Joyroom 10000mAh Slim Power Bank | Dual USB | LED Display

For Your Time

Joyroom JR-T012: 10,000mAh × 3.7V ÷ 1000 = 37Wh nominal (§7.3 / §8 + Joyroom table). CairoVolt measured 30.8Wh usable on USB-A at 5V/2A (~83.2% of 37Wh) — inside the §7.3 80–90% band. 5V-referred ≈ 6,160mAh (30.8 ÷ 5); Joyroom lists ~5,800mAh rated @5V/2.1A — same post-conversion story within meter tolerance.
MARKETING CORRECTION (keep this): JR-T012 is NOT a 22.5W PD pack. Official ports = dual USB-A output at 5V/2.1A TOTAL shared max (~10.5W class) + Type-C / Micro input at 5V/2A. No USB-C output. No PPS. No 9V/10V QC/SCP advertisement on FNB58. If a listing says “22.5W / PD,” trust the printed table on the unit — our sample never saw that rail.
Phone math from measured Wh: iPhone 15 ≈ 2.16 est. charges (30.8 ÷ (12.99 × 1.10)); Galaxy A54 ≈ 1.47 est. (30.8 ÷ (19.05 × 1.10)); iPhone 15 Pro Max ≈ 1.64 est. Peak single USB-A into Galaxy A54 = 10.2W; dual-port shared ≈ 9.8W combined. Self-recharge 0→100% via USB-C in = 3 h 55 min at the 5V/2A (~10W) ceiling.
A/B honesty: vs Anker Zolo A110D (~1,270 EGP class) — same ~31Wh usable band, but A110D has real 22.5W USB-C + built-in cable; JR-T012 (~1,624 EGP listing) is bare dual-A ~10W. vs JR-W050 — same 37Wh class + MagSafe-compatible wireless + ~20W USB-C. vs recalled Anker A1263 — similar slow USB-A physics, but A1263 carries a US CPSC June 2025 model-window recall; Joyroom is a different brand (still verify packaging).
Recall / airline (checked 2026-07-24): no Joyroom JR-T012 hit on cpsc.gov Safety Gate search; Anker recalls A1257/A1263/A1647/A1652/A1681/A1689 do NOT apply. 37Wh << 100Wh cabin — EgyptAir / Nile Air / Air Cairo / Emirates / Flydubai / Turkish / Qatar / Saudia carry-on OK; Emirates/Flydubai ban in-flight USE since 1 Oct 2025. Buy for cheap dual-A capacity, not speed.

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

JR-T012 answers one Egyptian question honestly: "I need the cheapest known-brand brick that still tops up a phone ~twice on the metro — I do NOT need fast-charge theatre, MagSafe, or a built-in cable." Eight scenarios from measured 30.8Wh. RIGHT FOR: (1) STUDENT on Metro Line 1/2/3 with a USB-A cable already in the bag: 30.8Wh ≈ est. 2.16 iPhone 15 charges (30.8 ÷ (12.99 × 1.10)) or ~1.5 Galaxy A54 charges — enough for campus + evening WhatsApp. (2) CHILD / ELDERLY phone that still lives on USB-A wall habits: dual USB-A means two family phones at shared ~10.5W — slow (~3–3.5 h for a 5000mAh Android from empty at ~10W) but works without hunting a C-to-C cable. (3) EMERGENCY drawer pack next to a Micro-USB-era brick: Type-C AND Micro inputs refill from almost any old 5V/2A charger in Egyptian homes — useful when the only free brick is a leftover Micro wall wart. (4) BUDGET gift / COD under the ~1,600 EGP listing band when MagSafe (JR-W050) or built-in-cable Anker A110D is wasted money for a USB-A-only relative. (5) GLOVEBOX / BACKUP behind a primary Anker: leave JR-T012 for USB-A passenger phones; keep A110D or JR-W050 in the bag for yourself. (6) LOAD-SHEDDING PHONE-ONLY (30–60 min summer cut): one phone at ~8–10W draw → est. ~3–3.5 h messaging/data from 30.8Wh — covers a typical Cairo outage; cannot power a 12V WE/Vodafone router (USB-A only). WRONG FOR: (7) Anyone sold on marketplace “22.5W PD” text — FNB58 never saw a 9V rail; that claim is a listing error, not a hidden mode. (8) USB-C-only iPhone 15/16 owners without an A-to-C (or A-to-Lightning) cable — USB-C on this pack is INPUT only. (9) Laptop / iPad Pro PD / Galaxy Ultra 45W SFC chasers — no PD, no PPS, no 20V. Pick A110D (22.5W phone USB-C) or A1336 (laptop). (10) MagSafe wireless fans — that is JR-W050, not JR-T012. HEAT: Cairo July–August daily high ~35°C (WeatherSpark). Our sample hit 38.4°C shell after 15 min at ~10W discharge and 37.1°C during ~10W USB-C self-recharge at 28.2°C ambient — cool for the class; still keep off a parked-car dashboard (>60°C interior). AIRLINE: 37Wh << 100Wh — cabin OK on major Cairo carriers; never checked baggage; Emirates/Flydubai no in-flight USE since 1 Oct 2025. AUTHENTICITY: Joyroom ≠ Anker recall list, but grey-market clones exist — check hologram / Golden Code if supplied, MPN JR-T012, CE/FCC/UN38.3 marks. ELECTRICITY: recharging 37Wh at ~10W input ≈ 0.045 kWh ≈ 3–10 piastres on EgyptERA Sept-2024 tiers — NOT an AC system-efficiency % (no PZEM; §6.7).

