Question about LotusGrill Original with USB

Could the Jackery SolarSaga 100 W be sufficient for this?

The power supply for the grill's fan is provided by 4 x AA 1.5V DC batteries. Alternatively, it can also be operated via USB. The operating instructions state:
"...
The LotusGrill can be operated either with batteries or with the supplied USB power cable and a USB power supply unit (not included). As soon as the round plug
is plugged into the grill, the battery compartment is disconnected.
..."
and still
"...
The USB power cable cannot be used to charge rechargeable batteries or accumulators.
..."

Electrical engineering is not my area of expertise, but I assume that if the solar cells have a suitable output and a USB-compatible connection, the fan can also be operated directly via solar cells. Or via a BatteryPowerPack that is first charged via photovoltaics.

I checked again, but I didn't find any information about the power of the fan either on the barbecue itself or in the operating instructions. It can't be much, because the blower only moves air and doesn't have an integrated heater - like a hairdryer, for example - that really needs power. I'd guess something around 100 - 200 W.
That would be a question to ask the manufacturer:

In any case, it's a cool piece of equipment that's fun to use because you can actually get started in no time at all.
