FAQs

Can this charge an iPhone?

This model is specifically designed for USB-C devices. It will not work with iPhones using Lightning ports, but it is compatible with newer iPhone 15 models and later that utilize USB-C.

How do I know when the power bank needs to be recharged?

The device features integrated LED indicators that show the remaining battery level. When the lights are low or depleted, connect the power bank to a wall charger using a USB-C cable.

Can I use my phone while it is plugged into the power bank?

Yes, the design is compact enough to allow you to use your phone normally while it is being charged.

Is it TSA-compliant for air travel?

Yes, the 5000mAh capacity is well within the limits allowed by airlines for carry-on luggage.

Does it come with a cable to charge the power bank itself?

It typically includes a charging cable to recharge the power bank, but you do not need any cables to connect the power bank to your phone.

Troubleshooting

The device is not charging my phone.

Ensure the power bank has sufficient charge by checking the status lights and verify that the USB-C connector is fully seated in your phone's port, especially if you use a thick protective case.

The power bank charges very slowly.

Confirm that your device supports PD or QC fast charging protocols and that you are not running power-intensive background applications while charging.
