Your needs, this model
Does it fit your priorities?
Can each AC outlet be controlled separately while all four USB ports are on?
Meross describes the four AC sockets as individually controlled and the four USB ports as group-controlled. The USB group has a maximum output of 4.0 A, so it is not four independent 4 A charging outputs. The product image shows one strip, not a plug bundle.
Explore this need in the finder →Does the 15 A rating apply to each socket?
No. The US page gives 15 A for the power strip as a whole and does not list a separate per-socket ceiling. Add the simultaneous AC loads conservatively and follow the strip label; neither the four outlets nor the 1.8 m cord create additional capacity. Meross does not publish a motor rating here.
Explore this need in the finder →Can I put this strip on an outdoor patio?
No. The exact MSS425FHK US manual recommends indoor use in a dry location only. Its four outlets and HomeKit branding do not establish moisture protection or outdoor suitability.
Explore this need in the finder →Assessment basis: This document-based assessment covers the official Meross MSS425FHK US power strip, listed as SKU MSS425FHK-US. I have not installed it, tested individual outlet control, measured USB charging, or verified any surge behavior. The pictured package is one power strip with a 1.8 m attached cord—not a bundle of four plugs.
Four switched AC outlets share one strip rating
Meross describes four AC outlets that can be controlled individually, alongside four USB ports controlled together as a group. The distinction affects daily use: the USB bank is not four separately scheduled smart outlets. The official material gives a maximum 4.0 A output for the four-port USB group. It also lists a maximum of 15 A for the AC strip as a whole. That is not 15 A per AC socket. The checked US pages do not give a separate per-outlet current limit, an overall watt ceiling, or a motor horsepower rating; do not infer one from the socket count or from another Meross strip. For simultaneous loads, compare every appliance nameplate with the strip label and the manual's instructions. The US family table lists the body at 12.2 × 2.4 × 1.4 inches, excluding its cord, and the store listing states a 1.8 m cable. Think about more than the strip body: its position, cable route, plug orientation and access to each control all matter. The exact MSS425FHK manual says indoor use in a dry location. The model does not become outdoor-safe because it sits under a desk, nor does the number of outlets establish surge suppression. The sources checked do not provide a joule rating; if surge protection is the primary need, verify an exact protective specification from the seller and manual before choosing it.Smart-home routes and routines are not the same in every app
The official material lists Apple Home, Alexa, Google Home/Assistant and SmartThings for this US HomeKit strip. Its network specifications reference 2.4 GHz Wi-Fi; the US store says it can work with 2.4 GHz or dual-band routers. For Apple Home remote access, Meross says a compatible HomePod, Apple TV or iPad must act as an always-online home hub. Confirm your selected ecosystem, Wi-Fi setup and remote-control needs rather than assuming the strip itself supplies a home hub. Meross documents app schedules and a countdown or auto-off function for the strip/family, while its general app FAQ distinguishes schedule settings from auto-off timers. This supports a Meross-app routine route for the assessment. It does not certify that Apple Home, Alexa, Google Home or SmartThings exposes the same routine options. Nor does it prove that users can control the strip from the app if their internet service fails. The checked US sources do not identify MSS425FHK as Matter, and they do not document energy monitoring or Away Mode. I have left those capabilities unknown instead of borrowing specifications from a similarly named family member.Fit the layout and load, not just the number of outlets
The MSS425FHK is worth considering when a dry indoor workspace needs several independently switched AC loads plus a shared USB bank and the listed smart-home app route. Its four AC points may be more useful than a single plug, but they do not provide four independent 15 A capacities. The USB bank's 4 A ceiling is likewise shared, so add the requirements of devices that may charge at the same time. If separated locations, measured energy use or an explicit motor rating matter more, compare specific plug models that publish those facts rather than counting ports. Before purchase, confirm the offer is the US MSS425FHK rather than a different regional strip, check the attached cord will reach without tension, and plan the position so controls stay accessible. Verify whether the USB group behavior matches your routine, and inspect the product label/manual for the requirements of the actual appliances. The family page's specifications do not establish individual AC socket limits or surge joules. The manual's dry-indoor restriction remains in force even when the strip is used with voice control. This review describes manufacturer material only; it makes no claim of personal testing, product ownership, measured charging speed, outlet reliability or safety certification.Key specifications