Product FAQs

What is the price of Joyroom 10000mAh in Egypt?

The live price is displayed on this page. Review current stock, delivery options and the written warranty and return policy before ordering.

How many times does Joyroom 10000 charge a phone?

There is no fixed count. Compare usable watt-hours with the phone battery and allow for conversion loss, cable loss and phone use while charging.

Does Joyroom 10000 support fast charging?

No. This model uses a standard 5V/2.1A USB-A output and does not list a Quick Charge or other fast-charge profile. Total output is limited to about 10.5W, and actual speed depends on the phone, cable, temperature and battery level.

What makes Joyroom 10000 useful?

It combines a listed 10,000mAh cell rating, digital indicator, slim profile and two USB outputs. Compare the live price and exact port table with your needs.

Can Joyroom 10000 power a Bluetooth speaker?

Only if the speaker accepts USB power within the power bank port's listed 5V output. Check the speaker input requirement and use its recommended cable.

What's the difference between Joyroom 10000 and Joyroom 20000?

The 20,000mAh class has a higher cell rating but is typically larger and heavier. Compare the exact Wh, dimensions, weight, ports and current price; neither capacity promises a fixed charge count.

Does it come with a charging cable?

Yes, includes a short Micro-USB cable to recharge the power bank. We recommend USB-C cable for your phone.

How long does Joyroom 10000 take to recharge?

Use the printed input rating and a compatible source. Time varies with source power, cable, temperature, battery condition and use during charging.

Details

The Joyroom JR-T012 10000mAh Slim Power Bank is listed with a 37Wh cell rating, a standard 5V/2.1A USB-A output, two USB-A ports and a digital battery indicator. The display is an estimate and delivered energy is lower than the internal cell rating after conversion. Verify the printed input/output table, dimensions and package contents, then check the current price, stock and warranty terms before ordering.

The Bottom Line:

🔋 10,000mAh / 37Wh cell rating: usable USB energy and charge count vary after conversion.
⚡ Standard 5V/2.1A output: no fast-charge protocol; total is shared across the two USB-A ports.
📊 LED Display: provides an estimated remaining percentage.
📏 Listed 16.2mm thickness: confirm the dimensions and pocket fit on the supplied model.
💰 Current listing: Check the live price, stock and current warranty terms.

How to verify this model before buying

For model JR-T012, start with the manufacturer-rated Wh/mAh, input/output profiles and airline limits 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.

Standard Output, Display and Dual USB Ports

JR-T012 combines a standard 5V/2.1A USB-A output, a digital LED indicator and two USB outputs. It does not negotiate a fast-charge profile, and power may be shared when two devices charge. Treat the displayed percentage as an estimate and compare the live price and port table with alternatives.

Listed 16.2mm Slim Profile

The listing states a thickness of about 16.2mm (roughly 142.8 × 70.39 × 16.21mm); confirm that dimension and the exact model on the supplied label. A compact body can fit common pockets and small bags, but fit varies. If the package includes a Golden Code or other manufacturer verification label, follow its printed verification process rather than treating the code name alone as a guarantee of authenticity.

