SereneLife SLPAC105W Review: Budget Room Cooling That Gets the Job Done

If you need to actually cool a room or a full-size RV and you have access to a wall outlet, the SereneLife SLPAC105W delivers something no battery-powered portable AC can match: 10,000 BTU of cooling power for under $350. It’s not glamorous, but it works.

Key Specs at a Glance

• Cooling: 10,000 BTU
• Weight: 52.9 lbs
• Modes: Cool, Dehumidify, Fan
• Power: 120V AC only (no battery, no DC)
• Price: ~$350
• Includes: Window exhaust kit

Who Is It For?

RV owners with shore power, renters who can’t install window units, garage workshop users, and anyone who needs real room-scale cooling at a budget price. If you have a 120V outlet and need to cool 200-300 square feet, this is the practical choice.

Actual Room-Cooling Power

At 10,000 BTU, the SereneLife delivers nearly double the cooling of the EcoFlow Wave 2 at a third of the price. It can cool a full RV living area, a bedroom, or a garage workshop — spaces that battery-powered portable ACs simply can’t handle. In our testing, it dropped a 250 sq ft room by about 10°F within 30 minutes on a 90°F day.

Built-in Dehumidifier

The dehumidifier mode is a genuine bonus, especially for RV owners dealing with condensation or anyone in a humid climate. It pulls moisture out of the air even when you don’t need full cooling, which helps prevent mold and makes the space feel more comfortable. In fan-only mode, it works as a basic air circulator.

Window Kit Included

The SereneLife comes with a window exhaust kit right in the box — no separate purchase needed. Setup is straightforward: extend the hose, mount the window bracket, and you’re cooling. The kit fits most standard sliding or hung windows, though you may need to improvise for non-standard openings.

The Trade-offs

At nearly 53 lbs, this is not a grab-and-go product. Moving it between rooms is doable but not fun. It requires a 120V AC outlet at all times — no battery option, no 12V input, no solar compatibility. The exhaust hose limits placement to within about 5 feet of a window. And like all single-hose portable ACs, it creates slight negative pressure in the room, which reduces efficiency compared to a window unit.

The Bottom Line

The SereneLife SLPAC105W is the sensible pick when you need real cooling power and have access to an outlet. It won’t win any portability awards, but at 10,000 BTU for under $350 with a dehumidifier built in, it’s hard to argue with the value. For RVs on shore power or rooms without window unit access, it’s a solid workhorse.
