The USBKill has evolved beyond a simple plug-and-zap device. The new V4 hardware framework enables advanced functionality and performance.

Aside from more powerful discharges and improved stability, the V4 has an internal, rechargeable battery, which allows for "Offline Attacks" - where the host device is not turned on.

"Offline Mode" also bypasses all known USB-C and Lightning (Apple/iPhone) security protocols, rendering the V4 the ultimate device for testing smartphones and modern hardware.
