TRENDnet Gigabit PoE++ Injector, Convert A Non-PoE Port to A PoE++ Gigabit Port (TPE-119GI)
Quick take
The TRENDnet TPE-119GI is a Gigabit PoE++ (802.3bt) injector that adds power to a non-PoE gigabit switch port. It can supply up to 15.4W (PoE), 30W (PoE+), or 95W (PoE++) depending on the connected device, using auto-sensing to deliver the correct wattage. The main caveat: it is an injector (one device per unit), so it is best when you need PoE++ for specific endpoints like cameras or access control, not as a replacement for a multi-port PoE switch.
Pros and cons
Pros
- 802.3bt PoE++ support with auto-sensing for the right wattage (up to 95W).
- Gigabit data throughput (1 x gigabit in, 1 x gigabit PoE++ out).
- Up to 100m (328 ft) PoE++ connection range.
- Wall-mount design with a sturdy metal enclosure for installation flexibility.
Cons
- Best suited for powering individual PoE devices, since each injector handles a single Ethernet-powered endpoint.
- Requires a non-PoE source port, so if you already have a full PoE++ switch, an injector may be unnecessary.
What buyers think
Buyer-review evidence points to a consistent theme of straightforward setup and stable operation when powering PoE cameras. Several reviews describe “plug and play” behavior and reduced issues after adding the injector, especially in multi-camera situations where PoE power from an upstream device was not sufficient. Reviews also commonly mention build quality (including the metal enclosure) and practical fit for rack or shelf-style installs. Overall, the review pattern suggests the TPE-119GI is valued for reliability in day-to-day powering of PoE devices and for making existing networks PoE-capable without major rewiring.
What this PoE++ injector actually does
This injector bridges data and power in a simple workflow: connect the injector’s gigabit data in to a non-PoE gigabit switch port, then run one Ethernet cable from the injector’s PoE++ out port to your powered device. The device sees a PoE++ Ethernet link, and the injector provides power over the same cable.
Power delivery is designed to scale with the endpoint. With auto-sensing, the injector supplies power in the PoE tiers it supports, up to the maximums for PoE (15.4W), PoE+ (30W), and PoE++ (95W). That means you can match higher-power devices without needing separate power bricks.
Key specs that matter for buying
Power class support up to PoE++ 95W
If your endpoints require 802.3bt-level power, the TPE-119GI is built for that use case. Its auto-sensing feature is particularly relevant if you run a mix of PoE levels across devices, because it is intended to deliver the appropriate wattage rather than forcing a single fixed output level.
Gigabit Ethernet data rates
The injector supports gigabit networking (1000 Mbps). This matters for bandwidth-hungry devices like IP cameras, VoIP phones with richer traffic, or network gear where you do not want to cap throughput below gigabit.
Up to 100m reach
For cabling runs up to 100 meters (328 ft), the injector is designed to maintain the PoE++ connection for the powered endpoint. That makes it a practical choice for typical indoor and structured cabling lengths.
Installation flexibility
The TPE-119GI uses a wall-mount design and includes a sturdy metal enclosure. Buyers also note it fits well in tight rack shelf setups, which is useful when you need a neat, centralized place for inline power conversion.
Pros and cons in real-world terms
Pros (when it fits)
- Great for upgrading an existing non-PoE switch: If you have gigabit ports available but lack PoE++ power, an injector can extend PoE++ capability without replacing the whole switch.
- Helpful for higher-power PoE devices: The injector is meant for PoE++ devices that can draw up to 95W, depending on the endpoint.
- Simple deployment: Reviews repeatedly describe quick setup, with the injector establishing the PoE link to the powered device without complicated configuration.
Cons (how to avoid disappointment)
- One injector per powered device: For many endpoints, you may spend more on individual injectors than you would with a multi-port PoE++ switch.
- Not necessary with a true PoE++ switch: If your switch already provides 802.3bt power on the ports you need, an injector adds cost and extra hardware in the path.
Who should buy it
- You want to convert a non-PoE gigabit switch port into PoE++ for one (or a small number of) endpoints.
- Your devices include higher-watt PoE++ endpoints such as certain IP cameras, access controls, or other 802.3bt-capable equipment.
- You care about tidy installs and durability, and you prefer a wall-mount metal enclosure for placement near the rack or cabling runs.
- You need auto-sensing behavior so the injector can supply the correct PoE tier to the connected device.
Who should look for a different option
- You plan to power many devices at once and want simpler management, likely making a multi-port PoE++ switch the more efficient solution.
- You already have a fully loaded PoE++ switch with enough wattage budget and port count.
- You only need very low-power PoE for a few endpoints and want to minimize upfront cost, since injectors are typically used for specific upgrades rather than general-purpose power distribution.
Verdict
The TRENDnet TPE-119GI is a practical PoE++ injector for buyers who need to turn existing gigabit ports into high-watt PoE++ power. The strongest reasons to consider it are its 802.3bt support up to 95W, auto-sensing power delivery, and a straightforward install path for powering PoE devices up to 100m away. If you are powering just a handful of endpoints from a non-PoE switch, this injector approach is often the cleanest way to get PoE++ without replacing your entire network switch.
FAQs
Does this injector support PoE++, PoE, and PoE+?
Yes. It is designed for PoE++, PoE+, and PoE devices, with supported power levels up to 95W for PoE++ endpoints. Auto-sensing is intended to deliver the correct wattage needed by the connected device.
What do I need on the switch side to use it?
You connect the injector to a non-PoE gigabit switch port. The injector then provides the PoE power to the powered device on the cable to the endpoint.
How far can it power a PoE++ device over Ethernet?
The injector is rated for PoE++ connections up to 100m (328 ft).
Will it work for IP cameras or access control devices?
It is intended for a wide range of PoE endpoints, including common PoE devices like IP cameras and access control equipment, as long as those devices are compatible with the PoE/PoE++ power levels and Ethernet connection requirements.
Is it a good alternative to replacing my switch with a PoE++ model?
It can be a good alternative when you only need PoE++ for a limited number of endpoints and you want to keep using your existing non-PoE gigabit switch. If you need many powered ports, a PoE++ switch may be simpler.
Is there anything special about installation?
It is designed for straightforward inline installation. Reviews commonly describe quick setup, and the metal enclosure plus wall-mount approach helps with placement near racks or along the cabling route.
