In some cases, you may be able to charge your WiFiBOX with a power bank. However, we generally do not recommend it.
Why power banks are not recommended
Depending on compatibility between the power bank and your WiFiBOX, the device may not charge properly.
For more reliable charging, we recommend using a standard wall charger.
Charging issues caused by compatibility with a power bank are not covered by our support.

To help ensure reliable use, please prepare a suitable charger for your WiFiBOX.
