reliable power source for extended outdoor adventures
On a recent week-long backpacking trip through the Sierra Nevada, I relied heavily on my solar panel charger to keep my GPS and phone operational. With a 21W output and a built-in 10000mAh battery, this charger was indispensable. It consistently delivered up to 3A per port, ensuring my devices were quickly and efficiently charged under the open sky.
Why It Earned a Spot in My Pack
- Built-in 10000mAh Battery: Provided a reliable reserve of power for use during the night or on cloudy days.
- Dual USB-A & one USB-C Ports: Allowed me to charge multiple devices simultaneously without a hitch.
- Max Output of 3.5A: Ensured fast charging times, reducing downtime and keeping me connected.
- Advanced Safety Features: Kept my devices safe from overcharging and short circuits, even in the most rugged conditions.
Field note: Its lightweight and foldable design made it incredibly easy to pack and carry, proving to be a low-space, high-value item for any outdoor enthusiast.
