How Do Solar Power Banks Work?

Solar power banks work by harnessing energy from sunlight and converting it into electricity that can be stored in an internal battery. The core components of a solar power bank include photovoltaic (PV) solar panels, a charge controller, and a battery. When exposed to sunlight, the PV panels absorb photons and generate a direct current (DC) electrical charge. The charge controller regulates this flow of electricity to ensure that the battery is not overcharged or damaged.

As the battery stores the converted energy, it becomes a portable power source that can be used to charge various devices like smartphones, tablets, or other USB-compatible gadgets. Solar power banks are an eco-friendly and convenient solution for staying connected and charged on the go, especially in outdoor or remote locations where traditional power sources may not be readily available.

Solar Power Banks – Advantages and Disadvantages

The Ideal Solar Power Bank – My Recommendation

Although they offer off-grid power, most solar power banks have small solar panels with slow charging times. If you need a power bank with consistent access to off-grid power, I recommend the Goal Zero Sherpa 100AC paired with either a Nomad 50 or Boulder 50 solar panel.

I own a Sherpa 100AC and use it nearly every day. I don’t use it for off-grid purposes often, but if I want/need to, it can charge from a 50W solar panel. I’ve done a lot of research on solar power banks, and this is the fastest-charging solar power bank combination that I know of.

However, this combined system has a hefty price tag. I only recommend this kit to people who either:

  1. Want backup power for charging small devices (phones, LED lights) in case of emergencies, or
  2. Need consistent off-grid recharging power and as much portability as possible
