Sun-Pak
The Sun-Pak is an experimental solar battery created by Sparkplug. The Sun-Pak is able to absorb enough energy from one hour of sunlight to power a Transformer for 24 hours!
The Sun-Pak Prototype is made of metal and fiberglass, and secured externally to the Transformer it's powering by means of an electronic lock. As a prototype, the Sun-Pak is not a sealed unit; it can easily be rewired for adjustments (such as increased power output) but this also means that the prototype is not waterproof, shockproof, bombproof, or acid-proof.
