The following measurements provide reference figures for USB armory power consumption.
The measurements have been performed using an Agilent U1242B multimeter.
| Device | Idle¹ | Medium CPU+I/O workload | High CPU+I/O workload |
|---|---|---|---|
| Mk II - 900 MHz | 80 mA @ 5 V (400 mW) | 180 mA @ 5 V ( 900 mW) | 240 mA @ 5 V (1200 mW) |
| Mk II - 528 MHz | 70 mA @ 5 V (350 mW) | 140 mA @ 5 V ( 700 mW) | 170 mA @ 5 V ( 850 mW) |
| Mk I - 1 GHz | 110 mA @ 5 V (550 mW) | 270 mA @ 5 V (1350 mW) | 280 mA @ 5 V (1400 mW) |
| Mk I - 800 MHz | 110 mA @ 5 V (550 mW) | 250 mA @ 5 V (1250 mW) | 260 mA @ 5 V (1300 mW) |
¹ with frequency scaling and without power management (e.g. CPU suspend)
| Device | Idle² (@ 198 MHz) | Mixed CPU+I/O workload | High CPU+I/O workload |
