How to Choose a Portable Solar Charger

Keep the lights on using the power of the sun

The need for a power source to recharge electronic gadgets and use amenities such as LED camping lights in remote locations continues to grow, increasing the demand for portable power sources. Of the various off-grid power options, portable solar chargers stand out as the preferred solution. If you're new to this technology, you have probably asked yourself: Are solar chargers worth it? And the answer is yes because these chargers offer convenience and are environmentally friendly.

The key thing to remember when using solar chargers is how to maximize their potential. You need to align the solar panels correctly to gather the maximum amount of energy. Due to the high availability of solar energy, these chargers are a suitable option for long trips that require multiple recharges. If you're planning for the next outdoor adventure or camping trip, this guide answers the question, "What is the best portable solar charger?"

Types of solar chargers

Portable solar chargers come in a vast pool of designs to match your unique requirements. The three major categories are panel-only chargers, panels with integrated battery chargers and panels with detached battery chargers.

1. Panel-only chargers

This is the simplest form of solar charger. It often comprises a single panel or set of easily collapsible panels and a power outlet. Since they lack power storage, these chargers deliver energy directly to your devices or power banks.

2. Panels with integrated battery chargers

These all-in-one devices come with a solar panel and battery or battery pack as a single unit. They generate power and store it for later recharging use. Their convenient construction allows you to power your devices even when the sun isn't out. Panels with integrated battery chargers are also easy to handle.

3. Panels with detached battery chargers

Some solar chargers have independent solar panels and batteries. This simplifies storage during transportation to support use in a broad range of applications. These chargers offer the flexibility to leave the solar panel at home or at a campsite and only carry the battery.

Gadgets to power using the solar charger

Before opting for a specific portable solar charger, write a list of all the gadgets and electronics you need to power while outdoors. Do you have multiple devices that need charging? Then go for models with a high number of charging ports. Most solar chargers can charge smartphone and tablet batteries while powering LED lights and portable fans. If you're looking for the best portable solar charger for laptops, portable refrigerators and cookers, then look for solar generators and power banks with advanced power supply systems.

Length of use or trip duration

The next consideration while purchasing portable solar panels and batteries is the duration that you will need off-grid power. Based on the length of use, you can easily tabulate your average daily usage to ascertain the total amount of amps you require. When buying a portable solar charger, ensure you pick a model with high-capacity solar batteries. Aiming for batteries with a higher rating than your average daily need will make sure you do not run out of juice. Avoid draining batteries completely to prolong their lifespan.

Climate and weather

Whether you're planning a trip to a canopy-covered forest or the sunny beach, note that weather has a direct impact on charging time. Solar panels require adequate exposure to sunlight for peak charging. Place panels at strategic locations with ample sunlight to adequately utilize this source of renewable energy. Before selecting a particular charger model, check its energy conversion rating for optimal efficiency.

Charging speed

A key consideration when buying solar-powered chargers is the charging speed. How fast batteries recharge depends on power output, measured in volts. Sunlight availability also affects charging speeds, with more sunlight resulting in shorter charge cycles. Most solar power kits come as trickle chargers that provide just enough power to maintain portable devices at full power. Look out for chargers with high wattage ratings for shorter charge cycles.

Size and weight

Solar chargers often come in lightweight designs for easy portability. Their compact and streamlined construction makes them easy to handle and simplify storage. When buying portable chargers and power packs, the solar panels should have a large surface area for energy capture. Consider models with built-in attachment points or hooks to create a neat charging station.

Durability

Portable solar chargers are durable to support use during outdoor recreation. Some shockproof models can withstand heavy impact, such as falls and bumps, for increased durability. These charging devices often have tough casings and some flex points to protect the equipment from mechanical damage. Made of ultraviolet (UV)-resistant components, most outdoor solar chargers have rugged contact wiring to enhance longevity. Be sure to check the waterproof and ingress protection (IP) rating of the specific charger model before opting for one. Since rechargeable batteries have varying recharge cycle ratings, opt for models with higher ratings for enhanced performance.

Now that you've learned how to use solar chargers and what to look for when buying one, you’re more prepared to choose the best one for you to enjoy being connected on your next outdoor excursion.
