Portable solar charger review
What is the best solar charger for your phone, tablet, and other small electronics when off the grid? To
find out, we took ten contenders and put them in head-to-head tests while on trips all around the
country. From mountaineering on Denali to sailing off the California coast, we compared them on the
following categories: output power, ease of use, weight, versatility, and portability. In the end we found
big differences in the panels we tested. Some worked well for all of our needs and some barely charged
anything. We also found there is not one best panel for all needs. Read on to find out which is the best
solar charger for your application. portable solar charger
We hope that this review will help illuminate some of the pros, cons, and glitches of solar charging
systems. Our our goes more in depth on the different types of panels on the market The modern
outdoor enthusiast is a very different beast from the climbers, backpackers, kayakers, hunters, and
anglers (etc.) of half a century ago. Even 10 years is plenty to have completely revolutionized the way we
think about technology in the backcountry. Today, many climbers carry route beta on their phones, and
lots of hikers forego an expensive GPS and just use a $20 smartphone app to mark waypoints and set
tracks.
The only catch: compared to a handheld GPS, most smartphones don't pass muster on battery life.
Otherwise, those apps are pretty impressive. But with today's selection of solar charging options, this
does not have to be a problem (unless you are short on sunshine). Solar panels now range from
elaborate and spendy to ultra-affordable and pocket-sized. Some are the same size or even smaller than
your smartphone itself. We're not sure what this means yet for the GPS companies, but this review will
give you an idea of how to navigate the rapidly expanding technological world of solar charging devices.
Check out our complete Solar Charger Review for a comparison of all the products we reviewed.
Understanding the technical terms associated with your solar device will help you interpret the
advertised power and whether or not it will fit your needs. The best way to think about the various units
of electricity are in analogy to plumbing. Think of voltage as the water pressure, current (measured in
amps) as the flow rate, and resistance (ohms) as the pipe size. .
Output Power
At best, the output power of your device will have a marked impact on your stress level--at worst, it
could mean the difference between charging a device and not. Be sure to match your needs to your
amps (a 2.1 amp USB port will charge an iPad more efficiently than the 1.3 amp port), and your use to
your watts. portable solar charger for laptop
An important practical consideration here is how many bright and sunny daylight hours you expect to
enjoy--and, realistically, how many of those hours you can have your solar charger out soaking up some
rays. Will you be in the Alaska Range in the summer where daylight is abundant but storm cycles are
too? Will you be in the rainy Pacific Northwet (not a typo) where the sky is frequently shrouded in rain

clouds? In these cases, you may want a fast-charging, powerful panel with high wattage to charge your
devices in a hurry, to take full advantage for those special moments when that sunlight peeks out from
behind the clouds.
Or, perhaps you live in the desert where it is always sunny and dry but you have to carry your weekend's
water supply on your back, so weight is at a premium. A smaller panel will likely suffice, if you're able to
set it out in full sun for a longer amount of time.
