The growing need to stay connected while on-the-go has necessitated the use of portable solar chargers, particularly for outdoor enthusiasts who engage in backpacking activities. This piece will focus on the best portable solar chargers in the market, their features, pros, cons, and how they meet the energy requirements of backpackers.
1. Anker 21W Dual USB Solar Charger
The Anker 21W Dual USB Solar Charger stands out with its impressive 21-watt power output and three solar panels. With a conversion efficiency of 21 to 23.5 percent, it unsurprisingly ranks as one of the best in energy production among portable solar chargers. Its Fast Charging Technology detects the connected device, delivering the fastest possible charge up to 2.4 amps per port.
The charger is foldable, making it handy and ideal for backpackers who anticipate long hours in the outdoors. It has stainless-steel eye-holes on each corner, allowing easy attachment to backpacks, tents, or trees. Its PET polymer surface also ensures weather-resistant durability. Despite its remarkable power output, the Anker 21W does not have a battery pack to store energy for later use.
2. GOAL ZERO Nomad 7 Plus Solar Panel
Notably compact and user-friendly, the GOAL ZERO Nomad 7 Plus solar panel is an optimal choice for minimalist backpackers. Weighing just 17 ounces, it is one of the lightest solar chargers available. Its innovative design includes an LED indicator displaying solar intensity and providing feedback on the charging speed.
This portable solar charger also has a removable kickstand to help position it for optimal solar capture. The GOAL ZERO Nomad 7 Plus allows for direct charging of USB and 12V devices, but similar to the Anker 21W, it does not have a built-in battery pack. The maximum power output is 7 watts, substantially less than the Anker 21W, but remains a practical option for its size and weight.
3. BigBlue 28W Portable Solar Charger
The BigBlue 28W Portable Solar Charger is known for its impressive power output and three USB ports. It delivers up to 2.4 amps per port or 4 amps overall under direct sunlight. This feature enables users to charge multiple devices simultaneously.
Due to SmartIC technology, BigBlue can identify connected devices and maximize charging speed while protecting against overcharging. Its weather-resistant design and external battery make it ideal for outdoor use. This charger is a bit heavier than other options, weighing 21 ounces, but its 28-watt power capacity justifies the weight.
4. BioLite SolarPanel 10+
BioLite Solar Panel 10+ strikes a balance between portability and efficiency. This 10-watt system features BioLite’s Optimal Sun System, an integrated sundial aligning with the sun to capture direct rays. A 360-degree kickstand helps stabilize on uneven terrain.
Thanks to a built-in 3000mAh battery, BioLite SolarPanel 10+ can store solar energy, providing users with power even after sundown. With a USB output and micro USB input, charging multiple devices is feasible. The weight of this charger stands at 21 ounces, slightly heavier than some backpackers would prefer but offering a substantial power to weight ratio.
5. Nekteck 21W Portable Solar Panel Charger
The Nekteck 21W Portable Solar Panel Charger offers durability, efficiency, and portability. It has two high-efficiency solar panels that provide up to 21% conversion efficiency. The solar charger uses Smart IC technology, ensuring devices charge safely and quickly.
The lightweight and compact design, weighing only 18 ounces, makes it a backpacker’s dream solar charger. Moreover, the canvas surface and precision stitching withstand rugged use and rainy weather. However, the lack of a built-in battery means you can’t store energy for later use.
In conclusion, these top portable solar chargers for backpackers offer varying levels of efficiency, durability, power output, and portability. While selecting a solar charger, it’s essential to consider individual backpacking needs. Some chargers sacrifice weight for power output and vice versa. Therefore, understanding one’s energy requirements while backpacking is vital. Other factors to consider are the presence of a built-in battery, weather resistance, and price. Thus, whether you’re a minimalist backpacker or require high power output for multiple devices, there’s a portable solar charger to meet your needs.
