With the Wahl super taper cordless prolithium clipper it is possible to use it without and with a cord. The Lithium Ion battery charges the clipper within 120 minutes, so you can use it for 90 minutes.
The super taper cordless prolithium is lighter and narrower, making it more comfortable in the hand and more comfortable than other clippers.
Note: Make sure the clipper is properly maintained to significantly extend the life of the device. Therefore, use a drop of Wahl oil before and after each shave to lubricate the blades.
