Solar power banks refer to small and portable battery packs integrated to a solar panel, covered in a sturdy, compact cell. Some solar power banks have the ability to charge up to three devices simultaneously, which makes them perfect for that hiking, camping, or other outdoor activity.
Although solar power banks come packed with a battery and solar panel, their particulars differ significantly. Some of them provide the power that can charge a device once or twice, while other huge solar power banks can charge up to five or six times.
These gadgets come with some optional features, including wireless device charging, in-built flashlights, and USB output. Check out our review for the 10 best solar power banks in 2020 below.
How to Choose the Best Solar Power Bank
As mentioned above, solar power banks vary in many ways and the market has a pool of these products. With each claiming to provide the best, it can be confusing to choose between them. So, what do you look for when choosing the best solar power bank?
- Capacity & Size – The size of a battery determines its capacity. So, the bigger it is, the higher the capacity and vice versa. If you need a power bank enough to charge one or two devices, one that fits your pockets (5000mAh or less) sounds great! But anything more than that requires a bag.
- Charging Speed – How fast does the power bank charge your phone? Make sure you double-check the battery output’s voltage (V) and amperage (A) which when multiplied gives you the wattage (W).
Fast device charging requires three elements, including a device, battery, and cable (all with a charging circuit compatible with fast charging standards). Quick Charge (by Qualcomm) and USB Delivery are the two major quick charging standards available.
- Input & Output Ports – The type of port(s) determines both charging speed and device compatibility. Most battery packs include a standard USB port type A at a minimum for both input and output. But since most phones, laptops, and tablets require USB port type C, they will be included in addition to the standard USB-A.
Ensure you check as some power banks might have USB type C input but not output.
- Safety Features – Sometimes you will get sunlight interruptions or other faults that might cause damage to your devices. As such, check that your solar power bank comes with safety features such as overcharge and short circuit protection.
- Pass-through & Wireless Charging
These are extras that you should also consider before purchasing a backup battery. Pass-through allows for device charging and battery charging simultaneously. This is important, particularly when both gadgets are running out of charge.
Wireless charging is also common so you can charge your devices without using a USB charging cable. The dominant standard on the market is Qi and works well with iOS and Samsung smartphones, plus other few batteries.
