The go-bag is not supposed to be elegant. It is supposed to be there when cell service is down, power is flaky, and you do not want to remember where the cable went.

Hardware Selector

Heltec Wireless Tracker

Great if you want GPS and a screen in one compact device.

Amazon search

Heltec V3 plus small antenna

Simpler and often slightly better on runtime if you do not care about onboard GPS.

10,000mAh power bank

The standard starting point for a lightweight kit.

Amazon search

20,000mAh bank

Worth it if the bag will support multiple devices or longer outage windows.

Small dry bag

Good for flood-prone or storm-heavy storage conditions.

Amazon search

Label card

Add a printed card with your device name, local channel notes, and the date you last charged the pack.

Foldable 915MHz antenna

Nice if the device will live packed most of the time.

Emergency whistle

Low-tech tools still matter when comms are degraded.

Packing Logic

Keep one cable attached

Do not make your outage workflow depend on finding the correct USB cable in the dark.

Pre-pair the phone

First pairing should happen on a calm afternoon, not in the middle of a storm.

Use a checklist card

Battery date, channel name, and node name should live in the bag, not just in your memory.

Setup Drill

  1. Flash and configure the node with your normal region and naming.
  2. Pair it to the phone you will actually carry.
  3. Put the node, cable, power bank, and printed reference card in the bag.
  4. Once a month, power the kit on for a two-minute readiness drill.
  5. Update the charge date after every drill.
Family-scale idea: Build two matching kits on the same private channel. A single prepared household node is useful. Two prepared nodes are a communication plan.

Readiness Questions

Could someone else in your house use this bag?

If not, add a printed reference card and simplify the contents.

Is the bag really charged?

If you do not run a monthly drill, you do not actually know.
