3D printed solar charger

This is a solar charger or an emergency light. The case design is open source and can be fabricated on an open source 3-D printer.^[1]

It runs on a 6660 mAh battery. The unit mAh measures the battery's capacity and 6660 represents the battery's ability to deliver 6.6 amps per hour. Amps, is the abbreviation for amperes, that means it gauges the amount of electrons that passes through a given point. In other words, this battery will be able to provide 24 hours of light source to a given object or space, or multiple phone charges. To maximize the charging of this device using solar energy, or photovoltaic methods, the angle of the solar panels can be modified.

This type of technology can be classified as an Open Source Appropriate Technology (OSAT). It is available for any user to view or edit,^[1]and it is a technique that is easy and economically used from readily available materials indigenous to local communities to meet their needs.

Applications

There are many ways the solar charger can be used. Some are mentioned below:

1. Charging various electronic devices such as phones, iPods, or cameras
2. This solar charger is very portable (200mm/20cm in length)
