Key Features


Organized Cable Management

The Putnam 18-C Charging Station has a removable side panel to easily access power bricks. The Power Module is pre-fitted with elastic straps for holding your power bricks in place, while neatly routing cables through to each shelf and is removable and replaceable for future upgrades. To make life even easier, a pre-wired option is available with USB-C cables.**


Numbered Slots

By assigning each device it’s own slot number, it’s easy to know which devices are missing at the end of the day with only a quick glance inside the Charging Station.

Putnam 18 Organized Cables

Kiss Those Tangled Cords Goodbye

It’s virtually impossible to tangle the charging cables in the Putnam 18-C Charging Station. The cords are just the right length to reach each device–no more, no less, no mess. 


No Keys to Worry About

With an integrated mechanical combination lock, there are no keys to worry about. In the event of a forgotten combination, we’ve included a master override key.

Smarter Workflow

Save Time by Sharing Responsibility.
By assigning a numbered slot to every user, each user can take ownership of plugging in their device. All the teacher has to be responsible for is unlocking the station in the morning and locking it up at the end of the day.


Stackable Design. Larger classes can utilize two Putnam 18-C Charging Stations for a total of 36 slots. To save on space, stack them on top of one another–or if congestion around the station is your main concern, simply place multiple Putnams in different areas of the room to spread out the distribution of devices.

Product Benefits

Designed specifically for Chromebooks, small laptops or tablets up to 13”. The Putnam 18-C Charging Station can charge 18 devices simultaneously.

Slot dimensions are optimized to work with most cases and covers.

The tall, slim design of the Station is ultra compact, saving valuable real estate in space-strapped areas.

Set your own 4-digit PIN code on the mechanical combination lock and rest assured knowing the Station will keep your devices safe, organized and secure.

Putnam 18-C Charging Stations have an optional wall-mounting kit available (sold separately) that allows you to mount the unit directly to the wall.

An optional pedestal allows you to charge 36 devices (two stacked Stations) with one outlet plug. It is equipped with ECO Safe Charge, so you won’t have to worry about electrical overload while charging all 36 devices at one outlet. The pedestal also keeps a single-unit or stacked Station higher off the floor, which means you don’t have to bend down as far to access devices on the bottom shelves.

Welded and riveted steel construction and a built-in mechanical combination lock make this Charging Station ultra-secure. It’s also backed by a lifetime warranty worth writing home about.
