Battery Chemistry Showdown

• Lithium-Polymer (Li-Po): Slim profile but slightly less stable
• Lithium-Ion (Li-ion): Better energy density, more common

Recent advancements in GaN (Gallium Nitride) technology have revolutionized compact chargers. These palm-sized wonders can now deliver laptop-grade charging speeds without bulk.

Real-World Performance Factors

Through rigorous testing, we've identified three critical performance aspects:

1. Actual vs claimed capacity (typically 60-70% conversion rate)
2. Charging cycle durability (300+ cycles for quality units)
3. Temperature management during simultaneous charging
