How to Keep Laptops Charged When Power Is Unreliable

A café in Wellington unplugged me mid-deploy because someone needed the outlet for a blender. I packed up without a speech. Power is part of the toolchain. If you only plan for gadgets as objects, you will still die at 12% in a room that was never yours.

Know the wattage. USB-PD that can actually feed the laptop, not a phone brick wearing a laptop-shaped hope. A 30W charger that “works” by draining the battery slower is not a charger. I carry a GaN brick that can do laptop plus phone from one wall, and I know which ports on it are the honest ones. Underpowered bricks fail politely until a meeting.

The power bank is for the gap between walls. Cafés that unplug you. Airports with two outlets and a queue. A house in a storm season where the lights flicker and the router reboots. I treat the bank like a rollback: use it before 5%, not as a personality after you already panicked. Capacity in watt-hours, not marketing mAh on a package aimed at phones.

Adapters are boring and they are the job. Aotearoa and Australia share a plug family. The rest of a Louisiana-to-elsewhere life does not. A small strip that turns one hostel socket into two, with surge protection you would trust in thunder, is more useful than a third novelty cable. Test the kit at home. A dead adapter in a new country is a calendar incident.

This is not a gadget list. I am not ranking backpacks or keyboards. I am talking about the moment the wall disappears and the work does not. Unreliable power is weather, old buildings, shared kitchens, and people with blenders. You cannot charm any of that.

I keep the brick in the same pocket every time so I do not leave it in a room. I charge the bank on the good nights, the way you charge a phone before a dawn flight. Louisiana summers taught me that electricity is a rumor some afternoons. Auckland is steadier, until it is not, and the café still has a blender. Plan for the unplug.
