With our increasing reliance on smartphones, cameras, and other portable electronics, staying powered away from shore power is more crucial than ever. 


Running out of juice can quickly turn a fun trip into a stressful, hazardous situation. What if you could be fully charged and connected no matter how far off the grid your travels took you?


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


In today’s post, we will cover: 


  1. Why portable power is necessary 
  2. When portable solar makes sense
  3. Available solutions on the market and their drawbacks
  4. How pairing off-the-shelf systems can reduce 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, portable power is a means of staying connected, taking photos, sending texts, or making phone calls away from an outlet. 


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

For them, power is crucial, allowing them to document their travels, keep in touch with loved ones, make contacts from remote regions, or call for help should an emergency arise while on the trail or in a remote location.


Portable power solutions are practical almost anywhere, including on road trips, at the airport, outdoors, and other situations.


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.


For example, when a professional filmmaker is on location for an extended time, access to grid power isn't possible or 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 more batteries. 

    • While doable, this leads to increased pack weight, and in an emergency, what felt like enough power for the trip might fall short.


2. Solar 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 often throw away a lot of power because they are designed to do different things and rarely work together efficiently.


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.
