Critin 30 Pin Charging Cable for iPhone 4/4S, 3G/3GS, iPad 1/2/3 — USB Sync & Charge (1m)

What it is

The Critin 30 Pin Charging Cable is a USB 2.0 charger and data sync cable designed for older Apple devices that use the 30-pin dock connector. It’s compatible with iPhone 4/4S, iPhone 3G/3GS, iPad 1st–3rd generations, iPod nano and iPod touch models within the 30-pin ecosystem. The cable ships at a practical 1 metre length, offering flexibility for desktop, bedside or lounge use, without being overly long.

What it’s for

This cable is intended for users who still rely on legacy Apple hardware and want a single, reliable accessory for charging and transferring data. If your setup includes older iPhone, iPad or iPod models, this cable provides a straightforward, no-hussle solution to keep those devices connected to modern USB chargers and computers.

Key features

On the bench, the cable prioritises practical usability over flashy tech. It uses pure copper wire and PVC insulation to support data transmission and charging. The connector is gold-plated, which helps combat oxidation and corrosion and should resist repeated plugging and unplugging. The design is aimed at stable charging up to around 2.1A, while allowing syncing tasks such as photos or videos to be carried out via USB.

What stands out day to day

The 1 m length is handy for placing a device on a desk or nightstand while still reaching a wall outlet. The 30-pin dock compatibility covers a broad range of older Apple hardware, reducing the need for multiple cables. If you’ve previously used third-party 30-pin cables, you’ll likely recognise the convenience of plug-and-play data transfer and charging performed through a single lead.

What you’ll notice in use

Expect good compatibility with devices that use the 30-pin connector and USB 2.0 charging. The cable supports data transfer and charging simultaneously, which is useful when you want to back up or sync content while charging. If you prioritise fast charging for older hardware, note that the stated maximum is 2.1A—not all setups will push that limit, and real-world speeds depend on both the device and charger used.

Limitations and who it’s not ideal for

Not compatible with newer Apple devices that use Lightning or USB-C connectors, nor with older iPod models outside the listed generations. For users who regularly work with current iPhone or iPad models, this is a niche purchase that won’t replace a modern cable. If you need higher durability or mil-spec build for rigorous daily use, this cable may not satisfy those higher expectations.

Before you buy: practical checks

• Confirm your device uses a 30-pin dock connector and that you have a compatible charger or computer port.
• Consider your preferred charging speed, while 2.1A is supported on paper, real speeds depend on the charger you pair with.
• Compare the 1 m length with your typical setup to ensure reach without excess slack.

How it compares to alternatives

If you’re deciding between this 30-pin solution and newer cable types, the choice largely depends on your hardware. For legacy devices, this cable keeps functionality without investing in adapters or revamped accessories. For those embracing newer ecosystems, a Lightning/USB-C route will be more future-proof, but with an obvious upfront difference in device compatibility.

Decision time

Is it worth it?

It makes sense if you’re keeping one or more older Apple devices alive and you want a straightforward, reliable 30-pin charging and syncing cable in a single, modestly long lead.
