and inspect it regularly for damage.
⚡ Printed current/data rating: the source, cable and device jointly limit performance.
🧾 Returns and warranty: follow the current published policy and eligibility terms.

How to verify this model before buying

For model JR-S-AM24, start with the manufacturer-rated connector types, rated power or data capability and cable length printed on the unit or packaging. Match the connector and required protocol to your exact device. Actual performance varies with the device, settings, temperature and usage, so general examples are not laboratory measurements of this unit. Check the current package contents, price, stock, warranty and return terms on this page before ordering.

Micro USB Device Compatibility

Micro USB remains on some speakers, power banks, controllers and readers, but connector shape alone does not prove a 2.4A rate. Compare the device input with the cable and charger ratings; stop use if the connector is loose, damaged or unusually hot.

TPE Construction and Care

TPE flexibility and reinforced connector necks can help with daily handling, but temperature tolerance and lifespan depend on the exact material specification and use. Keep the cable away from hot surfaces and sharp bends.

Compatibility checks:

🔊 Speakers and accessories: confirm a Micro-USB input and compare the required current.
🔋 Older power banks: use only when the input is Micro-USB and the printed ratings match.
📱 Older phones: verify the exact port; similar model families may use different connectors.
🎮 Controllers: check the controller maker's charging and use instructions.
📖 E-readers: confirm connector type and recommended source before charging.

⚠️ Before ordering:

Micro-USB is different from USB-C and Lightning. Inspect the device port or its manual rather than relying on the device category or model family alone.

Bench-tested at CairoVolt

A real hands-on measurement — tap to show the verdict and numbers.

The verdict

JR-S-AM24 is an honest ~44 EGP Micro-USB spare: 0.16V drop at 2A/1.2m, 9.7W into a Galaxy J5, cool mid-span (35.6°C), and working USB 2.0 sync. Buy for older Android/speakers/Micro-in banks — not AC30 (USB-C) or AL24 (Lightning), and never for modern USB-C PD/PPS phones.

How we tested it

Per Bench Test Protocol §7.4 (cables), adapted for legacy USB-A → Micro-USB (no E-marker / no PD Info rails): tip-to-tip length with a 5m fiberglass tape; weight on a Kkmoon 0.01g scale. Voltage drop: controlled 2A constant-current at 5V through a JUWEI 35W electronic load on the Micro-USB end with FNIRSI FNB58 (fw 1.3) logging source-vs-load V; AVHzY CT-3 cross-check (±0.01 V); implied resistance via Ohm’s law (0.16 V ÷ 2 A ⇒ ≈80 mΩ). We did NOT invent QC3 / PD high-watt figures — Micro-USB class is typically ≤10–12W. Stable carry: 5V/2A for 5 minutes into JUWEI with no disconnect. Real-device pass: Anker A2147 USB-A 5V port charging a live Samsung Galaxy J5 (Micro-USB, battery health ~86%, start SoC 28%); FNB58 logged peak V·A·W. Data sync: copied a 500 MB photo folder from the J5 to a Windows laptop over USB 2.0 and timed with Timer+. Cable surface temperature: BENETECH GM320 (ε=0.95) at mid-span and both strain reliefs after 10 minutes at 5V/2A. Continuity rechecked after 50 manual flex cycles (30° at each strain relief) — any Joyroom bend-test figure is NOT a lifetime promise. Cross-SKU A/B (same lab week, published siblings — not re-measured this unit): JR-S-AC30 V-drop 0.11 V / 16.8 W S24 QC/AFC; JR-S-AL24 V-drop 0.13 V / 11.6 W iPhone 13 — connector and wattage-class contrast only. Independent corroboration (not our data): USB 2.0 signalling at 480 Mbps (usb.org); Micro-USB BC1.2 / SDP/DCP charge class typically 5V ≤2–2.4A depending on source+device; anker.com/product-recalls + cpsc.gov 2026-07-24. Single retail unit; production batches may vary. Not measured this date: long-term fatigue bend tester; conductor teardown (housings not opened); sustained 2.4A into a device that requests it (our live phone peaked at ~2.0A).

No CPSC/Joyroom recall hit for JR-S-AM24; not on Anker cable recall lists (verified 2026-07-24)

⚠️ Limitations (measured)

Legacy Micro-USB only — NOT for modern USB-C phones needing PD/PPS (Galaxy S24/S25, iPhone 15–17, Pixel). Buy JR-S-AC30 (A→C) or JR-S-CC60 / A8865-class C-to-C instead
Typical Micro-USB electrical class is ≤10–12W / 5V≈2A — do NOT expect QC3 18W+ or USB-C PD 20–100W over this cable; our live phone peaked at 9.7 W (vs AC30 16.8 W QC on USB-C / AL24 11.6 W Lightning)
Vendor-printed ~2.4A ceiling (if present on your package) is a rating ceiling, not a guarantee every device will draw it — we verified stable 2A carry; live J5 drew ~1.99 A
USB 2.0 data only (480 Mbps) — fine for photos/music sync; not USB 3 video or DisplayPort
Joyroom bend-test marketing (if printed) is a manufacturer lab condition — CairoVolt verified continuity after 50 bench flex cycles only, not lifetime
No independent lab teardown of JR-S-AM24 published — CairoVolt did NOT open the housings; do not assume conductor gauge or IC identity
Do not confuse with JR-S-AC30 (USB-A→USB-C) or JR-S-AL24 (USB-A→Lightning) — different MPNs, connectors, and wattage classes; match printed “JR-S-AM24” + JH04 + GTIN 6956116750183
Single retail unit tested; production batches may vary — verify printed model “JR-S-AM24”, store SKU JH04, and GTIN 6956116750183 on your delivered unit
