Have you ever been on a hike or in the middle of an unexpected situation when your flashlight runs out of batteries? Rechargeable flashlights are a practical alternative to traditional flashlights. 

Running out of power in an emergency can put you on the back foot, and it can also be challenging to find new batteries when you need them.

For instance, you don’t have to lug around extra flashlight batteries. In that case, you save space in your gear or pack, which you can use for practical things like snacks to replenish your energy in the field.

The Fenix guide to rechargeable lights teaches you everything you need to know before (or even after) purchasing one. 

We'll explore various flashlights in detail and offer valuable tips. Additionally, we'll examine some of the top extra features found on Fenix lights.

Whether you need a new flashlight for daily use or to include it in an emergency kit, Fenix provides all the essential information you need!

What Is a Rechargeable Flashlight?

These 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 equipped with rechargeable batteries doesn't automatically mean it's rechargeable. For instance, while rechargeable batteries power many LED flashlights, a flashlight is only considered rechargeable if they have built-in USB ports, or a battery that also has a built-in port. Otherwise you’d need an additional charger if your flashlight or battery doesn’t include these.

What Are the Types of Rechargeable Flashlights?

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

Other rechargeable lights have removable batteries with USB charging ports. Newer USB Type-C ports on the flashlight allow for faster charging.

How Do You Select A Rechargeable Flashlight?

One of the most important factors to consider when selecting a rechargeable lighting device is the type of activity you intend to use it for. 
Some features of rechargeable lights that you should pay attention to include multiple lighting modes and rapid charging times. Also, high-lumen output and extended run time should be considered.

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. 
With a button, you can cycle through different light modes. This feature gives you the perfect light level for up-close tasks, seeing across great distances and everything in between.

Rapid Charging Times

For situations with limited time, such as a last-minute evening walk or work emergency, rechargeable lights 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, the best 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 lights emit more lumens. With a higher lumen count, you can see more of your environment and meet more extreme lighting challenges.


The nature of rechargeable lights makes them ideal for convenient on-the-go lighting. Fenix’s compact design allows you to easily slide them into a purse, pocket, pack, or work vest without taking up precious space with extra batteries.

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 having a pen on you is always great, having a Fenix penlight is even better. The Fenix T6 penlight is a rechargeable EDC 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. This feature makes it easy to see why Fenix fans use the T6 as their go-to pen and light source.

Hands-Free Lighting

Suppose you need both hands free to tie running shoes in the dark, perform maintenance tasks, or cook a late-night campsite meal. In that case, hands-free lighting becomes a must-have rechargeable light 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. Even without a metallic surface, you can use the rechargeable LED flashlight with both hands and a durable clip that attaches the light to a pack, belt, or pocket.
