Our verdict

A large power bank with a built-in USB-C cable and enough output for a laptop, phone or Switch. It is heavy at over fifteen ounces, so it suits a bag rather than a pocket.

Overview

A laptop-carrying commuter or traveler gets a large capacity pack with a cable built into the body and two more ports. The pack recharges phones, tablets and even laptops away from a wall outlet.

The built-in cable removes one thing to forget, and the output is high enough for a MacBook. Weight and size make it a bag item. The listing is short on the exact port wattage split.

Who it's for

Frequent travelers, students and remote workers who charge a laptop or Nintendo Switch away from outlets. Phone-only users will carry more weight than they need.

Pros and cons

Pros
  • Built-in USB-C cable
  • High maximum output
  • Fast charging figure listed
Cons
  • Heavy for a pocket
  • Port wattage split not given
  • Warranty unit not stated

Performance notes

The high capacity supports several phone charges or a partial laptop charge. Output is shared across the three ports, so using all of them lowers what each device draws. Heavy loads, such as a laptop, drain the pack much faster than a phone.
