| Capacity | ~ 20,000 mAh (≈ 74 Wh) Li‑Polymer battery. Some of this is lost in conversion, so usable capacity may be ~ 11,000‑13,000 mAh at 5V. tyshen.com+3cliptec.com+3rebeltec.eu+3 |
| Max Output Power | 22.5 W total output under ideal conditions. sz-powerbank.en.made-in-china.com+2tyshen.en.made-in-china.com+2 |
| Ports | 4 ports: typically a mix of USB‑A ports, USB‑C (which may support both input/output), possibly one port dedicated or special (e.g. cable‑built‑in). rebeltec.eu+3tyshen.com+3cliptec.com+3 |
| Inputs (to charge the power bank) | USB‑C and/or MicroUSB. Typical input specs: 5V/3A, 9V/2A, 12V/1.5A or similar — often using QC or PD fast‑charge protocols. tyshen.en.made-in-china.com+2rebeltec.eu+2 |
| Outputs (charging your devices) | One or more ports supporting higher currents/voltages: e.g. USB‑A might provide 4.5V/5A, or 9V/2A, or 12V/1.5A. USB‑C port likely supports PD 20W or close. When using multiple ports at once, per‑port power may be reduced. sz-powerbank.en.made-in-china.com+2tyshen.com+2 |
| Simultaneous Device Charging | Can typically charge 3‑4 devices at once (depending on port layout). Total output capacity is shared among active ports. foneng.net+2cliptec.com+2 |
| Dimensions & Weight | Rough dimensions around 140‑150 × 65‑70 × 25‑30 mm. Weight often in the 400‑450 g range. tyshen.en.made-in-china.com+2rebeltec.eu+2 |
| Input / Output Voltage/Current Ranges | Usually covers standard fast‑charging voltages: 5V, 9V, 12V. Currents like 2‑3A depending on voltage. USB‑A ports may have different maximums (higher at lower voltage). cliptec.com+2sz-powerbank.en.made-in-china.com+2 |
| Safety & Protection | Over‑charge, over‑discharge, over‑current, over‑voltage, short circuit protection. Housing often ABS + PC fire‑resistant material. sz-powerbank.en.made-in-china.com+1 |
| Indicators / Features | A display or LED indicators for remaining battery %, maybe status of charging. Some include built‑in cables, flashlight, or even LCD display |
