Three Jetson Orin Nano box PCs tie for the lowest listed maximum power draw, at 15 W each. Only 16 of the 106 Orin Nano box PCs in our catalog list a max power figure, so I can't rule out lower-power units among the other 90.

| Product | Maker | Max power | Power input | Operating temp | Cooling / IP rating | Weight |
|---|---|---|---|---|---|---|
| ATC 3520-IP7-3M | NEXCOM | 15 W | 9–36 V | -30 to 70 °C (depends on power mode) | Fanless / IP67 | 2400 g |
| ATC 3520-IP7-AI4CR | NEXCOM | 15 W | 24 V | -30 to 70 °C (depends on power mode and PoE load) | Fanless / IP67 | 3200 g |

How they differ for a solar build:
- ATC 3520-IP7-3M: its wide 9–36 V input may make it easier to run straight off a solar battery bank. It's also sealed to IP67, has 3 MIPI camera inputs and comes with 5G and GNSS. nexcom.com... +1nexcom.com.tw ↗“io.mipi_cameras=3”nexcom.com.tw ↗“connectivity.cellular=5G, connectivity.gnss_gps=True”
- ATC 3520-IP7-AI4CR: needs a fixed 24 V supply. It has 4 PoE ports with a 30 W PoE budget. If you power PoE cameras from it, expect the whole system to draw more than its own 15 W. nexcom.com +1nexcom.com ↗“io.poe_port_count=4”nexcom.com ↗“power.poe_total_budget_w=30 W”
- eNVP-JON-UB: the smallest and lightest of the three, with DIN-rail or wall mounting. It needs a fixed 12 V supply and has the narrowest temperature range (up to 50 °C), which matters in a sunny enclosure. everfocus...everfocus.com ↗“mechanical.mounting_type=DIN Rail, Wall Mount”
The next lowest are the NEXCOM ATC 3520-IP7-4C and EverFocus EAV-30N, both at 25 W. ai.nexcom... +1ai.nexcom.com ↗“power.max_power_consumption_w=25 W”everfocus.com ↗“power.max_power_consumption_w=25 W”
These are the makers' max power figures, not average draw. Your real daily energy use will depend on the Jetson power mode you set and what you connect to the box.
