Device

Types of Devices
There is quite a wide variety of items that fall under the Device category. There are Crafting Stations, Power Generation Stations, Power Storage Stations, Personal Utility Devices and more.

Crafting Devices
Some crafting Devices such as the Combinator and Furnace do not require any power to operate, the Combinator itself actually generates a small amount of power.

The others such as the Workbench or the Smelter and most of the other require that you power them before they become usable. Initially you will need to power your Workbench by placing a Socket and running a cable from the Combinator to the Socket and then another cable to the Workbench.

Once this is done you can begin progressing towards more advanced crafting stations.

Power Generation Devices
There are a number of devices that are used to generate Power for your base. The Power Generator is the first that you will create. Once placed and turned on connect it to your Base's wiring and it will help power everything connected to that wiring system. There are more advanced generators further into the game.

Power Storage Devices
There are a few items as well as an Energy Storage Bank That will either store power or provide power for your Personal utility items.

Battery and Anti-Matter can be used as Ammo for the Laser Gun, as well as can be put into your Accessory slots for power your Suits, Weapons built in Flashlights. Careful as Death will drain half of whatever available power is in your Battery.

The Power Gauge will allow you to monitor your current power on hand, you generation and your usage.

Personal Utility Devices
There are a few Devices that I would further categorize as Personal Utility. There are the Booster Boots that will allow for a double jump to gain additional height. These should only activate on the downward arc of your first jump.

The Jetpack allows for sustained flight but also requires Fuel. Carefull bumping your head on things hurts. Having a Fuel Tank in you inventory is important as the Jetpack will automatically refuel itself with the available Fuel.

There are a few other devices that fall into this category as well, the Re-Breather and the Aqua-Pack can be quite useful as well.

Crafting Materials
There are a few other devices in this category that only serve as materials to create more complex devices, such as the Pressure Casing. Some of these such as the Spark Plug can only be found by salvaging Scrap found around the world, or in Event Chests that spawn randomly.

Wiring and Electrical
There are a few devices that are used to provide power to your various crafting stations and lights. The Socket while actually in the Building category will allow for multiple branching wire connections so as to power multiple devices and Lights.

The Wire Pole allows for longer cable runs without having to bury the wire or place wall tiles. Pretty much your standard Power pole.

Various switches will allow for cutting power to certain Lights or stations the Wall Switch is just one of them.
