In some cases, you may be able to charge your WiFiBOX using a computer's USB port. However, we generally do not recommend it.
Why computer USB ports are not recommended
Some computer USB ports are not designed primarily for charging, so they may not provide a stable power supply.
Depending on compatibility between the computer and your WiFiBOX, the device may also fail to charge properly.
Charging issues caused by compatibility with a computer's USB port are not covered by our support.

For more reliable charging, we recommend using a standard wall charger.
