Using the Goal Zero Torch 500 is a breeze. You can switch between spotlight and floodlight modes according to your needs. To charge it, you have two options. You can place it under the sun to use the built - in solar panel or plug it into a USB source. When your phone runs out of power, just connect it to the torch to get a quick charge. Remember, although it has an IP67 rating and is waterproof, don't keep it submerged in water for too long. To maintain it, keep it clean and store it in a dry place when not in use. This will help ensure it stays in good condition and is ready for your next emergency.
