Having an output of 5V USB and 18V DC port, you’ll be getting the ideal solar charger that will guarantee battery uptime for you during travel, hiking or other busy outdoor activities.

This solar charger is compatible with iPhones, iPads, Tablets, Notebooks, Samsung galaxy and other tablets. It comes in two different colors (black and camouflage), with a charge controller, making it the perfect plug-and-play solution for quick charging. It doesn’t work as a power bank.

Usually, Sunkingdom portable solar panels will charge your gadgets on the spot when you plug your devices in the 5V USB or 18V DC port. The solar output efficiency is about 19% which should be enough to recharge your battery during sunny hours.

These portable solar panels ensure that all your fun outdoor activities are not cut short by battery shortage or lack of an electricity source. With this charger, you can have your video/digital camera to capture special camping, holidaying and hiking moments all day long without concern for battery life.

There are various other models of the Sunkingdom solar panel charger and even solar batteries and other accessories. If you’re an adventurous person, this solar panel charger will ease your troubles and help keep your gadget up to capture those beautiful and interesting moments of your adventures.

My rating:


Portable and performs well in direct noontime sunlight. The outdoor weather proof fabric is awesome and great.


Can be a bit slow in powering devices that are already down. The lower models may fail to lift battery (you’ll have to get the ones with bigger watts capacity). Some gadgets, especially the iPhone may not be compatible as advertised.


Sunkingdom portable solar panels are a great companion to have on your travel and fun outdoor activities. As long as you have your gadget with you, and the sun is up, you’ll be good to go. I’ll also advise that you get the higher models of the Sunkingdom solar panel chargers, maybe the 28W, so as to avoid disappointments and battery shortages. For me, the portability and charging flexibility is top-notch, and you should purchase it for this reason.

Sunkingdom portable solar panels come in various styles and capacities. There is the 28W solar panel which is sized at 36.22 x 0.12 x 18.31 inches and weighs 3.31lbs, the 52W solar panel which is sized at 36.54 x 0.08 x 20.2 inches and weighs 3.86lbs, and the 19.5W solar panel sized at 29.21 x 0.08 x 9.72 inches and weighs 1.62lbs. All the above models do not carry a battery pack. So, if you want to have something like a power bank to store power, you’ll need to purchase an extra battery pack. All Sunkingdom portable solar panels come along with the exclusive powermaxIQ technology, which enables automatic recognition and speeds up charging to maximum current when used under the sun.

Also, you can fold and unfold each of these portable solar panels, because of their lightweight and ultra-compact build, making their outdoor use convenient and comfortable. The solid waterproof mono solar PET fabric provides high-quality water resistance during rainfalls, making sure that your power source remains safe and sound. Almost every gadget will be compatible with this solar charger. You can use the USB or DC port, and you’d be fine. However, there are exceptions concerning the compatibility of gadgets. Take, for example, the Apple device. Most Apple devices carry with it, a unique inner protection electricity microchip design which may inhibit charging if the sunlight is not enough. A good solution to this problem is to purchase the solar panel charger with a high wattage or use the solar panel charger to charge a power bank and then, charge your device with the power bank.

Here are some of the specs explained


The Sunkingdom portable solar panels have a scratch-resistant dull polish surface that prevents easy scratch or dents when in use. Even if you’re charging your phone while mountain climbing, you can be rest-assured that small hits and scratches won’t affect its performance.

Power Source

Since the Sunkingdom solar power phone charger thrives on sufficient sunlight, you have unlimited access to power for charging your device as much as you can without paying a dime. Also, this affords you the flexibility of doing something else simultaneously as you charge your phone.

You can even charge your phone, listen to music and do some other fun activity that appeal to you. This means that you can have the entertainment from your phone and still enjoy the flexibility to access a limitless power source at the same time.

Voltage regulation

The Sunkingdom portable solar panels do not just provide power from the sun to your phone and leave you to fate. Not so. It is equipped with a voltage regulator that will stabilize the incoming current and preserve the life of your device. So, no more power surges or failures. Once you have your phone connected, you can be rest-assured that you’ll be getting the right kind of power supply.


The Sunkingdom portable solar panels can be used on a variety of devices. With the USB port, you can charge devices that have 5V USB-charging ports such as your smartphones, tablets, ipods, etc. But, note that certain devices will need a higher wattage to get charged. You should also avoid being tempted to expose your device to too much sunlight. Keeping your device directly under the sun over a long period may cause overheating and subsequent damage to your device. Once you can fix your solar panel charger where there is maximum exposure to sunlight ( knapsacks, car roof, windshield, slanted windows, etc.), you can then connect your gadget using a power cord (Which is not included in the package). Once the sunlight is enough, the Sunkingdom portable solar panels will pick, regulate and charge your device.
