The OE1 Workspace Collection from Herman Miller features workspace essentials designed for agility and an evolving future. The OE1 Power Pack and Power Tray allow you to bring power wherever it's needed most. Each mobile battery has three USB-C ports and one USB-A port that can easily be shared at a communal table. When not in use, the Power Tray ensures the batteries stay charged. When holding the batteries, the Power Tray can also charge larger devices like a display. Best of all, the batteries are recyclable, making them less hazardous to the environment.
