Quick verdict

BossHorn’s Quad Train Horn for Craftsman® 20V Battery is the upper of the two BossHorn models sold for the Craftsman 20V battery platform. It’s a pre-assembled handheld horn with four powder-coated aluminum-alloy trumpets, a wireless remote, and a $250 price for Black ($270 for Chrome or Red). The spec disclosure is better than most portable sellers manage: dimensions, weight, runtime, remote frequency, and protection thresholds are all published. We rate it 4.0/5. It loses points because the same page lists its loudness as both 140 dB and 150 dB with no test distance, its remote range as both 160 ft and 300 ft, and its 500+ blast runtime against both a 2Ah and a 6Ah pack. In our editorial opinion it’s a sensible buy if you already own Craftsman 20V batteries, as long as you treat the numbers as marketing claims.

What it is

The Quad is a fully assembled, handheld train horn that runs on any Craftsman® 20V battery from 2.0Ah to 12.0Ah. BossHorn’s spec table says aftermarket 20V-compatible packs work too. A traditional air kit chains a compressor, tank, and solenoid. Here, an onboard electric compressor feeds four trumpets in graduated lengths: one 14”, one 12”, one 8”, and one 5”. BossHorn’s spec table calls the sound a “freight train horn deep low tone,” while the trumpet selector on the same page labels the Quad “medium pitch.”

BossHorn says it ships pre-built as “a complete tool, not a kit.” You insert a charged battery, then press the trigger or the included wireless remote. The seller pitches it for tailgates, sporting events, boating, off-road trips, job-site shift signals, and wildlife deterrence. It isn’t sold as a replacement for a vehicle’s wired horn. The page carries a disclaimer that BossHorn is made by Horngun Corp. and is not affiliated with Stanley Black & Decker, which owns the Craftsman® trademark.

BossHorn’s Craftsman collection has two models. One is this Quad. The other is a cheaper Dual Train Horn for Craftsman® 20V Battery at $195 (Black) or $215 (Chrome/Red), which the page lists at 130 dB with two high-pitch trumpets. The Milwaukee®, DeWalt®, and Makita® battery platforms also get an Extreme Series tier. Craftsman doesn’t, so the Quad is the most powerful option on this battery system.

In our editorial view it suits three kinds of buyers:

• Homeowners and DIYers who already have Craftsman 20V packs from their other cordless tools
• Truck, Jeep, and boat owners who want train-horn volume without drilling, wiring, or air lines
• Event users, from youth-sports parents to tailgaters, who want a loud signal with zero setup

What’s in the box

• 1× Quad train horn, fully assembled (four trumpets, compressor, pre-wired harness)
• 1× Wireless remote control (160 ft rated), with its battery included

No Craftsman 20V battery or charger is included. BossHorn sells a 2Ah 20V-compatible battery (rated by BossHorn at 200+ blasts per charge) and a 20V-compatible fast charger as $30 add-ons each. Extra standard remotes are $35, and a 2,000 ft long-range remote is $59. On Horngun, the same unit lists at $210 Tool Only. A $270 Tool + Battery option was showing as sold out when we checked. BossHorn’s warranty covers the horn unit only, not batteries or chargers.

Pros

• Zero installation: snap in a charged Craftsman 20V battery and it’s ready, with no tank, air lines, or relay wiring
• Four graduated aluminum trumpets (14”/12”/8”/5”) for a layered chord rather than a single flat note
• Detailed spec disclosure for a portable unit, including dimensions, 4 lb weight, runtime, remote frequency, and protection thresholds
• Battery-side safeguards: 15% discharge cutoff, 185°F motor shut-off, and an LED low-battery indicator
• Bigger review sample than most BossHorn listings: 20 on-site reviews averaging 4.95, with buyers repeatedly describing the sound as loud and deep
• 1-year full warranty, 90-day money-back window, and free US shipping

