In this article, we'll show you that USB connection is the only thing you need to charge a flashlight.  

USB Connection is the Only Thing You Need

In order to charge a flashlight with a USB connection only, your flashlight will need to have a couple things.

First, you flashlight will need to have rechargeable battery.  Second, your flashlight's battery will need to be compatible with a USB charging. 

Typically, these flashlights will included a USB cable, which is used to connect to devices such as laptops, phones, etc, for charging.  See our list below for examples of USB compatible flashlights.

How to Charge a Flashlight with a USB Connection

There are a few electronic devices that can be used to charge a flashlight with a USB connection.  

First, and the most common way to charge your flashlight with a USB connection is with a laptop or computer.

Computers have multiple USB type connections that can be used to charge your flashlight.  However, these will require your computer to be charged from another power source to be charged.      

Second, you can use a portable power source to charge your flashlight. An example would be a portable power bank or gas powered generator, but these require a power source to be charge.

What If You Don't Have Access To a Power Source to Charge Your Portable Power Sources?

This is where charging your flashlight with USB connection only really comes to life. 

Lets say that you're out in the wilderness hiking, camping, or hunting and you don't have any power sources to charge your portable power sources that you would typically use to charge your electronic devices.

The best solution to this problem is to switch to a solar charger, which gives you unlimited power provided by our sun.  

With continuous innovation and advancement in solar panels tech, solar charging has become a reliable and practical source of electrical power.

Power output provided by solar panels has improved a lot since the beginning days of solar tech and now it provide electricity at optimal outputs with portable minimalistic solar devices that won't burden you with extra weight or bulk. 

So, for those on the go outdoors with no access to electricity or those who are simply looking for a green way of charging your electronic devices, solar power is the way to go.  See examples below.

Although, solar charging has become a reliable source of electrical power, it does come a higher price.  

Typically, solar charging devices can in some case cost hundreds of dollars, but they will save you money overtime. 

Problems with Solar Charging

Here are several common problems with solar charging:

1. No sunlight no power.

2. Problems with internal battery. (Solar panels store power inside internal batteries which can be faulty and go bad overtime.)

3. Fragile equipment. (Solar panel are built with fragile solar tech, which can be easily damaged or weathered.)

4. Faulty internal hardware. (Solar panels are complex tech devices, which are susceptible to faulty hardware.)

5. Capacity Problems. (Capacity may be too low for your device.)

Tips for Using Solar Charging

• Buy the right solar charging panels.  The output matters when charging electronic devices.  The electrical output from your solar panels may not be enough to charge your device.
• Check compatibility.  Make sure that your device is compatible with solar charging device.
• Don't overcharge your solar panels.  This can damage the internal batteries.
• Don't overheat you solar panels. This can cause damage to internal hardware.
• Be careful when handling solar panels. Solar charging panels are fragile and can be damage easily easily beyond repair.  
• Learn about the solar power before use.  Learn about how it works so that you're not disappointed by your results.  

Final Thoughts

USB solar panels have become more efficient and practical when charging everyday electronic devices.  If you're on the go and don't have access to batteries or electricity, solar charging is the way to go!

All you need a sunlight and you have access to unlimited power to charge flashlights and other everyday electronic devices.
