2. Solar Panel Efficiency

Surprisingly all solar panels are not efficient. Most of the solar panels convert just 14% of total solar energy that reaches them. But solar panels that are recently available are becoming much better.

There are best solar chargers that have panels with an efficiency of 23%. Generally, it is better to have a solar charger with higher solar panel efficiency.

3. Number Of Ports

A solar phone charger should have a minimum of two charging ports. If possible, buy a solar-powered phone charger with three ports.

If you happen to have multiple devices or you want to charge someone else’s phone at the same time, these extra USB ports can be very useful. With that, you will be able to charge two or three devices simultaneously.

4. Fast Charging

Generally, go for a solar cell phone charger that has fast-charging technology. Fast charging reduces the charging time even when 2 or 3 devices are plugged in at the same time.

Anker has PowerIQ technology, while RAVPower calls its technology iSmart.

5. Power Input

In terms of power input, there are two types of solar phone chargers. They are those that can be powered by solar energy only and those that can be powered either on solar or a standard power outlet.

Solar only chargers are best suited for hiking and camping. They have higher capacity and efficiency solar panels that can provide enough power to keep your phone charged when you are on a short trip.

6. Integrated Battery Pack

Solar-powered chargers with an integrated battery pack are usually dual input chargers. They are charged mainly through an electrical outlet. They are not the low-capacity solar panels.

If you spend a lot of time traveling, then we recommend a solar-powered charger with an integrated battery pack.

Instead, you can buy a solar-only charger and charge a couple of external battery packs with it to be used when there is no sunshine.

7. Portability

Buy a solar-powered charger that is easy to carry around in your travel bag or backpack. It should have Velcro, hooks, or some way to attach it to your bag while traveling. Any solar charger weighing a pound or more is too much.

8. Weatherproofing

If you are outdoors most of the time, the charger you buy must withstand the worst outdoor conditions. This includes water and dust. Check whether the solar-powered charger is proofed from dust and water.

9. Accessories

Finally, make sure what accessories the solar charger comes with. It should, at the very least, include one or two USB charging outlets.

Best Solar Chargers – Your pick?

Deciding on the right solar charger can be a challenging task. All are unique in their way. Just keep one thing in mind – that is to match the wattage/mAh to the devices you most frequently will charge.

Purpose of a solar charger is to keep your devices charged and being compatible according to your luggage. Check the size and weight as well, along with the power storage capacity of the solar charger.

It should be compatible with your plans. If you have an oversized charger, it will not help you, particularly if you want the light load on the trail.
