What Is a Solar Charger
A solar charger is a portable electric gadget that has multiple solar panels forming a solar array and a charge controller. Small solar panels are installed at its top that converts photon‘s energy into a dc power supply that goes through a charge controller, usually with multiple outputs, which can be used to charge your cell phones, power bank or any other electronic gadget.
Solar charger produces 5/18v dc at different amperes that are supplied to the electronic gadgets for charging through a built-in charge controller.
Modern chargers can have multiple output voltage and amperes, suitable to supply different kinds of electronic appliances. These are perfectly designed for charging lithium-ion batteries and lithium-polymer batteries, which are mostly used in our electronic gadgets. Although, it can even charge lead-acid batteries too.

How To Select The Best Solar charger
There are multiple details to check out before buying a solar charger, but before going for an inspection of solar chargers in the market, make sure what you need and why you need them. If you know why you need a solar charger that would solve half of your problems.
- For which device you are looking for a solar charger? Some chargers fit with smartphones only and are cheap. Some chargers can charge any electronic smart gadget having multiple options and output supply and are expensive. So, get to know for which product you need a solar charger.
- Check the power output of the solar charger. It is necessary to read the power output of your solar charger before buying. High power output in watts such as 100W means you can charge multiple devices at once, and a charger close to 20-30watts would be good for charging multiple smartphones but a single tablet or iPad.
- Weather Resistant charger are strongly recommended. A quality solar charger is one that is weather resistant. As you are going to place it outdoors for solar energy absorption, it must be weather resistant. So, that it doesn’t get affected by dust, water, high and low temperatures.
Solar charger Maintenance
For any electronic product, there is not much to do in maintenance, especially when it is solar technology related. There are a few maintenance tips for your solar charger as follows.
- Stay Careful to its prescribed limits. All you have to do is be careful with its given limits. Don’t charge many devices at once, even when it has multiple ports. Always keep total power output in your mind, and don’t try to over drain it as that can damage both your solar charge and the device.
- Clean them before every use. Always keep it clean, don’t clean it with too much water, but strong and dry fabric. Always check that your device is connected well through ports, otherwise, it might heat up.
- Don’t challenge its weather resistance much. Even when it has weather-resistant fabric and surface, do not challenge it much as it will lessen its life in the process. As it won’t charge in the rain so keep it inside and clean it before and after every use.
Solar Charger Vs. Power Bank
Solar chargers may or may not come with attached battery but solar power banks have built in battery to hold charge. Having the battery attached is an advantage and drawback at the same time. Solar power bank’s capacity to deliver is limited to it’s built in battery size while solar chargers can charge any size of battery with the right connector.
|Feature||Solar Charger||Solar Power Bank|
|Power Output options||Multiple outputs||Single or few|
|Power input efficiency||High||Low|
|Power output quality||High amperes||Low amperes|
|Auto current adjustment||Yes||No|
|Compatibility||All electronic gadgets and devices||Smartphones only|
Choose the best solar charger based on your need and never push it through it’s limit. It’ll serve you good for years. My list here to help you get the most efficient chargers for long term use.
