Things To Consider Before Buying

Best you go out and buy a solar phone charger, you should keep in mind the following factors.


This is a number one feature to have in mind since most of the times that you will be using solar chargers, you would have to position them in an open space with enough solar light to actually charge it, so you have to make sure the unit is waterproof, dust proof and resistant to corrosion and rusting


Another aspect to consider when choosing solar chargers is how small and compact they are. Even when most units can be folded to reduce their size, some of them might still be too bulky for taking with you on trips, so pay attention and try to buy the perfect match between size and quality.

If you want maximum reliability, you need a solar charger that won’t disappoint in terms of durability. The charger should be strong enough to handle any potential damage and being dropped. This is especially true if you’re going to use outdoors like for camping or hiking.

Best Products On Today’S Market

After much research, analyzing of customer reviews, pros and cons, we have come up with a list of solar chargers which have proven themselves worthy to be called one of the best solar phone charger.

Anker PowerPort Solar LiteThe Anker PowerPort Solar Lite

Price: Approx. $50

Weight: 12.5 ounces

Dimensions: 11.0 x 6.3 x 0.7 inches

Specific features: Output: DC 5V/2.1 A, 15W, USB cable, Pouch with Velcro closure

Best use: For people who want to power up their device when in an emergency situation or off the grid

The Anker PowerPort Solar Lite is a very good charger since in its closed state, it’s no bigger than a paperback novel, and, if your plan is to remain in the outback for more than a week, this solar charger can provide up to 2 to 3 hours of battery life. Also, it has 2 USB charging ports.

Even in the shade or not in direct sunlight, they still give out power. It has a fast charging technology that replicates your device’s charging protocol, it is made with very rugged plastic loops on all four corners which makes attaching them to your backpack, tree, or tent as easy as pie and it has a short circuit and power surge technology that keeps you and your devices safe.

There are a few things that you should consider about this solar charger. First of all, it does not put out as much output as their manufacturers claim. In fact, don’t expect to get full capacity charging from both USB ports simultaneously. Another minor setback is that since it has such a small surface area, it works best when aimed directly at the sun every two hours or so since it’s prone to slow charging.

The other minor setback is the fact that the Velcro enclosure isn’t too secure, so there’s the possibility of your phones, cables or other stuff, falling out of the pouch. Aside from that, applause is in effect. The last drawback would be that it works only with USB devices.

So if you’re an outdoor enthusiast looking to juice your device with jack ports, you’d be sorely disappointed that this solar charger isn’t for you.


  • 2 USB charging ports
  • Durable
  • Replicates your device’s charging protocol


  • Charges slowly
  • Unsecure Velcro enclosure
  • Works only with USB devices

Related: The Anker 24W Dual USB Car Charger is a great gear to have in your car since it charges fast most of devices, has a safety system, is really compact and has two USB ports.

RAVPower 16W Solar ChargerRAVPower 16W Solar Charger

Price: Approx. $57

Weight: 35 ounces

Dimensions: 7.48 x 10.24 inches

Specific features: Output: 5v / 2A + 5v / 1A, 16w, user guide, 2 USB charging cables, 2 USB charging ports, weatherproof nylon, 3 solar panels

Best use: For larger devices such as tablets, iPads, etc. most likely in car camping situations, on the beach, mountaineering, long distance travel, etc

The highly efficient solar cells of the RAVPower 16W Solar Charger convert up to 21.5 – 23.5% of solar power into free energy. It can charge up to 2 USB devices simultaneously since each USB port delivers about 2 amps of juicing power, which can charge an iPad at a reasonable rate, and when both USB ports are used together they generate an output of 3 amps total. It is small yet powerful and has a simple foldable design

Having 3 solar panels increase the amount of energy intake, so you will not need to carry along an external battery. The four green clips that it comes with are useful, as they allow you to attach the solar charger to your pack while you trek, or some other stabilizing mechanism to drain more solar energy. Additionally, it has the iSmart technology, which allows the charger to identify and adapt to the device you need to charge.

