Overview

The Monoprice AtlasFlex 138335 is a USB 2.0 Micro B to Type A cable built for users who are tired of replacing cheap cables that fray and fail. At its core is Kevlar fiber reinforcement — the same material used in body armor — wrapped in a tightly woven nylon braid that resists tangling, kinking, and everyday wear. The connectors are housed in reinforced aluminum shells that withstand repeated plugging and unplugging far better than the plastic housings found on most budget cables.

At six feet in length, the AtlasFlex strikes a practical balance between reach and manageability, making it well-suited for bedside charging, desktop use, or connecting devices to a laptop. It carries both power and USB 2.0 data, so it works equally well for syncing an e-reader, charging a Bluetooth speaker, or connecting a game controller. While USB Micro B is gradually being phased out in favor of USB-C, many devices — from older phones to portable electronics — still rely on it, and this cable ensures those connections remain solid and dependable for the long haul.

Key Features

Premium charge and sync: keep any device with a Micro USB type-B input fully charged and synced with your favorite photos and music.

High-strength aluminum connectors: Designed to withstand forces up to 30 lbf (130N), these aluminum connectors were engineered to defy the rigors of odd bends and strains. It will take a force greater than 130N to get these connectors to even begin to bend.

Resilient and flexible strain reliefs: built with repeated use in mind, These cables have longer and more flexible strain reliefs to ensure that the point where the cable Meets the connector does not fail.

Nylon and Kevlar reinforced cable: the nylon-wrapped, Kevlar-reinforced cable allows for heavy use without any connection issues or failures. Despite twists, tweaks, or turns, these cables will never let up.

Each cable is fitted with reinforced, robust aluminum connectors to withstand any and all bends, drops, pulls, and mishaps.
