The voltage of the Nomad 50 has been consistent between 5.03 volts and 5.07 volts in the different test conditions, which means its dependability.

Additional Features:

But the Nomad 50 is bigger though it is more versatile than any other panel we tried. It has eight milimeter chaining connector to add panels and adjustable legs for tilting them to the sun’s direction. Capable of working even through cloudy skies, this technology also makes it perfect for power generation in situations that are not so ideal.

The Goal Zero Nomad 50 is an extremely powerful unit and supposes the installation of durable systems which require large power output. Although less portable as compared to smaller models, it is still renowned for its stability, dependability and versatility; hence, it is the best option for charging large devices and for emergency usage.

Should You Go For A Portable Solar Charger?

With technology playing a big role in most of our lives, it is difficult to stay disconnected in several situations. No matter what type of outdoor activity you’re organizing – whether it’s a camping, hiking trip or you’re getting ready for possible emergency event – a portable solar charger may turn out to be a useful accessory.

Scenarios Where a Portable Solar Charger is Beneficial

 Extended Outages: When critical power sources like the grid are not available for a prolonged period of time, a mobile solar charger is a device that can be turned to for a continuous power supply.
 Off-the-Grid Adventures: For hikers and campers who encounter a situation in which they rely on electrical gadgets such as smartphones, GPS watches, flashlights, and headlamps, a solar charger must be included in their packing as a source of power supply for these gadgets.
Emergency Preparedness: The interruption of natural disasters, power failures or emergency may change usual power supply sources. A solar charger becomes a simulation tool for keeping the communication devices charged. It becomes also a decision-making machine for the users.

Limitations of Traditional Power Sources

Limited Capacity: Once the power bank is drained, it has to be topped up, hence making it impractical for a long term cut from the grid.
Environmental Impact: The disposal of batteries create environmental pollution, and the rechargeable batteries need a source of power supply.
Dependency on Power Grid: During the outages, you will be dependent on the grid, and therefore, there will be no power and, consequently, the alternative energy sources become a necessity.

How much power do you expect to have?

Getting the knowledge of the charging capacity of the portable solar chargers will help to chose the right one. We tested our multimeters, dummy loads, and real devices that utilized the USB slots, and they provided us with the charging potential results of every model.

The Efficiency of X-Dragon 20W Interest Rate

While conducting our tests, the X-Dragon 20W was extremely efficient managing to charge 3,087mAh in two hours through sunlight. However, the actual charging efficiency can change depending on weather conditions, brightness of the sun, and the panel’s direction.

Factors Influencing Charging Performance

1. Sunlight Intensity: More powerful sunlight induces every cell to charge faster and more completely. Nevertheless, certain chargers show good performance even in the shade.

2. Panel Orientation: Maximizing the solar panels‘ orientation property towards the sun increases charging efficiency. Because some models, for example the Goal Zero Nomad 50, have legs that can be adjusted, you can divegon the panels.

3. Weather Conditions: Fortunately, most solar chargers provide their optimal performance only when in direct sunlight. However, there are models like the X-Dragon 20W solar charger which are resilient even when under the occasional cover of the clouds.

Choosing the Right Solar Charger: Its Advantages and Disadvantages
Choosing the right portable solar charger requires taking into account the many factors with a view to ensuring it caters your specific requirements.

Key Considerations

  • Power Output: Find the wattage you need by evaluating how much power you need. The X Drago 20 watts smaller charger is best option for charging your normal device. While the Goal Zero Nomad 50 model is more suitable when you need ample power.
  • Portability: Take into account the portability factors such as size, weight, and foldability based on your intended use. Lighter models are better for trekking or backpacking, while heavier models are ideal for multi-day camping trips.
  • Durability: Determine the strength and durability of the solar charger by checking. An outdoor-grade design is built into the charger to make it more fit for outdoor experiences.
  • Versatility: If you want to have more productivity, pay attention to additional useful features, such as USB ports, LED indicators, and compartments for devices. Goal Zero Nomad 50 has a 8mm chaining connector for tying together to increase the power supply capacity.
  • Weather Resistance: While the majority of solar chargers are made for bright weather, you could find that some of those models perform much better in overcast conditions because they can consistently provide a power supply even when the sun is shining weakly.

Ups and Downs

While the X-Dragon 20W and Goal Zero Nomad 50 record the best results during our testings, the advantages and disadvantages of other products must be taken into account too.

1. BigBlue 3: Although the BigBlue 3 is characterized by its miniature size, it had power inconsistency and charging inefficiency that made its application for long use off the grid less reliable.

2. Goal Zero Nomad 5 Panel: The Nomad 5 Panel, which was rather performant, fell short on output power required for the high-end devices, hence the device had limited possibilities how it can be used.

3. BioLite SolarPanel Series: BioLite’s products demonstrated some degree of fairness but failed to maintain the specified standards on a regular basis thus they were not a viable option for long off grid journeys.

4. Anker PowerCore Solar 20000: Anker’s product delivered good power performance but could be picked to be less reliable under unstable conditions.

5. Hiluckey Solar Charger: Despite its lightweight and portability, Hiluckey Solar Charger , however, is less affordable and profitable as its output power and life expectancy are worse.
6. QiSa Solar Power Bank: Similar to QiSa’s model, our top choices gave acceptable performance but lacked the efficiency and consistency as materialized in the picks mentioned above, consequently making this suitable for basic charging needs only.
