EverStar iPoE-24W48DW 100Mbps PoE Injector - 24W 48V DC

Our review of the EverStar iPoE-24W48DW finds it is a practical, no-nonsense PoE injector aimed at installers and small-site integrators who need reliable DC-to-DC PoE from battery or solar systems. The standout reason to consider it is simple: it converts a wide 9-36V DC input to a regulated 48VDC PoE output at up to 24W while keeping a compact, mountable package. That combination makes it particularly useful where 12V or 24V batteries power wireless access points or IP cameras and where a hardened, protected injector is preferred over using local AC supplies.

Key Features

• Wide input range: Accepts 9-36V DC so it can be used with 12V or 24V battery banks and many solar setups without additional converters.
• 48V, 24W PoE output: Delivers up to 24W on 48VDC to power mid-power wireless radios and cameras that require passive Mode B pair wiring.
• Gigabit-capable pairs: Two 100Mbps Ethernet ports (one in, one PoE out) provide full duplex 200Mbps throughput between device and network for typical surveillance and wireless gear.
• Protection features: Built-in short circuit, overvoltage and overcurrent protection helps protect both source and powered device in field installations.
• Flexible mounting: Tool-less interlocking snap slots and options for desktop or wall mount make installations neat and scalable for multi-unit deployments.
• Service-friendly input: The 3-pin barrier terminal DC input simplifies wiring to battery or solar controllers for technicians on site.

Who It's For

This injector is aimed at network technicians, CCTV installers, and rural wireless integrators who run equipment from 12V or 24V battery systems or solar arrays and need a compact DC-DC solution. It is particularly well suited for powering Ubiquiti and Cambium client devices and many solar CCTV cameras that accept passive Mode B PoE on pairs 4,5 and 7,8.

Those who should look elsewhere include installers who require active 802.3af/at negotiation or higher power budgets above 24W, and environments that demand industrial temperature ranges beyond -30C to 45C or hardened outdoor-rated enclosures without additional protection.

Pros & Cons

Pros

• Compact DC-DC design that works across 9-36VDC inputs for flexible battery or solar use.
• Delivers regulated 48VDC at up to 24W using passive Mode B wiring for many radios and cameras.
• Includes short circuit, overvoltage and overcurrent protection for safer field operation.
• Easy mounting and tool-less snap slots allow linking multiple units cleanly.

Cons

• Uses passive Mode B PoE and not 802.3af/at negotiation, which limits compatibility with some devices.
• Operating temperature tops at 45C, so extreme-heat outdoor sites may need extra housing.

Our Verdict

The EverStar iPoE-24W48DW is a focused DC-DC PoE injector that delivers dependable 48V/24W power from 9-36V sources and useful protections in a compact, mountable package. It offers clear value for CCTV installers and wireless technicians who need passive Mode B PoE from battery or solar systems, though those needing negotiated 802.3af/at support or higher power should consider other options.

Frequently Asked Questions

Can this run from a 12V battery?
Yes, the unit accepts 9-36V DC input so it will run directly from 12V battery systems and 24V systems without an extra converter.

What PoE pinout does it use?
It supplies passive Mode B PoE on pairs 4,5 positive and 7,8 negative, so confirm device compatibility with that wiring.

Is it protected against faults?
Yes, the injector includes short circuit, overvoltage and overcurrent protection to protect the source and powered device.
