You’re about to take the perfect nature pic with your cell phone. Right when you need it most, your phone dies. You’re nowhere near an outlet so how will you recharge? The best hiking solar chargers will help you power your electronics even when you’re out in the wild.

Taking a few extra pairs of AA batteries on your hike won’t do the trick. Today, most electronics rely on rechargeable lithium-ion batteries. You’ll need an external charger to keep your electronic devices running on your hike. Luckily, there are reliable, lightweight solar chargers that can recharge your devices.

One of our big goals here at The Adventure Junkies is to help you when it comes to gearing up for the outdoors. In this guide, we’ll walk you through what to consider when buying a hiking solar charger and show you our selection of the best models available.

HOW TO CHOOSE THE BEST HIKING SOLAR CHARGERS

AMPERAGE, WATTAGE, AND VOLTAGE

Look at the packaging for solar chargers, and you’ll see a lot of language about amps, watts, and volts. To understand what you’re getting, you need to know what these words mean.

 

WATTAGE

Wattage (watts) is a measure of power. As Goal Zero explains it, a watt-hour measures the power flow that occurs over one hour. Wattage is the measure of the solar panel’s power output capacity.

 

AMPERAGE

Amperage (amps) measures electrical current. The amp-hour is the amount of time a battery can supply that current.

 

VOLTAGE

Voltage (volts) is defined by About.com as the “electric potential energy per unit charge.” If you aren’t science minded that definition probably sounds abstract. Essentially, it’s the charge stored in a battery.

What does this mean? You want to know if your solar charger can supply the power you need. To get there, you can use a simple equation: watt – hours = amp – hours x volts

If there are devices you want to keep charged, find out their amp-hour and volt information. Plug those numbers into the formula. The answer will help you find what kind of wattage you need your solar charger to supply.

 

EXTERNAL BATTERY

Some solar panels include an external or internal battery. A traditional solar panel only works when the sun is out. Daylight may not be the best time for you to repower your electronics. This additional battery charges from the solar panels during the day. This lets you harness the energy from your solar panels at night.

For external batteries, there’s one more confusing abbreviation you need to learn: mAh. A mAh is a milliamp-hour, which measures battery capacity. This is the current that’s discharged by your charger over the course of an hour.

According to Ubergizmo, the bigger the number, the more energy your unit can store. If you’re going to use charger paired with an external or internal battery, select one with a large mAh number.

 

CHARGING EFFICIENCY

Some solar panels can take 18 hours or more to power an external charger or electronic device. That amount of time exceeds daylight hours in most places. If you need to recharge your electronics a lot, choose a solar panel that can charge faster.

You should also consider the weather in your region when you select a solar charger. Most solar panels struggle to charge in cloudy weather. However, some fare worse than others. If you’re hiking in the rainy season, solar panel efficiency can make all the difference.

 

OUTPUT CONNECTIONS

How many devices will you be charging? What kind of cords will you need to plug into your charger?

Most solar chargers have at least one USB port to connect your electronics. Some even have multiple connection points to charge several devices at once. Before you choose your solar charge, think about what you’ll need to charge while on the trail.

 

SIZE AND WEIGHT

Anytime you’re hiking or backpacking, size and weight is an important factor. The larger your solar panels, the more efficient they will be at charging. However, they’ll also take up more space in your backpack. Some solar chargers fold and take up very little space. Others are larger and bulkier.

You’ll also need to consider the weight of your solar charger. There are some devices that are less than a pound. Others are between one to two pounds. You’ll have to choose whether the benefits of the larger devices are worth the tradeoff of extra weight.
