Product 1
REVOTECH 12V PoE Splitter for CCTV and Cameras
This splitter converts 48V PoE to a 12V/2A DC output using a 5.5×2.1mm connector. It supports Gigabit Ethernet and auto-detects appropriate power, supplying up to 24W for devices with DC input. Best for security cameras and CCTV setups that require a stable 12V power supply from PoE. Limitations include a 12V output, which may not suit devices needing higher or different voltage rails.
Why this is best for
Best for security cameras and CCTV systems that accept 12V power from PoE networks. The 24W ceiling supports many common cameras without extra adapters, and the Gigabit compatibility ensures data stays fast.
Limitations
Not suitable for devices requiring non-12V PoE or higher current than 2A. Ensure your camera or device accepts 12V DC input.
Buyer’s Notes
- Best for: 12V camera deployments where 48V PoE is readily available.
- Better for: High-speed networks with cameras located far from a power outlet.
Product 2
TIENFOKOTA POE to USB-C Power Converter
This adapter converts PoE into USB-C power (DC 5V, up to 2.4A, 12W) with a data-capable Ethernet passthrough. It is IP65-rated for outdoor or damp environments, and includes a waterproof four-piece set to protect connections. It is best for powering USB-C devices such as security cameras or tablets from a PoE switch without separate power bricks. Caution: data transmission is not supported on this model, only power via USB-C is provided.
Why this is best for
Better for USB-C powered cameras or devices that require a compact, waterproof power solution from PoE, especially where outdoor exposure is a factor.
Limitations
No data transmission through USB-C; use separate Ethernet for data if needed.
Buyer’s Notes
- Best for: Outdoor deployments needing IP65 protection and USB-C power.
- Choose this if you primarily need power from PoE to a USB-C device without data transfer.
Product 3
PLUSPOE 48V to 30W PoE Injector
This injector enables non-PoE ports to power PoE devices with up to 30W, using 10/100Mbps. It supports IEEE 802.3af/at and provides protection against short circuits, over current, and over voltage. Best for legacy network gear or devices requiring PoE power over longer distances, but data speed is limited to 10/100Mbps. Use this when you need to extend PoE power to older equipment.
Why this is best for
Best for upgrading non-PoE IP cameras or phones that do not have built-in PoE, especially when data speed needs are modest.
Limitations
10/100Mbps data only; not ideal for gigabit networks or high-bandwidth cameras.
Buyer’s Notes
- Best for: Older network devices needing PoE power over longer runs.
- Better for: Scenarios where 30W is sufficient and gigabit data is not required.
Product 4
REVOTECH PoE to USB-C Adapter Converter
This device converts 48V PoE to a 5V/2A USB-C output plus Ethernet data, enabling a simple plug-and-play setup for PD charging and data. It aims for stable networks with minimized delay, making it suitable for live streaming or real-time monitoring. Best for smartphones, tablets, or USB-C devices that require both power and data access from a single PoE source. Limitation includes compatibility concerns with devices that demand higher than 5V/2A or non-USB-C power delivery.
Why this is best for
Best for USB-C devices needing both reliable power and network connectivity from a PoE source, simplifying cable management in modest power applications.
Limitations
Not suitable for high-wattage USB-C devices beyond 5V/2A or devices requiring more robust PD profiles.
Buyer’s Notes
- Best for: PD-capable USB-C devices in space-constrained setups.
- Choose this if you want combined power and data over a single Ethernet-cable approach.

It supports 802.3af/at and is designed to power devices like cameras and Raspberry Pi setups when used with compatible PoE equipment. Best for users building higher-performance PoE networks requiring 1 Gbps data alongside power. A caveat is ensuring your device is PoE-capable to avoid damage or non-functionality.
Why this is best for
Best for developers or hobbyists who need reliable 802.3af/at PoE power with gigabit data to support cameras or small servers.
Limitations
Must pair with PoE-enabled devices; older hardware may not support gigabit speeds.
Buyer’s Notes
- Best for: High-speed PoE deployments with power and data benefits.
- Choose this if you require a rugged injector for gigabit networks.
Buying Guide
Key purchase considerations help match a PoE-to-AC solution to your setup. First, identify your device’s voltage and current needs. Some adapters deliver 12V, others 5V via USB-C; ensure the output matches the device’s input. Next, decide on data requirements. If you need data and power over one cable, choose a PoE to USB-C or injector with both power and data. For outdoor or damp environments, look for IP-rated enclosures or waterproof accessories. Consider distance and cable length: longer runs require PoE capable switches or injectors with adequate wattage. Finally, verify compatibility with your existing PoE standards (IEEE 802.3af/at) to avoid underpowered devices or damage.
What to check when comparing
- Output voltage and current
- Data pass-through capability (Ethernet) and speed
- Protection features (short circuit, over-current, over-voltage)
- Environmental ratings (IP65, waterproofing)
- Maximum power budget (W)
Frequently Asked Questions
- What is PoE and why would I use a PoE to USB-C adapter? — PoE powers devices over Ethernet and a PoE to USB-C adapter lets you run both power and data to USB-C devices without separate power adapters.
- Can I power a Raspberry Pi with PoE? — Yes, if using a PoE splitter or injector that outputs 5V via USB-C or compatible 5V DC, depending on the Pi model.
- Do I need IP65 waterproofing for outdoors? — It’s recommended for outdoor installations to protect connectors from moisture and dust.
- Will a PoE injector work with any non-PoE device? — It can power PoE-enabled devices; non-PoE devices may not recognize the power supply or could be damaged if connected improperly.
- What does IEEE 802.3af/at mean? — They are PoE standards; af is up to 15.4W per device, at up to 30W per device, enabling higher power delivery for demanding devices.
