The Arizer Solo Charger is designed specifically for the Solo vaporizer. This Solo Charger will also work with the Solo 2, however, you can expect a much slower charging time. This serves as a replacement if you misplace the charger that comes as a standard accessory to your vaporizer kit. You can also purchase this accessory if your charger is no longer working correctly. Of course, an extra charger will come handy in the future. The wall charger is made of high-grade plastic which is resistant to heat. The food-grade plastic is also classified as non-toxic, which makes it safe even if children are around.
