Best Solar Power Banks and Solar Chargers: Top 13 to Consider

May 1, 2024 09:43 AM ET

Dealing with a drained phone battery when hiking can be very frustrating. To avoid such problems, you need a solar power bank or charger when traveling or working off-grid. They are the most innovative must-have gadgets when stepping outdoors. 

Buy Solar Power Banks

The power banks and chargers are compact and can support more than one solar panel. Their features enhance electricity conversion capacity. They can power the latest devices as needed, making them great in an off-grid environment. When purchasing a power bank or solar charger, check their charging speed and bulkiness. Their compatibility and number of supported devices are equally crucial features to check. 

What is a portable solar charger?

A solar charger is a device that uses electromagnetic radiation from the sun to recharge electric appliances and batteries. Overall, the best solar chargers are designed to be portable. Their range of charging intensity is subject to the amount of sunlight. 

How do solar chargers work?

Portable solar chargers use the energy from the sun to produce electricity. Technically, electric energy is created through the movement of the free electrons. The electrons are usually fixed around an orbit. For the electric current to be produced, the electrons must be dislodged.

The energy from the sun, which comes in photons, has ample energy packets to set free the electrons. Solar charges do not charge the lithium-ion battery in your phone directly. On the other hand, they can charge an internal battery using solar modules. The charge is then distributed to an electric circuit. 

You can also plug the USB charger into the conventional source of power. The multiple recharging options make the unit very versatile. 

What is the lifespan of solar chargers?

The lifespan of solar powered chargers depends on several aspects of a solar charger. Solar panels can last between three to twenty-five years. The battery component also has a varying lifespan depending on the type. Generally, lithium iron lasts longer than lead acid, of course, depending on the maintenance. 

Solar chargers: pros & cons

Pros 

  • Solar chargers are the champions of clean energy. They emit no fumes and do not affect the environment
  • The solar-powered phone chargers require low maintenance cost
  • The chargers are safe to use and reliable
  • Solar chargers maintain battery capacity for longer by generating direct current (DC) from the sun. 
  • The chargers are autonomous and can be used anywhere

Cons

  • Even the top solar power banks are affected by changes in weather patterns and climate
  • Compared to the electric grid, solar chargers are relatively slow
  • Solar chargers have low power production that depends on their models required and the fitted solar panels. Some models take up sizable storage space, making the foldable ones very utile

What are solar power banks?

Solar powered power banks are detachable batteries fitted with solar panels. They are perfect for storing extra energy for electronic devices. The power banks can recharge and do not need to connect to an outlet for recharging. However, they can be plugged into an electrical receptacle to double up the electricity used. 

How do solar power banks work?

The solar panel power banks charge electronic devices using energy from the sun. The energy then powers a fitted rechargeable battery. Solar power banks should be charged first before being used. Apart from solar energy, the power banks can use a normal electric outlet.

When charging a device using power banks, connect it with a USB or wireless connection.

Are solar power banks any good?

The best portable solar power banks are ideal for outdoor usage. They are good for charging electronic devices in places with no electric power outlets. The devices let you carry along electronic appliances in off-grid surroundings and charge them as required.

  • The power banks are hybrid and can be charged using energy from the sun and the power grid
  • Solar power banks have adequate power capacity to power devices of dissimilar power ranges
  • They are easily charged with a strong power storage capacity

Cons 

  • Power banks are not recommended for regular use on your phones. There is proven evidence that they can damage phone batteries. The devices should only be in an emergency
  • Depending on the model, solar power banks can be quite bulky. Some are heavy and can take up much space in your bag

What is the difference between a solar charger and a solar power bank?

Both solar chargers and power banks are perfect for charging phones and devices. Solar chargers are power devices that turn solar energy into electricity. On the other hand, power banks are internal batteries for collecting electrical energy.
