CPU Monkey’s Cool Gadget Collection #4: Camping & Solar Energy Chargers

 CPU Monkey’s Cool Gadget Collection #4: Camping & Solar Energy Chargers


  We asked Our Favorite friend CPU Monkey to check the Worldwide Market for Solar Charging Devices.

  The Task has two different solutions.

  1.) Unbuffered, Solar Powering Device:

  This means the charged devices can use the solar power if they are exposed direct sunlight:

  2.) Battery Bank Buffered Solar Powering Device:

  This means the sunlight power will charge the power Bank built-in battery pack when there is direct sunlight available.

  Any of these devices incorporate and MPPT feature, for optimal power extraction.

  Let’s see CPU Monkey’s finds:
