Cybertake S2 Pro Portable Air Conditioner vs EcoFlow Wave 3 Portable Air Conditioner

The EcoFlow Wave 3 is the stronger cooler and heater, with 6,100 BTU of cooling and 6,800 BTU of heating, and its dedicated 1024Wh LiFePO4 battery makes true cordless use simple. The Cybertake S2 Pro is lighter at 25.6 lbs, runs from 12V, 24V, 48V or wall power, and its IPX4 housing and shockproof build suit rough travel. Pick the Wave 3 for more output and a cleaner battery setup; pick the S2 Pro for lighter weight, more input options and a tougher shell.

  • Choose the Cybertake S2 Pro if you want the lightest unit, multi-voltage DC input and a rugged waterproof body for trucks, tents and rough roads.
  • Choose the EcoFlow Wave 3 if you want more cooling and heating output and a detachable 1024Wh battery for genuinely cordless runtime.

What reviewers say

Questions and answers

Which cools a small room faster?
The EcoFlow Wave 3. Its 6,100 BTU cooling beats the S2 Pro's 3,300 BTU DOE rating and its claimed 5,100 BTU peak.
Which is better for truck sleeping or a camper?
The Cybertake S2 Pro. It runs directly from 12V or 24V DC with a booster, weighs less and has a rugged IPX4 shell.
Which is better for off-grid camping without a power station?
The Wave 3 bundle, because its 1024Wh LiFePO4 battery gives cordless runtime. The S2 Pro needs a separate DC source.
Which lasts longer?
Both carry a 1-year parts warranty on the S2 Pro side; EcoFlow's battery uses long-life LiFePO4 chemistry. Real-world life depends on use and care.
Is the Wave 3 worth stepping up to?
Yes if you need more cooling and heating output and a matched battery. The S2 Pro makes more sense if weight and multi-voltage input matter more.
