Have you ever been on a hike or in the middle of an unexpected situation when your flashlight runs out of batteries? It can really put you on a back foot! Not to mention, it's not always easy to find new batteries when you need them.

Rechargeable flashlights are a practical alternative to traditional flashlights. For instance, because you don’t have to lug around extra flashlight batteries, you save space in your gear or pack that you can use for something useful, like snacks to replenish your energy in the field.

The Fenix guide to rechargeable flashlights teaches you everything you need to know before (or even after) you get one for yourself. We'll take an in-depth look at different rechargeable flashlights, tips for choosing a light, and some of the best extra features on Fenix rechargeable flashlights.

So whether you're looking for a new flashlight for everyday use or an emergency kit, Fenix has all the info you need!

What Is a Rechargeable Flashlight?

Rechargeable flashlights have a built-in USB port, similar to a laptop, digital camera, or smartphone. You charge the battery inside the flashlight by plugging a charging cable into the device’s port.

A flashlight that uses rechargeable batteries isn’t necessarily a rechargeable flashlight. For example, many LED flashlights use rechargeable batteries, but if those lights don’t have built-in USB ports, they aren’t rechargeable flashlights. Instead, they’re flashlights that operate with a rechargeable battery.

What Are the Types of Rechargeable Flashlights?

Some rechargeable flashlights, such as the Fenix E-CP, use a USB charging cable to charge the built-in battery. These flashlights may have a useful indicator showing how much power remains in the battery, so you know when to charge it before commuting, camping, or backpacking.

Other rechargeable flashlights have removable batteries and USB charging ports. With these, you power the light with either a single rechargeable battery or two non-rechargeable batteries. Newer USB Type-C ports on the flashlight allow for fast, convenient charging.

How Do You Select A Rechargeable Flashlight?

One of the most important factors to take into consideration when selecting a rechargeable flashlight is the type of activity you intend to use it for. Some features of rechargeable flashlights that you may want to pay attention to include multiple lighting modes, rapid charging times, extended runtime, and high-lumen output. Let’s examine each element.

Multiple Lighting Modes

Do you need a flashlight for various lighting conditions and environments? If so, rechargeable flashlights with multiple lighting modes overcome any lighting challenge you encounter. With the press of a button, you can cycle through different light modes until you have the perfect light level for up-close tasks, seeing across great distances, and everything in between.

Rapid Charging Times

For situations when you have limited time, such as a last-minute evening walk or work emergency, rechargeable flashlights with rapid charging times help keep you on schedule. With a quick charge, you can power up the light and be on your way with a reliable light source.

Extended Runtime

When activities or tasks go longer than expected, rechargeable flashlights with extended runtimes last longer than traditional lights. How many hours a flashlight lasts on a single charge may depend on the setting. For the longest runtime, keep the light on its lowest setting.

Lumen Count

When powered by lithium-ion batteries, rechargeable LED flashlights emit more lumens. With a higher lumen count, you see more of your environment clearly and meet more extreme lighting challenges.


The nature of rechargeable flashlights makes them ideal for convenient on-the-go lighting. Most Fenix rechargeable flashlights have a compact design, so you can easily slide them into a purse, pocket, pack, or work vest without taking up precious space with extra batteries.

What Are the Best Extra Features of Rechargeable Flashlights From Fenix?

While exploring Fenix’s extensive selection of rechargeable flashlights, consider extra features that help you do and see more with the lighting tool. Some of our lights' most notable extra features include a power bank, penlight, and hands-free lighting. We’ll examine these features and give examples of Fenix lights that share them.

Power Bank

Some Fenix rechargeable flashlights, such as the Fenix E-CP, have a power bank that charges electronic devices like phones and smartwatches. So if you’re on the go and away from an outlet during an unexpected situation, plug your device into this flashlight’s port for a charge.


While it’s always great to have a pen on you, it’s even better to have a Fenix penlight. The Fenix T6 penlight is an EDC rechargeable flashlight and sleek writing instrument with a hidden Type-C charging port. The built-in flashlight emits 80 lumens of light, and the Schmidt ink cartridge provides a smooth writing experience that makes it easy to see why Fenix fans use the T6 as their go-to pen and light source.

Hands-Free Lighting

When you need both hands free to tie running shoes in the dark, perform maintenance tasks, or cook a late-night campsite meal, hands-free lighting becomes a must-have rechargeable flashlight feature. The Fenix WT16R is an all-purpose flashlight with a fast and convenient Type-C charging port. The magnets on the tail and back attach to most metal surfaces, but even without a metallic surface available, you can use the light and both hands with the durable clip that attaches the light to a pack, belt, or pocket.
