Description

Overview

Not every network has a PoE switch. The Ubiquiti POE-48-24W-G is a Gigabit PoE adapter that powers one 48V Ubiquiti device over its Ethernet cable — a UniFi access point or airMAX radio with no mains socket nearby.

One fact matters more than any other here, so it goes first: this is a passive 48V PoE injector. It is always on, and it does not negotiate like an 802.3af/at PoE switch — the moment you plug it in, 48 volts are on the cable. That is what Ubiquiti’s 48V passive devices expect, and what a 24V-only device must never receive, so check your device’s specification before you order.

This listing is the black POE-48-24W-G: 48V DC at 0.5A, 24W maximum, a Gigabit LAN port, two shielded RJ45 sockets, and an earthed AC cable in the box. The “-G” separates it from the non-G twin — full Gigabit data, no bottleneck on a fast link.

Key Benefits

First, you do not need a PoE switch to power one device. A single access point or radio can run from this one adapter, fed by a normal router or switch. That keeps small installations cheap and the wiring simple: one cable instead of a power cable and a data cable side by side.

Second, speed. The LAN port is Gigabit, so a 10/100/1000 Mbps link passes untouched. Cheaper injectors often cap data at 100 Mbps — a problem on a modern access point. The -G model keeps the full rate.

Third, protection: surge protection covers data and power lines, with ESD protection when grounded with TOUGHCable and connectors. Finally, it is small and silent — 92 × 60 × 33 mm, no fan, no setup.

Features and Advantages

Passive PoE is the defining feature. A negotiated 802.3af/at port talks to the device first and only sends power once asked; this adapter does not do that. It puts 48V on pins 4 and 5 (+) and pins 7 and 8 (−), all the time — 2-pair powering. That standard Ubiquiti arrangement works with UniFi access points, airMAX radios, airFiber and EdgeMAX devices that accept 48V passive PoE. Always check your device’s specification first — the adapter cannot protect a device never meant to receive 48V.

Both RJ45 sockets are shielded: LAN for data in, POE for power plus data out. It takes 100–240V AC at 50/60 Hz — Pakistani mains, no step-down transformer — and outputs 48V DC at up to 0.5A, at 80% efficiency.

Surge protection covers difference and common mode, clamping at 11V on the data side and 60V on the power side, with a maximum surge discharge of 1500A (8/20 µs) and a response time under 1 nanosecond. The AC connector is an IEC-320 C6 earthed type — use the included earthed cable, because the protection is designed around a grounded installation.

Ideal Users

WISPs and installers are the obvious buyers. Putting up an airMAX radio or UniFi access point at a site with no PoE switch? This is the part you reach for — one per device, one cable run. Installers also keep spares — a failed injector is a common reason a remote radio goes dark.

Home and small-office users are the second group — a single UniFi access point, or a home airMAX link between two buildings, can run from this adapter without a PoE switch.

The third group is anyone replacing a lost or failed injector. If your device already ran on a 48V Ubiquiti injector, this is the direct replacement — just confirm the model number on the old unit first; the 24V version looks physically identical.

FAQs

Is this a standard 802.3af/at PoE injector?
No. The POE-48-24W-G is a passive 48V injector — power is always on the cable, with no negotiation like an 802.3af/at port. It is made for Ubiquiti devices that accept 48V passive PoE.

Can I use it with a 24V Ubiquiti device?
No — this is the mistake to avoid. A 24V-only device will be damaged by 48V. The 24V model (POE-24-24W-G) looks physically identical, so check the model number before ordering.

Can it power a TP-Link access point?
No. TP-Link’s EAP access points — the TP-Link EAP225-Wall, TP-Link EAP235-Wall and TP-Link EAP655-Wall, for example — use standard 802.3af/at PoE, not passive 48V. The same applies outdoors, such as the TP-Link EAP225-Outdoor. This adapter is for Ubiquiti 48V passive devices only.

What is the difference between the POE-48-24W-G and the POE-48-24W (non-G)?
The power output is the same — 48V at 0.5A, 24W. The difference is the data port: the -G is Gigabit, the non-G is 10/100 Mbps only. For gigabit links, you want the -G.

Is the white version the same product?
The white variant, POE-48-24W-G-WH, has the same specifications — only the colour differs. This listing is the black POE-48-24W-G.

Does it power more than one device?
No — one adapter powers one device. Three access points need three adapters, or a PoE switch with 48V passive ports.

Why Buy From NexGenShop.pk?

The reason to buy this adapter here is the same reason to be careful buying it anywhere: the lookalikes. Ubiquiti’s PoE bricks all look alike — 24V and 48V, Gigabit and non-Gigabit, black and white are near-identical boxes with two RJ45 sockets. This listing states the exact model (POE-48-24W-G), voltage (48V), output (24W) and colour (black), so you know what is being dispatched.

The price is Rs 6,200, earthed AC cable included. Unsure whether your device takes 48V passive PoE? Message NexGenShop.pk on Facebook or Instagram with your device model before ordering. A two-minute check is worth far more than a damaged access point.

Final Conclusion

The Ubiquiti POE-48-24W-G does one job properly: it powers a single 48V Ubiquiti device over its Ethernet cable, at full Gigabit speed, with surge and ESD protection built in, for Rs 6,200 — the right part for a UniFi access point, an airMAX radio or any Ubiquiti device that accepts 48V passive PoE, where a PoE switch would be overkill.

The only condition: confirm your device accepts 48V passive PoE first. Get that right, and this small black adapter will sit quietly behind a desk or in a cabinet and do its job for years. Order from NexGenShop.pk today.
