The all new CF MOD from Aspire is a source of unmatched power supply pertaining to the low resistance atomizer. Convenient to use the CF MOD is compatible with the popular 18650 battery (which must be purchased separately), though it is not compatible with the USB charger offered by Aspire. Ideally designed to be used with low resistance atomizers as well as sub ohm tanks, the CF MOD is best suited for experienced vapers, owing to its high output range. The Aspire CF MOD comes with the unmatched advantage of letting you vape on the go since it allows you to carry more than one battery. Unlike other offerings from Aspire, the CF MOD doesn’t come with a variable voltage dial, and instead works directly at the maximum set limit of 4.2 volts at any given time. Please note that the CF MOD needs a third party charger.
