Micro USB

The MOS Spring Micro USB cable gives your device the cable it deserves, both in terms of style and durability.

The MOS Spring takes USB cables to a whole new level of design and quality. The Spring cable features only the best materials to ensure this would be the only Micro USB cable you will ever need to buy. We’re so sure of this that we are offering a lifetime warranty on every MOS Spring cable we sell.

Introducing the 2nd gen MOS Spring

No detail was too small during the development of the second generation MOS Spring cables.

The MOS team is constantly improving even the most intricate details of their products. The Spring cables were designed to be the best cables in the world, but these second generation cables move them to a whole new realm.

Here at MOS we love form and we love function, yet we really don't like to compromise. The MOS Spring gives you both in a way no one else can.

Anodized Aluminum Housing


The lightweight yet extremely durable housing protects the sensitive internal circuitry. The anodized aluminum heads offer a scratch resistant surface, minimal weight, premium look and feel, laser-engraved logos and tough protective housing.

Durable Housing

Carbon Blackened Steel Spring


The steel spring adds strain relief just where it is needed most. The spring is composed of unique carbon blackened steel so the color never flakes or fades. The ferrous metal also works great with our MOS cable organizers.

Spring Relief

Woven Exoskeleton™ Jacket


Multiple layers are utilized for unrivaled build quality. Exoskeleton™ is a proprietary woven jacket offering maximum protection. High-grade TPE polymer wraps the inner wires for even further protection, but truly excels for its great flexibility.

Pros: The MOS Spring micro USB cable is meant to accompany the MOS magnetic cable organizer. The cable features some great things, such as springs at the ends to prevent cable fraying and bending, as well as a cable housing that is more durable, being called an “exoskeleton woven jacket” by MOS. This is the first cable I’ve experienced that might truly hold up to constant use and transport in bags, backpacks, etc. The packaging of the cable is very minimal. It comes in a clear bag with some information on the back side. No frills, nothing unnecessary - this is how packaging should be. The feel of this cable is quite different than the norm. The housing has a slightly rough texture to it, and the ends of the cable, being spring loaded, are very resistant to being bent, which is great. You can throw this cable in any bag without fear of the connector getting bent at its endpoint. The MOS feature (magnetic) of the cable works very well. The metal attaches very strongly to the magnet in the MOS, so your cable stays securely attached. Pulling it off for use is as simple as a small tug. If any of you have a MacBook, it feels as strong as the MagSafe charger when it attaches to your MacBook. The MOS Spring micro USB Cable is in my opinion an essential addition to anyone’s collection of cables. It’s durability is unmatched. This truly might be the last micro USB cable you’ll ever need to buy.

Cons: See Pros section for my full review!

Amazing charger

Patrick - 1/14/2017 8:57:06 AM

I bought the 6ft cable and it's amazing. It lasted well over 3 years and when it broke, It was hard getting used to using my normal 3ft charger. When it broke, I just contacted the support and they gladly sent me a new one really quickly! I've never experience such a great support from anyone before and having a lifetime warranty backs up this charger too.

This product is awesome. I had purchased one from someone else and it stopped working. This cord is awesome and works great. And does what it says it will do and it's very flexible.
