MERCUSYS MS108GP, eight-socket gigabit switch with seven powered sockets review
A gigabit switch that powers seven of its eight sockets and states both halves of the power question — 30 W at one socket, 65 W for all — in an Amazon.com description that is the whole page.
Amazon.com listed it on October 26, 2026, but no current offer passed our price check, so no price is quoted. The Amazon.com page exists, but nobody was selling the unit; a listing in that state is often a third-party import.
Models on this shelf that Amazon.com did sell on that date:
The title: TP-LINK MS108GP 8-port gigabit desktop switch with 7-port PoE+. There are no bullets. The description: 8 × 10/100/1000 Mbps RJ45 ports; seven PoE+ ports; up to 30 W per PoE port and 65 W for all; Extend mode to 250 m; a one-click isolation mode; compatibility with IEEE 802.3af/at devices; a metal casing for heat dissipation; plug and play; and a five-year warranty.

Every switch here is gigabit and names IEEE 802.3af/at, except the NETGEAR, which says PoE+ without the standard’s number.
65 W, shared
The per-socket ceiling is what one device can draw; the total is what all of them share. Two access points at 25 W leave 15 W for the other five sockets.
Availability
Amazon.com listed the MS108GP on October 26, 2026, but no current offer passed our price check, so no price is quoted.

The questions that come up before an order
How many devices can it power?
As many as fit in 65 W: seven 802.3af devices at their 15.4 W maximum would ask 108 W, so a mix of low-power cameras and phones is what fits. Two 30 W devices take almost all of it.
Why does the title say TP-LINK?
Mercusys is a TP-Link brand; the listing's brand field is Mercusys and its title says TP-LINK.
Our score
7.6/ 10
A small PoE+ switch with its power figures, its Extend mode and a five-year warranty stated, on a one-paragraph Amazon.com page. 65 W shared is the figure to plan around.
The buyer this one serves, among network and storage gear
A small camera or access-point setup — a few low-power devices — behind a router, where a five-year warranty matters.
What this one costs among network and storage gear

802.3af and 802.3at · 250 W total, no per-socket figure · sixteen powered of eighteen · two gigabit uplinks · one-key VLAN mode · unmanaged
An eighteen-socket switch with sixteen powered sockets and a 250 W shared budget, which never states what one socket can deliver and contradicts itself about how it mounts.
Best for: A building with a dozen or more cameras where the total draw is known and the switch will live in a cupboard, and where the per-socket question can be settled with the seller first.
802.3af and 802.3at · up to 30 W per socket · 250 W total · sixteen powered of eighteen · uplinks numbered 17 and 18 · internal supply · fan-cooled
A rack-mounted eighteen-socket switch with sixteen powered sockets, an internal power supply and fans, which numbers its uplinks and isolates the powered sockets from each other.
Best for: A rack in a cupboard or a small server room carrying a camera installation, where fans are inaudible and an internal supply saves space.
PoE+ named, no IEEE class printed · 62 W total · eight powered sockets · managed, with VLANs and QoS · per-port PoE control · fanless metal case · desk or wall
The only managed switch on this shelf: eight PoE+ sockets with per-port power control, VLANs and QoS, a 62 W budget and a fanless metal case — $59.99 on Amazon.com on October 26, 2026.
Best for: A small office or a home lab that wants VLANs and per-port power control for a few cameras, phones or access points.
