12V Digital Battery Capacity Indicator & Voltmeter with Dual USB Output

Product Description:

✨ Input Voltage: DC 12V (Optimized for 12V Lead-Acid or 3S/4S Lithium-ion/LiFePO4 battery banks).

⛔ USB Output Power: 5V / 2A Maximum (Shared combined total between both ports).

✨ Voltage Step-Down Efficiency: Up to 96% conversion efficiency via synchronous rectification (minimizes heat generation).

⛔ Static Input Current: 5–25mA (Adaptive; consumption lowers as the battery voltage drops).

✨ Voltmeter Accuracy: Approximately ±2% error tolerance.

⛔ Power Capacity Resolution (8-Segment LED Bar): Displays charge levels incrementally at 10%, 25%, 40%, 50%, 60%, 75%, 90%, and 100%.

✨ Physical Dimensions / Panel Cut-out Size: Approximately 45mm × 26mm × 18mm.

⛔ Environmental Limits: Operating temperature of -10°C to +65°C; non-condensing humidity between 10% and 80% RH
