Let’s discuss the specifications in detail.
Battery and Charging Capacity:
The 8000mAh Lithium Polymer battery is enough to hold power for 4 complete iPhone 5 charging cycles. Lithium Polymer battery is known to last longer due to the fact that it can withstand more than 1000 charging cycles during its lifetime.
Though technically the 8000mAh is more than 5 times the capacity of an iPhone 5, but different losses come into play and reduce the actual capacity of the Sunjack phone power bank. But you probably won’t find the capacity insufficient because of the 14W power source, i.e. the solar panel that comes along sunjack power bank.
The Lithium polymer battery is perfect for solar powered battery chargers not only because of the number of charging cycles it can go through, but also because it’s safe in all sorts of climates and also because of its light weight.
The 14W solar panels are the main reason you should buy the Sunjack Phone. 4 solar panels are sewed into a protective fabric that can be folded into a portable unit, which also has the space to store the battery. The solar panel units are mono crystalline in nature, which generally has a life of 25-30 years. The 4 separate solar panels are connected through wires, but all of the wiring is hidden in the fabric.
The 14W solar panel can charge the 8000mAh battery in about 5 hours if exposed to direct sunlight. But one should keep in mind that the light intensity plays a huge role in deciding the number of watts a solar panel can generate, so if the light intensity is not good, the 8000mAh battery might take more than 5 hours to charge.
Design, Dimensions and Portability:
The Sunjack Phone consists of a battery unit, and a foldable solar panel unit. The solar panel unit is sewn into a protective fabric which can be folded in 4 layers. The 30.75 x 9.25 x 0.45 inches of solar panel unit can be folded into a 6.75 x 9.25 x 1.75 inches, which can easily fit into a travel bag. All the wiring between the solar panels is hidden in the fabric as well.
The battery unit of 8000mAh is separate and has to be connected to the solar panels through an input port. It can also be connected to a wall socket for charging. There’s a compartment for this battery unit in the solar panel unit as well. So while you are travelling, everything can fit into the folded solar panels.
The combined weight of the Sunjack solar powered phone charger is 907g,which is heavier than most of the 8000mAh options, but then again, no other solar charger ensure unlimited power supply for your phone(s).

The output voltage of this solar power phone charger is 5V and the output current is 2A. Most of the cell phones and even tablets have a port of 5V. And since the standard input current for most of the devices is 1A, Sunjack can charge two devices at a time from the inbuilt USB ports.
The 5V 1A output port is compatible with most of the devices. The twoUSB ports allow you to charge your iPhone, iPad, Samsung Galaxy Device or any other android device in existence. You can also charge your digital cameras as most of the cameras have a charging port of 5V.
LED Indicators and Flashlight:

- 1st LED indicator is lit when it is 25% charged.
- 1st and 2nd LED indicators are lit when it is 50% charged.
- 1st, 2nd and 3rd indicators are lit when 75% charged.
- And all charge status LEDs are lit when it’s 100% charged.
