The SMOK Acro Replacement Pods are designed for the SMOK ACRO 25W Pod System and designed perfectly for salt nicotine. The SMOK ACRO Replacement Pod does not protrude completely out of the device. This system allows the device to remain sleek and flush with the pod installed while the whistle tip protrudes slightly for a comfortable vaping experience. Juice can be filled by unplugging a silicone tab located on the side of the pod with a maximum juice capacity of 2ml. Each pod is securely connected to the device via a magnetic connection.
