Power System

Built for the Decade.
Not the Product Cycle.

⚡
LiFePO4 — 2,000+ Cycles
Lithium-ion NMC starts declining after ~500 cycles — 17 months of daily use. LiFePO4 reaches 2,000+ before meaningful degradation. Thermally stable to 518°F. We chose this chemistry because we build for the decade, not the product cycle.
🔌
Pure Sine Wave AC
Modified sine wave causes problems with sensitive electronics, CPAPs, and motor-driven tools. Pure sine wave is what your wall delivers at home. PowerJam delivers the same. Not a compromise.
💻
USB-C PD 60W+
Fast-charges laptops, tablets, and phones simultaneously without a separate brick. The port that keeps a MacBook Pro alive through a full day in the field.
☀️
Solar + Pass-Through
100W–400W panel compatible. Solar charges while you draw power from any port. True off-grid system — not just a battery you plug in at home.
⚡
Audio System

Engineered for Outside.
Not a Living Room.

🔊
📊
RMS — Not Peak
Peak watts is the number every budget brand advertises because it's always larger. RMS is the sustained output delivered all day without distortion. We advertise RMS. That's it.
🎵
Full-Range Driver Array
Woofer + tweeters covering the complete audible spectrum. Not the compressed mid-heavy sound of a single driver working beyond its design range.
🔉
Passive Radiator Bass
Low-frequency output without a powered subwoofer. Bass you feel at a campsite and jobsite. Not just bass that shows up in a quiet room with the volume at 30%.
📡
Bluetooth 5.0 + aptX
aptX codec for near-CD audio quality over wireless — the codec gap between Bluetooth that sounds like Bluetooth and Bluetooth that sounds like a wire.
The Build

IP65. Drop-Tested.
Built for Where You Work.

🛡
IP65 Weatherproof
Dust-tight. Rain-resistant under direct water jets. Not IPX4 — the splash-proof rating designed for a poolside photo shoot. IP65 means field-rated protection: rain, dust, sand, barn debris, jobsite grit.
💪
Drop-Tested
Reinforced corner protection. Impact-resistant housing. Port covers that don't crack. Tested at the drop heights that happen on real jobsites — not controlled lab conditions designed to produce a passing score.
🔒
Sealed Port Covers
Every port protected by a sealed cover when not in use. Dust and moisture find every unprotected gap. We closed every gap before they became a field failure.
🥶
Cold-Weather Rated
LiFePO4 holds capacity in cold measurably better than lithium-ion NMC. Full rated output in winter conditions where competing units are throttling to protect themselves.
