USB 5V 3A Power Cable with 8 Barrel Adapters

This cable converts a standard USB-A port into a 5.5 × 2.1 mm centre-positive DC barrel plug and includes seven additional interchangeable tips. It delivers up to 3 A at 5 V for a maximum of 10 W, making it suitable for routers, Bluetooth speakers, LED strips, USB hubs and similar low-voltage peripherals.

Buyers needing a single versatile lead

The eight tips cover 3.5 × 1.35 mm, 4.0 × 1.7 mm, 4.8 × 1.7 mm, 5.5 × 1.7 mm, 5.5 × 2.1 mm, 5.5 × 2.5 mm, 6.3 × 3.0 mm and 6.4 × 4.4 mm jacks, so one cable can replace several dedicated adapters. It is not for equipment that requires more than 5 V, draws above 3 A, uses a centre-negative barrel, or relies on a proprietary multi-pin power connector.

Fixed 5.5 × 2.1 mm barrel

The cable terminates in a 5.5 mm outer-diameter, 2.1 mm inner-diameter plug wired centre-positive; the seven extra tips snap onto this base. If your device uses a different fixed barrel size or opposite polarity, this lead will not connect correctly.

Questions about this item

Which connector size should I pick for my device?

The cable includes eight interchangeable tips: 6.4x4.4mm, 6.3x3.0mm, 5.5x2.5mm, 5.5x2.1mm, 5.5x1.7mm, 4.8x1.7mm, 4.0x1.7mm and 3.5x1.35mm. Match the tip to your device's DC jack dimensions.

What does the 5V 3A rating mean for my hardware?

It delivers up to 3 amps at 5 volts, so any 5V device drawing 3A or less — such as routers, LED lights or USB hubs — will receive its required current without overload.

What does the USB-A plug limit in practice?

The Type-A male USB plug connects to any standard 5V USB port or charger, capping the output at the source's maximum — typically 5V 3A (10W) — so the cable cannot exceed what the host port supplies.
