“Vuse Alto brand has their own rechargeable power unit for the use of their specially designed disposable pods sold separately unless the box is labeled with the all included kit. These power units include 1 rechargeable stick (pods sold separately) & 1 charging cable designed to fit the battery stick. There are different colors to choose from. The charging cable has a usb end that’s designed to fit your standard block plug. The other end is shaped to fit the unit itself. When your unit needs charging it will flash the green light several times indicating it is dying. Simply remove the pod from the unit to protect the quality of taste and put the unit end into the magnetic holder of the cord. Plug the cord into a usb port plug and it will light up green while charging. Once the unit has been fully charged the green light indicator will turn off. Remove unit from the cord, pop in the pod and continue vaping. Please note: I have noticed by leaving the vaping pod in the unit while charging it tends to change the flavor of the pod giving it a burnt taste. But the option to remove while it's charging is completely yours.”
