The Aspire Nautilus AIO atomizer is the famous and popular Nautilus BVC coil, it also uses nichrome wire. The Aspire Nautilus AIO comes supplied with two coils both rated at 1.8 ohms, one for regular e-liquid and one for use with nicotine salts, though it works equally well with normal e-liquid. Whatever type of coil you use, the standard Nautilus BVC or the nic-salts Nautilus BVC, both are easy to install. Simply remove the pod by squeezing the side buttons on the device, then remove the pod and turn it upside down, remove the chimney unit and screw in your chosen coil. Replace the chimney unit with attached coil and reinsert into the pod. Push the pod back into the Aspire Nautilus AIO until it clicks. Note: when inserting a new coil and filling the pod, always let the device stand for 3 minutes to allow the coil to become saturated. This will help avoid dry hits and damage to the coil. Refilling the pod is super easy. Remove the pod from the device by squeezing the two side buttons, invert the pod and remove the silicone plug from the 4.6 diameter filling hole. Fill the pod with e-liquid, and replace the silicone plug securely. Replace the pod into the device by pushing down until it clicks into place, and it’s ready. Charging the Aspire Nautilus AIO is also very simple. Just plug in the supplied micro usb cable into the side of the mod, attach the other end to a suitable power supply to charge. The maximum charge current can reach up to 1A. When attached to the usb with the power on the LEDs will flash blue and orange three times, when fully charges the LEDs will flash blue and orange twenty times then remain off.
