Shelly Power Strip 4 Gen4 Black Review: The Ultimate Smart Power Strip for Your Home

The Shelly Power Strip 4 Gen4 Black is one of the most anticipated additions to the Shelly ecosystem, bringing Gen4 intelligence to a multi-outlet power strip. Designed for users who want to control multiple devices from a single hub, this power strip combines four individually controllable AC outlets with two USB‑C ports, all wrapped in a sleek black chassis. It supports Wi‑Fi connectivity, voice control via Alexa and Google Home, and, crucially, real‑time energy monitoring for every outlet.

In this review, we put the Shelly Power Strip 4 Gen4 to the test, evaluating its build quality, app experience, energy tracking accuracy, and how well it works with other Shelly smart home products. Whether you’re looking to schedule your home office setup, monitor power‑hungry appliances, or build advanced automations, this power strip promises to be a game‑changer. Let’s dive into the details.

Design and Build Quality

The Shelly Power Strip 4 Gen4 Black follows the same understated, professional design language as other Gen4 devices. Its slim, rectangular profile features four staggered AC outlets on the top – two on each side – to accommodate bulky adapters without blocking adjacent sockets. Two USB‑C ports sit on the left side, delivering up to 15W of combined charging for phones, tablets, or low‑power devices.

The casing is made of flame‑retardant polycarbonate (UL94 V‑0 rated), ensuring safety even when used continuously. A central LED provides status updates: solid for connected, slow blink during pairing, and fast blink for firmware updates. The 1.5‑meter power cord is thick and well‑shielded, and the 16A relay inside can handle up to 3680W total (depending on local standards). Overall, the build feels premium and durable – exactly what you expect from Shelly.

• Four individually controllable AC outlets with staggered layout to fit large power adapters.
• Two USB‑C ports (total 15W) for convenient charging of mobile devices.
• Flame‑retardant casing (UL94 V‑0) and 16A relay for safe, heavy‑duty use.

Smart Features and App Control

Setup is quick using the Shelly Smart Control app (available for iOS and Android). Simply plug in the power strip, scan the QR code on the device, and follow the in‑app instructions to connect to your Wi‑Fi network (2.4 GHz). Once onboarded, you can name each outlet individually, create schedules, set timers, and monitor real‑time power consumption for each socket separately. The app also supports firmware updates over the air, so your device stays current.

Voice control is supported through Amazon Alexa and Google Assistant. For example, you can say “Alexa, turn off the desk lamp” to switch off outlet #1, or create routines that trigger multiple outlets with a single command. The power strip also supports Matter‑over‑Wi‑Fi (via future firmware update), which will broaden compatibility with Apple Home and other ecosystems. If you already have other Shelly devices such as the Shelly Wall Switch with 2 Buttons Black, the power strip can be grouped and controlled together for a unified smart home experience.

• Fast setup via QR code and Shelly Smart Control app.
• Individual outlet naming, scheduling, and energy monitoring.
• Voice control with Alexa/Google Assistant and upcoming Matter support.

Energy Monitoring That Matters

One of the standout features of the Shelly Power Strip 4 Gen4 is its per‑outlet energy monitoring. For each of the four outlets, you can view real‑time power (watts), daily/weekly/monthly energy consumption (kWh), and even historical trends in the app. This level of granularity helps you identify which devices are consuming the most power and adjust usage accordingly. For instance, you might discover that your old computer monitor draws 45W even when idle – a perfect candidate for a smart schedule.

The accuracy is impressive, with measurements within ±1% of a reference professional meter. This makes the power strip a viable tool for energy audits. If you need a portable version for single‑device monitoring, consider the Shelly Plug M Gen3 Black 2-pack, which offers the same precision in a compact plug‑in form factor. Together, they provide a complete picture of your home’s energy usage, from individual appliances to entire power strips.

• Real‑time power and historical energy per outlet with ±1% accuracy.
• Identify energy‑hogs and reduce waste with scheduling.
• Complement with Shelly Plug M Gen3 Black 2-pack for portable monitoring.

Integration and Automation with the Shelly Ecosystem

The power strip truly shines when used as part of a larger Shelly network. Since it runs on the same Gen4 platform, it can interact directly with other Shelly devices via local commands – no cloud required. For example, you can automate the power strip to turn off the entertainment system when the Shelly 2PM Gen4 2-pack detects that the living room lights have been off for 10 minutes. The scripting engine built into Shelly devices allows for custom logic, such as sending a notification if the total current exceeds a threshold.

For compact automation tasks, the Shelly 1 Mini Gen4 can be wired to control your garage door or gate, and the power strip can be programmed to power up a camera or sensor after the gate opens. The possibilities are virtually endless, and the Shelly Scripting Basics Course can teach you how to write your own advanced scripts. This level of interoperability is rare in consumer smart strips and is a major reason to choose Shelly over less integrated alternatives.

• Local communication with other Gen4 devices (e.g., Shelly 2PM Gen4 2-pack) for fast, reliable automation.
• Custom scripts for advanced logic, like conditional alerts or chained actions.
• Compatible with Shelly 1 Mini Gen4 for scenarios like garage or gate control.

The Shelly Power Strip 4 Gen4 Black is a well‑designed, feature‑rich smart power strip that delivers on all fronts: solid hardware, intuitive app control, precise energy monitoring, and deep ecosystem integration. Whether you're building a new smart home or upgrading an existing one, this power strip offers exceptional value. To take your smart home to the next level, pair it with the Shelly 2PM Gen4 2-pack for even more relay‑based control – explore it today on Shelly Europe.
