Criteria for Choosing the Best Solar Chargers
You want to invest in a unit that’s both powerful and highly efficient at charging, which inevitably brings us to wattage. The higher the wattage the more powerful the portable solar charger. The vast majority of these devices have an efficiency range of between 20 and 27 percent, which is the solar energy conversion rate of the solar panels.
A higher percentage obviously means greater efficiency. For the best outdoor experience, you want nothing short of a model that is both efficient and powerful, and the best way of ascertaining these is by checking the chart that comes with the product, consulting a professional or better yet, calling the company. Also, make sure to check whether or not the charger is compatible with your devices.
The second most important consideration is the extent to which the model you’re enamoured of is portable. Under portability, you’ll need to consider how lightweight and compact the model is and the available carrying options. An ideal choice should not weigh you down as you walk around and should install easily on the back of a backpack so you can recharge your device while on the move. And for that to be a possibility, the device has to come with eye-holes or carabiners.
The outdoor environment is a harsh one, which makes all the more important that your portable solar charger is equally rugged and durable. The device should be able to withstand great impact and scratches occasioned by an accidental drop. It should additionally be water or rainproof so that when the heaven abruptly open without warning, the device is not damaged in any way. Being an electronic device, the likelihood of overloading or fluctuations in wattage and voltage can easily spell doom to the internal electrical circuit. The portable solar charger should incorporate a way of protecting itself from these likely possibilities.
Frequently Asked Questions
Q: Can I connect my electronic device directly to a portable solar charger?
A: That will depend on the design of solar charger you’re using and whether it has any safety features to prevent over-loading and over-charging. Modern models come with intelligent technologies such as a smart IC chip for automatically adjusting the current and voltage to deliver optimal power. The feature allows for a direct connection. Check with the company before trying this, though.
Q: How effective are solar panels on cloudy days?
A: For solar panels to work, even slightly, they need to be exposed to solar power. So when clouds get in the way of that, they essentially stop being effective. There’s no way of circumventing this, though.
As this buying guide makes so absolutely clear, there isn’t a solar charger that’s the absolute best. And while picking out one from a market full to the brim with various models, types and sizes can be intimidating, ensure you match your choice to your unique off-grid power needs. As a rule of thumb, cheap models lack the durability, power, efficiency, and ease of use that comes with buying a high-end model. So, don’t hold back; go all the way.
