iWALK LinkPod Switch|with 2-in-1 Connector Portable Charger - 50 units

With a fast-charging USB-C power adapter above 18W, it takes about 1.7 hours to fully charge the power bank; for other power adapters, it will take longer.

You can tell how much power is left by the power level indicator:
3 LEDs are always on to indicate the charge level is at 68-100%.
2 LEDs always on charge level, indicates 31-67% charge level
1 LED always on power level, indicates the power level at 5-30%
1 IED light blinking, power ≤5%

To preserve battery lifespan, use and recharge at least once every 4 mouths.
Use original or certified cables.
Do not expose to liquids.
Avoid use at too low or too high a temperature

Press and hold the power on/off button or automatic power off after 30 seconds of non-use.

Simultaneous charging of the phone and power bank at the same time and pass-through charging will fully charge the mobile phone first, then charge the product.

The capacity reduction during charging is due to a 30% to 45% energy loss in the battery cells and conversion circuitry. Therefore, a fully charged LinkPod Switch (5K) offers an estimated 3300mAh to power devices.
