Why this product
The TP-Link Kasa HS103P4 is the smart plug bundle most new smart home buyers should start with in 2026. At $25 for four plugs, it lands at roughly $6 per outlet, well below the per-plug cost of any other bundle with a comparable owner-rating track record. The Kasa app handles schedules, away mode, scenes, and ties into Alexa, Google Assistant, and SmartThings without a separate hub.
The HS103P4 has been on sale long enough to accumulate hundreds of thousands of Amazon ratings averaging 4.7 stars. That kind of volume signals a product that holds up across very different home setups. The recurring critiques (2.4 GHz only, no energy monitoring) are honest limits of the SKU rather than reliability problems.
What TP-Link claims
TP-Link rates each Kasa HS103P4 plug at 15A for resistive loads, with a compact body designed to leave the second outlet on a standard duplex free. The plug speaks 2.4 GHz Wi-Fi (802.11 b/g/n) and pairs through the Kasa Smart app on iOS and Android. Schedules, away mode, countdown timers, and scenes are handled in the app without a cloud subscription.
Voice control covers Alexa, Google Assistant, and Samsung SmartThings. Apple HomeKit is not supported on the HS103P4 (TP-Link sells separate HomeKit-certified SKUs). There is no energy monitoring on this model. For per-outlet energy data, the step-up is the Kasa HS300 power strip with six metered outlets.
Who should buy the Kasa HS103P4
Buy the HS103P4 if you want app and voice control on lamps, fans, holiday lights, or any plug-in appliance, you are already on Alexa or Google Assistant, and you want the cheapest credible bundle. Skip it if you need HomeKit, per-outlet energy data, or you are on a Wi-Fi network that aggressively forces 5 GHz on new devices.

Frequently asked questions
Is the Kasa HS103P4 4-pack worth $25 in 2026?+
For most households, yes. At roughly $6 per plug, the HS103P4 is the cheapest bundle with a credible owner-rating track record and broad voice assistant support. The recurring complaint in long-tail reviews is 2.4 GHz Wi-Fi pairing on mesh networks, not failures of the plugs themselves.
Does the Kasa HS103P4 require a hub?+
No. Each plug connects directly to a 2.4 GHz Wi-Fi network and pairs through the Kasa app. There is no separate hub or bridge. The trade-off is that every plug counts against your Wi-Fi client limit.
Will the Kasa HS103P4 work with HomeKit?+
Not natively on this SKU. Kasa offers HomeKit-certified plugs as separate models. If HomeKit is a hard requirement, look at the Kasa KP125M (Matter) or stay in Alexa, Google, and SmartThings ecosystems with the HS103P4.
Why is the Kasa HS103P4 sometimes flaky on mesh Wi-Fi?+
The plug is 2.4 GHz only. Some mesh routers use band steering that pushes new devices to 5 GHz during onboarding, which the plug cannot join. The fix in most owner reports is to temporarily disable 5 GHz during setup, then re-enable it once each plug is paired.
