Overview
HELLEE makes this black lithium polymer power bank with several cables built in, so none have to be carried separately. A digital display shows the status, and the output is aimed at iPhone and Samsung phones. The listing also names headphones, laptops and speakers.
The reason to buy is the cable-free carry and the display. The limit is that output per port is not broken out and the warranty term is missing.
Who it's for
Commuters and travelers who charge phones, earbuds and speakers. Laptop users should look for a higher output pack.
Pros and cons
- Fast charging figure listed
- Many phones listed
- Warranty term missing
- Per-port output not listed
- Cable types are not itemized
Performance notes
Fast charging reaches the stated half-charge time only on a phone that supports the matching protocol. Ports share the total output, so more devices at once means a slower rate for each.