This solar charger, based on some reviews, is not the best companion for lightweights as it is bulky and heavy and does take up some storage space in your pack. Some people claim that the RAV 16W does not charge their iPhone 6 since it shows the error message ‘accessory not compatible’.

Some other customers claim that this product either didn’t work at all or didn’t deliver as much output as advertised or was expected to, and that it didn’t deliver the full 16w as advertised.


  • 2 USB ports and cables
  • Simple and foldable design
  • High energy intake


  • Bulky and heavy
  • Not for iPhone 6
  • Do not deliver the amount of Watts advertised

Related: We also recommend the Solar Charger RAVPower 24W since this one has three USB ports equipped with iSmart technology, is constructed with a durable and waterproof material, and it is really lightweight and portable.

Weight: 24 ounces

Dimensions: 8.66 x 4.92 x 0.87 inches

Best use: Weekend outings, short camping trips, hiking, mountaineering, emergency backup

The PowerAdd Apollo Pro Solar Charger is easy to use and very portable so it can fit in a pack quite comfortably. You could fully recharge an iPad 3 twice with this solar charger or fully recharge a typical laptop once. It is advised to fully recharge the Apollo Pro prior to its first use in order to activate the battery, which will take about 26 – 38 hours in bright sunlight. Once you have done that, it can be pre charged from wall power.

The advantage of the high capacity batteries is that you can pre charge them at home before a short camping trip, and then keep topping them off using your Apollo Pro. The 4 LED indicators make it easy to know how much source you have and when not in use for about 30 seconds, this charger will automatically shut down if no device is connected.

Though this solar charger has its highlights, it has a few drawbacks. It takes too long to pre charge, it’s pricey compared to other USB solar chargers, and it can’t charge a device while also being in the sun.

Some people also claim that the unit did not work properly on arrival and that some of those which did, would not work after the charge had drained.


  • Can be plug to a wall power
  • 4 LED indicators
  • Resting mode


  • Too long to pre charge

Additionally, it is the most lightweight product from this list, weighing less than 6 ounces (170 g), so it can be taken on any outdoor activity with no problem.

It is compatible with most kinds of 5v USB charged devices and, when compared to other devices, it did perform well as far as charging devices go. It will fit comfortably into a back pocket or hook onto a backpack using the wrist strap, and it comes with 2 USB ports.

The solar charging function of this device is however reported to be quite unreliable as it may take several days of bright sunlight to actually get even 25% of juice. It is advisable to use the solar charging function as a back up to top off devices once they’ve already been charged.

Some buyers have said that this unit takes too long to charge any device, that once it has lost the power completely it just cannot be recharged again, and that the power is drained too quickly from the charger.


  • 2 USB ports

The eyehole hook design makes it easy to carry around on your pack when using the carabineer.

It’s a well designed portable solar panel product that meets the challenges of any off grid trip, as long as you get stable sunlight of course. The compact and portable solar panel is smaller and more powerful than comparable panels on the market.

It is claimed to be able to charge smartphones in around 1 to 2 hours provided that it’s exposed to direct sunlight and it’s free from shade. Additionally, the panels have a removable kickstand that gives you the option to angle the unit better towards the sun.

Some users have claimed that the device do not charge their phones. In fact, they say that it simply keeps them from going completely dead. Also, this solar charger requires a Goal Zero Guide 10 battery pack to charge an iPhone.

It also has a large storage pouch for cables, devices and any other accessories you may need to store in there.

However, when trying to charge an iPhone 5 or 6 with this unit, it shows the following message: ‘this device is not supported’, so if you have any of those phones, it is better not take the risk. Also people say that you need to expose the 3 panels directly to the sun to actually get it charge, and that the loops are made of a weak material.

Sean was backpacking since he was 7. He was born close to the RMNP and his father was a ranger, so life surrounded by mountains and wildlife is a norm for Colorado. He likes to explore, but prefers to stay in USA. In his opinion, there are too many trails and options in US to go abroad.
