The SPARK Power Unit SPU28b Multi-Interface Package includes both Right-Hand (RH) and Left-Hand (LH) aircraft interface modules—providing maximum compatibility across aircraft with different GPU receptacle orientations.
Designed for operators supporting multiple aircraft types, mixed fleets, or varying external power connector configurations, the Multi-Interface Package allows a single SPU28b platform to adapt quickly between aircraft without requiring separate dedicated power units.
Built around the same high-performance architecture as every SPU28b, the system delivers class-leading starting capability in the smallest and lightest package in its class, while maintaining the flexibility demanded by real-world aviation operations.
Included in the Operator Package
✔ SPU28b Power Unit
✔ Right-Hand (RH) Aircraft Interface
✔ Left-Hand (LH) Aircraft Interface
✔ Charger & 110V AC Adapter
✔ Interface Protection

Have room for all of your gear with the smallest power unit on the market, the SPU28b
Smallest in Class
Most portable aircraft power units are designed around battery capacity—increasing amp-hours to meet mission requirements. The result is often larger, heavier systems that still struggle to maintain strong starting performance as battery charge decreases.
The SPARK Power Unit takes a different approach.
Lightest in class
Rather than relying on sheer battery size, the SPU28b is engineered around high discharge capability—delivering exceptional starting power from a significantly smaller and lighter package.
How do we do it?
Traditional systems commonly provide continuous discharge rates around 20× battery capacity, meaning available output decreases substantially as state-of-charge drops. As the battery drains, starting performance can quickly diminish.
The SPU28b is engineered to deliver up to 600A continuous discharge, maintaining strong starting capability even at reduced state-of-charge. This allows operators to achieve more starts, greater operational flexibility, and higher power output without the size and weight penalties of conventional units.
More usable power. More starts. Less weight.
Here's the best part
SureStart
Operational Readiness, Protected
SureStart is an intelligent reserve power protection system designed specifically for real-world aircraft operations. Unlike conventional low voltage cutoffs that only react when a battery is nearly depleted, SureStart dynamically protects starting capability during low-current usage such as fuel pumps, avionics, lighting, or ground preparation.
If the unit is accidentally left connected or forgotten during preflight operations, SureStart intervenes early enough to preserve sufficient state of charge for your next start, helping ensure the SPU28b is ready when the aircraft is.
DualCore Start Redundancy
Because Critical Systems Deserve Redundancy
The SPU28b incorporates a dual-path parallel battery architecture designed to maintain starting capability even in the extremely unlikely event of an internal fault during engine start.
Modular Construction
Built to Adapt
The SPU28b was engineered around a modular architecture that allows the system to be configured for a wide range of aircraft interfaces and operational requirements.
Its adaptable attachment-based design currently supports multiple aircraft connection configurations while providing a flexible foundation for future expansion and mission-specific capability integration.
