Best Solar Power Banks: Detailed Reviews
I have compiled a comprehensive list of the best solar power banks ideal for backpacking enthusiasts. Check out my top picks below to stay connected and powered up during your outdoor adventures.
Hiluckey Solar Charger 25000mAh
The Hiluckey Solar Charger 25000mAh is an excellent choice for backpacking with its high capacity and durable design.
I was impressed by the high capacity of this solar power bank, as it could charge my phone up to 8-10 times and my tablet 3-4 times on average per charge. This meant that during a 9-day backpacking trip, I never had to worry about my devices running out of power.
The four large solar panels on the Hiluckey Solar Charger allowed it to charge efficiently in direct sunlight, which is incredibly useful when backpacking in remote areas with no access to electricity.
However, I did find that it took two sunny days for the solar panels to fully charge the power bank.
The fast charging feature was also a pleasant surprise. With the upgraded 15W outputs, I could charge my iPhone to 50% in just 30 minutes. The charger supports one USB C port and dual USB A ports, enabling me to charge three devices simultaneously.
Although the rugged construction is both dust and splash resistant, I noticed that there was no built-in hook for attaching the solar charger to my backpack. I had to improvise and use a separate hook to hang it securely. in spite of that little drawback, this is still my top pick due to the fast charge feature!
SunJack 25W Foldable Waterproof Solar Panel + Power Banks
The SunJack 25W Solar Panel is an excellent choice for backpackers in need of a rugged, portable, and efficient power source for their devices.
I recently took the SunJack 25W Foldable Waterproof Solar Panel on a backpacking trip and were impressed by its durability and efficient power output. The weatherproof ETFE exterior layer ensures that the panel is rugged and able to withstand a variety of weather conditions, perfect for outdoor adventures.
The foldable design made it easy to fit into my backpack, and the magnetic closure system kept the panels neatly closed during storage.
The mesh pocket allowed for proper airflow to prevent my devices from overheating while charging, and the elastic straps kept my phone and power banks secure during transportation.
However, I noticed that the solar panel is heavier than I initially anticipated, which may be a concern for some backpackers. The power banks also seemed to supercharge some of my devices, which raised concerns about potential battery damage.
Lastly, one of the charging ports appeared to perform slightly better than the other. Despite these negatives, the overall efficiency and durability of the SunJack 25W Solar Panel make it a must-have for backpackers seeking a reliable power source on the trail.

Overall, the SunJack 15W foldable solar panel and power bank are a reliable and rugged option for backpackers looking for a portable off-grid power source for their outdoor adventures.
FlexSolar 40W Solar Charger
A reliable and efficient solar charger for backpacking adventures, with great features for both convenience and durability.
Having tested the FlexSolar 40W Solar Charger on my backpacking trip last fall, I was impressed with its performance and portability. The high energy conversion rate of 24% allowed me to charge my phone and power banks efficiently in sufficient sunlight.
The multiple charging outputs, including USB-A QC3.0, USB-C PD2.0, and DC 19V provided versatility in charging different devices at the same time, although I would not recommend using the DC and USB ports simultaneously.
One of my favorite features of this solar charger is its IP67 dustproof and waterproof protection, along with its ETFE laminations. This made it much more durable than other solar chargers I have used, withstanding various weather conditions and wear on my journey.
However, I did notice that the junction box is not waterproof, which is something to consider if you plan to use it in particularly wet conditions.
Despite the minor drawbacks, I found this solar charger to be an excellent addition to my backpacking kit and would recommend it to anyone looking for portable solar charging options.
Mregb Solar Power Bank
This solar power bank is perfect for backpackers searching for a reliable, durable, and versatile on-the-go charging solution.
I used the Mregb Solar Power Bank during one of my latest backpacking adventures. It was a real lifesaver when my devices needed a quick recharge after a long day of hiking. The large 42800mAh battery capacity allowed for multiple device charges, and the rugged, waterproof construction made it an ideal companion in harsh outdoor conditions.
The built-in LED flashlight proved to be an excellent feature, providing a bright light source during those unexpected nighttime outings. However, one thing to note is that the solar charging option is slow and should be viewed as an emergency backup solution rather than a primary charging method. To ensure optimal performance, charge the power bank using a power adapter with a 5V2A output or higher.
While I found the Mregb Solar Power Bank to be a valuable addition to my backpacking gear, it’s worth mentioning that it’s not compatible with USB Type-C devices.
If you have a smartphone with a battery capacity of 4500 – 5000mAh, expect around 4 – 5 full charges from this power bank. Despite these drawbacks, I still believe it’s an excellent pick for backpackers who need a reliable charging solution during their trips.

The built-in dual super bright flashlights and the included compass carabiner added extra utility to the power bank, making it an even more valuable outdoor companion.
Unfortunately, I did notice that the solar charging capabilities could be slow and unreliable in certain conditions, so I recommend charging it using a wall outlet when possible. Additionally, it may not be compatible with all mobile devices, so double-check compatibility before purchasing. Lastly, though the outer case is well-built and functional, some users may find it a bit bulky for their preferences.
Overall, the BLAVOR Solar Charger Power Bank is a terrific choice for anyone planning an outdoor adventure and needing a reliable, efficient charging solution for their devices.

Solar Power Bank Buying Guide
Capacity
When choosing the best solar power bank for backpacking, I need to consider the capacity of the power bank. The capacity is measured in milliampere-hours (mAh) and indicates the amount of energy the power bank can store. For backpacking, I recommend a capacity between 10,000 and 20,000 mAh to ensure that I have enough power to charge my devices for several days.
Solar Panel Efficiency
Solar panel efficiency is another crucial factor to consider when selecting the ideal solar power bank for backpacking. The efficiency determines the rate at which the solar panels can convert sunlight into electricity. Higher efficiency solar panels allow me to replenish my power banks faster while exposed to sunlight. Look for solar panels with an efficiency of at least 20%.
Size and Weight
When backpacking, every ounce matters. I want to make sure that the solar power bank I choose is compact and lightweight. While larger capacity power banks tend to be heavier and bulkier, look for a balance between capacity and size that fits my backpacking needs.
Durability
Durability is essential when selecting a solar power bank for backpacking, as I need a product that can withstand the elements – such as rain, dust, and occasional drops. Look for power banks with an IP rating, which indicates its resistance to water and dust.
| IP Rating | Protection Level |
|---|---|
| IP64 | Dust-tight and protection from water splashes |
| IP65 | Dust-tight and protection from low-pressure water jets |
| IP66 | Dust-tight and protection from powerful water jets |
| IP67 | Dust-tight and protected from immersion in water up to 1 meter |
Output Ports
Consider the number and type of output ports available on the solar power bank. I want to make sure that it has the right connections for my devices, such as USB-A, USB-C, or micro USB. More output ports also allow charging multiple devices simultaneously, which can save time.
By keeping these factors in mind, you can choose the best solar power bank for your backpacking adventures!
