Jump-Starting a HUMVEE or MRAP Without a Slave Cable

Anyone who has jump-started a tactical vehicle with the standard slave/jumper cable (NSN 10502786) knows the drill: get a second vehicle, position it nose-to-nose or close enough to run the cable, connect it under the hood or through the access panel, and keep at least one soldier exposed outside both vehicles for the duration of the connection. It works — it's been the standard procedure for decades — but it needs a second running vehicle, multiple personnel, and time none of them get back if the position isn't secure.

What the Slave-Cable Method Actually Requires

• A second vehicle, running, positioned close enough to connect the cable
• Typically 4 or more personnel to position vehicles, route the cable, and manage the connection
• At least one person outside the vehicle armor during the entire connection and disconnection
• A stationary window in which both vehicles are non-mobile and exposed

In a training environment that's an inconvenience. In a contested or forward environment, every one of those requirements — a second asset committed, personnel outside armor, a fixed exposure window — is a real operational cost, independent of how simple the actual electrical task is.

The Single-Soldier Alternative

The StartStick Military Ground Vehicle GPU is a portable, self-contained battery pack purpose-built to replace that slave-cable procedure. One soldier connects it directly to the vehicle's NATO-style DC receptacle and starts the engine — no second vehicle, no cable routing, no one stationed outside the armor waiting on a connection. At 9.2 kg (20.2 lbs) and roughly the size of a large tool case, it's carried in the vehicle itself rather than staged separately.

Compatible Platforms

StartStick's military variant is built to work across any ground platform with a compatible DC power receptacle — HUMVEE, MRAP, M1A1 Abrams, and equipment as varied as bulldozers. It isn't a single-vehicle accessory; it's a general-purpose replacement for the slave-cable procedure fleet-wide.

Purpose-Built Kits

• MRAP NATO Relocation Kit — adds a second NATO DC receptacle so the connection can be made from inside the vehicle rather than externally.
• HUMVEE Relocation Kit — relocates the NATO DC receptacle for the same inside-vehicle access.
• HUMVEE M134D Turret Mount Kit — engineered specifically to power the M134D weapon system from the same StartStick platform.

The relocation kits matter as much as the GPU itself: they're what take the "no exposure outside the vehicle" advantage from theoretical to actual, by removing the need to open a hood or access panel to make the connection at all.

Why This Replaces a Depot Battery Cart, Too

Beyond the slave-cable comparison, StartStick's rated 3,000–4,000 starts per pack life is the reason units are also displacing heavier depot battery carts for routine engine starts — a sealed, portable pack that outlasts the interval on a conventional lead-acid ground support battery, without the cart's bulk or maintenance overhead.
