Argus USBP — External NVG Power, Built-In IR Strobes, Helmet Counterweight
External NVG power. Built-in IR strobes. Helmet counterweight. Three problems solved by one piece of kit.
Order NowOne Mount. Three Capabilities.
Your NVGs run on onboard batteries. The USBP adds an external power source via Fischer port that extends your runtime — and mounts on the back of your helmet to counterbalance the weight of your goggles up front. Less neck strain over a long operation. Two IR strobes built into the pack for IFF and SAR signaling. One accessory. Three distinct capabilities.
The Counterweight Advantage
NVGs are front-heavy. Over hours of sustained wear, that lever arm beats up your neck. The USBP mounts on the back of the helmet, shifting the balance point and reducing cumulative fatigue. This is a real performance factor on long operations, not a minor comfort improvement.
Extended Runtime via Fischer Port
Connects directly to any NVG with a Fischer-compatible port. The smart voltage regulation circuit stabilizes output regardless of battery charge state, so your device gets clean power from full battery down to nearly dead. No voltage spikes. No unexpected shutoffs.
IFF and SAR Strobes Built In
Two powerful IR strobes are integrated into the housing. Visible to other NV users and airborne assets. Use them for unit identification, search and rescue signaling, or marking position for friendly aviation. The strobes continue operating even at critically low battery levels — when you need them most.
Three Capabilities. One Mount Point.
Most accessories solve one problem. The USBP solves three — extended NVG power, helmet balance, and IR identification — from a single helmet-mounted unit running on AA batteries available anywhere on earth. IP67 sealed. Fire-resistant polymer casing rated for harsh environments. Circuit protection against short circuit and voltage spikes. This is a well-engineered piece of kit at a price that makes it a straightforward add to any serious NVG setup.
How External NVG Power Works — And Why It Matters
Most NVGs are powered by a single onboard battery — the PVS-14, for example, runs on one AA cell in a compartment at the back of the housing. Under normal conditions that battery delivers several hours of runtime. Under cold conditions, at high draw (with an IR illuminator running), or on extended operations, that runtime shrinks. Running out of NVG power in the middle of a night operation is not a theoretical concern — it is a documented logistics problem that every unit using NVGs has encountered.
External power solves this by bypassing the onboard battery entirely. The Fischer port — the standard external power interface on the PVS-14 and most mil-spec NVGs — accepts a cable from an external battery pack and feeds power directly into the device's voltage regulation circuit. The NVG runs off the external source as long as it has power; when the external source is exhausted, the device automatically falls back to the onboard battery. This gives you predictable, extended runtime without any operator intervention — and the ability to hot-swap the external pack without powering down the device.
Voltage regulation matters because batteries do not deliver constant voltage. A fresh AA cell provides close to 1.5V. At half discharge, it is closer to 1.2V. At near-exhaustion, lower still. NVG image intensifier tubes are sensitive to voltage variation — a tube that gets stable, regulated voltage will perform more consistently than one experiencing voltage sag as the battery runs down. The USBP's regulation circuit maintains clean, stable output across the full battery discharge range. Your NVG image quality does not drift as the pack ages through its charge cycle.
The counterweight function is a separate benefit that compounds over time. A PVS-14 monocular weighs roughly 390g. A binocular NVG system can run 600–900g depending on configuration. All of that weight sits in front of your helmet's mounting point, creating a forward moment arm that your neck muscles resist continuously. Over hours of sustained wear, this cumulative load causes real fatigue — first in the neck, then in the shoulders. Moving the USBP to the rear of the helmet shifts enough weight rearward to meaningfully reduce that moment arm. The performance benefit is most apparent on multi-hour operations where fatigue would otherwise be compounding.

Argus USBP — Frequently Asked Questions
What is the Argus USBP?
The Argus USBP is an external NVG power source, dual IR strobe, and helmet counterweight in a single rear-helmet-mounted unit. It connects to your night vision device via Fischer port, providing extended runtime beyond the device's onboard battery. Two IR strobes handle IFF and SAR signaling. Running on standard AA batteries, it mounts to the rear of your helmet and counterbalances the forward weight of your NVG system. Price: $280.
What NVGs is the Argus USBP compatible with?
The USBP connects via Fischer port, which is the standard external power interface on PVS-14s, binocular NVGs, and most mil-spec night vision systems. Adapter cables are available for devices with different port configurations. Contact Adams Industries to confirm compatibility with your specific NVG before ordering.
Why does the counterweight matter?
Night vision devices are front-heavy, and over hours of sustained helmet wear, that forward weight creates cumulative neck fatigue. The USBP mounts to the rear of the helmet, shifting the center of gravity toward balance. On a short operation this is a minor comfort factor. On an 8-hour sustained wear evolution — a long SAR operation, a night vehicle convoy, a multi-hour security operation — it is a genuine performance factor. Operators who have worn NVGs for extended periods without counterweight, then switched to a counterweighted setup, consistently report the difference as significant.
How do the IR strobes work?
The two built-in IR strobes are high-powered infrared emitters visible through night vision devices and to airborne IR sensors. They are used for IFF — identifying your unit's position to other NV-equipped users or aircraft — or for SAR signaling to mark a position for aerial assets. The strobes are designed to continue operating at critically low battery levels, when external power capability may be reduced. They can also be operated standalone without an NVG connected.
What batteries does the USBP use?
The USBP runs on standard AA batteries. Lithium AA (L91) is strongly recommended for maximum output and cold-weather performance. The voltage regulation circuit maintains stable output across the full discharge curve — your NVG gets clean power until the batteries are nearly exhausted, without voltage sag. Do not use NiMH rechargeable AA cells in NVG applications — they deliver insufficient voltage at cold temperatures and can cause device shutoffs.
Is the Argus USBP waterproof?
Yes — IP67 rated, meaning complete protection against dust and temporary immersion in water to 1 meter for 30 minutes. The casing is fire-resistant polymer with additional short-circuit and high-voltage impulse protection built into the circuit. The USBP is designed for operational field use in adverse conditions, not just dry-weather use.
