Want more deals? Visit CNN Underscored’s Guide to Black Friday for comprehensive coverage of the best sales and discounts during the year’s biggest shopping event.

Extreme weather like hurricanes, wildfires and earthquakes are an inevitability. Depending on where you live, you might experience several of these a year (or during a particularly stormy month), so it’s vital to stay prepared by having certain supplies on hand. Though some of these don’t often come cheap, Black Friday is an excellent time to stock up on what you need. And with the sales event ending soon, you’ll want to act quickly to take advantage of these deals.

This includes emergency essentials like flashlights and walkie-talkies as well as things like emergency radios, first aid kits, portable water filters and prepacked go bags. There’s really no such thing as being too prepared, though it is smart not to go overboard. Prepping takes planning and organization, and that starts with making sure you’re outfitted with the supplies necessary to manage whatever emergency comes your way.

Below are some of the best Black Friday emergency prep deals I’ve seen thus far. Do know that this list isn’t comprehensive, so buying everything here won’t necessarily set you up to be fully prepared. It’s intended to serve as a starting point and an opportunity to round out your survival kit or fill in any gaps you might have. Check back often, too, as we’ll be adding new deals throughout the holiday weekend.

Best emergency prep Black Friday deals

These Rocky Talkie Mountain Radios, aka walkie-talkies, are one of our favorites. They have a maximum range of 35 miles, boast up to four days of battery life and come with a carabiner clip to easily attach to a backpack or go bag. This two-pack is on sale for $22 off its normal price during Black Friday.

An emergency radio is a vital part of anyone's kit, and this model from FosPower is a standout. It's able to be charged via solar power or its built-in hand crank, and it's powerful enough to keep small devices like a smartphone charged. It's even capable of accessing emergency weather broadcasts.

This flashlight from ThruNite is compact and lightweight enough to stash anywhere, be it a go bag, a small backpack or even your pants pocket. You can get one for $18 off its normal price during Black Friday.

A flashlight is important for any emergency kit, but a headlamp might be even more practical with how they free up your hands. This two-pack from GearLight is great for stocking up. Clip the on-page coupon to get the full discount.

I don't need to tell you how important a first aid kit is. What I can say is that this well-stocked kit from Amorning comes with a lot. There's a total of 276 pieces including bandages, gauze, first aid ointment, scissors, safety pins, tweezers — you name it.

Sticking a big pack of batteries in your emergency kit is a great idea considering other items like flashlights, headlamps or emergency radios likely run on them, and you don't want to be caught with any dead devices. This massive pack is on sale for $14 off its normal price during Black Friday.

This battery pack from Anker is one of our team's go-tos. It's able to magnetically stick to the back of a smartphone, as it charges via MagSafe, and it recharges phones fast. If you stash one of these in your emergency kit, just make sure it's fully charged.

Access to clean, potable water is a necessity in an emergency, and this water jug from Upwoigh is a great way to ensure that access. It's on sale for $9 off its normal price, which may not seem like much, but we don't often see these discounted.

Ah, yes, the LifeStraw. It's likely you have one of these by now, as they're often on sale for every Black Friday, Cyber Monday or Prime Day sale there is. But there's a good reason it's here yet again: because it's great. This filter can help you stay hydrated in a pinch, allowing you to drink out of a river, lake or other questionable water source by removing parasites and bacteria.

The Sidekick from Leatherman is one of our favorite multitools and is something everyone should have in their emergency kit or go bag. It features 14 total tools, including pliers, screwdrivers, knives and a mini saw.

If you don't want to go through the trouble of packing your own go bag, this prepacked bag from Uncharted Supply Co. is your next best option. It has literally everything you'd need, including first aid supplies, protective eyewear and gloves, an emergency blanket and so much more. It's on sale for $150 off its normal price during Black Friday.

This prepacked go bag from Emergency Zone does a lot of the prep legwork for you. There's purified water, two sleeping bags, first aid supplies and toothbrushes. You could buy all these things separately, but there's no way it'd cost less than what it's on sale for during Black Friday.

One of our writers is testing emergency kits for the car right now, including one from Redi, the brand behind this 176-piece pack. It comes fully organized and is 36% off now at Backcountry.

A durable pair of work gloves is an underrated part of anyone's emergency kit. This is especially true for folks in areas where hurricanes or wildfires hit, and there's the potential to encounter various debris. This pair from Handylandy is on sale for just $10 during Black Friday.

Every emergency kit should have some sort of respirator mask in it, and there's none better than an N95. This three-pack from 3M is on sale for nearly half off its normal price, which brings each mask to $2.50 each.

Alright, so this deal is a whopping $1 off but since you should always have hand sanitizer stocked in your emergency supplies, whenever you can save any money is a good thing. This six-pack from Germ-X is the way to go.

Even if you already have a fire extinguisher in your home, it's good practice to double-check the expiration date to ensure they're still in working condition. If not, this four-pack will get you outfitted in a second — and it's on sale for just $80 right now.

Why these Black Friday deals are worth shopping

Stocking up on emergency prep supplies is a necessity, so it’s a major benefit when you can do that and save money. Even if something is only $10 or $15 cheaper than normal, those discounts add up quickly, especially if you’re buying multiple of the same item.
