Large Capacity: 20,000 mAh battery (3.7 V / ~74 Wh) good for multiple full smartphone charges or several smaller charges.  Rated Usable Output (~): ~ 13,800 mAh at 5 V (typical 2 A) due to voltage conversion losses.  Battery Type: Li-ion polymer (often referred to as “Li-Po”).  Ports (Input + Output):Input: Micro USB + USB-C (both are 2-way ports for charging the powerbank). Output: 2 × USB-A + 1 × USB-C (so you can charge up to 3 devices simultaneously).  Fast Charging Support: 2-way fast charging up to 22.5 W (max output) supports Quick Charge, Power Delivery (PD), and PPS (Programmable Power Supply) standards.  Charging Time: Fully recharges itself in about 6 hours 30 minutes with a suitable charger.  Discharge Time (approx): With an 18 W load, provides ~ 3 hours 30 minutes of output before depletion.  Build & Portability: Compact form factor (approx 146 × 67 × 28.3 mm) and designed for portability easy to carry while travelling, commuting, or for everyday use.  Durable Housing: Sleek aluminium casing more durable than plain plastic.  Safety Features: “12-Layer Smart IC Protection” safeguards against over-charging, over-discharging, overheating, short-circuit, and excess current. Helps ensure safe operation. Pass Through Charging: It supports pass-through charging (i.e., you can charge the powerbank and a device simultaneously) handy if you want to plug in the bank and use it at the same time.
