Things to Know Before Buying a Solar Charger

Getting a dreaded low battery warning during camping is the worst thing any outdoor enthusiast can imagine. This is where solar-powered battery banks can save the day!

The solar power bank features portable small battery packs charged by the connected small solar panel. This efficient power bank design is all wrapped in a durable rugged yet lightweight outer shell. Although almost all solar power banks share this same basic makeup, their specifics or technology can considerably vary. So, keep the following things in mind before you purchase solar chargers for backpacking.

Battery Capacity

After reading reviews and checking the manufacturer’s reputation, the next obvious thing to consider is the battery capacity. First off, solar power banks are expressed in mAh or milliamp hours. You’ll see a range of battery capacities starting from 2,000 mAh all to 20,000mAh or even higher. This is the amount of electrical energy a power bank can hold.

Most smartphone batteries, digital cameras, and other small electronic devices are between 1000-2000mAh. Larger phones, tablets, and laptops have much larger batteries so always check the battery capacity to know which power bank size to get. A solar power bank with a high mAh rating can hold enough energy to power up your devices multiple times. An average 10,000-12,000 mAh battery capacity can charge an average smartphone 8 times or more; ideal for your weekend getaway to the hilly mountains. For longer trips where you have to be away from a power source for a while, those power banks with more than 20,000mAh capacity are great.

Charging rate

Typically, solar power banks have either 1A or 2A USB outputs running at standard 5V. Power banks that advertise fast-charge or 2x quick charge refer to charging via the 2A port instead of 1A charging that most phones come with. If you have an electronic device that accepts 2A current, then the 2A output on the power bank charges it faster. Plus, it also keeps it running if you need to use it while it’s charging. Some power banks have built-in technology that speeds up charging or prevents overcharging.

Some power banks support rapid charging technology such as Qualcomm quick charge and Samsung fast charge that can power up your devices even more quickly.

Output rating

Based on what you plan to charge, take the output rating of the power bank into consideration. It will take about 3 hours to charge an iPhone 6 at 1 amp output. However, it takes only 2 hours to charge fully at 2.1 amp output. If you plan to recharge the tablet, you’ll want a power bank with a higher output rating of at least 2A.

Charging ports

It is especially important if you plan to charge more than 1 device at once from a solar power bank. Look for a power bank with dual or triple device charging capability. If you own a Qi-compatible device, a solar power bank with Qi-technology allows wireless charging. You don’t even have to carry any connecting or charging cables.

Solar panel

Though almost all solar power banks have an optional USB charging option, Solar charging is still vital when camping outdoors with no power outlet. That is why having a high-quality and highly-efficient solar panel is important. A solar panel with a high energy conversion rate will charge with an internal lithium-polymer battery quicker.

Protection system

It’s important to buy a solar power bank with smart protection circuitry to prevent damage to your electronic devices. Built-in temperature protection allows the battery to cool off while over-charge protection prevents excessive charging. Over-discharge safety is also essential since it greatly affects the battery’s service life.  Overpower and voltage enhances battery stability by avoiding excessive voltage discharge/charge. Smart built-in chips automatically detect the connected devices and then provide the optimal current. Having short circuit safety means devices and power bank will have automatic protection before any short circuit occurs. This multiple protection structure offers safe and reliable charging on the go.

QiSa, BEARTWO, BLAVOR, and  BLAVORsolar power banks are the best options from a protection perspective with built-in intelligent chips.

Lightweight and portable design

When it comes to backpacking, portability and compact design are what we all look for. Solar power banks that are slim, compact, and lightweight with simple design are perfect to throw in your backpack or purse to keep around in case of emergency. You can even hang it conveniently on your backpack without feeling any extra weight.

Durability

A portable compact design doesn’t mean you have to compromise over durability. Durability is extremely important in terms of outdoor use. The power bank must be strong enough to withstand all outdoor environments. Solar power banks with rugged and water-proof casings are the most durable.

After all this, it comes to your personal preference and style.

Why is energy-transfer not 100% efficient?

Always keep in mind that energy-transfer is not always 100%. There is some charge loss in terms of heat or other factors with the transfer of power.

Same mAh battery capacities don’t show the same performance?

Solar power banks with a similar mAh rating can vary in terms of performance. This is because not all batteries discharge at the same rate and time. It’s true for charging devices that draw a lot of currents and this, in turn, lowers effective capacity.

Conclusion

The worst part of regular power banks is that one can’t rely on them when out exploring as they are not designed to resist outdoor elements. That’s where the solar power bank steps in! It charges from solar energy to offer the necessary power for effortlessly charging your smart devices.

A solar power bank is a must-have for all outdoor aficionados!
