| 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. | There's no built-in battery — the PC35 PRO is designed to run off a portable power station or inverter (BougeRV specs a 2kW continuous output source to absorb the startup surge, though the inverter compressor then settles to roughly 320-500W). On a common 1,000Wh power station that translates to about 2-3 hours of steady cooling; pair it with a 2kWh+ station for a full night. Twin ducts route out a tent port or window gap, with replacement ducts and adapters sold separately. Condensate drains via a simple port — in a tent, just let it run outside. At 22 lbs with an IPX5 rating, it genuinely goes anywhere. |
