Shelly Plug US Gen4 White (US, 4-pack) review: fit and tradeoffs

Your needs, this model

Does it fit your priorities?

Are the four units one larger-capacity outlet?

No. The exact White / 4-pack variant record identifies EAN 3800238074319 and four individual plugs. Each device retains its own 15 A / 1,800 W resistive maximum; the package is not a single 60 A or 7,200 W outlet.

What body size should I allow for each plug?

Shelly's product page lists 1.50 × 2.52 × 2.01 in (H × W × D); its printed guide gives slightly smaller figures. The finder conservatively uses the larger per-axis values, but body dimensions do not prove wall-plate or neighboring-outlet clearance.

Can I schedule all four devices?

The device guide lists up to 20 schedules per plug. Treat the four included units as four individually configured points; the checked sources do not establish that one action automatically provisions identical schedules on every device.

Assessment basis: this review is for the Shelly USA white four-unit package of Plug US Gen4, model S4PL-00116US; the exact storefront variant record gives EAN 3800238074319. It is a document-based fit assessment, not a hands-on test. I have not installed or operated any of the four plugs, and this package identifier is not an Amazon ASIN.

Four separate control points change the buying question

The white 4-pack contains four one-outlet plug units, not a four-outlet strip. Each device sits in its own receptacle, has its own pairing and room placement, and keeps the same per-device ratings as the single package. The count may suit repeated lamps or other resistive loads in different locations, but there is no package-wide 60 A / 7,200 W allowance. It is more hardware to inventory, configure and reassess if the home network, app choice or outlet layout changes. A four-unit box is sensible only when four independently controlled outlets are likely to be used. The exact white variant is associated with base model S4PL-00116US and EAN 3800238074319. Shelly's official materials describe a single NEMA Type-B outlet on each body, power/energy metering, Matter compatibility, a Wi-Fi route and a Zigbee alternative. The default firmware is Matter; the printed guide says five rapid button presses change firmware to Zigbee. These are not concurrent modes. The Matter route needs a compatible Matter controller for third-party setup; Zigbee needs a compatible coordinator. Decide which control plan fits the home before multiplying that setup across four locations. The product-specific integration list names several smart-home services, but it does not mean every service exposes every feature or works without its own requirements.

What the rating does and does not say

Shelly publishes 120 V, 15 A maximum switching current and 1,800 W maximum output for resistive load only. This is a per-plug limit. Do not treat four packages as a single larger outlet, or assume the resistive maximum applies to a motor, compressor, transformer or other load with different electrical behavior. The checked US materials provide no horsepower limit. Even four compatible appliances still need to be evaluated individually against their own nameplates and instructions, and the branch circuit has a separate capacity question that this product review cannot approve. Power and energy metering are advertised, and the printed guide shows current, voltage and power/energy meter fields. That makes the Shelly app a relevant route for viewing device readings. However, the sources do not state an independent accuracy tolerance, so those readings are not described here as laboratory-verified, revenue-grade or a guaranteed bill reduction. The manufacturer also lists up to 20 schedules per device. It does not establish that one setup action synchronizes a repeated schedule across all four units. Treat them as separate smart devices unless the chosen app documents a group workflow for the exact firmware and controller arrangement.

Physical fit is per device

Shelly's product page specifies 1.50 × 2.52 × 2.01 inches (H × W × D); its printed guide lists 1.42 × 2.52 × 1.99 inches. The sources agree only on width, so numeric finder matching uses the shared 2.52-inch width and withholds height and depth. Measure the body against every wallplate and neighboring plug, then allow for the appliance cord and any adapter. A four-pack photograph verifies four matching bodies; it does not prove that four crowded sockets will be usable in a particular room. The sources do not establish outdoor or damp-location approval, so this profile treats the plug as indoor-only.

Routines, local use and setup caveats

The Shelly guide describes an embedded web interface on the local network, and the product page discusses local automation plus a one-hour countdown shutoff. Once configured, a local network path can differ from cloud-based remote control. It still depends on a working home LAN and power; it is not offline first-time commissioning or remote-from-away use during an internet outage. The product-specific timer evidence is for the Shelly/device route; identical Apple Home timer controls are not established, and Away Mode is undocumented. The Apple Home path also does not have a confirmed energy-history display in the checked product-specific materials, so use Shelly Smart Control for the documented metering view.

Who should choose four?

Shortlist this package when four separate indoor locations need compatible resistive-load switching, and the household is prepared to pair, name and check four units individually. If only one or two locations matter, compare the single or two-pack configuration rather than assuming a larger box is automatically better value. This is not a dimmer, outdoor plug or documented motor-control solution. Check exact package identity, each appliance rating, compatible controller or coordinator, the physical outlet layout, and seller return terms before ordering. The exact-name CPSC query checked on 2026-10-31 returned an empty result list; that limited search is not a safety certification or a promise about later recall status. No ownership, customer experience, test measurement or energy saving is claimed.

Key specifications

Key details at a glance

Controlled outlets	Single plug multi unit package
Reviewed package	Four white plugs; exact storefront variant is White / 4-pack.
Maximum current	15 A
Maximum published watts at 120 V	1800 W
Motor limit	The checked US materials do not publish a horsepower limit. The 15 A / 1,800 W maximum output is explicitly for resistive loads only and applies to each plug separately.
Body width	2.52 in
Network and protocol	The default firmware is the Wi-Fi/Matter route. Five rapid button presses switch the device to Zigbee firmware; Matter and Zigbee are alternative firmware modes, not simultaneous control modes. The checked materials describe 2.4 GHz Wi-Fi, Bluetooth LE and a built-in local web interface.
Indoor use only	Yes
Outdoor rating	No
Schedules documented	Yes
Countdown timer / auto-off	Yes
Matter controller for third-party app	Yes
