Here’s the spec breakdown for the Rock Power Bank 10000mAh P73 PD 22.5W Fast Charging Power Bank With Built‑in Dual Cable-style power bank (model commonly referenced as Rock P73 / similar built-in dual cable 22.5 W PD 10000 mAh power bank). Specific model listings vary slightly, but the core specs below reflect typical Rock 22.5 W PD power banks with built-in cables:

🔋 Battery & Capacity
Battery capacity: 10,000 mAh (~37 Wh) lithium-polymer battery — standard for portable use.
Rated usable capacity: Typically ~5,300–6,000 mAh at 5 V output (actual delivered energy is lower than rated).

⚡ Fast Charging & Output
Fast charging support: Up to 22.5 W output power with USB-PD / QC-type protocols, suitable for many phones and small tablets.
PD / QC support: Works with USB-PD (20 W & up), quick charge, and some brand fast-charge profiles (e.g., Huawei’s 22.5 W).

Output details (typical ranges):
Built-in USB-C cable output: ~5 V/3 A, 9 V/2.22 A, 10 V/2.25 A, 12 V/1.5 A (up to ~22.5 W max).
USB-A / extra port outputs (if included): ~5 V/3 A, 9 V/2 A (varies by exact layout).
Total output: PD/QC max ~22.5 W usually from the highest-powered port.

🚨 Many Rock power banks with built-in cables may include multiple ports (e.g., USB-A + USB-C + built-in cable), but the combined output power is typically managed so total doesn’t exceed ~22.5 W.

🔌 Ports & Cables
Built-in dual cables: Usually USB-C and iP or USB-C + iP cable integrated into the body for charging phones without carrying extra leads.
External ports: Often has an extra USB-A and/or additional USB-C port for simultaneous charging of multiple devices.

📈 Input / Recharge
Input (recharging the power bank): Typically USB-C input 5 V/3 A, 9 V/2 A, 12 V/1.5 A (PD fast recharge supported).

🛡️ Safety & Build
Protection: Over-current, over-voltage, over-temperature safety protection integrated (common in Rock power banks).
Material: Fire-resistant ABS + PC casing mostly.

📏 Physical
Size & Weight: Around ~110×~70×~18 mm and ~200-240 g depending on exact variant.
Design: Compact, travel-friendly with built-in cables for on-the-go use.

👍 Good For
Portable daily use to recharge phones and small devices quickly.
No-cable-needed convenience thanks to built-in charging leads.

⚠️ Notes
Rated capacity and delivered output vary in real-world usage due to conversion losses and charging protocols.
“22.5 W” refers to maximum achievable output under PD/QC; actual speeds depend on device negotiation and cable quality.
