The PowerPass PP4020 Mini HDBaseT Extender delivers extra quality 4K signal extension in the smallest possible footprint. Designed for professional AV installers, home theater enthusiasts, and corporate environments, this set (transmitter + receiver) extends HDMI up to 70m (230ft) at 4K/60 and up to 100m (328ft) at 1080p – all over a single CAT6/6a/7 cable.

True to its “Extra Quality” badge, the PP4020 maintains full HDCP 2.2 compliance, supports HDR10, Dolby Vision, and passes multichannel audio (up to 7.1CH, Dolby Atmos, DTS:X).


Myth 1: "It's just an expensive power strip." Reality: A $20 power strip has a single thermal fuse and stamped brass contacts. The PP4020 has four hydraulic-magnetic breakers, a copper bus bar, and a welded steel chassis. It’s like comparing a bicycle to a pickup truck.

Myth 2: "Extra Quality just means better packaging." Reality: The "Extra Quality" designation involves component-level upgrades—better connectors, thicker internal copper, and 100% factory load testing at 125% of rated amperage.

Myth 3: "I can plug this into a 15-amp wall outlet." Reality: Technically yes, but you then limit the total draw to 15A. The PP4020 is optimized for 20A circuits with a NEMA 5-20 plug (one blade turned sideways). Use a current-limiting adapter with extreme caution.

The "Mini" in the product name is not just marketing fluff; it is a solution to a specific pain point. As buildings become smarter and technology stacks grow, the space behind walls and inside conduit runs becomes premium real estate.

The PP4020 is engineered with a low-profile footprint specifically to fit into standard UK back-boxes (such as a 25mm or 35mm dual gang) alongside other equipment. This compact design simplifies the "spaghetti mess" often found behind wall-mounted TVs or distributed audio nodes. By reducing the volumetric footprint, PowerPass allows for better cable management, which in turn prevents sharp bends that can degrade signal integrity over time.

I tested the PP4020 Mini HDBIN Extra Quality in a demanding scenario: powering four JBL SRX828SP subwoofers during a 4-hour outdoor hip-hop show. Each sub can draw up to 10A peak, but realistically hovers around 6A continuous. Total potential draw: 24A (over the 20A limit).

Standard units often use generic, brass-based outlets that loosen over time. The Extra Quality version features nickel-plated, high-retention outlets (often from brands like Leviton or Hubbell). These provide superior grip on your equipment’s plugs, reducing vibration-induced dropouts—a common issue on subwoofer-heavy stages or mobile broadcast trucks.
