Factors to Consider When Buying the Best Solar

Charger for Backpacking

Power Sources 

You can use many different sources of power to charge a power storage unit, or your electronic tools directly. The most common sources, from slowest to fastest include:

  • Hydrogen fuel cell
  • Kinetic motion
  • Solar panel
  • USB
  • 12V DC
  • AC power

To recharge a portable power pack when you are not close to wall outlets, a car, or a USB output, consider one that you can recharge through solar. 

Solar Energy

It’s the most common type of off-grid power source today. You should consider using a solar panel when you want supplement power, and if your electronics surpass the available power. 

Solar energy is the ideal choice for extended trips or days outdoors, such as when camping.

Tips on Choosing Solar Chargers 

There are many common solar panel options on the market today. They include:

  • Panels only, which are either semi-flexible or rigid
  • Panels that have integrated storage batteries
  • Panels that have separate storage batteries

The main variables to consider:

  • Surface area – the size of the solar panel is directly proportional to the amount of light it can collect. While a small panel is easy to install, it might take a longer time to charge correctly. A large surface area is ideal for conditions that have a large amount of cloud cover, or the low light intensity that occurs during winter. More so, it can also be suitable for use when logistical constraints compromise the amount of time the panel gets sun exposure. Usually, the charge time varies between 5 to 16 hours of sunlight for the same battery. 
  • Output capacity – checking the output capacity of your chosen charger is crucial. It determines the type and range of devices you can power conveniently. You should remember that all solar panels have ratings in watts. The higher the rating, the more electricity this unit can produce in a specific time duration.
  • Semi flexible or rigid solar panels – the semi-flexible solar panels are easy to fold and roll up for convenient transport. More so, they are also easy to open to provide sufficient surface area than most rigid panels. Even, you have to consider the attachment options that are available with a solar panel. These will make it easy to install on your bike, kayak, or even backpack.

Hydrogen Fuel Cells

The most notable invention in portable power devices is to produce power through a chemical hydrogen reaction. This may require the use of a particular hydrogen cartridge. The voltage it produces might be below, but it's always available, unlike the sun. 

Power Storage (Battery Pack)

A solar energy producer is best for use when you want to charge up a storage battery, instead of an electronic device. Why?

These power sources may not have any circuitry to control the flow of electricity into your device. Such an issue might lead to damage. Thus, ensure that you check the manufacturer's recommendations. Some solar panels come with a regulated USB output, which you can use for direct charging of small devices.  Its good to go for solar panels that have waterproof flaps, to help improve their longevity and functionality. The categories you are likely to come across include:

  • An integrated storage battery – this type provides all in one convenience of a power generator, and it makes power with a battery for storage.
  • An independent storage battery – this type provides the flexibility you need to leave the generator at your home or base camp. You may only take the battery in this case.

NB: If you want to buy a solar panel with a storage battery, pay attention to the specific battery specifications. This should be the most crucial aspect of your power supply package.

Critical Specs for Portable Battery Packs

Storage capacity – this indicates the amount of charge the pack can store for future use when charging your electronics. It’s a good indicator that you have a good quality charger in your hands. 

You can easily get an idea of the recharges you have available. You may have to compare the storage capacity of the battery to that of the battery in your appliance. Usually, this formula is rated in milliamp-hours (mAh) or Amp-hours (Ah). For instance, 2200 mAh = 2.2 Ah. Watt-hours (wh) is also another aspect of measuring battery capacity. To convert watt-hours to mAh: (Wh/Volts) x 1000 = mAh.

Useful tip – transferring energy from one battery to the other is not often an efficient procedure. For this reason, don’t expect a 2000mAh pack to charge a 1,000mAh battery twice.

To recharge or top off your appliance, you may require a battery pack with adequate storage capacity. More so, you also need a battery pack with sufficient output voltage, to get the energy to your device.

How much is adequate? Find out the storage capacity of the battery in your appliance. For electronics that inbuilt batteries, consider the technical specs to determine battery capacity. Plus, if your device uses replaceable AA batteries, and this is not an issue. Remember to go for a battery pack that has either of these features

Power Output

The output of the charger should be equal to the input battery voltage necessities of your chosen device. If it is any lower, this might cause a drain on the power in your device, rather than charging it up. 

Most portable battery packs are suitable for charging small appliances such as cell phones, mp3 players. That said, not many can charge large devices such as laptops. 

Furthermore, a small electronic device is possible to charge using a USB cable with a 5V output rating. The large devices require a DC power output. These include power ranges of between 12V – 24V. 

Battery technology

Portable battery packs don’t only vary in terms of output or capacity, but also size, weight, and technology. The common variations include: 

  • NiMH – (Nickel Metal Hydride) batteries, these are likely to be rechargeable AA or AAA batteries. A battery pack that has these is a convenient choice for your needs.These include devices such as GPS, headlamps, and cameras. Rather than recharging your device, you can just swap out the batteries.
  • Lithium-ion and lithium polymers – these are the most common portable battery packs in the market. They are similar to the inbuilt batteries you may find in electronics.
  • Lead-acid batteries – these batteries are large and heavy. They also have the most enormous power output and capacity.

Output Connectors and Adapter Tips

If you go for a solar with a battery, whether it’s integrated or independent, ensure it has the correct connectors for your convenience.

If you buy the panel and battery separately, check the output connect and check whether its suitable for charging your device. More so, also check if you can use it to connect a separate battery pack. The standard options to consider include a USB, a connector, or DC output with voltage control.


Being able to enjoy your time backpacking is all about preparing correctly. It's good to have a passion for the outdoors, and it's also another to be ready for the outdoors. Thus, this guide has identified the best solar charger for backpacking you should consider. When you have one of these chargers, you will find it easy to charge your devices each time. That said, before you invest in a charger, remember to consider critical factors of your chosen device and the charger as well. This way, you reduce any likelihood of causing damage to your device.
