Product Overview

Custom Sheet Metal Enclosure for Portable Power Station

This custom sheet metal enclosure is designed for portable power stations, battery discharge management units and energy storage devices. Fabricated from 6061 aluminum plate with a sand-blasted anodized finish, the housing is lightweight, rigid and corrosion-resistant — ideal for mobile power equipment.

The front panel is laser-cut to match your interface — an LCD display window, household and professional AC outlets, USB and Type-C ports and switches. Ventilation grilles and louvers keep power electronics cool under continuous load. The matte anodized surface resists scratches, and silkscreen printing marks ratings and your brand. We supply fully custom enclosures from a single prototype to production runs.

😩 Typical Buyer Pain Points
