Points To Consider While Choosing Solar Chargers

Solar charges come in a range of sizes, types, and prices and are highly efficient camping companions. Simple things such as the material and efficiently of the solar panels can have a great impact on the results and the benefits of the solar powered chargers. The place of use of the solar charger, the terrain, and the charging needs will also influence the purchase decision of the buyer. The following are some of the key factors that will help the user in choosing the best solar charger for them.

  • The devices that will be required to get charged
  • Where and how to charge the devices
  • Need for an internal battery with the charger
  • Integrated battery
  • Type of solar panel used in solar charger
  • The efficiency of the panel
  • Watts and Amperage
  • USB connectors
  • Ease of use
  • Size and weight of the solar charger


The devices that will be required to get charged:

The devices that one brings along depends on the type of solar charger they would require. For small phones or GPS, a charger with a low specification is sufficient. But for charging power-hungry electronics, a charger of a higher specification is desired. While choosing the charger pay attention to the connectors as well as most of the charges will offer a USB port that works well for most modern electronics, but few devices might demand an adapter.


Where and how to charge the devices:

Solar charges can best attach with the backpack, motorbike or even the bicycle so as to collect some sunshine while on the move. They should not weight heavily nor slow down the user. It is important to compare the pack size and consider the surface area over which the solar panels can spread for charging.

For those looking for charging devices within their camp, a larger solar charger is the best. But for those who are charging on the go, compact ones are ideal. A more rugged model is required for those who use the charger during ice climbing or during water rafting.


Need for an internal battery with the charger:

Some solar chargers come with an internal battery giving the user the options to charge their device from that. Such a set up gives excellent ease of use and is also ideal in situations when the device is of need during sunshine hours. It is possible to power up the battery during the day and charges the electronics devices during the night.


Integrated battery:

Some of the solar chargers feature an integrated battery rendering more charging options. A solar charger without a battery can get paired with an additional power bank. But the downside of such batteries is their bulk and weight but it can free up the device during the sunshine hours when there is an option for charging the battery instead.


Type of solar panel used in solar charger:

There are three different types of solar panels that are used in solar chargers. The CIGS panels are more flexible as they are of a thin film of copper, gallium, indium, and selenide. They are also lightweight and are cheap to manufacture. There are chances that they degrade quickly and have a low rate of efficiently.

The other two forms of solar panels are poly-crystalline and mono-crystalline panels. The former makes use of multiple crystal ingots whereas the latter is of a single crystal ingot. Mono-crystalline panels have less energy loss and better efficiency.


The efficiency of the panel:

The percentage of panel efficiency specified the effectiveness of the solar panels to convert sunlight into electricity. Higher the efficiency value, better is the results. At present solar chargers with mono-crystalline panels have an efficiency rate of up to 25% whereas poly-crystalline panels have an efficiency rate of below 20%.


Watts and Amperage:

Before packing the solar chargers for charging gadgets on the campsite, it is important to learn the technical terms that are associated with them. Amperage and wattage are two important values that one needs to pay attention to when looking at the performance of the solar chargers. An electric current or the flow rate of the solar charger is measured in terms of watts. Solar panels that are 3W and 5Watts are sufficient to charge small devices and also older smartphones and even their batteries.

With a 5W panel, it could be possible to charge the device for 3 to 6 hours. Charging two devices simultaneously is only possible with chargers that are 10W and beyond. Amperage is the efficiency of the charger to charge the device. Dual port chargers have different manufacturer specifications. Chargers that can offer 2A or 2.5A at their individual ports are ideal for camping.


USB connectors:

USB ports are the ultimate functional units of the solar chargers as they help in charging a smartphone and other similar devices. Backpackers should learn thoroughly which if their devices would require an adaptor and which can get charged from the battery that packs with the solar charger.


Ease of use:

Solar charges are pretty simple to set up and use. The camper should only have to hook up their device, expose the charger to the sun and harness free power. Panels are easy to clean by simply wiping them off the dust and moisture with a cloth.

Most of the solar chargers of modern days hold a smart charging technology and its microchip will adjust to the charging automatically to the connected device for both efficiency and safety. The chip can also restart the charging after an interruption. For easy charging, the panel needs to be facing the sun at an appropriate angle.


Size and weight of the solar charger:

Ideally, the solar power charger should be small and light but for more power and to charge more device, panels of the bigger surface area is mandatory. Foldable chargers with efficient panels also come handy to charge more electronic gadgets. Panels with integrated battery add to the weight significantly but a battery pack with small and compact panels render less powerful charging.


Final Thoughts:

Solar panels help in charging devices and are ideal to keep in touch with friends and family back home. They also help with GPS navigation during the backpacking trips. There are a number of different solar chargers available with different specifications, making it an intimidating task to pick up the right one.

Therefore, it is important only to bring essential devices for backpacking trips. Backpackers should also match the capacity of their solar chargers with the devices they bring along with them. Solar chargers with lesser watts are cheaper and are less powerful. An expensive model may not be always appealing; careful consideration is required while choosing the solar charger. And we hope our guide will help you in making a wise choice.
