Our verdict

A do-everything power bank that punches above its price — enough wattage for a laptop, enough capacity for a weekend.

The VoltCore hit its rated output in our tests, restoring a 13-inch laptop from empty to usable in about an hour. Two USB-C ports plus a legacy USB-A mean it charges nearly anything in your bag at once.

At around 340 grams it's not featherweight, but that's the trade for laptop-class output. Passthrough charging and an honest LED gauge round out a power bank that's hard to fault for the money.

What we liked

  • 65W output tops up most laptops
  • Passthrough charging while plugged in
  • Clear four-LED capacity readout

Worth noting

  • Heavier than pocket-sized banks
  • Cable included is short

Keep comparing
