FL-FB051 Slim 10000mAh Pocket Power Bank
15mm thin in four colours, 2.1A in and out
FL-FB051 is the straightforward volume model: 10000mAh, 2.1A in and 2.1A out, in a 140 x 68 x 15mm slab that slides into a jacket pocket.
Four stock colours - Black, White, Pink and Green - make it easy to run a single production batch across several campaigns, or to give each market its own colour without a separate tooling charge.

Why Buyers Choose This Model
Budget pressure on big runs
A plain 2.1A specification keeps the unit cost predictable when the quantity is in the thousands.

Four colours let one production run serve several campaigns or regions.
Gifts that never get used
At 15mm the pack goes in a pocket rather than a drawer.
