Buyer’s Guide

We can’t tell you for sure if purchasing a solar power bank without sufficient information is going to lead to good results. Yes, you could end up with a good model, but at what price? The best thing to do when shopping for items you’re not too familiar with is to seek a guide.

This section goes over the most important features people should look for in their solar chargers.

1. Portability

Your ability to carry any item you bring with you on an outdoor excursion or camping trip is likely at the top of your list. A solar power bank is no exception to that.

You’ll want a solar charger that you can effortlessly carry around with you. This is especially true for newbie campers since navigating the outdoors can already pose some level of difficulty in itself.

2. Charging Capacity

Before you purchase a solar power bank, you’ve got to consider how capable it is at powering the gadgets you’ll be bringing with you on your trip.

There are awesome models with just enough charging capacity for one or two devices. If you want an effective charger for, let’s say, four devices at a time, you should pick a unit with around 20W or more power delivery capacity.

3. Inbuilt or External Battery

How much power can the battery hold? That would depend on the mAh, which, depending on your power bank, could be anywhere from 10,000 to 26,800, but that’s just based on our list.

If you’re going on a long trip with several gadgets that need regular charging, then a heavier duty charger that can hold up to 26,800 mAh and comes with an external battery would be the best choice. Otherwise, for light nature trips, you can simply go for a model that has an inbuilt battery with 10,000 mAh power capacity.

4. Number of Ports

Most campers don’t really bring a lot of technology with them on their trips to the wilderness. If you do, and you need to make sure they are all charged effectively, then choose a model that has several ports, preferably with both type C and micro USB options. That way, you can conveniently charge multiple devices effectively and efficiently.

5. Weight

Ideally, you’ll want to pick solar power banks that are highly durable yet lightweight. The weight of the power bank usually tells us what excursions its best for.

For instance, the lightest ones are typically meant for short nature trips, while the bulkier and heavier-duty units are ideal for lengthy expeditions into the wilderness.

FAQs

1. What are solar power banks?

The biggest difference between a solar power bank and an ordinary one lies in their charging options. Granted, solar power banks are usually slower and are recommended only for emergency situations.

Aside from having the traditional charging option where you just plug the cord into the outlet to load up the device’s battery, a solar power bank has a solar charging feature, wherein it simply needs to be laid out in the sunlight to absorb solar power.

2. How do you charge a solar power bank?

You can either charge a solar power bank traditionally or via solar energy. To charge the traditional way, plug it into an outlet with an electrical power source. Alternatively, you can simply lay it out in the sun to absorb solar energy.

3. How long does it take for a solar power bank to charge?

A good power bank will usually take about six to eight hours to be fully charged.

4. Is a solar battery worth it?

It is very much worth it, particularly for those who go off the grid every once in a while as a choice or out of necessity. Plus, it furthers our efforts to live more sustainably.

5. How long can a power bank hold a charge?

If you have a good power bank, then expect it to hold a charge for up to three to six months without too much loss.

Final Verdict

It is not surprising that every single power bank on our list deserves to be called the best solar power bank of 2019. They all score relatively high in terms of portability, weight, number of ports, and charging capacity.

If a choice needs to be made, however, based on our in-depth analysis of these products, the title for this year’s best choice has to go to the ORYTO Solar Charger. You see it edging all the others in most departments, except weight, which happens to be the area of its slight downfall. Other than that, it really is the ideal partner to have for any outdoor excursion.
