Why the winner wins
The top pick balances practical capacity, charging behavior, and carry usability best for most buyers.
When budget is smarter
Budget is usually enough for phone-first use when fast recharging is not a strict requirement.
When specialist is worth it
Specialist routes matter for laptop charging, travel-heavy routines, or rapid multi-device top-ups.
What changes the winner
A different winner becomes correct if your use shifts from occasional phone backup to high-demand multi-device charging.