LED Display and Recharging

The digital percentage display is more detailed than four indicator dots but remains an estimate affected by load and calibration. Recharge time depends on the printed input profile, source, cable and temperature. Match a Joyroom charger to the exact input rather than relying on one universal time.

How to Estimate Charge Count:

📱 Phones: compare usable watt-hours with the phone battery and allow for conversion loss and use while charging.
🎧 Earbud cases: verify the case input and expect the number of top-ups to vary with its battery condition.
⌚ Wearables: use only a compatible charging accessory within the listed output.
🔌 Two devices: consult the shared-output table instead of assuming both retain maximum speed.

Before purchase:

Do not infer USB-C PD or wireless charging from the capacity name. Check JR-T012's printed ports and output profiles against your device. The 10,000mAh cell rating does not promise a fixed number of phone charges, and the LED percentage is an estimate.

Model	Joyroom JR-T012 10,000mAh Slim Power Bank (dual USB-A + LED %)
Cell Capacity (§8)	10,000mAh / 37Wh — 10,000mAh × 3.7V ÷ 1000 = 37Wh (Joyroom table + protocol §7.3)
Rated capacity @5V (vendor)	~5,800mAh at 5V/2.1A (Joyroom) — post-conversion figure, not cell mAh
Usable Energy (CairoVolt measured)	30.8Wh on USB-A at 5V/2A constant discharge (~83.2% of 37Wh — §7.3 80–90% band)
5V-referred capacity (§8)	~6,160mAh at 5V (30.8Wh ÷ 5V) — explains why “10,000mAh” ≠ 10,000mAh at USB
Outputs (honest)	2× USB-A — per-port language 5V/2.1A, TOTAL 5V/2.1A max shared (Joyroom). NO USB-C output. NO PD. NO PPS.
What marketplace “22.5W” means here	UNSUPPORTED on sample CV-PB-JRT012-001 and contradicted by Joyroom’s JR-T012 table. FNB58: 5V only on both USB-A ports. Treat as listing error.
Inputs / Self-recharge	Type-C 5V/2A + Micro-USB 5V/2A (Joyroom); CairoVolt timed 3 h 55 min 0→100% via USB-C from a 10W brick; FNB58 input peak ~9.6W
Display	Digital LED percentage — estimate only, not a lab instrument
Weight	Joyroom ~233.4g — CairoVolt measured 234g (Kkmoon 0.01g)
Dimensions	142.8 × 70.39 × 16.21 mm (Joyroom) — CairoVolt 143 × 70.5 × 16.3 mm
Vs Anker Zolo A110D	Same ~31Wh usable class. A110D = real 22.5W USB-C + built-in cable + ActiveShield lineage, NOT recalled. JR-T012 = USB-A only ~10.5W shared, dual Micro/C in, usually the “no fast charge” budget pick. Pay Anker for cable+speed; pay Joyroom for bare dual-A capacity.
Vs Joyroom JR-W050 (magnetic sibling)	JR-T012 = dual USB-A ~10W, no wireless, 30.8Wh measured, ~1,624 EGP class. JR-W050 = MagSafe-compatible 7.5W + ~20W USB-C wired, 32.1Wh measured, ~850 EGP class in some listings. Same 37Wh cell math; different job.
Vs Anker PowerCore A1263 (contrast carefully)	Similar slow USB-A day-pack physics (~31Wh usable, ~10–12W class). A1263 = single USB-A + Micro-USB in + US CPSC June 2025 recall window (Jan 2016 – Oct 2019 US manufacture) — serial-check mandatory. JR-T012 = dual USB-A + Type-C/Micro in, different brand, NOT on that Anker recall list. Do not treat “no Anker recall” as a blank safety cheque — still inspect packaging.
Airline	37Wh << 100Wh cabin — EgyptAir / Nile Air / Air Cairo / Emirates / Flydubai / Turkish / Qatar / Saudia carry-on OK with readable Wh label; never checked; Emirates/Flydubai no in-flight USE since 1 Oct 2025
Safety / Recall (verified 2026-07-24)	No Joyroom JR-T012 recall hit on cpsc.gov search (2026-07-24). Anker recall set A1257/A1263/A1647/A1652/A1681/A1689 does NOT apply (different brand). Verify CE/FCC/UN38.3 + packaging authenticity on delivery.
In the Box	Power bank + short Micro-USB cable for recharging the pack (verify live package; bring your own A-to-C / A-to-Lightning for modern phones)

Bench-tested at CairoVolt

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

The verdict

JR-T012 delivered 30.8Wh usable (83.2% of 37Wh) at a true ~10W USB-A ceiling. The useful finding is negative: no 22.5W PD on this SKU. Honest budget dual-A brick — buy for price and capacity, not speed.

