Description

Overview

DC step-down module that converts a 20–90V battery input (via XT60, XT90 or EC5, or a 5.5×2.1mm jack) into a 5V USB output with dual Type-C ports supporting PD65W and QC3.0/QC2.0. Intended to power phones and laptops directly from an e-bike or large lithium pack.

Specifications

  • Input voltage: DC 20–90V
  • Input connectors: XT60 male/female, XT90 male/female, EC5 male/female, or 5.5×2.1mm jack
  • Output: 5V USB with dual Type-C ports
  • Fast charging: PD65W, PD/QC3.0, QC2.0
  • Function: step-down (buck) converter with integrated charging ports

Purpose

An e-bike or large lithium pack holds far more energy than a phone battery, but its voltage is unusable directly. This module taps that pack and produces a regulated 5V with fast-charging negotiation, effectively turning the vehicle into a high-capacity power bank.

Applications

  • E-bikes and e-scooters — phone and laptop charging on the move
  • Large lithium packs used as portable power
  • DIY power stations and field charging
  • Camping, touring and remote work setups

How to Use

  1. Confirm your pack voltage is within the 20–90V input range before connecting.
  2. Choose the input connector variant that matches your battery.
  3. Observe polarity strictly — reversed input will destroy the module immediately.
  4. Mount the module where it is protected from moisture and vibration.
  5. Use a PD-capable cable for 65W output; a standard cable will charge at a slower rate.
