Which model is my Fitbit?

Hi, everyone! Someone gifted me this used Fitbit a while ago, but without the charger. I have no idea which model it could be so I can start looking for a charger to buy. I googled it and to me (someone who knows very little about Fitbits), it looks like Fitbit Inspire. Does anyone recognise the model? It's not charged so I can't turn it on and check. I appreciate any help!!