Cons

• Loudness is listed as both 140 dB and 150 dB on the same page, with no published test distance for either
• Remote range appears as 160 ft and 300 ft, and the 500+ blast runtime is tied to a 2Ah pack in one place and a 6Ah pack in another
• Battery and charger not included, so budget about $60 more from BossHorn if you don’t already own Craftsman 20V packs
• No trigger lock: one reviewer wished it kept a locking mechanism to prevent accidental blasts while carrying
• No Extreme Series tier for Craftsman batteries, so this 140 dB-rated Quad is the ceiling on this platform
• Seller-hosted ratings only, and no independent sound measurements we could find

Alternatives

• BossHorn Dual Train Horn for Craftsman® 20V Battery: the cheaper, lighter-sounding sibling on the same battery, with two high-pitch trumpets rated at 130 dB for $195. We haven’t reviewed it yet; see the BossHorn brand hub for the models we have covered.
• BossHorn DeWalt-compatible Quad Train Horn (20V): the same four-trumpet format for DeWalt® 20V MAX battery owners, with Dual and Extreme tiers on either side of it. See our DeWalt-compatible Quad review.
• BossHorn Milwaukee-compatible Quad Train Horn (M18): the same quad concept built around Milwaukee® M18™ batteries. See our Milwaukee-compatible Quad review.

For a truck-mounted setup instead of a handheld one, a 12V air kit like the one in our Kleinn HK4 review is the permanent route. The portable battery train horn guide compares the handheld format across brands, and our air vs battery guide helps if you’re still choosing between the two.

Install / compatibility notes

There’s no install in the traditional sense, which is the whole pitch. Things worth knowing before you buy:

1. Battery platform: any Craftsman® 20V pack from 2.0Ah to 12.0Ah, and BossHorn says aftermarket 20V-compatible batteries work too. The page ties 500+ short blasts to a 6Ah pack in the spec table and to a 2Ah pack in the FAQ. Plan around the more conservative reading: BossHorn’s own 2Ah add-on is rated at 200+ blasts.
2. ”20V” doesn’t mean cross-brand: the battery has to match the Craftsman 20V slide-in interface. A 20V pack from another tool brand won’t fit unless it’s sold as Craftsman 20V-compatible. Our battery platform comparison explains why voltage labels alone don’t guarantee fit.
3. No vehicle wiring: nothing connects to your vehicle’s 12V system. If you want a horn on the steering-wheel button, you need a wired air kit.
4. Carry and storage: BossHorn recommends removing the battery when stored to prevent accidental activation. Given the reviewer comment about the missing trigger lock, we’d also pull the pack before carrying it through a crowd.
5. Weather exposure: the body is rated splash-resistant, not waterproof. BossHorn says not to submerge it and to store it indoors in a cool, dry place.
6. Duty cycle: BossHorn advises short breaks during extended continuous use, and the motor cuts out at 185°F. If a long blast stops on its own, that’s the protection working.
7. Remote planning: because the page lists both 160 ft and 300 ft, assume 160 ft where reliability matters, or budget $59 for the 2,000 ft remote. BossHorn says multiple remotes can be used at the same time.
8. Hearing safety: BossHorn’s FAQ recommends hearing protection at close range and says full power is for outdoor use only. See our hearing damage guide and decibel guide.

On user feedback: when we checked, BossHorn’s product page showed a 4.95 average across 20 reviews (19 five-star, one four-star), while a stats banner further down the same page showed 4.9 stars. Several reviewers mention already owning Craftsman 20V tools, and one says it outperformed similar-looking horns at a 10U state championship. These are seller-hosted reviews, so we treat them as a positive signal, not independent verification.

One small inconsistency: the shipping section gives a 12:00 PM PST same-day cutoff, while the FAQ says 2 PM PST. Order before noon Pacific if timing matters.

Legality is on the user. BossHorn’s FAQ says the horn is legal to own and use on private property in all 50 states and that road or vehicle use varies by state. A handheld horn sidesteps the equipment rules for installed vehicle horns in many states, but blasting it in public can still run into local noise ordinances. Check our state legality pages and city noise ordinance guide before using it in town. For how a quad chord compares with dual and single setups, see single vs dual vs quad trumpets.
