The SilentPower iDefender Max sits between a computer and a USB device to suppress noise carried by USB power. It cuts the PC's noisy power and replaces it via a USB-C port with clean external power—for example, an iFi iPower 2. Audio clarity improves.

The iDefender Max automatically detects and interrupts ground loops that cause hum, without compromising safety. IsoGround technology intelligently lifts the ground reference and directs excess current to earth rather than to connected devices.

USB 3.0 and USB 2.0 compatible, the iDefender Max ensures fast data transfer and passes up to 100 W (20 V/5 A). It suits USB DACs, audio interfaces, microphones, and USB speakers, delivering high-resolution files without latency.

The aluminum housing ensures longevity, acts as a heat sink, and shields against electromagnetic interference. Dimensions: 5.1 × 2.0 × 1.2 cm, 21 grams.
