Frequently Asked Questions

Here are the answers to the frequently asked questions about solar batteries.

Do I Need a Solar Battery?

Not all people may appreciate the need for a solar battery, but if you’re someone who quickly burns power for your personal gadgets and devices due to consistent use, you would surely appreciate the need for solar batteries. Conventional power banks may give you the temporary power source to charge your mobile phones, but regular recharging of multiple devices will quickly drain power banks, leaving you with no more extra source of power to recharge. If you have a solar battery that recharges using the free energy from sunlight, you are guaranteed that you’ll have enough power to last for days and weeks, even when there are no power outlets around to recharge the power bank. So, this makes it a practical power source on the go during weeklong travels, camping, hiking, and other outdoor activities.

What Should I Consider When Shopping for Solar Battery Banks?

When shopping for a home solar battery bank, there are a few essential items in the specifications that you need to check to ensure you’ll get the best value for your money while giving you the best possible experience with the product. One of them is the rated capacity. The higher the capacity, the longer the charging hours you will get. This leads to another factor, which is deciding for your intended use. If you’re buying a power bank to recharge your smartphone once or twice daily, you’ll do good with a 10000mAh power bank. If you charge several times in a day for several devices, you may have to go for a higher-capacity solar battery bank. Another important factor is the charge cycle, which is the number of times you can charge devices with your battery bank until it goes dead. Some battery banks can recharge up to 500 times, while others can do more. Another notable feature is the type of output port, such as USB, Type-C, and micro USB. Make sure they’re compatible with your Android or iOs device. Other vital variables are a brand, price, waterproof and shockproof features, and more.

How Much Do Solar Batteries Cost in 2021? 

Standard solar battery banks shouldn’t cost you more than a hundred bucks these days in 2021. In fact, the most affordable with nice features you can get will only cost a little less than $30 on the market. However, batteries with higher rated capacities of 20000mAh will cost you more at around $50–70 bucks. If you, however, opt for much higher capacity ratings, the cost will go upward in hundreds of dollars. If you’re unsure how many milli-amp hours you need, you can use a solar battery bank calculator to compute the right capacity suitable for your everyday power needs.
