Wondering how to install a USB charger in a golf cart? Adding a USB charger to your golf cart is a smart and simple upgrade. It lets you charge your phone, GPS, or Bluetooth speaker on the go. Most golf carts don’t come with one built in. But the good news? You can do it yourself.

Here’s how to install a USB charger step by step.

What You’ll Need

  • USB charger port (12V or 48V, depending on your system)
  • Wire connectors
  • Fuse holder and fuse
  • Drill
  • Wire stripper/crimper
  • Electrical tape or heat shrink
  • Multimeter (optional, but helpful)

Choose the Right USB Charger

Make sure your charger matches your golf cart’s voltage.

Most carts are 36V or 48V. Some USB chargers can handle this directly. Others need a voltage reducer to bring power down to 12V.

Check your charger’s specs before installing.

Find a Mounting Spot

Pick a place near the dash or steering column.

You’ll want the charger close to where you sit for easy access. Make sure there’s enough room behind the panel for wiring.

Use a drill with a hole saw to make a clean cutout.

Wire the USB Charger

Direct to Battery

If you’re wiring directly to the battery, use the correct terminals.

  • Connect the positive wire (usually red) to the battery’s positive terminal
  • Connect the negative wire (usually black) to the battery’s negative terminal
  • Use an inline fuse holder on the positive wire for safety

Using a Voltage Reducer

If your USB charger needs 12V, install a voltage reducer between the battery and the charger.

  • Wire the reducer to the battery
  • Then wire the USB port to the reducer’s output
  • Follow the same positive/negative setup

Secure the Wiring

Use zip ties or wire clips to keep wires neat.

Avoid loose wiring that could snag or wear down. Secure everything behind panels when possible.

Use electrical tape or heat shrink to protect your connections.

Test the USB Charger

Turn on the golf cart.

Plug in a device to see if it charges. If not, double-check your wiring and fuse.

Use a multimeter to confirm voltage if needed.

Add a Finishing Touch

Many chargers come with a waterproof cap.

Install the cap to protect it from dust and rain.

You can also add a backlighted USB port for style and visibility at night.
