Emergency Power Supplies & Off-Grid Energy Solutions

Our world has evolved over the last century to become reliant on energy. Energy has improved our standard of living globally and helped to extend the average lifespan of humans during that time. However, our reliance on energy can become a problem quickly during emergencies.

Whether you need to power medical devices, keep your food preserved, pump well water, or just have a light in the dark, energy will help you out. In this guide, we’ll cover essential power supplies and off-grid energy solutions to help you navigate emergencies.

This post on emergency power and energy shares strategies and supplies to keep your home, vehicles, and equipment visible and powered. When you buy through our links, we may earn a commission. Disclosure»

Emergency Power Supplies

The main equipment we cover under this category includes energy storage, power generation, and lighting. These can help your gear, vehicles, and home stay powered through disasters, emergencies, and survival situations.

Category Reviews

We’ve covered a lot of equipment over the years and revisit our reviews often to keep them current, which is important with the fast pace at which energy storage, power generation, and lighting have evolved over the past decade.

Storing Energy

The ability to store energy is easier than ever with the advancements in rechargeable battery technology. With LiFePO4 battery prices breaking below the barrier of affordability over the past decade, we’ve seen many preppers adding electrical energy storage to their preparedness plans, often accompanied by solar setups.

The days of liquid fuel are not behind us, however. Resource redundancy is important for preparedness, often described with the mantra “Two is One, One is None.”

Generating Power

Electronic communication relies on power sources to work. Even though most only need a little bit of power, you’ll need to plan on how you can supply that in an emergency.

Small power banks typically work well with handheld transceivers and cell phones, but larger equipment and computers may need power stations to operate.

Full-scale solar and other renewable types of energy are best, but inverter-style portable generators can also get the job done as long as you have fuel.

Generating Light

Most people rely on their cell phone light as an everyday flashlight, but there is a myriad of gear that can help you light your way through an emergency. From glowsticks to headlamps, being able to light up even a small area can improve your survival functionality drastically.

Technically, fire can provide light (and energy) as well, but lighting is more versatile since you can use it in a more controlled manner. Sure, fire is used for candles and lanterns, but fire has earned its own post (Survival Fire Starters & Firecraft Skills) and is more generally associated with warmth when it comes to survival.

Protecting Energy Devices

Energy devices are useful for a wide assortment of disasters, but are also vulnerable to the elements and specific disasters. Keeping smaller devices in waterproof bags is a good idea for starters, and protecting them from external charges (like EMPs and CMEs) can help as well.

EMPs can overload powered circuits if they aren’t protected, and can ‘splash’ energy across circuits designed not to carry large currents. During the largest CME on record, the Carrington Event, radio stations were severely damaged and caught fire from the atmospheric wave.

Faraday Cages and Bags

Plug-and-play ‘fixes’ for EMPs are designed to limit current on powered circuits, but don’t prevent EMP overload on circuits that aren’t designed for current, similar to a surge protector.

Faraday pouches and bags use a conductive mesh material to be a flexible Faraday cage for your equipment and work well in your survival kits or even in your pocket. Slipping your power bank into a Faraday pouch protects it from atmospheric hazards. We’ve already reviewed the best Faraday bags for your equipment.

Organizing Power & Energy Supplies

Power, energy, and lighting make up a major category of prepping supplies and survival gear, so many preppers tag the equipment with high-visibility tape so it can be identified quickly, even in low-light conditions.

Using the Color of Prepping system, we’ve assigned Power, Energy, and Lighting to the color yellow. Yellow is highly visible and is often associated with electricity and light, so it fits pretty well. You can print off a color organization card and use colored tape, paracord, or zip ties to label your power/energy gear, containers, and/or equipment accordingly.

The Final Word

Power and energy supplies are modern essentials for any survival or emergency kit. They keep your most advanced gear powered and usable, and when you have the right strategy, this power can be renewed almost indefinitely.

Some of the gear requires you to be familiar with it, and most of the gear works best if you plan it out and make sure it all works cohesively for a robust emergency energy solution.
