Tech the Halls With Agency-Specific Gifts

Energy

• People at the Energy Department can save power and charge their devices on the go with the Gearonic waterproof solar-powered cellphone charger. The device can charge a smartphone up to four times, and has a snap hook that can easily attach to a backpack.

Homeland Security

• DHS agents, particularly those who patrol the borders, may appreciate the DJI Phantom Drone 4. This newest model has longer legs to ensure for a safe landing and a battery that lasts 28 minutes. In “sport mode,” it can travel 45 mph.

Agriculture

• USDA employees, especially those who spend time in the field, can use the GreenSeeker crop sensing system to make sure their crops have enough nutrients. The device, which is mounted on fertilizer spreaders, uses optical sensors to assess crop health. The optical sensors can function at nighttime and in cloudy weather.
