Review on 🌞 Foxelli Triple USB Solar Charger 21W - Portable: Versatile and Efficient Charging Solution for Your Devices by Jessica Moore

Not on the track yet, backyard test on a cloudy day. Set it up on a picnic table without worrying about where the sun is as it was behind the clouds anyway. Plus in actual use, if you're not at your destination during the day, who has the time or energy to maintain optimal alignment? The LED indicator lit up immediately. All 3 ports are tested as power supplies for my LED test chip. When I connected my Android phone it said it was charging. It appears to be constructed well enough to handle reasonable usage. As with any piece of gear, survivability increases if you are careful.
