Best Solar Power Bank for Backpacking
Most solar power banks are unreliable, poorly made, and stop working soon after purchase.
That’s because most are made overseas with poor quality control.
Due to this fact, it’s difficult to recommend any solar power banks, especially with the reputable Anker brand having discontinued their solar power bank product line.
However, after spending hours researching solar power banks, I’m happy to recommend the option below:
The Only Option
Patriot Power Cell CX
• 8,000mAh capacity (enough to charge an iPhone 14 2.5x)
• x2 USB-A Ports
• x1 USB-C Port
• 1 Year 100% Money-Back Satisfaction Guarantee
• 2 Year Extended Warranty - If anytime in the next 2 years your Patriot Power Cell CX fails to hold a charge due to defects in materials or workmanship, send it back with a note explaining the problem. They’ll ship you a brand-new one FREE!
An Even Better Option
Despite the Patriot Power Cell CX being one of the few good choices when it comes to solar power banks, the design is inherently flawed.
Due to their extremely small solar panels, they’re pretty much useless when they run out of power (which you charged at your house before going backpacking).
Once out of power, it can take days to fully-charge your phone.
Adding to the problem is the fact that lithium-ion batteries don’t like heat. This is why most solar power banks fail; the solar panel and battery are connected and the lithium-ion cells overheat while the panel is in the sun. This causes reduced capacity and/or death to the solar bank in many cases.
Goal Zero solves this problem.
Goal Zero Nomad 10
Purpose-built for backpacking, the Nomad 10 is:
Small - 9.5 x 7.2 x 1.25 in (folded)
Lightweight - 1.12 lbs
Easily mounted to the back of a pack - using the cut-outs on each corner.
Foldable - space efficient for storage.
The 10W solar panel can charge an iPhone 14 in 2.5-5 hours depending on elevation, temperature, time of year, angle and position to the sun.
To help increase efficiency and charging times, the Nomad 10 includes a built-in kickstand that clicks into place at multiple angles, so you can position your panel for optimal solar collection and ensure it stays put.
The panel has an integrated USB-A port on the back to directly charge your phone, headlamp, or other device.
Alternatively, you can purchase one of their Flip Power Banks to store power for later use (it charges while plugged into the integrated USB port).
