Answers to frequently asked questions

Can I charge multiple devices at the same time?

This power bank allows you to charge multiple smaller devices, but the number of devices connected simultaneously depends on the number of outputs and total power; it is recommended to consider a total output power of 20W for optimal performance.

Is wireless charging compatible with all phones?

The wireless feature only works with devices that support the wireless charging standard; please check if your phone supports it before using.

What does a capacity of 10,000 mAh mean in practice?

The capacity is large enough to charge an average smartphone several times; in practice, this means you can charge your phone up to twice, depending on the model and how you use it.

Is the power bank suitable for tablets or laptops?

It is useful for basic powering smaller tablets with lower consumption, but for modern laptops, the 20W output power is usually not sufficient for efficient charging.

Does portability affect the performance of a power bank?

Greater portability usually means slightly lower capacity or power, but the 10,000 mAh in this model is a good compromise between the two features.
