Remove a cork in seconds with the push of a button—no pulling or forcing required. Made with a lithium-ion battery that offers a longer life and slower self-discharge when not in use, compared to other rechargeable batteries. The included micro-USB charging cable allows for charging almost anywhere. Built-in blue LED lights illuminate when charging and in use, and the sleek brushed stainless steel body with a smoked black viewing window looks great in any environment.
