Whether you’re preparing for a preflight inspection, powering up avionics for software updates, or performing multiple engine starts between flights, having a dependable ground power source can make or break your workflow. The StartStick is a portable, lithium-ion ground power unit (GPU) designed to deliver high-performance aircraft starts and avionics support in a lightweight, compact form factor.
Trusted by civilian, military, and commercial operators worldwide, the StartStick enables pilots and maintenance crews to reduce turnaround times and increase operational efficiency. Its rugged build, aircraft-specific compatibility, and ability to deliver significant starting power make it a go-to tool for operations both on and off the grid. In this article, we’ll explore how the StartStick works, what sets the different models apart, and why this innovative GPU continues to earn its place in hangars and cockpits across the industry.
What Is the StartStick, and Why Do Pilots Use It?
The StartStick is a compact, battery-powered ground power unit that delivers instant 28V DC power to start aircraft engines and support onboard electronics. Unlike traditional cart-based GPUs, which are heavy and immobile, the StartStick offers aviation professionals a lightweight, portable alternative that can be carried easily to and from the aircraft. It provides high cranking amps through lithium-ion battery technology, making it ideal for quick, off-grid starts or powering avionics systems during ground operations.
Pilots and ground crews rely on the StartStick for its combination of reliability, convenience, and ruggedness. Designed for both fixed-wing and rotary-wing aircraft, the StartStick has become an essential piece of ground support equipment (GSE) in both civil and military environments. It eliminates the need for long extension cords or bulky external power sources, helping crews stay flexible and responsive, even in remote locations.
How Does the StartStick Work?
The StartStick delivers a high-current DC output through a connector specific to your aircraft model. It draws energy from its internal lithium-ion cells, which are engineered to provide short bursts of high power for engine starts or sustained output for avionics support. The unit connects directly to the aircraft’s external power receptacle using a standard aviation connector, such as a Piper, Cessna, or NATO plug.
Built-in safety features include reverse-polarity protection, overcurrent protection, and electronic voltage regulation to protect both the aircraft and the unit. When it’s not in use, the StartStick can be recharged via AC or DC power sources using the included charger or vehicle charging adapter. Thanks to its simple interface, pilots and technicians can operate the StartStick confidently with minimal training.
What Types of Aircraft Can the StartStick Be Used With?
The StartStick is compatible with a wide range of piston, turboprop, and light turbine aircraft. This includes popular general aviation models from Cessna, Piper, Beechcraft, and Cirrus, as well as select helicopters and military aircraft. The key is to match the StartStick to the aircraft's correct connector and power requirements, which is made easy by the unit’s modular cable system.
Fixed-wing aircraft benefit from the StartStick’s ability to perform cold starts and support avionics checks on the ramp or in the hangar. Rotorcraft operators appreciate its compact size and rapid-start capabilities, especially in remote landing zones or when ground power isn’t readily available. With more than 3,000 units deployed globally since 2014, the StartStick has been proven in diverse conditions – from busy airfields to isolated military outposts.
What Are the Differences Between the StartStick 10Ah, 15Ah, and 20Ah Models?
The StartStick lineup includes three models – 10Ah, 15Ah, and 20Ah – each tailored to specific mission requirements. The 10Ah model is the lightest at just 9 pounds, making it a top choice for pilots who prioritize portability and only need a handful of starts per charge. It’s well-suited for piston aircraft and light turbine aircraft with lower start-power requirements.
The 15Ah version offers a solid middle ground, providing more starts per charge (up to 10 for certain aircraft types) while remaining lightweight and easy to carry. It features a durable, MIL-SPEC, fully sealed housing with G-shock protection – ideal for fleet operators and flight schools that need frequent starts and continuous avionics power throughout the day.
For larger aircraft or more demanding operational environments, the 20Ah model delivers maximum capacity and performance. It can support up to 15 turbine starts under optimal conditions and provides longer-lasting avionics power. At around 16 pounds, it offers the most energy of any StartStick while maintaining portability. All three models are fully refurbishable, giving operators a cost-effective way to extend the life of their investment.
How Many Engine Starts Can I Expect from a Single Charge?
The number of engine starts you’ll get from a single charge depends on several factors, including the aircraft’s power requirements, the ambient temperature, and the specific StartStick model. On average, the 10Ah StartStick delivers 3 to 4 starts per charge, including for turbine helicopters. The 15Ah model can deliver up to 10 piston starts or 3 to 5 turbine starts under standard conditions.
The 20Ah version offers the most flexibility, supporting 8 to 15 turbine starts per charge depending on engine type and temperature. Pilots operating in colder climates or starting larger engines may notice a slight reduction in performance, but overall, the StartStick is known for its reliable, repeatable output. Using more than one unit can further extend starting capacity or support rapid turnaround operations.
How Long Does It Take to Recharge the StartStick?
Charging times vary by model and power source, but all StartStick units are designed to recharge efficiently between missions. Using the standard AC charger, the 10Ah model takes approximately three hours to fully recharge, while the 15Ah and 20Ah models may take closer to four to six hours, depending on the level of discharge.
The StartStick also comes with a DC charging cable, allowing it to be recharged in a vehicle or aircraft with a compatible power outlet. This makes it easy to top off between flights or during transport. Operators who need continuous access to GPU power may consider using a second fully charged StartStick for backup while the other recharges.
Can I Use the StartStick to Power My Avionics on the Ground?
Yes, the StartStick functions not only as a starting battery but also as an external power source for cockpit systems. It’s especially useful for powering up avionics, radios, GPS units, and other electronics during preflight inspections, system checks, and software updates. This allows pilots and maintenance crews to perform critical tasks without drawing down the aircraft’s main battery.
Using a portable GPU like the StartStick reduces wear on onboard electrical systems and provides a safer, more controlled environment for avionics testing. It also prevents unnecessary engine starts, helping operators save on fuel and reduce emissions. With adjustable output and secure connections, the StartStick is well-suited for ground-based operations of all kinds.
How Long Can the StartStick Power My Aircraft Systems?
Avionics runtime depends on the specific StartStick model and the electrical load of the connected systems. On average, the 10Ah StartStick can power basic avionics for 20 to 30 minutes, while the 15Ah version extends that to around 45 minutes to an hour. The 20Ah model offers the longest runtime, often exceeding 90 minutes under moderate electrical loads.
Factors that affect runtime include the number and types of devices being powered, ambient temperature, and the battery's health. Operators conducting prolonged diagnostics or updates may benefit from keeping a second unit on standby or cycling between two units to maintain continuous power.
What Accessories Are Available for the StartStick?
A range of StartStick accessories is available to improve how you protect, transport, and use your portable GPU. Lightweight stowage bags tailored for each model – the 10Ah, 15Ah, and 20Ah – offer quick access and easy carry options on the ramp or in the hangar.
Additional accessories include a 3-foot extension cable for more flexible GPU-to-aircraft connections, a strain relief kit to protect the power lead from wear, and a replacement wall charger for safe, efficient battery recharging. These thoughtfully engineered add-ons help you customize your setup for greater convenience, protection, and charging flexibility. Like the StartStick itself, each accessory is built for durability and ease of use in demanding aviation environments.
