This power adapter is intended to be used with the Arizer Solo. It works with the Arizer Solo 2 as well, but it charges slower. The power adapter for Arizer Solo does not come with the vaporizer as a standard accessory. However, it is an official Arizer part and is a great tool for anyone who vapes at home. With this adapter for Arizer Solo, you can power your vaporizer directly from the A/C power source. This will let you vape even if your Solo has no battery life. The Arizer Solo Power Adapter alone will not charge your unit. You will need the Arizer Solo Wall Charger for that.
