Portable Solar Charger For Festivals

1. Confirm your device power needs. Check each device’s input (W) or charging spec (e.g., 5V/3A USB‑C = 15W). Add a 20–30% headroom. 2. Match panel wattage to workloads. 10–20W for phones; 20–40W for tablets/cameras; 60–100W for ultrabooks via USB‑C PD. 3. Size battery capacity by Wh (not just mAh). Weekend kits: 60–100Wh; mobile laptop days: 150–250Wh. Prefer Li‑ion with a robust BMS. 4. Use quality cables. Short, 100W‑rated USB‑C PD cables reduce voltage drop; keep connectors clean and dry. 5. Track the sun. Tilt toward the sun and re‑aim every 45–60 minutes; partial shade can halve real output. 6. Safety & storage. Don’t cover charging batteries, avoid extreme heat, and store packs ~40–60% if unused for a month. 7. Troubleshoot quickly. If output seems low, test with a USB watt meter, swap cables, and check for shading. **Pro tips** • Passthrough charging lets you charge the pack while powering devices. • A simple kickstand or paracord tie boosts harvest on windy days. **CTA** See our curated PD‑ready panels and 100–200Wh battery packs for portable solar charger for festivals.
