How To Choose The Best Solar Cell Phone Charger?

A solar charger is a useful accessory for outdoor activities: hiking, sailing, camping, motorhome, climbing, mountaineering, kayaking, boating in a pontoon boat, and more.

To charge devices using solar energy, you have several options:

  • Solar panels alone, whether rigid or semi-flexible
  • Solar panels with integrated battery
  • Solar panels with independent battery

Here are some essential criteria before choosing a solar phone charger:


The larger the solar panel, the more light it collects and the faster the energy will be stored in a battery. A small panel is easier to carry, but it will take longer to charge a battery.

A large area of solar panels is also ideal when the weather is cloudy or when the light is low during winter. Depending on the surface of the panels and the lighting conditions, charging times can vary from 4 to 16 hours of sunshine for the same battery.

Output Capacity

It is expressed in watts (W) and clearly indicated for each charger. The higher the number, the more electricity the solar charger can generate over a period of time.

The output power is important but it is also necessary to learn about the amperage of the USB outputs. An amperage of 2.4A each is required to charge a tablet.

Ability To Charge Multiple Devices

Some models of solar chargers can charge two or three devices at a time with good sunlight. Here again, the most powerful models in W are more efficient for recharging several devices simultaneously.

Always in optimal sunshine conditions, some solar chargers can power up to three devices. On the other hand, with less direct sunlight, recharging two or three devices simultaneously will take much longer than recharging just one.


A portable solar panel is used outdoors and must withstand the sun of course but also the wind or even the rain. On a solar charger, the solar panel part is resistant to the elements whether it is the sun or the rain. On the fabric parts, the colors may be washed out after several months of exposure.

In very hot conditions, the panel can warp. Models with external storage pockets are practical. These small pockets keep cables and other gadgets safe. They also keep the USB port dry and secure while charging.

Weight And Portability

It is an essential criterion for most outdoor activities such as hiking or climbing. On the other hand, lightness is not important for the boat or the motorhome. Some solar chargers are very compact and lightweight. They slip into a pocket easily.

Other foldable chargers are heavier and bulkier. A portable solar panel has stainless steel rings so it can be easily hung on a backpack, tree, kayak, bicycle, or tent.

Travel Time

For a weekend, an external battery may be sufficient. For several days off the grid, you will probably need a solar charger.

Either way, you can fully charge your devices and have the battery backup right before you go.

Mode Of Travel

For a solar panel to be effective, it requires long exposure to direct sunlight.

Some activities like cycle touring or sea kayaking are well suited to solar charging while on the move. For hiking, the solar panel attached to the backpack must be correctly oriented towards the sun. If you are hiking in the forest, a solar charger will be of little use.

How To Use A Solar Cell Phone Charger?

Using a solar cell phone charger is very easy. The first step is to ensure that the solar panels are relatively clean and dust-free. Otherwise, a damp cloth is ideal for cleaning them.

To obtain maximum power, you must then tilt the panels correctly. The angle of the panel to the ground should be about the same as your latitude. The panel should be a little less inclined in summer and a little more in winter.

If the panel is not pointed directly into the sun, it is likely to charge more slowly. Although it is possible to charge a smartphone by leaving the panels in the same place all day, it is recommended to reposition the panels every two hours for optimal performance.

Most solar chargers don't produce as much power as the manufacturers claim. The stated amperages of the output ports are really theoretical values. That is why it is advisable to charge only one device at a time to achieve a useful charging speed.

While charging, it is advisable to put your smartphone in the shade to avoid overheating. To avoid the heat, simply place the smartphone under the panel.

Final Verdict

Having a solar cell phone charger in your backpack while traveling can make a huge difference in how your trip goes. If you like to stay connected to the world even while camping, hiking, or other outdoor adventures, then you need to have a solar cell phone charger in your bag. If you have identified the right product from the consumer reports best solar cell phone charger reviews, then you can proceed to place an order to have an efficient charger on your upcoming trip.
