The Problem

You've Been Solving One Problem With Two Devices.

Every person who brings a portable power station outdoors also brings a speaker. Always. The two leave together, come back together, charge from the same panel, take up the same bag.

$650–$1,100+
Combined cost of a quality power station + quality speaker. Two products that always go to the same place.

Two devices. Two cables. Two warranties. Two companies to call when something breaks. One problem that always needed one solution.

We Built the Device They Should Have Built and Didn't.

Category Definition

Introducing the
Power Boombox.

Not a speaker. Not a power station. Both — engineered as one system. The people who need portable power and portable audio are the same people. They go to the same places. PowerJam defined a new category to solve their problem.

⚡
Full Power
LiFePO4 battery. 120V AC pure sine wave. USB-C PD. 12V DC. Solar input. A complete portable power system.
🔊
Full Audio
RMS-rated output. Full-range drivers. Passive radiator bass. Bluetooth 5.0 + aptX. Engineered for outdoors, not a living room.
🛡
Built Rugged
IP65 weatherproof. Drop-tested construction. Cold-weather rated. One enclosure for real-world conditions.
What's Inside

Built for the Decade.
Not the Product Cycle.

Every spec exists for a reason. No filler.

⚡
LiFePO4 — 2,000+ Cycles
Li-ion NMC starts declining after ~500 cycles — 17 months of daily use. LiFePO4 delivers 4× the lifespan and is thermally stable to 518°F. The only chemistry we build with.
🔌
120V AC — Pure Sine Wave
Not modified sine. Pure sine wave — safe for CPAPs, laptops, power tool chargers, and any load that rejects a dirty waveform. What comes out of your wall.
💻
USB-C PD 60W+
Fast-charges laptops, tablets, and phones simultaneously without a brick. Full rated speed. The port that keeps a MacBook Pro alive through a full field day.
📊
RMS-Rated Audio
Peak watts is what budget brands advertise. RMS is the sustained output the speaker delivers all day without distortion. It's the only number that matters. We publish it.
🔉
Passive Radiator Bass
Full-range woofer + tweeter array with passive radiator. Bass you feel at a jobsite or campsite. Not just bass that registers in a quiet room with the volume low.
☀️
Solar Input + Pass-Through
Compatible with 100W–400W panels. Charges while you draw power. Show up with a full unit. Leave with a full unit. True off-grid system, not a weekend battery.

Use Cases

PowerJam Works
Where You Work.

Which is everywhere the grid isn't.

🏗️
The Jobsite
Charges tool batteries, keeps phones live, runs audio all day, powers a work light after sundown. No generator noise. No dead speaker at 2pm. One unit on the tailgate.
🛻
Overlanding + Camping
Solar charges while you drive. Runs audio, lighting, and device charging all evening. Recharges the next morning off the panel. One carry handle. Zero generator fumes.
🏈
Tailgating
Run the cooler fan. Charge the phones. Play the game all day. No shore power, no exhaust at the grill, no engine noise. PowerJam runs silently and plays music simultaneously.
🚨
Emergency Prep
Runs a fan, charges medical equipment, powers communications, and plays music during a prolonged outage. Solar-recharges every day the sun rises.
🎪
Festivals + Events
One bag instead of two. Solar-charge during the day. Full battery, full volume by nightfall. The choice between power and music is permanently eliminated.
🏪
Small Business
Food trucks, pop-up shops, market vendors. Runs POS, lighting, and audio all day. No generator exhaust at the service window. No engine noise interrupting the sale.
From the Field

What It Does in the Real World.

★★★★★

"I used to show up to every job with a backpack just for the speaker and charger. Now it's one unit on the tailgate. PowerJam charges everything, plays all day, and I haven't thought about it once since I set it up. That's the highest compliment I know how to give a piece of gear."

🏗️
Mike R.
Framing Contractor
★★★★★

"Ran PowerJam off a 200-watt panel for six days straight in the backcountry. Never plugged into the grid. Audio was loud enough that the next campsite asked what we were running. Told them. They ordered one before we broke camp."

🛻
Jason T.
Overlander
★★★★★

"When the power went out for five days after the storm, PowerJam kept the fan running for my dad's CPAP and gave us something to listen to at night besides ourselves worrying. That's not a gear review. That's what it actually did for my family."

🏠
Sarah M.
Homeowner
★★★★★

"I run a food truck. PowerJam replaced my generator for everything except the fryer. No more exhaust smell at the service window. No more engine noise while I'm talking to customers. It just works — all day, every event."
