General information and description
A multipurpose solar lantern is a device that ensures indoor and outdoor lighting for individuals and families as well as mobile device charging in camps, settlements, private accommodations, and outdoor settings.
There shall be 2 categories of the multipurpose solar lantern.
A. Solar lantern with mobile device charging cable included in the complete kit.
B. Solar lantern with mobile device charging cable excluded in the complete kit.
Minimum packaged content
A multipurpose solar lantern kit consists of:
1.A seperate solar photovoltaic (PV) panel.
2.A rechargeable battery component.
3.Lamp/ LED lighting component placed behind a transparent/ semi transparent luminous plexiglass screen.
4.Durable housing/casing connected by screws or bolts in a way that allows easy assembly and disassembly.
5.One (USB-A) or optionally multiple external charging ports / jacks.
6.At least one button/switch (on/off/luminous intensity levels).
7.A battery charging cable/ Mobile device charging cable.
8.User/Instruction manual and Warranty card.
Design restrictions/recommendations
•To avoid overheating of the battery, the solar lantern should beseparated from the PV panel.
•It is recommended the entire electronics should be on a single PCB, which can be replaced easily (plug & play) using a simple screwdriver.
•There is a safety provision circuit to avoid overcharging anddeep discharge that would reduce the lifespan of the battery
User-friendly optional features

Material composition
Cables (option 1):PVC-free cables.
Cables (option 2):Cables for solar lantern can be made of PVC (polyvinyl chloride). In this case, no degassing should occur up to 70°C operating temperature.
Solar lantern housingand other structural elements (such as PV pan-el frames) should be made of plastic, such as Acrylonitrile Butadiene Styrene (ABS), Polycarbonate (PC), Polypropylene (PP), or others. Al-
ternatively, a PV panel frames can be made of aluminum. The mate- rials of the housing should be sustainable and environment friendly. Products must contain less total plastic and the highest percentage of post-consumer recycled (PCR) plastic. The content of recycled plastic should be proved by a sustainability certifcate. The Lifecy- cle Analysis/ Product Environment Profle should be conducted and should be within acceptable sustainability limits. Restricted colors: no military/camoufaged colors are to be used.
