| Install | No window kit required — the Wave 3 uses insulated ducts you route out a tent flap, van window, or cracked door, with adapters for different openings. The optional 1,024Wh LFP add-on battery (about $520 extra at current pricing, $899 list) snaps under the unit and delivers up to 8 hours in eco mode — expect 2-4 hours of real compressor-on cooling in serious heat. It recharges in as little as 75 minutes from AC plus 400W solar combined, and also takes 12V/24V car power at up to 200W. Condensate is mostly self-evaporated with a drain hose fallback for humid climates. Unit alone is 34 lbs; add about 21 lbs with the battery. | The Mark 3 is a true dual-hose design — one duct pulls fresh air, one exhausts heat — so it doesn't depressurize your tent or van the way single-hose units do; route both ducts out a tent port or cracked window. An active condensate pump pushes water out automatically, a genuine luxury in the category. Each 1,022Wh battery (about $700, 14 lbs) snaps onto the unit: expect up to 7 hours in sleep mode but a realistic 3-5 hours of normal cooling, or 2-3 hours in max 'Rocket' mode. It charges from a wall outlet (about 5 hours, 80% in 2), a 12V car socket, or up to 500W of solar — it's the first battery AC to take that much panel input. |
