A PoE injector sends power and data over one Ethernet cable, so PoE cameras and access points need no nearby outlet.
This guide covers 6 PoE injectors sold on Amazon. It is built from the product listings, not our own testing, so confirm the details that matter on each product page. Prices were as listed on Amazon.com on October 31, 2026 and change often.

How to Choose
Standard and wattage
Match 802.3af or 802.3at (PoE+) to your camera and check the wattage.
Gigabit and ports
Gigabit injectors keep full speed, and multi-port midspans power several devices.
Price and brand
In this guide prices run from about $18.49 to $125.97. Lesser-known brands can be good value, but check warranty terms, return policy and recent reviews before you buy, and remember that listing titles are written by the seller.
How We Chose These Products
We searched Amazon for PoE injectors, kept results with a full product name, a visible price and a reasonable rating, and limited the list to one product per brand so that the choices differ. We did not test the products, and we skip results that show only a brand name. See how we pick products.
Common Mistakes to Avoid
- Choosing on the lowest price without reading what is included.
- Ignoring compatibility with your exact device or setup.
- Trusting performance claims in listing titles without checking reviews.
- Skipping the return window and warranty details.
