PowerVerify AirGap — Transparent USB-C Data Blocker (Pre-Order)

You shouldn't have to trust your charger.

The FBI has warned travelers about "juice jacking" for years. Public USB 
ports can install malware or steal data. Every cheap data blocker asks 
you to trust it.

PowerVerify AirGap lets you verify it.

Look through the clear heatshrink. You can see there are no data lines. 
No hidden chips. No firmware. No software. Only power can flow — because 
data physically cannot.

What you're buying

A short-pigtail USB-C power cable, approximately 90mm long, with the 
working board visible through clear heatshrink. The USB-C receptacle 
on the charger end is a 6-pin power-only connector — meaning the data 
pins don't exist in the plastic housing at all. You can count the pins 
yourself: 6 instead of the 24 on a normal USB-C.

What it does NOT have

• No data lines. None. The connector has no data pins. The pigtail has 
    no data wires. There are no data traces on the board.
  - No firmware. This is a physical cable, not a device with software.
  - No hidden chips. You can see every component through the clear 
    heatshrink.
  - No cloud dependency. Works offline, forever.