How we tested it

Gold-depth power-bank bench per protocol §7.3 with an honesty priority on port truth (§8 Wh physics cross-checks). (1) Photographed the printed I/O table on the unit — confirmed dual USB-A 5V/2.1A TOTAL shared, Type-C/Micro 5V/2A in, 37Wh / 10,000mAh 3.7V label. (2) §8 nominal math: Wh_cell = 10,000mAh × 3.7V ÷ 1000 = 37Wh. (3) FNB58 handshake on BOTH USB-A ports: 5V only — no 9V/10V QC/SCP/PD advertisement matching a 22.5W claim. USB-C receptacle enumerated as INPUT path only (no output PDO set). (4) Full charge via USB-C input from a 10W 5V/2A brick, 30 min rest, discharge USB-A @ constant 5V/2A into JUWEI → FNB58 cumulative usable energy = 30.8Wh. Efficiency = 30.8 ÷ 37 = 83.2% (inside §7.3 80–90% band). 5V-referred mAh = 30.8 ÷ 5 = 6,160mAh. AVHzY CT-3 cross-check within 2%. (5) Peak into Galaxy A54 and iPhone 15 (via A-to-Lightning) logged; dual USB-A shared-budget test. (6) Input-speed: FNB58 between 10W brick and USB-C in → peak ~9.6W; 0→100% timed 3 h 55 min (Li-ion slows above 80% — expected). (7) Surface temp BENETECH GM320 (ε=0.95) after 15 min @~10W discharge and during ~10W recharge. Weight/dims on Kkmoon 0.01g + Mitutoyo. (8) RECALL gate 2026-07-24: cpsc.gov search for Joyroom / JR-T012 — no hit; anker.com/product-recalls confirms Anker set A1257/A1263/A1647/A1652/A1681/A1689 does NOT apply to Joyroom. Candid sibling contrast: A1263 is a recalled Anker model-window product with similar slow USB-A class energy — do not conflate brands. Independent corroboration (NOT our data): Joyroom JR-T012 public tables (37Wh, 5V/2.1A total, Type-C/Micro 5V/2A in, ~5,800mAh rated @5V). HONEST GAPS: no PZEM AC-input (no system efficiency % per §6.7); no PD/PPS rails to test (absent); no wireless path; single unit — batches may vary. Phone counts marked "est." use 30.8 ÷ (device Wh × 1.10 path loss).

✅ Strengths (measured)

30.8Wh measured usable at 83.2% cell→USB (30.8 ÷ 37) — physics-consistent with 37Wh; est. ~2.16 iPhone 15 charges from measured Wh
Dual USB-A + dual input (Type-C + Micro) — works with old cables still common in Egyptian homes and drawer chargers
Cool-running: 38.4°C shell @ ~10W discharge / 37.1°C during ~10W recharge (28.2°C ambient)
37Wh << 100Wh airline cabin — flyable on major Cairo carriers; slim 16.3 mm / 234g pocket-bag brick
Candid marketing correction published — FNB58 rejected 22.5W/PD listings; protects buyers from SKU confusion with A110D-class packs

⚠️ Limitations (measured)

NOT 22.5W — ~10.5W shared USB-A only; FNB58 found no 9V/10V fast-charge or PD/PPS rail on either port
No USB-C output — USB-C port is input only; modern C-only phones need an A-to-C cable in the bag
No PD / PPS / MagSafe — wrong tool for laptop, iPad Pro PD, Galaxy Ultra 45W, or wireless snap-on (use A1336 / A110D / JR-W050 instead)
Slow dual-device charging — shared 2.1A budget (~9.8W combined); self-recharge ~4h at 5V/2A vs ~3h on A110D 20W-class input
Brand / warranty channels typically weaker than Anker in Egypt — inspect packaging, Golden Code if supplied, and seller warranty terms
No PZEM AC-input — we deliberately do NOT publish a system efficiency % (§6.7)
Single unit tested — production batches may vary; Joyroom is NOT on Anker recall lists because it is a different brand, not because every grey-market unit is authentic
