The Solpro HELIOS SMART (White) is a solar powered smart charger. You can use
it just like you would any other USB battery bank. Charge the internal
5,000mAh battery and keep your mobile devices powered while you're on the go.
You can also use the patent-pending tri-fold solar panel array to charge the
internal battery. With three high-efficiency solar panels, maximum power point
tracking, and our smart charge algorithm Helios can collect enough solar
energy in 90 minutes to charge a standard smartphone. Helios has two USB
output ports and one USB input port. The microUSB port can be used to charge
the internal battery. It can charge off your laptop, desktop computer, and
from a standard electrical outlet. The 1A output port can charge any USB
powered device, recommended for wearables and most smartphones. The 2.1A
output port can also charge any USB powered device and is recommended for use
with tablets. Open the solar panels wherever there is sunlight and point them
towards the sun.
