Ultra Lightweight Solar Systems
(I Make A Commission For Purchases Made Through The Links Below)
Many electronic devices can be powered by USB alone. So instead of buying a giant solar system, simply buy a few USB Battery Banks, and charge them with a USB Solar Panel! That's it! Super cheap and super lightweight.

USB Battery Banks
You preferably want a fast charging battery bank so that you can capture more solar power. If your solar panel is creating 6 amps, but your charger can only handle 2 amp charge rate, you will have problems. Try to buy multiple battery banks and charge them simultaneously to capture as much power from your solar system as possible.
