Introduction: The Question Everyone Asks

You’re working…

Your laptop battery drops to 10%

👉 No outlet
👉 No time
👉 No backup


👉 So you ask:

👉 Can a power bank charge a laptop?


👉 The answer:

👉 Yes—but only if it meets the right requirements


Why Most Power Banks Fail

Most standard power banks:

❌ Output only 10–18W
❌ Designed for phones
❌ Cannot sustain laptop charging


👉 Result:

  • Charging doesn’t work

  • Battery drains anyway


The 3 Requirements for Laptop Charging

👉 Minimum:

  • 45W (basic)

  • 65W (recommended)

  • 100W (best)
