The average travel bag is full of redundant chargers: one for the laptop, one for the phone, one for earbuds, plus the cables and the brick that came with each. It does not have to be that way.

Modern gallium nitride chargers pack more power into a smaller brick, and a good power bank covers the times when there is no outlet at all. This is the two-piece setup that replaces the drawer of adapters.

A multi-port GaN charger is the backbone. One compact brick charges a laptop, phone, and earbuds at once, and folds flat for a bag. The only real tradeoff is that total output is shared across ports when everything is plugged in at the same time.

Portable Power Bank

Best value

Best for: Keeping phones charged through travel days

Pros
  • High capacity in a slim body
  • Fast charging in both directions

  • No built-in cable

A high-capacity power bank covers long days away from an outlet. Look for fast charging in both directions, so the bank itself refills quickly overnight. It is heavy for a pocket, but it lives in the bag, not the pocket.

The cables that survive

  • One long USB-C cable for the laptop and phone
  • One short cable for the power bank
  • Skip the cable for every single device - two good ones beat six cheap ones

Frequently Asked Questions

What is GaN, and why does it matter?

Gallium nitride lets chargers run cooler and more efficiently, so the same wattage fits in a much smaller brick than older silicon chargers.

Can one charger really charge a laptop?

Yes, if the charger outputs enough wattage, typically 65W or more for most ultrabooks. Check your laptop’s USB-C charging requirement.

How big a power bank do I need?

For a full travel day, 20,000 mAh is a good balance of capacity and weight, enough to fully recharge a phone several times.
