Battery Charging

Stable current – A wall charger delivers a constant 5 V output, so the tracker’s battery-management circuit can charge at its optimal rate.
Full top-off – Many power banks shut down automatically when the current draw falls below a threshold; the tracker may stop charging before it reaches 100 %, reducing runtime.
No calibration errors – Irregular trickle-charging from power banks can confuse the device’s battery gauge, leading to false “low-battery” alerts.

Avoid fast-charge bricks (> 5 V or “Quick-Charge” logos); they can overheat the battery.
Charge at least once every 3 weeks even if the tracker is idle, to keep the lithium-ion cells in good health.
Keep it cool – charge in a shaded, well-ventilated spot; extreme heat shortens battery lifespan.
Fully recharge after every recovery event when continuous tracking drains the battery faster.
