Need even more power while you hike? Check out our guide to the best solar backpacks.First of three custom Hyundai Tucsons for SEMA. You’ll have to choose whether the benefits of the larger devices are worth the tradeoff of extra weight. There are some devices that are less than a pound. You’ll also need to consider the weight of your solar charger. Some solar chargers fold and take up very little space. However, they’ll also take up more space in your backpack. The larger your solar panels, the more efficient they will be at charging. Before you choose your solar charge, think about what you’ll need to charge while on the trail.Īnytime you’re hiking or backpacking, size and weight is an important factor. Some even have multiple connection points to charge several devices at once. Most solar chargers have at least one USB port to connect your electronics. How many devices will you be charging? What kind of cords will you need to plug into your charger? If you’re hiking in the rainy season, solar panel efficiency can make all the difference. Most solar panels struggle to charge in cloudy weather. You should also consider the weather in your region when you select a solar charger. If you need to recharge your electronics a lot, choose a solar panel that can charge faster. That amount of time exceeds daylight hours in most places. Some solar panels can take 18 hours or more to power an external charger or electronic device. If you’re going to use charger paired with an external or internal battery, select one with a large mAh number. This is the current that’s discharged by your charger over the course of an hour.Īccording to Ubergizmo, the bigger the number, the more energy your unit can store. A mAh is a milliamp-hour, which measures battery capacity. This lets you harness the energy from your solar panels at night.įor external batteries, there’s one more confusing abbreviation you need to learn: mAh. This additional battery charges from the solar panels during the day. Daylight may not be the best time for you to repower your electronics. A traditional solar panel only works when the sun is out. Some solar panels include an external or internal battery. The answer will help you find what kind of wattage you need your solar charger to supply. If there are devices you want to keep charged, find out their amp-hour and volt information. To get there, you can use a simple equation: watt – hours = amp – hours x volts What does this mean? You want to know if your solar charger can supply the power you need. Essentially, it’s the charge stored in a battery. Voltage (volts) is defined by as the “electric potential energy per unit charge.” If you aren’t science minded that definition probably sounds abstract. The amp-hour is the amount of time a battery can supply that current. Wattage is the measure of the solar panel’s power output capacity.Īmperage (amps) measures electrical current. As Goal Zero explains it, a watt-hour measures the power flow that occurs over one hour. To understand what you’re getting, you need to know what these words mean. Look at the packaging for solar chargers, and you’ll see a lot of language about amps, watts, and volts. HOW TO CHOOSE THE BEST HIKING SOLAR CHARGERS AMPERAGE, WATTAGE, AND VOLTAGE
