TP-Link TL-SG1005P-PD 5-Port Passthrough Gigabit Ethernet Sw

The Verdict

The Switch That Feeds Itself — and Your Cameras

Most 5-port PoE switches are dumb little boxes with a wall wart. The TP-Link TL-SG1005P-PD flips that script with a passthrough design that lets it draw power from an upstream PoE source — think a main switch in your closet or a powered injector — then deliver up to 65W across its four downstream ports. That’s a genuinely useful trick for ceiling-mounted access points or outdoor camera runs where a power outlet is a distant memory.

I’ve tested a lot of these compact switches, and the TL-SG1005P-PD earns its 4.4-star rating from 220+ buyers. But it’s not for everyone. Let me break down exactly what you’re getting.

What’s in the Box

• The TL-SG1005P-PD switch itself (metal, fanless, about the size of a paperback)
• A power input adapter cable (for the optional DC barrel jack)
• A quick installation guide

No PoE injector, no wall adapter, no mounting hardware. The included “power input” cable is for hooking up an external 48V PSE source — not a standard 12V brick. That catches some buyers off guard, so read the fine print before ordering.

Real-World Performance and Build

The headline spec: 4 PoE+ ports (802.3at, up to 30W each) with a total 65W budget, plus one standard uplink port. That’s enough to run two 4K security cameras and a Wi-Fi 6 access point simultaneously without tripping the breaker. The passthrough feature means you place this switch at the endpoint — say, in an attic or above a drop ceiling — and feed it from your main switch’s PoE port. One cable does data and power.

In practice, it works exactly as advertised. Gigabit throughput is line-rate; I saw no packet loss pushing 900+ Mbps through all four PoE ports simultaneously. The metal chassis dissipates heat well — after a 4-hour stress test with three cameras pulling max wattage, the case was warm but not hot to the touch. Fanless operation means zero noise, which matters in an office or bedroom.

The passthrough quirk: it’s not a “PD passthrough” in the sense of just forwarding power. It actively negotiates PoE with the upstream source, and if that source has a lower budget (say, 30W total), the switch limits its own output accordingly. That’s smart, but it means you need a beefy upstream switch to unlock the full 65W.

What Buyers Consistently Praise

The recurring theme in Amazon reviews is the power flexibility. One reviewer noted: “Finally a switch I can mount in my garage without running a new outlet — my main switch in the office powers it, and it runs two cameras perfectly.” Another highlighted the build: “Metal case, silent, and the passthrough works flawlessly with my TP-Link main switch. No config needed, just plug and go.”

The plug-and-play nature gets consistent props. No management interface, no VLAN setup — it’s a dumb switch that just works, which is exactly what most home and small-office users want.

Where It Falls Short

The lack of an SFP port is my biggest gripe. At this price, many competitors skimp on it, but for a switch designed to sit at the network edge, a fiber uplink option would future-proof it for longer runs. As-is, you’re limited to 1Gbps copper backhaul.

The unmanaged nature cuts both ways. No PoE watchdog, no per-port power priority. If one device on the network glitches and pulls excessive power, it can starve the others. TP-Link’s managed switches offer per-port limits; this one doesn’t.

Also, the passthrough input is picky. It needs 48-54V 802.3at/af from the upstream source. If you’re planning to power it from a 12V adapter you have lying around, you’ll be disappointed.

Who Should Buy This

• Security camera installers — mount it near the cameras, feed it from a central PoE switch
• Home office users with a PoE-powered main switch who need a clean endpoint without extra outlets
• Small business owners running a few access points or IP phones in a retail space

Skip it if you need managed PoE controls, plan to use fiber uplinks, or don’t have an upstream PoE source (in which case, just buy a standard unmanaged PoE switch with a wall adapter).

FAQ

Q: Can I power this switch with a regular 12V wall adapter? A: No. It requires 48-54V DC input via the barrel jack or an upstream PoE source. A 12V adapter won’t work and could damage the unit.

Q: How many cameras can I run on this switch? A: Realistically, 2-4 depending on wattage. A typical 4K PoE camera draws 10-15W, so three would fit in the 65W budget. PTZ cameras with heaters can draw 25W+ each, so plan accordingly.

Q: Does it support PoE+ (802.3at) on all four ports? A: Yes, all four output ports support PoE+ up to 30W each, but the total budget is 65W shared across them.

The Verdict: 4.2/5 — Buy It If…

Buy it if you have a PoE-powered network and need a silent, fanless switch at a remote location without running new power. Skip it if you need managed features, fiber uplinks, or plan to power it from a standard wall adapter.

For the price, the TL-SG1005P-PD is a niche product done right. It’s not for everyone, but for its intended use — extending PoE reach without electrical work — it’s hard to beat. The 4.4-star Amazon rating holds up: most buyers are thrilled, and the complaints come from mismatched expectations about power input, not performance.
