Interesting Facts About Solar Power Banks
- Monocrystalline panels convert sunlight at \~20 % efficiency—about 3 × higher than the amorphous cells in many budget chargers.
- A 16 000 mAh pack stores roughly 59 Wh , comparable to a mid-size laptop battery.
- Using wireless charging is \~10 % less efficient than cables; a built-in Qi pad saves you carrying a separate puck but does drain capacity faster.
- PD (Power Delivery) negotiates voltage dynamically, so a phone charges to 50 % up to 70 % faster than with standard 5 V ⎓ 2 A bricks.
- Foldable solar panels originated from NASA satellite arrays ; consumer versions now use the same PET-laminated cells for durability without the cost of space-grade gallium arsenide.
