Compact: the essentials for travel or a light setup.

Why people pick it

  • Two USB-C ports at 140W each can fast-charge two big laptops at once, including a 16-inch MacBook Pro
  • 99.75Wh sits just under the common 100Wh carry-on limit, so it's as big as you can fly with without airline approval
  • Dual-port 250W input refills it faster than most chargers can supply
  • Includes a 240W cable, so the 140W output works out of the box

Know before you buy

  • At 600 g it's a bag item, not a pocket one
  • Anker says the 140W maximum is sustained only up to 80% battery level
  • Fast recharging needs one or two high-wattage chargers; 250W input means two 140W-class chargers
  • USB-A port tops out at 22.5W
