Features to Consider Before Buying

Although knowing how solar chargers work is quite complicated, there are still some important characteristics easy to identify that you should be aware of if you do not want to end up buying useless stuff. Since we are here to help, we have written about those aspects; so, read on and learn a bit more about solar chargers.

Capacity and Efficiency

The capacity of a battery is measured in milliamp hours (mAh). The more milliamp hours a solar charger has, the longer it will be able to charge your device. Many portable solar chargers come equipped with a lithium ion battery that then charges your phone, camera, tablet and more.

Solar Charger Capacity

Another thing to look for in a solar charger is how efficiently it converts sunlight into electric energy to power your devices. A higher efficiency is better, and most portable solar chargers average is around twenty percent efficiency.

Surge Protection

Because sunlight can be a finicky source of power, especially in cloudy or varying conditions, an important feature of a solar charger is that it employs some means of surge protection to protect your device from power surges and changes in output, which can shorten the life of your device or otherwise damage it.

Solar Charger

This is of course an important consideration if you care for the longevity of your charged devices.

Panel Size

A larger solar panel has a larger surface area necessary for absorbing more sunlight. These large solar panels can be cumbersome to carry and use in the outdoors, so most designs are able to fold out for absorbing sunlight and then collapse again for portability reasons.

This will all boil down to your personal needs. If you are into lightweight backpacking, you will surely require a smaller charger with minimal charging surface.

Recharging Methods

Especially in the cases of smaller solar chargers, sunlight is often not the only means of gaining electricity; some designs are able to be plugged into a computer or outlet to obtain a charge much more quickly than by simply being placed in the sunlight.

Having the ability to charge your solar chargers other than sunlight is always a good thing.

Weight and Portability

If you are looking to take a solar charger on your outdoor adventures, you will want something that is easy to carry and won’t weigh you down. When comparing weight, make sure that you compare apples to apples. There are many cases where the manufacturers only list the weight of the panel or including the accessories.

Solar Charger Panels

In terms of portability, there are models that feature integrated pockets that you can use to stash your device. Others don’t have a storage system but features a compact design which you can easily fit in your backpack or even back pocket.

Best Products on Today’s Market

Whether you need it for an emergency or just a way to keep your camera or phone charged when enjoying outdoor activities (music festivals, fairs, beach days, etc) having a solar charger on hand is a great idea due to its versatility. That being said, after a long research, we have selected what we believe are the best solar charging products on today’s market. Those are the following.

Poweradd High Efficiency Solar Charger

Price: Approx. $46Poweradd High Efficency

Weight: 20.8 ounces

Dimensions: 31 x 10.4 x 0.1 inches

Specific features: PowerSI technology; PET laminated solar panels; high wear PVC fabric; waterproof and weather proof

Best use: Hiking, backpacking, festivals, other outdoor events

The Poweradd High Efficiency Solar Charger has a high level of efficiency for energy conversion from solar energy to power your devices. While many solar chargers have efficiencies of under 20%, the Poweradd solar charger has an efficiency up to 23.5%.

In addition to this high efficiency, the Poweradd charger has a voltage regulator to help protect your device from irregular current and voltage, which happen with most solar chargers because of the irregular nature of sunlight.

The max output for this solar charger is 5 V/4 A and it is foldable for easy portability. This device comes with a USB output port so it can be used to charge a wide variety of electronic devices including iPhones, iPads, GoPros, MP3 players and external batteries.

Like most solar chargers, this device works best when it is placed under direct sunlight. However, it also includes a pocket for device storage to keep the charging device out of the direct sunlight as well.

According to some reviews, when the sunlight hits directly this unit, it charges really slowly, so it is better to leave it a long time in the sun before going on a backpacking trip. Also, people say that it charges devices very slowly, and that it is bulky.

PROS:

  • High efficiency for energy conversion
  • Voltage regulator
  • Pocket for device storage
 CONS:

  • Bulky
  • Unit charges slowly with sunlight

Weight: 16.9 ounces

Dimensions: 16.1 x 12.1 x 0.12 inches

Specific features: iSolar technology; high efficiency; dual USB ports

Best use: Hiking, camping, hunting, emergency use

Like the Poweradd solar charger, the X-Dragon SolarIQ Solar Charger design also boasts a high efficiency for charging your devices. When placed in direct sunlight, the X-Dragon can attain efficiencies of 22 – 25% conversion. Its dual USB ports are compatible with any 5 V USB device, including Smartphones, tablets, PlayStation Portables, Bluetooth speakers and Bluetooth headphones. The maximum output of this device is 5 V/2 A. It features short circuit and surge protection to keep your devices safe from electronic malfunction

Also, it comes with an 18 month product warranty. In addition to the X-Dragon’s foldable design, it also includes a free hook and eyelets so you can hang it on backpacks while hiking. While the best way to achieve maximum charging potential is by laying the device on the ground in direct sunlight, you will still get some charge by hanging it from your pack while you hike in open, sunny areas.

People who have bought this product say that they are not completely pleased with it since they had to wait a long time to actually charge their phones. Also, they say that it is recommended for people with devices that do not consume too much battery, and that the plastic and the panels are not as durable as they should.

PROS:

  • High efficiency conversion
  • Short circuit protection
  • Hook and eyelets
 CONS:

  • Charges slowly
  • Better for smaller devices
  • Not durable enough

Related: We also recommend the X-Dragon External Battery Bag. It is a great way to carry most power banks, external batteries and even phones since it is weatherproof, has a slim and compact design, it is very fashionable and really sturdy, so you can be sure your devices will be protected from scratches.

