4 mm Magnetic Smartwatch Charger

The ETEIZU cable delivers power to smartwatches that use a 4 mm pin spacing through a strong magnetic connection. It carries ROHS and CE certification and includes short-circuit, over-voltage and over-current protection to guard the battery during every charge. The one-metre Model A and 60 cm Model B cables have opposite polarities so at least one matches the watch when the spacing is correct.

Universal Fit for 4 mm Pin Spacing

This charger suits owners who have confirmed their watch uses a 4 mm gap between charging contacts and want a single purchase that covers both polarity options. It is not for buyers whose devices use a different pin spacing or a proprietary dock that cannot accept a magnetic USB cable.

4 mm Pin Spacing Requirement

The decisive specification is the 4 mm distance between the two charging points on the back of the watch. Measure that gap before ordering; only watches with exactly 4 mm spacing will connect reliably with either Model A or Model B.

Questions about this item

Should I pick Model A or Model B for my smartwatch?

Both cables share the same 4 mm pin spacing; they differ only in polarity. At least one will match your watch, so ordering the pair covers either orientation.

What does the 4 mm pin spacing mean when I connect the charger?

The magnetic contacts will only align if the distance between your watch's two charging points is exactly 4 mm. Measure the back of the watch before ordering.

Does the USB plug follow a specific charging standard that limits power?

The cable uses a standard USB-A connector and includes short-circuit, over-voltage and over-current protection, so it will deliver only the current your watch requests.
