2 Watt Solar Charger Kit

From $25

This lightweight, monocrystalline solar panel has the smallest footprint of any 2-Watt panel on the market and is super tough. It's waterproof, scratch resistant, and UV resistant. If you're looking for a simple and and inexpensive charging solution, this is it.

Charge smartphones and handheld electronics via the Voltaic V15 battery,

Charge a GoPro camera directly from the panel via the MiniUSB adapter.

Applications and Charge Times

The most common application for this kit is to charge smartphones via our V15 battery, but we recommend the 3.4 Watt kit if you want reasonably fast charging. The GoPro camera charges directly from this 2.0 Watt panel via the F3511-MiniUSB adapter.

Approximate Charge Time from 2-Watt Panel**

Voltaic V15 Battery: 19 hours

Smartphone via Voltaic battery: 8-10 hours

Digital Camera: 8-16 hours

**For maximum power output, orient the panels towards the sun. When not angled towards the sun, output will be reduced. Dirt and scratches on the face of the panels will reduce the amount of light hitting the solar cells. Clean the panels with a damp non-abrasive cloth. Charge times are estimated based on optimal conditions and may increase in cloudy weather, high temperatures, or when panels are not angled towards the sun.
