StarTech.com Secure Charging Cable — 1 m, USB-A to Micro-B, Data Blocker, 5 V 2.4 A
No data pins — physical block5 V, 2.4 A (12 W)Rugged TPE jacketLifetime warranty
The StarTech.com Secure Charging Cable, product ID USBSCHAU1M, is a 1 m black USB-A to Micro-B lead with the data pins physically absent. It is a charge-only cable by construction, not by software: there is no data path at all, so a device charging from an unknown USB port — an airport charging bar, a hotel desk, a hire car, a conference table, a colleague’s laptop — cannot exchange data with whatever is on the other end. That closes the “juice jacking” class of attack in the simplest possible way. It delivers 5 V at up to 2.4 A (12 W) through 22/32 AWG stranded copper, in a rugged TPE jacket with aluminium-mylar foil and a drain wire and nickel-plated contacts. A cut-away section in the connector shows the power-only wiring, so the cable can be visually identified as secure. StarTech.com backs it with a lifetime warranty. Typically in stock with fast delivery across Cyprus.
Compatibility — check before buying:
The point of this cable is what it cannot do: it carries no data. It will not sync, back up, transfer photos, tether, flash firmware or let a computer see the device at all — if the device appears to be charging but never shows up on the host, that is the cable working as designed. Two practical consequences. First, some devices negotiate faster charging over the data lines; with no data path this cable delivers standard 5 V at up to 2.4 A, so a proprietary fast-charge mode may not engage. Second, the connector is the standard 5-pin Micro-B — not USB-C, and not the wider 10-pin USB 3.0 Micro-B. The USB-A end works with any host port, wall charger or power bank. Operating range is -20 °C to 60 °C at 10–80% RH.
Key Features
Data pins physically absent, not disabled
There is no software, no chip and no setting to get wrong — the conductors simply are not there. That is a stronger guarantee than a data blocker dongle a user might forget to fit, and it cannot be bypassed by a malicious host.
Closes the public-charging attack surface
Public USB charging points are an untrusted host as far as a phone is concerned. A power-only cable means an unknown port can supply current and nothing else, which is the recommended practice in corporate, government, defence and education environments — and sensible anywhere staff charge devices in airports and hotels.
5 V at 2.4 A (12 W)
Enough current for a phone, tablet, headset or camera at a normal rate. The 22 AWG power conductor is what supports 2.4 A over a metre without meaningful voltage drop — thin-gauge charge cables are where that current quietly disappears.
Cut-away connector shows the power-only wiring
A visible window in the shell exposes the two power lines and the absence of data lines. In an organisation issuing secure cables, being able to identify one at a glance — rather than trusting a label — is the difference between a policy and a practice.
Rugged TPE jacket with foil and drain shielding
TPE is more resistant to fraying and abrasion than PVC and stays flexible when cold, which suits a cable that lives in a bag. The foil-plus-drain shield keeps interference from the power line down in electrically noisy public charging installations.

Frequently Asked Questions
Singular Expert Insight
Charge-only cables are a small, cheap control that closes a specific hole, and the reason to buy a physically power-only cable rather than a blocker dongle is behavioural rather than technical. A dongle protects you when you remember it; a cable with no data conductors protects you always, and it cannot be defeated by an untrusted host. That makes it the right issue item for staff who travel, and the right thing to leave in a meeting room or a vehicle. The trade-offs are honest and worth stating: no syncing at all, and no proprietary fast-charge negotiation, so it delivers a straightforward 5 V at up to 2.4 A. The cut-away window is a more useful detail than it looks — in a drawer full of black Micro-B cables, being able to see that a cable is the secure one is what keeps the policy working. Browse our docking stations range for the USB-A ports it plugs into, and see our USB flash drives section for other USB accessories.
Buyer's Guide
Buy it if
You or your staff charge Micro-B devices from public, shared or untrusted USB ports and you want the data path physically removed rather than relying on a dongle or a habit.
Skip it if
You need to sync or transfer data, or you rely on a proprietary fast-charge mode that negotiates over the data lines. Also skip it if your device uses USB-C.
Also consider
StarTech.com secure charging cables with USB-C or Lightning connectors, standard Micro-B charge-and-sync cables for desk use, or USB data blocker adapters for cables you already own.
