How to Charge Electronics
When the Power is Out

Battery Pack

A battery pack, power bank, and portable charger are essentially the same thing, and the terms are often used interchangeably. They may also be called fuel banks or backup charging devices. While there are many options available on the market, they all serve the same primary purpose: storing electrical energy in a rechargeable battery that can be used later to charge other devices. These lightweight, USB-enabled portable chargers are convenient to carry anywhere, making them essential for powering devices when electricity isn’t available.

Portable Power Stations

A portable power station is like having a compact, rechargeable generator at your fingertips. These handy devices store energy in a built-in battery, giving you a versatile and eco-friendly way to keep your electronics and small appliances running during power outages or outdoor adventures. They often come with various output options, including AC outlets, USB ports, and even 12V DC ports, making them perfect for powering everything from phones and laptops to mini-fridges and lights.

Uninterruptible Power Supply

A UPS is basically a power strip, surge protector, and backup battery all rolled into one. When the power goes out, the battery kicks in to keep whatever's plugged into it running for a little while. This could be your computer, Wi-Fi router, or even small appliances like a fridge—depending on the UPS's capacity. Many models come with multiple outlets, so you can plug in several devices at once, and most also have one or two USB ports for charging phones or tablets. Once the battery is drained, it needs to be recharged to restore it backup functionality.

Solar Panels

A solar panel charger converts sunlight into electrical energy, which can be used immediately to charge devices directly or indirectly, using external batteries that, in turn, charge devices. For this process to work, the panel needs direct full sunlight - shade or cloud cover will reduce output. Portable solar panel chargers come in a wide range of watt capacities, from compact 10-watt models to larger setups of 100 watts or more.

Solar Chargers

Portable solar chargers are compact, lightweight devices used to generate electricity from sunlight and recharge small electronics. They typically consist of one or more small solar panels; some models also include a built-in battery, but many panel-only chargers do not. Their main purpose is to harvest solar energy and pass it to devices like phones, tablets, radios, flashlights, GPS units, or to recharge external power banks.

Solar Power Banks

A portable solar power bank is a lightweight rechargeable lithium-ion or lithium-polymer battery that stores electrical energy from the sun using built-in or detachable solar panels, or from traditional wall outlets, solar generators via USB, or vehicle power sources. They are then used to charge low- to medium-power devices, such as phones, tablets, lights, radios, and other USB-powered devices. Most models also support dual charging, allowing for both solar and wall charging, so you can top off the battery before an outage and maintain it with sunlight.

Solar Generators

A solar generator is a powerful solution for keeping your devices charged during power outages. With its built-in battery and solar panels, it stores energy from the sun to provide ready-to-access power when you need it. USB ports are a standard feature for charging phones, tablets, and other small electronics, as well as AC outlets for larger devices. Many solar generators even offer multiple USB ports, including USB-C, to support faster charging and multiple devices at once, making them a popular choice for emergency preparedness.

12V DC Outlets

Most modern vehicles come equipped with USB ports, making it easy to charge your phone directly. Just be sure to have the correct cable and, if needed, an adapter compatible with your phone model. For example, iPhones may require a specific charger or adapter. If you want to charge multiple devices at once, consider getting a dual USB adapter for added convenience.

Car Chargers with USB

Some car battery jump-starters come equipped with USB outlets, making them versatile tools. Not only can they jump-start your car’s battery, but they can also recharge cell phones, tablets, and power banks. Many models feature two USB ports optimized for rapid charging, letting you power multiple devices at once. When shopping for one, make sure the car charger is compatible with your phone and other devices. If it’s not, a simple adapter can solve the problem.

Inverters

A vehicle inverter can be a lifesaver when it comes to charging devices during a power outage. It works by converting your car's DC (direct current) power into AC (alternating current), which is the type of power used by most household devices. This means you can plug items like laptops, small appliances, or even your phone's wall charger directly into the inverter, just as you would with a regular power outlet at home.

Fuel Generators with USB

A fuel generator with a USB port is a versatile power solution for emergencies or off-grid situations. These generators not only provide traditional AC power for larger appliances but also feature USB ports for directly charging phones, tablets, and other small devices. This added convenience makes them a great all-in-one option for keeping your essentials powered.

Hank-Crank Chargers

Hand-crank chargers work just as they sound—they use your physical effort to generate electricity. By turning the crank, you create a magnetic field that is converted into power. This energy can either charge your phone directly or be stored in the charger’s internal battery for later use. However, charging is not fast, so patience is key. For most modern smartphones, a few minutes of cranking will provide enough power to send a quick text, while making a phone call could require 10 to 20 minutes of steady effort.

Camp Stoves with USB

This option may surprise you, but the Biolite Camp Stove is a favorite in the prepper community for good reason. Not only can it cook your meals, but it can also charge your phone, tablet, or other devices by generating electricity. This portable, wood-fired camp stove runs on nearly any flammable biomass - twigs, sticks, pinecones, etc. - making it easy to fuel in the great outdoors. Its USB port leverages the energy from the fire itself to charge devices, adding incredible value to its utility.
