Ultrathin Pocket Power Bank for Keychain Carry

Ultrathin Pocket Power Bank for Keychain Carry

The keychain format usually caps at trinket capacity — this ultrathin unit breaks the cap: a 5,200mAh-class 18650 core in a shell slim enough for the pocket, on a ring for the days the pocket stays behind. The everyday-retail middle path: real capacity, real portability, one object.

Key Features

• 5,200mAh-class in ultrathin — the format’s capacity cap broken
• 18650 platform — the documented cell under the shell
