Cheaper AliExpress alternatives to the Magnetic 2 Pin Power Cable

Not exactly. GreatScott! reviewed a finished magnetic power cable assembly; this AliExpress listing is the bare spring-loaded connector pair that would sit inside such a cable. It covers the same functional concept — magnetic DC connection — but arrives as an unsoldered PCB component, not a ready-to-use cable. Buyers who want the finished item should search specifically for a 'magnetic power cable' listing rather than raw pogo pins.

The listing specifies a 2A continuous current rating, which supports up to roughly 10W at 5V — adequate for slow charging or low-power DC applications. It is not a USB-C PD connector; there is no USB-C physical interface or PD negotiation circuitry. If your project needs USB-C PD fast charging (18W+), this component is not the right choice.

In principle, yes — the 3, 4, 5, and 6-pole variants provide additional contacts that can carry low-speed data, I2C, UART, or ground lines alongside power. However, the listing does not specify contact resistance or signal integrity ratings, so high-speed data (USB 2.0 480 Mbps or above) is not confirmed. Low-speed sensor or control signals are the realistic use case.

The listing title includes the word 'waterproof,' but no specific IP rating (such as IP67 or IPX5) is stated in the product description. For applications exposed to splash or brief submersion, ask the seller for test data before committing. Do not assume full submersion tolerance based on the marketing label alone.

The listing states a 2A current rating but does not clearly specify a maximum voltage. Pogo-pin connectors of this physical size are typically rated for low-voltage DC (5V–24V), but exceeding the contact's rated voltage or current risks arcing and contact damage. Confirm the voltage rating with the seller if your circuit runs above 12V.

The $1.32 price appears to reflect a single male-female pair at the selected pole count; the listing offers 2, 3, 4, 5, and 6-pole options, and price may vary slightly by pole count. Verify the quantity in the listing before ordering — some component listings ship a set of five or ten pairs, while others ship one. Check the product variants tab carefully.
