An emergency preparedness tech kit checklist is not about doomsday. It is about the Tuesday your street loses power for eleven hours, the storm that takes the local network down with it, and the fact that everything you normally use to solve a problem lives behind a screen that is now at 12%.
What follows is a practical list: light, power, information, and the containers that keep them working. Nothing here requires a bunker or a budget you will resent. The goal is simple — when the grid goes quiet, your household stays comfortable, informed and able to charge a phone.
Start with the boring truth
Most outages are short. The kit that actually gets used is the one that handles a few hours of darkness and a day without internet, not the one built for a scenario you will probably never see. Build for the common case first, then add depth if you live somewhere with a track record of longer disruptions.
That framing keeps the list honest. Everything below is ordinary consumer gear, stored where you can reach it in the dark.
1. Light: one per person, not one per household
The classic mistake is a single good flashlight for a family of four. In practice everyone needs to move around independently, and a shared torch means three people using phone screens and burning battery they will want later.
Powertac's Family Emergency Kit is built around exactly this logic. It packs four E11 Gen3 lights, one per family member, each a 2,020-lumen rechargeable EDC light with Type-C charging, five brightness modes plus strobe and an IPX8 waterproof rating, shipping with an 18650 rechargeable battery and cable. It adds four ten-packs of CR123A cells, forty batteries in total, as backup power that keeps its charge on a shelf.
If you would rather build it yourself, the criteria are: a rechargeable light with a spare cell, a usable low mode so you are not blinding the room, and a genuine water rating. Powertac's Storm Outage Kit takes the same idea toward longer outages, pairing the FlexBeam, a 1,200-lumen light with a rotating head that shifts from wide flood to tight spot, with two spare 18650 rechargeable batteries and a magnetic charging cable. We compared the bundles in our Powertac outage kit roundup.
Add a headlamp if anyone in the house will need both hands. Red light modes are worth looking for, since they preserve night-adapted vision and are far less disruptive if half the household is asleep.
2. Power: charge everything before you need to
Two habits matter more than any purchase. First, keep your power banks topped up rather than half-flat in a drawer. Second, own one charging setup that can refill several devices quickly during the windows when power is available.
A high-output desktop hub is the unglamorous hero here. The Titan Power+ 330W GaN PowerStation delivers up to 330W across ten ports, four USB-A at 18W each and six USB-C up to 100W, including two dedicated 100W USB-C ports for laptops. When the power comes back on for two hours before the next outage, that is the difference between refilling one device and refilling the whole house.
Cables deserve one line of thought too. A single 4-in-1 cable removes the risk of owning the wrong end for someone else's phone; the Titan PrismCore 240W cable carries USB-C, Lightning and USB-A connectors in one lead, with reinforced silicone and zinc alloy construction. And a tracker card in the kit bag, like the ultra-thin Titan Smart Tracker with Apple Find My integration, makes the bag itself findable.
3. Information: the part most kits forget
Light and power are the easy half. The harder problem is that almost everything you know how to do is stored on a server you can no longer reach. Repair instructions, maps, first-aid manuals, how to shut off a valve you have never touched — all of it is one outage away from being unavailable.
This is the gap Prepper Disk fills. It is an offline computer that broadcasts its own private WiFi network, letting up to 20 phones, laptops and tablets connect at once with no internet involved. The Premium version carries 512GB of content: the complete English Wikipedia with over six million searchable articles, offline medical manuals and FEMA disaster preparedness guides, more than 90,000 survival tutorials along with iFixit repair guides and Q&As, and detailed street, satellite and US National Park trail maps.
The practical appeal is that it uses devices you already own. Nobody needs to learn a new interface at the worst possible moment; you join a WiFi network and search. If you already own a Raspberry Pi, the brand also sells the premium software on a pre-loaded 512GB SanDisk Ultra SD card, which needs at least a Pi 3B, with a Pi 4 with 2GB recommended. We took a longer look at the device in our Prepper Disk review, and explained the day-to-day mechanics in how an offline survival computer works when the grid goes down.
Power it the same way you power a phone. Prepper Disk sells a 10,000mAh USB-C battery from Anker or INIU rated for about ten hours of runtime with the device, which is a sensible baseline if you are sourcing your own.
4. Storage: bags that protect the kit
The least exciting line on the checklist is also the one that decides whether the rest survives being stored in a garage. Water is the everyday threat. Prepper Disk's GoDark Faraday Dry Bag is a waterproof 10 litre bag made with two layers of RF shielding fabric, which means the kit stays dry in a flooded basement and shielded at the same time.
The signal-blocking side is optional depth rather than a must-have. If you want it, the Faraday Defense NX3 bag uses triple layers of metal-plated fabric containing nickel and copper shielding elements and blocks Bluetooth, WiFi, cell signals including 5G, GPS and RFID. There is also a bundle pairing the NX3 with a 10,000mAh USB-C battery pack. Treat this as the layer you add once the basics are in place, not the place you start.
5. The car, because outages do not wait until you are home
A second, smaller kit in the vehicle covers the half of your life spent away from the house. Powertac's Vehicle Emergency Kit ships in a rugged impact-resistant hard case designed to live in a truck bed, under a seat or in a toolbox, protecting the contents from dust, moisture and daily knocking about.
Whatever you assemble, the case matters as much as the contents. Loose gear in a trunk migrates, and gear you cannot find in ninety seconds may as well not exist.
The checklist
- One rechargeable flashlight per person, each with a spare battery.
- One adjustable-beam or headlamp option for hands-free work.
- A backup battery chemistry that stores well, such as CR123A cells.
- A high-output multi-port charger to refill everything during power windows.
- One universal multi-connector cable so any device can be charged by anyone.
- An offline information source that works without internet.
- A 10,000mAh or larger USB-C power bank, kept charged.
- A waterproof bag for the electronics, and a hard case for the vehicle kit.
- A tracker on the bag itself.
Maintenance: the step everyone skips
A kit is a subscription, not a purchase. Put a recurring reminder in your calendar twice a year: charge every battery and power bank to full, run each flashlight for a minute on high, check that cables still work, and confirm you can actually find the bag in the dark. Ten minutes, twice a year, is the difference between owning gear and being prepared.

And if you only add one thing this year, make it the information layer, since it is the piece nothing else in the house replaces — have a look at Prepper Disk and see what 512GB of offline reference actually covers.
