Hair clipper Adler 2827 offers you professional and precise hair cutting with the help of a ceramic blade. Efficient batteries allow for a few hours of use, but it can also be operated with a cord. The hair clipper can be charged with a charger or docking station. Additionally, the clipper is equipped with four different comb attachments: 3 mm, 6 mm, 9 mm, and 12 mm. Please note that there is only one battery inside the device; the mention of two batteries on the box is a printing mistake. We apologize for any inconvenience.
