Why Wattsun Stack
With the Wattsun Stack, you create an inexhaustible, portable power source. Wherever you are. For professionals working in remote locations without access to the power grid, the Stack is the reliable energy solution. With the push of a button, you have immediate access to energy, even under varying (weather) conditions. Thanks to its robust casing, the Stack can withstand rough handling and always delivers maximum performance. Whether it’s for large events like Coldplay’s world tour, a small show at Oerol Festival and events by Awakenings, or construction companies like VolkerWessels, Heijmans, and rental company Boels—the Wattsun Stack has proven itself as the essential power source on-site.
The Wattsun Stack has been renewed: more power and capacity in the same compact casing.
The latest generation of Wattsun Docks and Packs offers more capacity and power in the same compact casing. Additionally, we’ve been able to fulfill various customer requests. You can now lift with one hand, charge with a built-in charger, use solar energy for charging, stack for charging, utilize an UPS backup function, and even work with the previous generation of Docks and Packs. Our engineers have succeeded in creating the best portable battery system on the market.
