The Cool Surge Portable Air Conditioner “is a work of genius…so advanced that no windows, vents or freon are required.” With advertising copy like that, there’s no wonder folks are lining up to spend $298 to get one. (Cool Surge is a division of Heat Surge, the same folks that sell the Amish fireplaces.)
Once you’ve frozen the two “glacier packs” (no different from the keep-your-lunchbox-cool gel packs) and filled the unit with about a gallon of water, the Cool Surge claims to blast out “ice-chilled” air for hours, using only the power of a 60W light bulb.
Consumer Reports took the Cool Surge to task and found that during a four-hour test the device “failed to appreciably cool” a 227-square-foot room that began at 85° F and 57% humidity, common conditions for an average summer day. At “desertlike” 25% humidity, after four hours, the Cool Surge dropped the room by only two degrees. Based on these results, Consumer Reports has given the Cool Surge the “Don’t Buy: Performance Problem” rating.
