You should be able to prove it.\u003c\/h2\u003e\n\u003cp\u003ePublic USB ports and unknown cables can move data, not just power — the reason the FBI and FCC have both warned travelers about “juice jacking,” and why the FCC’s guidance is to use a charging-only cable from a trusted supplier.\u003c\/p\u003e\n\u003cp\u003eHere’s the problem with most “data blockers”: they ask you to trust that the data path is switched off. Software can be wrong. Switches can fail. You can’t see any of it.\u003c\/p\u003e\n\u003cp\u003ePowerVerify doesn’t switch the data lines off. \u003cstrong\u003eThey’re not there.\u003c\/strong\u003e As the device itself says: \u003cem\u003eWhen physics is policy, trust is optional.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch2\u003eDon’t trust it. Verify it.\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eSee it.\u003c\/strong\u003e Look straight through the clear, cast resin. No data traces, no chips, no firmware — three parts: a surge protector at each port and one bulk capacitor on VBUS, every one named on the board (\u003cstrong\u003eSURGE PROTECT\u003c\/strong\u003e, \u003cstrong\u003eSURGE PROTECT\u003c\/strong\u003e, \u003cstrong\u003eVBUS BULK\u003c\/strong\u003e). Both receptacles are \u003cstrong\u003esix-contact power-only USB-C parts\u003c\/strong\u003e: VBUS, ground, CC1 and CC2. There is no D+ or D− contact to be unwired — the metal is not there. The board says it in silkscreen: \u003cstrong\u003eDATA ABSENT.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProve it won’t talk.\u003c\/strong\u003e Put the coupler between your cable and the port: a computer on one side, your phone on the other. Your phone charges — and never appears as a USB device. No notification, nothing in Device Manager, nothing in System Information. It can’t enumerate, because there’s no data path to enumerate over. This takes thirty seconds and it doesn’t require believing a word we’ve said.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLook it up.\u003c\/strong\u003e Every unit carries a verification code — printed on the label sealed inside the resin. Enter the code at \u003ca href=\"https:\/\/verifyknot.io\/\" rel=\"noopener noreferrer\" target=\"_blank\"\u003everifyknot.io\u003c\/a\u003e to pull the manufacturing record for the specific unit in your hand.\u003c\/p\u003e\n\u003cp\u003ePower flows over VBUS and GND. CC1 and CC2 pass straight through from one receptacle to the other, so your charger and your device negotiate voltage with each other — there is no controller in between, and either end can be the source. The D+\/D− data contacts do not exist in either receptacle. Your charger can’t reach your device — not because the path is disabled, but because it was never built.\u003c\/p\u003e\n\u003ch2\u003eEvery claim is printed on the object, permanently\u003c\/h2\u003e\n\u003cp\u003eWe can revise this page. We can’t revise the board. So the construction is written on it, in silkscreen, where it can’t be quietly walked back: \u003cstrong\u003ePowerVerify™ · DATA ABSENT\u003c\/strong\u003e, and the name of every part beside it. On the reverse, under the pot: the sealed label with the unit’s verification code and \u003cstrong\u003ePOWER ONLY · DATA LINES PHYSICALLY ABSENT\u003c\/strong\u003e, and \u003cstrong\u003eZKNOT.IO\u003c\/strong\u003e. If we ever overstated this product, the evidence would be cast in resin in a customer’s hand.\u003c\/p\u003e\n\u003ch2\u003eBuilt as evidence, not as an accessory\u003c\/h2\u003e\n\u003cp\u003eEvery PowerVerify is a serialized object with a build record, not an anonymous adapter:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIt’s sealed in a \u003cstrong\u003esingle solid pour\u003c\/strong\u003e of clear resin — no seams, no screws, no shell to pop open.

The finish isn’t decoration. A pot you can’t see through can’t be inspected, and inspection is the entire product.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eStraight talk about what that record is\u003c\/h2\u003e\n\u003cp\u003eWe sell honest proof, so here is precisely what the record does and doesn’t do.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat it is:\u003c\/strong\u003e ZKNOT’s signed statement that we built this specific unit, and when. A birth certificate, signed at our bench with our provisioning key. A provenance trail you can look up instead of taking on faith.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat it is not:\u003c\/strong\u003e it is not a claim made \u003cem\u003eby the coupler.\u003c\/em\u003e This unit is passive — no microcontroller, no secure element, no key. It signs nothing, at the bench or in the field, and it cannot record or attest a charging session because it has nothing to record with.\u003c\/p\u003e\n\u003cp\u003eAnd it is not an independent third party vouching for us. That signature is ours. It proves the record hasn’t changed since we filed it. It does not prove we’re honest — nothing signed by us ever could. What it does is make our claim \u003cstrong\u003especific, dated, and checkable\u003c\/strong\u003e, so that if we ever lied about a unit, the lie would be a fixed target instead of a vague impression.\u003c\/p\u003e\n\u003cp\u003eThat’s the standard we hold everything here to.
