Home solar panels make an unwieldily gift, but the WakaWaka power solar charger will fit in the palm of your eco-friendly dad's hand. The portable device can recharge most smartphones in under two hours using only the power of the sun.

The company originally designed it as a portable, rechargeable light to use in rural parts of the world that rely on inefficient and potentially dangerous kerosene lamps. But any father eyeing life off the grid will appreciate using a renewable source of energy to keep his batteries charged.

WakaWaka's solar charger costs $79, and the company says it uses proceeds to make the product available to off-grid communities around the world at a more affordable charge.
