What You Need to Charge a TI‑84 Plus CE

To charge your calculator, you’ll need:

  • A USB‑A to mini‑USB cable (included with the calculator)
  • A power source such as:
    • A computer or laptop USB port
    • A wall USB charger
    • A power bank

✅ No AA batteries are required—the TI‑84 Plus CE has a rechargeable lithium‑ion battery.

Step‑by‑Step: How to Charge the TI‑84 Plus CE

1. Locate the Charging Port

  • The charging port is on the top‑right side of the calculator
  • It uses a mini‑USB connector (not micro‑USB or USB‑C)

2. Connect the USB Cable

  • Plug the mini‑USB end into the calculator
  • Plug the USB‑A end into a computer, wall adapter, or power bank

3. Check the Charging Indicator

  • A battery icon will appear on the screen
  • The icon animates while charging
  • Once full, the battery icon stops moving

💡 The calculator can be on or off while charging.

How Long Does Charging Take?

  • Full charge time: ~4 hours
  • Battery life: Up to 10–14 hours of normal use
  • Standby time can last several days

Charging from a wall adapter is usually faster than charging from a computer.
