Power, there never seems to be enough to go around. We need it for an increasing number of things. Our smartphones, smartwatches, cameras, headphones, speakers, etc.


In a time where seemingly everything requires electricity, how do you stay connected when you’re away?


Today's post answers that question by discussing: 


  1. Why portable power is necessary 
  2. When portable solar makes sense
  3. The available solutions on the market
  4. How pairing off-the-shelf systems can negatively impact efficiency 
  5. Why the LightSaver line is a simple and effective solution for portable power needs


Take this blog post with you!


Why is portable power necessary?

For many, power is a means of staying connected longer and getting more value from electronic 

devices while away from an outlet. 


Taking photos, sending texts, or making phone calls. 


The backpacker, thru-hiker, adventure photographer, and ham radio operator have different needs.

For them, power is crucial, allowing the documentation of their travels, keeping in touch with loved ones, making contacts from remote regions, or calling for help should an emergency arise while on the trail or in a remote location.


Portable power solutions make sense almost anywhere, including on road trips, at the airport, outdoors, and beyond.


When do portable solar solutions make sense? 


When your power needs are beyond short-term (topping off a cell phone here, charging a small action camera there) and span many days, a solar solution makes a lot of sense.


When a professional filmmaker is on location for an extended time, and access to grid power isn't possible.


When a hiker embarks on a months-long journey and is completely disconnected from conventional power sources.


Potential solutions to this portable power problem


  1. Bring enough batteries on your trip to keep your devices juiced up. While doable, this leads to increased pack weight, and in an emergency, what felt like enough power for the trip might fall short.

  2. Use a solar panel to charge your device directly. This can work but requires leaving your device plugged in and in the sun.

  3. Pair a portable solar panel with an off-the-shelf battery. These systems can "work" but throw away a lot of power because they are designed to do different things and rarely work together efficiently. Not only is this option inefficient, but with cabling and frequently a breakable solar panel and a separate battery, these systems are cumbersome, heavy, and frustrating.


Is there a better way to stay powered during your next family vacation, an all-important backpacking trip, or a thru-hike? 


There is.


To make the solar charging process more accessible, we developed LightSaver Portable Solar Chargers.


This line of chargers features simple operation, integrated batteries and lightweight construction.


There are two options designed to meet power needs from small to large. 


The LightSaver Portable Solar Charger is an ultra-light integrated solution ideal for someone needing minimal, lightweight, portable power that can fit in their pocket.