SportsCentre Easyacc Portable Solar Charger

Price: Approx. $30EasyAcc

Weight: 14.1 ounces

Dimensions: 10.2 x 8 x 1.4 inches

Specific features: Lightweight, designed to charge smartphones or external batteries

Best use: First time solar panel user

The SportsCentre Easyacc Portable Solar Charger has a smaller power capacity than some of the other solar chargers we have included in this review. Unlike the previous two solar chargers, this solar charger is not well equipped to charge larger devices such as tablets. However, its relative light weight makes it a good option for charging when trying to save weight. In full sun, you can expect to receive 5.66 V and 1 A output.

Like the X-Dragon, this solar charger comes with holes on the corner to assist in attaching it to packs, trees, and other places you might want to hang it for charging. While full sun is the best place to obtain maximum charging capacity, it is possible to use this solar charger panel indoors under incandescent lights.

One thing to be aware of is that this solar charger panel is not designed to protect against power surges, so one alternative can be to use it to charge external batteries and then use those to charge your devices. Also, they materials used to build this unit are not the stronger ones, and the charging speed is not as fast as it should.

PROS:

  • Lightweight
  • Can be hanged on most surfaces
  • Can be used in the indoors
 CONS:

  • Does not have power protection
  • Materials not sturdy enough
  • Charges slowly

Related: Another great gear to take on the outdoors is the EasyAcc 20000 mAh Power Bank. It can charge iPhone and Samsung devices up to 5 times with only one full charge, the recharge time is very short, it comes with a protection against overcharging, over current and short circuits, and it is sturdy and very durable.

Weight: 7.1 ounces

Dimensions: 5.3 x 2.8 x 0.59 inches

Specific features: 10,000 mAh high capacity; rain proof and shock-proof design; over charge protection

Best use: Emergency use

The X-Dragon Solar Power Bank is a small and lightweight option for charging cell phones and other USB charged devices. The charging speed is very much subject to the intensity of the sunlight as well as the panel’s conversion rate. However, people say that in optimal conditions, it charges small devices faster than common portable batteries.

Additionally, it is equipped with over charge protection and allows you to charge two devices at once. It’s a good device for casual use and backpacking trips since it has a durable design made of silicone and comes equipped with shock absorption and will hold up against raindrops. Finally, it comes with a long lasting LED flashlight that comes in really handy during the night.

Nevertheless, due to its small size, it has less surface area to collect sunlight. That being said, even when placed in direct sunlight it can take several days to attain a full charge. An alternative is to plug it into a computer to charge it, which only takes a few hours. Also, the cable that comes with it is quite short, and the LED flashlight gets hot after a while.

PROS:

  • Small and lightweight
  • Over charge protection
  • Rain and shock proof
 CONS:

  • Small panel
  • Slowly recharges using solar power

Related: The X-Dragon 20000 mAh Power Bank is another fine gear to take with you on your trips. It is very small and compact; it can fully charge several times a wide range of Smartphones, can detect what device it charges to provide a better performance, has a digital screen and a LED flashlight.

With enough direct sunlight, the Anker charger can provide 2.1 A of charging speed to your devices. Its light weight and portable size make it ideal for long backpacking trips, especially when you can attach it to your pack and use it as you go.

It is compatible with most modern USB charged devices including iPhones and Android phones. Additionally, it comes with elastic loops on each of the corners to assist you in attaching the solar charger to backpacks and trees while hiking or camping. Like some of the other solar panels we have included in this review, this solar charger has a high efficiency up to 23.5%.

However, it is not compatible with iPod Nano, iPod classic, iPod shuffle, Asus tablets or HP TouchPad. Also, some people say that this unit is too big and bulky for backpacking. Finally, even though it has a pocket to put devices in while hiking, it is too small to fit phones, so charging big Smartphones while walking might be difficult.

Price: Approx. $21XTG Solar Charger

Weight: 3.5 ounces

Dimensions: 2.5 x 0.5 x 4.8 inches

Specific features: LED flashlight; capacity indicator for charge; built in lithium ion battery; includes suction cups to mount on a window

Best use: Camping, hiking, backpacking

The XTG Technology Compact Solar Charger is unique from the other devices we have included in this review because it is more of a backup battery than a charger. Due to its small size, it is best used for emergency situations or short backpacking trips where you want to minimize weight and space. It’s about the size of an iPhone, and has a 5 V output.

The built in lithium ion battery can be charged either through solar power or by using the USB cable included to charge it from a computer or other electricity source. It comes with suction cups for window use to obtain sunlight from the outdoors while driving and it also has a bright LED flashlight built in to the unit.

One important thing to note is that when using only solar power, the unit will only charge to 50% of its total capacity. Its 1500 mAh battery will charge USB powered devices, but it is better used for smaller devices, such as phones, rather than large tablets. Finally, people say that once it depletes its charge, it takes a long time to be recharged using either solar or electric power.

PROS:

  • Very small and lightweight
  • Suction cups for windows
  • LED flashlight
 CONS:

  • Cannot charge completely using solar energy
  • Struggles charging big devices
  • Recharges slowly

The flashlight has four settings from 5 to 75 lumen, as well as an SOS emergency beacon. This charger is made of recycled PC – ABS and has great impact resistance.

In addition to being made of recycled material, another feel good merit of the Waka Waka charger is that the company that manufactures this device goes by a buy one, give one policy in which they donate a charger to someone in need. Light can be especially important for those in areas that have limited access to electricity because it allows them longer amounts of time to work on tasks that require light as well as have light in medical and other emergencies.

Before you buy this unit, you should consider that it takes a long time to be fully recharged. Also, if the unit you are trying to charge has a big battery, this solar charger might not take it to 100%. Finally, the circuitry is “two way”, so you have to be aware that it might drain your device’s battery from time to time.

PROS:
