It sounds like you're describing a hybrid solar-powered portable charger that offers multiple charging options, which would be perfect for long days outdoors, travel, or emergencies. Here’s how the features might break down:

Key Features:

  1. Solar Charging: The charger can charge itself via solar panels when exposed to sunlight, making it ideal for outdoor use where electricity isn't available.
  2. Wall Charging: You can also charge it through a traditional electrical outlet (plug-in) for faster and more reliable charging when power is available.
  3. Integrated Light Source: Some models even include a built-in LED light or have a design that allows it to charge under a light bulb, taking advantage of any light source.
  4. Multiple Device Charging: It should come with various output ports (USB, USB-C) to charge smartphones, tablets, or other devices simultaneously.
  5. Compact & Durable Design: Since it's designed for outdoor use, it would need to be lightweight, portable, and resistant to water or shocks.

Ideal Use Cases:

  • Outdoor Activities: Great for hiking, camping, or traveling in places where power sources are scarce.
  • Emergency Backup: Perfect for power outages or when you need to keep devices charged during an emergency.
  • Long Days: Ideal for staying charged throughout a busy day without worrying about running out of battery, whether you’re out in nature or away from conventional power sources.

This type of charger combines the best of both worlds: solar power for sustainability and convenience, and traditional charging for reliability when the sun isn't shining.
