Green 12000 mAh pocket bank

The ummz M12 is a compact lithium-polymer power bank rated at 12000 mAh with a maximum 22.5 W output. Four integrated cables — USB-A, Micro-USB, Lightning and USB-C — plus a separate USB-C port and Micro-USB port let you charge up to five devices without carrying extra cords. A smart LED display shows the exact remaining capacity at a glance.

Replaces cable clutter and smaller packs

If you currently carry a lower-capacity bank and a tangle of separate cables for different phones or tablets, this unit consolidates everything into one pocket-sized block. The jump is worth it when you need enough reserve for multiple full phone charges plus the convenience of built-in connectors for every common port type.

12000 mAh reserve with 22.5 W peak

The 12000 mAh cell comfortably delivers several smartphone recharges or a full tablet top-up while the 22.5 W USB-A output and 20 W USB-C cable output keep modern handsets at their fastest wired speeds. It runs out when you need more than about three phone cycles between wall charges or when a laptop-class device demands higher voltage profiles.
