Solar or DC Input Charging 
It doesn’t just feature solar charging but an DC5V/2A input too. Not only is it a reliable way to charge on cloudy days, it takes just 8 -9 hours to completely recharge with a 2A/2.4A charger.

15000mAh Capacity Charges Two Devices 
Enjoy a large 15000mAh capacity and two iSmart powered 2.1A ports that offer simultaneous charging. With this much power, you can charge an iPhone 7 4.2 times, an iPhone 7 Plus 3 times, and the Galaxy S8 2.8 times.

Reliable and Bright LED 
The built-in LED light serves as a convenient solution in case you need a light at night; simply hold the power button for 3 seconds to activate / deactivate whenever you need it. The design includes dust and shock protection, as well as built-in overcharge and short circuit safeguards.

3 Steps for Better Use 
1. Do not charge through a glass surface (e.g. a window).
2. Please charge in strong sunlight. Light can be detected in cloudy or indoor environments, but it is not enough to recharge the unit.
3. Do not leave in your vehicle during summer as the heat will affect the battery life.
