Dual vs Single Socket Outdoor Plugs
Socket Count
The Kasa Outdoor Dual-Socket Smart Plug (EP40) provides two independent AC outlets in a single unit. You can control each socket separately through the Kasa app. This allows you to manage different devices, like a pool pump and landscape lighting, without needing extra hardware. The Kasa Single-Outlet Outdoor Smart Plug (KP401) offers only one socket. You need two KP401 units to achieve the same dual-outlet capability. The EP40 consolidates power points, reducing the number of plugs occupying your outdoor electrical panel or extension setup.
Physical Dimensions
Size matters when fitting these plugs into tight outdoor spaces or standard outlet boxes. The EP40 measures 4.9 inches in length, 2.38 inches in width, and 2.29 inches in height. The KP401 is more compact, measuring 3.13 inches in length, 1.53 inches in width, and 2.76 inches in height. The single-outlet model is significantly narrower and shorter. If you are installing these near other outlets or in a crowded junction box, the smaller footprint of the KP401 may offer better clearance for adjacent devices.
Variations
Both models appear in multiple variations, though the options differ. The EP40 comes in 2-Socket, Apple HomeKit 2-Socket, and Matter 2-Socket versions. This gives you specific protocol choices for your ecosystem. The KP401 is available in 1-Socket New Version and Dimmer 1-Socket options. The dimmer variation suggests a different internal mechanism or control type not present in the standard outlet version. If you need Matter support or Apple HomeKit integration with two sockets, the EP40 variations provide that path. The KP401 dimmer option is unique to the single-outlet line.
Wi-Fi Range
Both the EP40 and KP401 feature a built-in power amplifier for long-range Wi-Fi. The published specification states a reach of up to 300 feet in open space for both models. They both require a 2.4GHz Wi-Fi connection for setup and operation. Since the range capability is identical, you do not gain an advantage in signal strength or distance by choosing one over the other. Your router placement and wall thickness will determine the actual performance for both devices equally.
Power Capacity
Each outlet on the EP40 supports up to 15A/1875W. The KP401 also supports up to 15A/1875W per socket. The maximum load rating is identical for every individual socket across both product lines. You can run high-wattage appliances like pool pumps or holiday light strings on either device without exceeding the electrical limits. The power handling capability does not distinguish one model from the other in terms of raw capacity.
Which Kasa Outdoor Plug Fits Your Needs
Users needing separate control for two devices
The EP40 model gives you two independent AC outlets. You can manage each socket separately via the app. This setup is ideal if you need to control distinct items like landscape lighting and pool equipment without sharing a single circuit. The dual-socket design keeps your outdoor setup organized while maintaining individual control over each connected device.
Users wanting a compact single outlet solution
The KP401 model features a smaller footprint with dimensions of 1.53 by 3.13 inches. It offers a single 15A/1875W outlet for standard outdoor use. This compact size fits well in tight spaces where the dual-socket unit might be too large. You still get the same 300-foot Wi-Fi range and IP64 weather resistance for reliable outdoor performance.
Users prioritizing individual socket management
If you need to toggle devices independently, the EP40 is the better choice. Its dual-socket design allows you to turn one outlet on while leaving the other off. This flexibility is useful for managing different schedules or usage patterns for separate appliances. You retain full app control over each socket individually, providing greater versatility for your outdoor electronics.
